Objectives: This study investigates the effects of 600 mg/day Ashwagandha root extract on physiological stress biomarkers, perception of recovery, muscle strength and aerobic capacity in team sports athletes during pre-season training, a period associated with elevated cortisol and accumulated training stress. Methods: Fifty-six athletes (26.8 ± 4.4 years, 1.74 ± 0.10 m, 79.4 ± 17.3 kg, 11.0 ± 7.1 career years) across rugby, water polo and football were randomly assigned to an Ashwagandha (ASH; n = 28, 14 males and 14 females) or placebo (PLA; n = 28, 14 males and 14 females) group for 42 days. Salivary biomarkers were assessed after training, muscle strength and aerobic capacity were measured during training, and perception of recovery was evaluated with Hooper Index (HI) the following day. Mixed ANOVA was used to determine group × time interactions and Bonferroni post hoc analyses were conducted for multiple pairwise comparisons. Results: In female athletes, salivary cortisol increased significantly in PLA (p = 0.001), while recovery parameters such as the overall HI score (p = 0.001), Delayed Onset Muscle Soreness (DOMS) (p = 0.008) and perception of fatigue (p = 0.026) scores improved significantly in ASH. In males, salivary cortisone increased significantly in PLA (p = 0.022), while Countermovement Jump (CMJ) improved significantly in ASH (p = 0.018). Pull-up performance increased in both PLA (p = 0.004) and ASH (p < 0.0001) in males. Conclusions: Supplementation with 600 mg/day of Ashwagandha root extract for 42 days may stabilise stress biomarkers, improve perception of recovery and enhance muscle strength in team sports athletes during pre-season training. The trial is registered on ClinicalTrials.gov with the ID NCT07041853.

Erratum in Eur J Sport Sci. 2025 May;25(5):e12292. doi: 10.1002/ejsc.12292. Ashwagandha is a supplement with the potential to improve exercise performance. However, research on its impact on female athletes remains limited. This study investigates the effects of ashwagandha on exercise recovery and muscle strength in professional female athletes, addressing a gap in understanding its role in this underrepresented population. Female footballers were randomly assigned to a 600 mg/day ashwagandha root extract group (ASH, n = 15; age: 26.0 ± 4.9 years, height: 1.66 ± 0.1 m, body mass: 61.5 ± 7.5 kg, and career: 15.2 ± 7.4 years) or a placebo group (PLA, n = 15; age: 23.5 ± 5.5 years, height: 1.66 ± 0.1 m, body mass: 61.5 ± 6.0 kg, and career: 13.1 ± 4.9 years). Recovery was assessed with total quality recovery (TQR), Hooper Index (HI) and rate of perceived exertion (RPE). Strength was assessed by hand grip, medicine ball throw (MBT), countermovement jump (CMJ) and peak power. Dietary intake was recorded prior to baseline measurements. Repeated measures ANOVA, Bonferroni test, independent t-tests and ANCOVA were used in the analysis. A significant group × time interaction effect was found for TQR (p = 0.026), with the post-hoc analysis revealing a significant difference between ASH and PLA at 28 days (p = 0.039). Perceived sleep quality from HI improved significantly in ASH compared to PLA (p = 0.038), with a significant change at 14 days. The ANCOVA analysis highlighted the significant influence of carbohydrate intake on hand grip strength (p = 0.005), MBT (p < 0.001) and body mass (p < 0.001). A dosage of 600 mg of ashwagandha root extract for 28 days may improve TQR and enhance perceived sleep quality in female footballers. Future research should investigate the optimal dosage and test across a broader range of athletic populations.

