Upper respiratory symptoms are often treated with over the counter drugs, antibiotics, and antiviral medications. Due to concerns about safety and efficacy, there is a demand for an alternative solution. Black elderberry (Sambucus nigra) has been used to treat cold and flu symptoms, but there are no large-scale studies or meta-analyses. This meta-analysis quantifies the effects of elderberry supplementation and evaluates moderators including vaccination status and the underlying pathology. This analysis included a total of 180 participants and evaluates moderators such as vaccination status and cause of the upper respiratory symptoms. Supplementation with elderberry was found to substantially reduce upper respiratory symptoms. The quantitative synthesis of the effects yielded a large mean effect size. These findings present an alternative to antibiotic misuse for upper respiratory symptoms due to viral infections, and a potentially safer alternative to prescription drugs for routine cases of the common cold and influenza.

Despite data showing that nutritional interventions high in antioxidant/anti-inflammatory properties (anthocyanin-rich foods, such as blueberries/elderberries) may decrease risk of memory loss and cognitive decline, evidence for such effects in mild cognitive impairment (MCI) is limited. This study examined preliminary effects of American elderberry (Sambucus nigra subsp. canadensis) juice on cognition and inflammatory markers in patients with MCI. In a randomized, double-blind, placebo-controlled trial, patients with MCI (n = 24, Mage = 76.33 ± 6.95) received American elderberry (n = 11) or placebo (n = 13) juice (5 mL orally 3 times a day) for 6 months. At baseline, 3 months, and 6 months, patients completed tasks measuring global cognition, verbal memory, language, visuospatial cognitive flexibility/problem solving, and memory. A subsample (n = 12, 7 elderberry/5 placebo) provided blood samples to measure serum inflammatory markers. Multilevel models examined effects of the condition (elderberry/placebo), time (baseline/3 months/6 months), and condition by time interactions on cognition/inflammation outcomes. Attrition rates for elderberry (18%) and placebo (15%) conditions were fairly low. The dosage compliance (elderberry-97%; placebo-97%) and completion of cognitive (elderberry-88%; placebo-87%) and blood-based (elderberry-100%; placebo-100%) assessments was high. Elderberry (not placebo) trended (p = 0.09) towards faster visuospatial problem solving performance from baseline to 6 months. For the elderberry condition, there were significant or significantly trending decreases over time across several markers of low-grade peripheral inflammation, including vasorin, prenylcysteine oxidase 1, and complement Factor D. Only one inflammatory marker showed an increase over time (alpha-2-macroglobin). In contrast, for the placebo, several inflammatory marker levels increased across time (L-lactate dehydrogenase B chain, complement Factor D), with one showing deceased levels over time (L-lactate dehydrogenase A chain). Daily elderberry juice consumption in patients with MCI is feasible and well tolerated and may provide some benefit to visuospatial cognitive flexib

Background/Objectives: Seasonal waves of respiratory viruses-including SARS-CoV-2, influenza A virus (IAV), and respiratory syncytial virus (RSV)-continue to pose a global health burden and highlight the need for antiviral agents that are effective, safe, broadly active, affordable, and widely accessible. Current interventions are limited by the need for their early administration, the risk of resistance, their costs, and the restricted availability in large parts of the world. For certain natural products, such as European black elderberry (Sambucus nigra L.) fruit extract (ElderCraft®; EC) and the seaweed-derived sulfated polymer iota-carrageenan (IC), antiviral activities against respiratory viruses, particularly IAV and SARS-CoV-2, have previously been shown. Here, we assessed the antiviral activity of IC and an anthocyanin-standardized EC extract against SARS-CoV-2, IAV, and RSV, either as monotherapy or in multiple-dose combinations. Methods: MDCKII cells were infected with IAVPR8, human Calu-3 lung epithelial cells with the SARS-CoV-2 Omicron variant, and HEp-2 cells with RSV (A2 strain). Inhibitors were administered either by pre-incubation of cell-free virions prior to infection or, in separate time-of-addition experiments, during or post-infection. Viral replication was quantified by qRT-PCR or intracellular immunostaining. Cytotoxicity was evaluated using a neutral red uptake assay. Results: Most intriguingly, both EC and IC are able to neutralize virions derived from SARS-CoV-2, IAV, or RSV extracellularly in a dose-dependent manner. Notably, EC and IC alone exhibited strong anti-RSV activity, which was not reported previously. Most importantly, combined treatment with IC and EC caused a pronounced synergistic antiviral effect against the tested viruses, as confirmed by the Bliss independence model, without any detectable impact on cell viability. Finally, solutions prepared from matrix-standardized mono- or combi-lozenges, containing IC and/or EC in high or low doses, reproduced the antiviral and synergistic combination effects observed with the pure compounds. Conclusions: In summary, these findings support further development of EC and IC as a top

BACKGROUND/OBJECTIVES: The persistent threat of emerging respiratory RNA viruses like SARS-CoV-2 and Influenza A virus (IAV) necessitates the continuous development of effective, safe, broadly acting, and generally accessible antiviral agents. Current treatments often face limitations such as early administration requirements, resistance development, and limited global access. Natural products, like European black elderberry (Sambucus nigra L.; S. nigra) fruit extract and quinine, have been used historically against viral infections. In this study, we investigated the antiviral efficacy of a standardized black elderberry fruit extract containing 3.2% anthocyanins (EC 3.2) and, as a second natural antiviral product, quinine, against IAV and SARS-CoV-2 in vitro. METHODS: Madin-Darby Canine Kidney II (MDCKII) cells were infected with IAV PR-8, while human Calu-3 lung epithelial cells were infected with Wuhan-type SARS-CoV-2. Cells were treated with varying concentrations of EC 3.2 and quinine either as mono- or combinational therapy. Viral replication was assessed using quantitative RT-PCR, and cell viability was evaluated using WST-1 assays. RESULTS: Our results demonstrate, for the first time, that both EC 3.2 and quinine individually inhibited IAV replication in a dose-dependent manner, with IC50 values of approximately 1:400 for EC 3.2 and 250 nM for quinine. Most importantly, the combinational treatment exhibited a strong synergistic antiviral effect, as confirmed by the Bliss independence model (synergy scores of 14.7 for IAV, and 27.8 for SARS-CoV-2), without affecting cell viability. CONCLUSIONS: These findings suggest that the combined use of black elderberry extract and quinine might serve as an effective antiviral strategy against IAV and SARS-CoV-2, particularly since the synergistic effect allows for lower doses of each product while retaining therapeutic efficacy. In summary, this combinational in vitro approach, when expanded to other respiratory RNA viruses and confirmed in clinical studies, has the potential to open a promising avenue for pandemic preparedness.

A field experiment and two oxidation experiments in the laboratory were carried out. The content of the major anthocyanins, cyanidin-3-glucoside (Cy-3-G) and cyanidin-3-sambubioside (Cy-