BACKGROUND: Ashwagandha is a well-known Ayurvedic herb used for youthful vigor and wellbeing. This study investigated the effects of 600 mg standardized root extract (>5% withanolides) of Ashwagandha ( Withania somnifera) on muscle size, strength and cardiorespiratory endurance following resistance training. METHODS: In this eight-week, parallel-group, multicenter, randomized, double-blind, placebo-controlled clinical study, 80 healthy male and female participants aged 18-45 years, who engaged in regular physical activity were randomly allocated in a 1:1 ratio to receive Ashwagandha (AG, n=40) 300 mg capsules twice daily for eight weeks, or identical placebo (PB, n=40). Seven (3 AG, 4 PB) participants were excluded due to poor compliance. All participants conducted eight-week resistance training. Study outcomes included muscle strength (1RM bench press and leg extension), muscle size (circumference of arm, chest and upper thigh) and cardio-respiratory endurance (VO 2max) assessed at baseline and at eight weeks. Analysis of covariance (ANCOVA) was used to estimate adjusted differences based on sex, BMI and chest circumference at baseline. RESULTS: AG caused greater improvement in bench press (males: p = 0.0084; females: p = 0.0005), leg press (males: p = 0.0049; females: p = 0.018) and endurance (males: p <0.0001; females: p <0.0001) as compared to PB. Also, greater improvements in muscle girth for arm, chest and thigh were seen in both male and female participants with AG. No adverse events were reported in the study. CONCLUSIONS: Eight weeks of AG root extract supplementation along with resistance training is effective in improving muscle strength, growth and endurance in both male and female participants. AG root extract could be a safer, effective and low-cost alternative for athletes to improve muscle endurance. Copyright: © 2024 Verma N et al.

Withania somnifera Dunal, also known as Indian ginseng, has been in use since ancient times in the management of diabetes mellitus (DM). This systematic review and meta-analysis evaluated the efficacy/effectiveness, safety and tolerability of W. somnifera in managing DM. Literature search (published/unpublished) was performed from inception to April 2019 in guidelines recommended databases. A total of 6 in-vitro, 13 pre-clinical and 5 clinical studies were included for systematic evaluation. W. somnifera treatment in DM significantly restored the altered levels of blood glucose (experimental data; mean difference, -196.27; 95% confidence interval [-220.96, -171.58]; p < .00001) glycosylated haemoglobin (HbA1c), insulin, lipid profile, serum and oxidative stress markers with no safety concerns. The results suggest the potential role of W. somnifera in managing DM. However, the available clinical data are not considerably enough to provide novel and sufficiently robust evidence for the use of W. somnifera in managing DM. To further strength the anti-diabetic profile of W. somnifera, well-designed randomized-controlled trial(s) with a larger sample size and longer duration is warranted with evaluation of its effect primarily on blood glucose, HbA1c and insulin. Future research also needs to elucidate the molecular mechanism(s) of W. somnifera including its active principles in DM. © 2020 John Wiley & Sons, Ltd.

BACKGROUND: Withania somnifera Dunal, commonly known as Indian ginseng, has been in use since ancient times as anti-stress agent, aphrodisiac, for impotence and infertility treatment. PURPOSE: To evaluate the efficacy and safety of W. somnifera treatment in infertile men. STUDY DESIGN: An evidence-based systematic review and meta-analysis using Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. METHODS: Published literature was searched in PubMed/MEDLINE, EMBASE, Scopus, the Cochrane Library, and DHARA. Grey literature was assessed from the WHO International Clinical Trials Registry Platform (http://apps.who.int/trialsearch/) and the US National Institutes of Health (https://clinicaltrials.gov/). RESULTS: Four clinical trials (comprising 5 publications: observational, n = 4; randomized controlled trial [RCT], n = 1) were included in the study. As only one RCT included, meta-analysis of RCT was not performed; however, systematically reviewed data demonstrated statistical (p ≤ .002 versus baseline) increase in sperm concentration (167%), semen volume (59%), and sperm motility (57%) in oligospermic males after 90 days of W. somnifera treatment, as well, serum testosterone (17%) and luteinizing hormone (34%) levels. Meta-analysis of observational (versus pre-treatment) studies showed that W. somnifera treatment significantly improved semen parameters (semen volume: mean difference [MD], 0.28 ml; 95% confidence interval [CI], 0.12 to 0.43; p = .0004; sperm concentration: MD, 13.57 million/ml; 95% CI, 11.12 to 16.01; p < .00001; sperm motility: MD, 8.50%; 95% CI, 7.36 to 9.63; p < .00001) with 14% of pregnancy outcome success rate in normozoospermic men. Meta-analysis findings also evidenced significant improvement in serum hormonal profile, oxidative biomarkers and antioxidant vitamins in seminal plasma. No adverse effects were reported in infertile men taking W. somnifera treatment. CONCLUSION: Due to a small number of eligible studies, the available data, though promising, are too limited to provide novel and sufficiently robust evidence of the benefits of W. somnifera in male infertility. Additional RCTs of high quality with a

BACKGROUND: Acute mountain sickness (AMS) poses a unique and formidable challenge to healthy personnel at high altitudes. OBJECTIVE: This randomized controlled trial (RCT) protocol aimed to assess the effectiveness of Ayurvedic nutritional supplements in conjunction with a yoga protocol in reducing the incidence and severity of AMS among healthy personnel stationed in the challenging high-altitude landscapes of the western Himalayas. METHODS: The proposed open-label, parallel-group RCT was conducted in apparently healthy individuals of any gender aged 18-50 years. The study was conducted at two distinct high-altitude stages within the western Himalayan region: stage I, situated at an elevation ranging from 9000 to 12,000 feet and stage II, spanning 12,000 to 15,000 feet. A total of 1660 participants (n=830 per stage) underwent random assignment in a 1:1 ratio to receive either the existing acclimatization schedule (AS) for high altitude (control group) or the Ayush intervention (Ayush group) in addition to the AS. The participants in the Ayush group received Ayurvedic nutritional supplements, including the Ayur-nutri kit (Ayush poshak yoga, 25 g, and Ayush cardiac care tea, 125 mL), twice daily, along with a yoga protocol (60 min daily) for 120 days. The primary outcome was the incidence of AMS, assessed using the 2018 Lake Louise Scoring System, and the proportion of participants with a Lake Louise Scoring System score of 6 or higher during the first 7 days from baseline. The secondary outcome measures included the proportion of participants with thromboembolic events; changes in coagulation and hemostasis activation markers and proinflammatory markers; and changes in self-reported negative emotional states (depression, anxiety, and stress), sleep quality, and overall quality of life (assessed through Depression Anxiety Stress Scale-21 items, Pittsburgh Sleep Quality Index, and 12-item short-form, respectively) on day 60 and day 120 from baseline. RESULTS: The study was funded in March 2023. The data collection was completed in December 2023. A total of 1660 participants were enrolled in the study. The analysis of the study data is in progress. The study outcom

BACKGROUND: Overweight and obesity are widespread in Mexico, often linked to dyslipidemia and higher cardiovascular risk. The search for safe and effective treatments has promoted interest in natural supplements such as Ashwagandha (Withania somnifera), recognized for its adaptogenic and potential lipid-lowering properties. OBJECTIVE: To assess the impact of Ashwagandha supplementation on serum lipid profiles and anthropometric parameters in Mexican adults with overweight and obesity. METHODS: A double-blind, randomized, placebo-controlled pilot clinical trial was carried out with 43 adults (n = 17 in the control group and n = 21 in the intervention group) over 40 days. Participants followed a monitored diet and received one daily capsule containing 500 mg of Ashwagandha or a placebo, in addition to a guided unrestricted dietary plan. Anthropometric and biochemical measurements were taken at baseline and after the intervention. In silico analysis was also performed to examine the binding affinity of Ashwagandha bioactive compounds to key proteins involved in lipid metabolism. RESULTS: Ashwagandha supplementation did not produce statistically significant changes in body weight, body mass index (BMI), or waist circumference (WC). However, significant reductions were observed in triglyceride and VLDL-c levels (p = 0.0082 and p = 0.0321, respectively). In silico results supported these findings, showing favorable interactions between compounds such as withanolide A and lipid metabolism targets, including AMPK, CETP, and LPL. CONCLUSIONS: Ashwagandha supplementation improved serum lipid profiles in adults with overweight and obesity, suggesting potential lipid-lowering effects when combined with a prescribed dietary plan. Also, it was possible to elucidate some metabolic pathways in which Ashwagandha composition has an influence on producing the reported effects. Further long-term studies with controlled dietary intake are needed to confirm these findings and clarify the underlying molecular mechanisms. © 2025. The Author(s).

BACKGROUND/OBJECTIVES: High-intensity interval training (HIIT) is considered an effective way in improving aerobic capacity and selected health parameters. Ashwagandha is an herb with possible health-promoting properties that may affect metabolism and performance. The aim of this study was to evaluate the effects of ashwagandha supplementation (600 mg/day) during an 8-week HIIT on body composition, lipid profile and hormone levels related to energy homeostasis in healthy young men. METHODS: The study was randomised, double-blind and placebo-controlled (Placebo group, PL, n = 20; ashwagandha, A, n = 18). HIIT was conducted on a rowing ergometer (3 times per week, 5-7 series of 1.5 min at 85-95% of maximum power, with intervals of 1.5 min at 70 W). Body composition (BIA, Tanita TBF 300P), serum lipid profile (tChol, HDL-cholesterol, LDL-cholesterol, TG) and serum levels of adiponectin, asprosin and irisin were analysed before (term 1) and after the8-week study (term 2). Both the lipid and hormonal profiles were measured in three time points: pre- and post-graded exercise test and after 24 h recovery period. RESULTS: Analysis showed no effect of training or supplementation on body composition and lipid profile (p > 0.05). In turn, the 8-week HIIT decreased resting levels of adiponectin and increased irisin levels post-exercise and after 24 h (p < 0.05). CONCLUSIONS: In young, healthy men, an 8-week HIIT programme significantly affects selected hormones related to energy metabolism of adipose (adiponectin) and muscle (irisin) tissues, but ashwagandha supplementation did not significantly affect any of the hormonal parameters analysed.

BACKGROUND AND AIMS: Elevated plasma levels of total homocysteine (Hcy) and S-Adenosylhomocysteine (SAH) are associated with increased risks of neurological and cardiovascular diseases (CVD). Whilst elevated plasma levels of Hcy can be managed through supplementation with B-group vitamins, there are no effective therapies for managing SAH in patients with elevated SAH and normal Hcy. SAH, a by-product of cellular methylation reactions, is considered a more sensitive biomarker for CVD than homocysteine (Hcy). The aim of this study was to determine if a test product containing ashwagandha extract, alpha-glycerylphosphorylcholine and creatine monohydrate, could lower plasma SAH levels in adults with elevated SAH and normal Hcy. METHODS AND RESULTS: In this prospective, randomized, single-blind, placebo-controlled clinical trial, 40 participants with elevated SAH (≥20 nmol/L) and normal Hcy (≤13 μmol/L) were randomized into two groups: 15 participants received the placebo, and 25 participants received the test product. The test product significantly lowered plasma SAH levels by approximately 12% and increased S-Adenosylmethionine (SAM): SAH ratio by approximately 26% after 12 weeks of supplementation compared to baseline. The test product was safe and well-tolerated, with no serious adverse events. No clinically relevant changes in vital signs and safety laboratory parameters were detected. CONCLUSION: This is the first demonstration of a nutritional product's effectiveness in decreasing plasma levels of SAH in otherwise healthy individuals with elevated SAH and normal Hcy. Hence, this test product offers a unique opportunity for investigating the impact of lowering plasma SAH on the risk of developing CVD and other diseases.

BACKGROUND: Withania somnifera (L.) Dunal, commonly known as ashwagandha, is a well-known plant in ayurvedic medicine, widely valued for its therapeutic potential. Although numerous clinical studies have explored its diverse health benefits, limited data are available on the pharmacokinetic (PK) properties and comparative bioavailability of its key bioactive constituents in humans. OBJECTIVE: This study aimed to evaluate and compare the oral bioavailability of 4 commercially standardized ashwagandha extracts under fasting conditions in healthy adults. METHODS: This randomized, double-blind, 4-treatment, 4-period, 4-sequence, single dose, 4-way crossover study was conducted in 16 healthy human volunteers. Participants received a single oral dose of 1 of 4 ashwagandha extracts, with varying compositions of 35% (Withania somnifera [WS]-35) or 10% (WS-10) withanolide glycosides, or 5% (WS-5) or 2.5% (WS-2.5) withanolides, each standardized to deliver 185 mg of total withanolides. Seventeen blood samples were collected over a 24-hour period after dose administration. Plasma concentrations of withanolide A, withanoside IV, withaferin A, and total withanolides were quantified, and PK parameters were calculated. RESULTS: Withania somnifera-35 had significantly superior bioavailability compared with the other extracts. The AUC0-t for total withanolides per gram of WS-35 was 118.28, 226.11, and 267.83 times better than WS-10, WS-5, and WS-2.5 respectively. Withania somnifera-35 exhibited a significantly higher Cmax, longer half-life, extended mean residence time, and lower systemic clearance, attributable to its higher withanolide glycoside content. CONCLUSIONS: These findings emphasize the critical role of withanolide glycosides in determining the PK performance of ashwagandha supplements. The enhanced bioavailability of WS-35 supports its preferential use in therapeutic applications and provides a strong rationale for further investigation into dose-response relationships and the long-term efficacy of standardized, high-bioavailability formulations.

INTRODUCTION: Ashwagandha has multiple medicinal properties and is widely used as a supplement to address various health conditions including stress and anxiety. The bioavailability of Ashwagandha bioactives provide critical information on the biological effects in humans after oral supplementation. METHODS: A randomized, double-blind, single-dose, cross-over comparative oral bioavailability study was conducted in 20 healthy, adult human subjects under fasting conditions. All subjects consumed single dose of ZEN 1.5 (Zenroot™ Ashwagandha 1.5% 125 mg), ASH 5 (Reference product 1-Ashwagandha 5% 600 mg) and ASH 10 (Reference product 2-Ashwagandha 10% 500 mg) as per a randomization schedule. Blood samples were collected at 0.00 h, and at 00.25, 00.50, 00.75, 01.00, 02.00, 03.00, 04.00, 05.00, 06.00, 09.00, 12.00, and 24.00 h post-dose. Total withanolides (consisting of withanoside IV, withanolide A, 12-deoxywithastramonolide, and withaferin A) were quantified in plasma using the LC-MS/MS method and pharmacokinetics parameters like area under the curve, AUC0-t, Cmax, Tmax, t½ and test/reference (T/R) ratio for test product, ZEN 1.5, versus reference products, ASH 5 and ASH 10, were used for statistical comparisons. RESULTS: Subjects in the ZEN 1.5 group showed significantly (P < 0.05) higher total withanolides concentration in plasma at all post-dose time points except 12.00 and 24.00 h compared to ASH 5. In addition, subjects in Ashwagandha ZEN 1.5 group showed significantly higher (P < 0.05) total withanolides concentration in plasma at 0.25, 1.00, 2.00, 3.0, and 4.00 h compared to ASH 10. Further, ZEN 1.5 showed significantly higher bioavailability for total withanolides compared to ASH 5 and ASH 10 with significantly higher (P < 0.05) Cmax and AUC0-t parameters, T/R ratio, and 90% CI. ZEN 1.5 at 125-mg dose showed 2.1-fold higher bioavailability compared to ASH 5 at 600 mg, and 1.3-fold higher bioavailability compared to ASH 10 at 500 mg. ZEN 1.5 was well tolerated during the study period. CONCLUSION: A low dose of 125 mg of ZEN 1.5 showed greater total withanolides bioavailability compared to reference products. The Cmax and AUC parameters were significantly hig

BackgroundThe global medicine market is projected to reach US$417 billion by 2033, reflecting rising demand for natural healthcare alternatives. Ashwagandha (Withania somnifera) is widely used in Ayurvedic medicine for stress management, but evidence supporting its efficacy remains inconsistent.AimThis systematic review and meta-analysis evaluated Ashwagandha's impact on cortisol levels (a biological stress marker) and perceived stress via Perceived Stress Scale (PSS) scores across randomized controlled trials (RCTs).MethodPRISMA guidelines were followed. Four databases (PubMed, CINAHL, Google Scholar, and Scopus) were searched for studies from January 2012 to February 2024, yielding seven studies on cortisol and six on perceived stress (n = 488 participants). Inclusion criteria were RCTs longer than or equal to two weeks, oral doses ≥250 mg/day, and reporting cortisol and PSS outcomes. The Cochrane Risk of Bias 2 tool was used to assess the risk of bias.ResultsThere was a statistically significant reduction in cortisol levels (-1.16 µg/dL, 95% CI: -1.64 to -0.69, P < 0.001). No significant impact was observed on perceived stress (SMD = -0.355, 95% CI: -1.188 to 0.47; P = 0.40). Heterogeneity was moderate (I2 = 50.9%). However, no statistically significant impact was observed on perceived stress (SMD = -0.355, 95% CI: -1.188 to 0.47; P-value = 0.40). The heterogeneity among studies was moderate (I2 = 50.9%). Risk of bias was generally moderate; most studies reported adequate randomization, but some lacked allocation concealment. No publication bias was detected.ConclusionFindings support Ashwagandha's role in lowering cortisol, but gaps remain regarding long-term safety, dosing, and effectiveness across diverse populations. The disconnect between cortisol and PSS outcomes highlights the need for longer treatment duration and broader demographic inclusion. Longitudinal research is recommended to validate Ashwagandha as a holistic stress management tool.

Background: A nutritional supplement based on medicinal plants (saffron and ashwagandha), tryptophan, and vitamin B6 could contribute to alleviating/improving mood and associated disorders. The aim of this study was to evaluate the potential benefits of this combination supplement. During the study period, participants underwent a period of forced home confinement due to the COVID-19 pandemic, which represented an unexpected impact factor. Methods: This open-label prospective trial enrolled a cohort of female employees who reported mild to moderate anxiety. The primary objective was to evaluate changes in the level of anxiety using the adapted Hamilton Anxiety Rating Scale (HARS) after 12 weeks of regular supplementation with Safromotive (two tablets daily, for 12 weeks). The secondary objectives were to evaluate health-related quality of life (HRQoL) and tolerability. Results: In total, 46 women with a mean age of 45.0 (6.5) years were included. A statistically significant improvement in HARS was observed, with a 7.5-unit decrease from baseline to 12 weeks (p < 0.0001) and from 4 to 12 weeks of supplement intake (p=0.0058). However, no significant changes were found during the lockdown period (between weeks 8 and 12 of the study). No relationship was found between women's sociodemographic characteristics and the HARS total score. A significant reduction in the HRQoL questionnaire score of 1.2 units was observed between baselines and 12 weeks of treatment (p=0.0273). At the end of the study, 78.6% of the women reported consistency the supplement intake during the study course. Conclusion: This nutritional supplement composed of saffron, ashwagandha, tryptophan, and vitamin B6 appears to improve anxiety and HRQoL, but confinement could have impacted the evolution of the outcome.

INTRODUCTION: Allergic rhinitis (AR) is an IgE-mediated reaction to inhaled allergens, and is a prominent health concern affecting approximately 400 million people worldwide. A comprehensive understanding of AR's pathophysiology is imperative for developing novel therapies, especially considering its frequent co-morbidity with asthma and conjunctivitis. The escalating prevalence of AR is correlated with increased urbanization and environmental pollutants, recognized as prominent contributing factors. Dysregulation in immune networks, Th1/Th2 cytokine imbalance, activation of mast cells and eosinophils are implicated in AR progression. Classic AR symptoms include nasal congestion, nasal itching, rhinorrhea, and sneezing which significantly impact the quality of life, social interactions, and workplace productivity. METHODS: This randomized, double-blind, placebo-controlled, three-arm, three-sequence study was aimed to assess the efficacy of supplementation of a co-delivery form of turmeric extract with ashwagandha extract (CQAB) in comparison with a bioavailable curcumin (CGM) and placebo in alleviating AR symptoms and enhancing the quality of life in individuals with mild AR. Participants received either placebo, CGM, or CQAB twice/day for 28 days, and subjective measures were recorded at the baseline and at the end of study. RESULTS: CQAB supplementation demonstrated a significant (P < 0.05) improvement in Total Nasal Symptom Score (TNSS) compared to placebo and CGM. Furthermore, CQAB administration resulted in enhanced sleep quality (P < 0.05) as evaluated by the BIS questionnaire, heightened energy levels, and decreased fatigue and overall mood disturbance (POMS-SF) compared to both placebo and CGM. CONCLUSION: The results suggests that CQAB has the potential to be used as a dietary supplement in alleviating AR discomforts.

Update of Res Sq. 2024 Jan 12:rs.3.rs-3787917. doi: 10.21203/rs.3.rs-3787917/v1. Sub-optimal response in schizophrenia is frequent, warranting augmentation strategies over treatment-as-usual (TAU). We assessed nutraceuticals/phytoceutical augmentation strategies via network meta-analysis. Randomized controlled trials in schizophrenia/schizoaffective disorder were identified via the following databases: PubMed, MEDLINE, EMBASE, Scopus, PsycINFO, CENTRAL, and ClinicalTrials.gov. Change (Standardized Mean Difference = SMD) in total symptomatology and acceptability (Risk Ratio = RR) were co-primary outcomes. Secondary outcomes were positive, negative, cognitive, and depressive symptom changes, general psychopathology, tolerability, and response rates. We conducted subset analyses by disease phase and sensitivity analyses by risk of bias and assessed global/local inconsistency, publication bias, risk of bias, and confidence in the evidence. The systematic review included 49 records documenting 50 studies (n = 2384) documenting 22 interventions. Citicoline (SMD =-1.05,95%CI = -1.85; -0.24), L-lysine (SMD = -1.04,95%CI = -1.84; -0.25), N-acetylcysteine (SMD = -0.87, 95%CI = -1.27; -0.47) and sarcosine (SMD = -0.5,95%CI = -0.87-0.13) outperformed placebo for total symptomatology. High heterogeneity (tau2 = 0.10, I2 = 55.9%) and global inconsistency (Q = 40.79, df = 18, p = 0.002) emerged without publication bias (Egger's test, p = 0.42). Sarcosine improved negative symptoms (SMD = -0.65, 95%CI = -1.10; -0.19). N-acetylcysteine improved negative symptoms (SMD = -0.90, 95%CI = -1.42; -0.39)/general psychopathology (SMD = -0.76, 95%CI = -1.39; -0.13). No compound improved total symptomatology within acute phase studies (k = 7, n = 422). Sarcosine (SMD = -1.26,95%CI = -1.91; -0.60), citicoline (SMD = -1.05,95%CI = -1.65;-0.44), and N-acetylcysteine (SMD = -0.55,95%CI = -0.92,-0.19) outperformed placebo augmentation in clinically stable participants. Sensitivity analyses removing high-risk-of-bias studies confirmed overall findings in all phases and clinically stable samples. In contrast, the acute phase analysis restricted to low risk-of-bias studies showed a superior effe

BACKGROUND: Ashwagandha has been reported to reduce stress and attenuate cognitive decline associated with inflammation and neurodegeneration in clinical populations. However, the effects as a potential nootropic nutrient in younger populations are unclear. This study examined the effects of liposomal ashwagandha supplementation on cognitive function, mood, and markers of health and safety in healthy young men and women. METHODS: 59 men and women (22.7 ± 7 yrs., 74.9 ± 16 kg, 26.2 ± 5 BMI) fasted for 12 h, donated a fasting blood sample, and were administered the COMPASS cognitive function test battery (Word Recall, Word recognition, Choice Reaction Time Task, Picture Recognition, Digit Vigilance Task, Corsi Block test, Stroop test) and profile of mood states (POMS). In a randomized and double-blind manner, participants were administered 225 mg of a placebo (Gum Arabic) or ashwagandha (Withania somnifera) root and leaf extract coated with a liposomal covering. After 60-min, participants repeated cognitive assessments. Participants continued supplementation (225 mg/d) for 30 days and then returned to the lab to repeat the experiment. Data were analyzed using a general linear model (GLM) univariate analysis with repeated measures and pairwise comparisons of mean changes from baseline with 95% confidence intervals (CI). RESULTS: Ashwagandha supplementation improved acute and/or 30-day measures of Word Recall (correct and recalled attempts), Choice Reaction Time (targets identified), Picture Recognition ("yes" correct responses, correct and overall reaction time), Digit Vigilance (correct reaction time), Stroop Color-Word (congruent words identified, reaction time), and POMS (tension and fatigue) from baseline more consistently with several differences observed between groups. CONCLUSION: Results support contentions that ashwagandha supplementation (225 mg) may improve some measures of memory, attention, vigilance, attention, and executive function while decreasing perceptions of tension and fatigue in younger healthy individuals.

BACKGROUND: Back pain is a common health problem that affects both workers and older people, reducing their quality of life. The primary objective was to assess the effect of dietary supplementation with plant extracts of rosemary, ashwagandha, and sesame consumed for 12 weeks on the intensity of back pain. METHODS: A single-center randomized double-blind study with three parallel arms depending on the product consumed. The duration of treatment was 12 weeks. The investigational product, Berelief®, contained a blend of three polyphenolic standardized extracts: rosemary (Rosmarinus officinalis L.), ashwagandha (Withania somnifera L.), and sesame (Sesamum indicum L.) seed. Two doses were tested: low dose (400 mg) and high dose (800 mg). There were 42 subjects in the placebo group, 39 in the low dose and 42 in the high dose groups. Study variables included back pain intensity [VAS score, Patient-Reported Outcomes Measurement Information System (PROMIS-29), and Cornell Musculoskeletal Discomfort Questionnaire; functionality Roland-Morris Disability (RMD) questionnaire]; quality of life (QoL) [36-item Short Form Survey (SF-36), the Beck Depression Inventory-II (BDI-II), the State-Trait Anxiety Inventory (STAI), and the Perceived Stress Scale (PSS)]; sleep quality [accelerometer and Pittsburgh Sleep Quality Index (PSQI)]. RESULTS: The improvement in back pain recorded by the visual analogue scale (VAS) at the study visits after the beginning of treatment, as well as on a weekly basis recorded in the diary card was significantly higher in the intervention group than in the placebo group (p < 0.044 dose-low; p < 0.005 dose-high). Significant differences in pain intensity of the PROMIS-29 (p = 0.002) and upper back pain in the Cornell questionnaire (p = 0.011) in favour of the investigational product were found. Furthermore, benefits in improving health-related quality of life, mood and sleep quality were also detected. CONCLUSION: Dietary supplementation for 12 weeks of a blend of polyphenolic standardized extracts of rosemary, ashwagandha, and sesame was effective in reducing the intensity of pain in subjects with chronic myofascial cervical and back pain.
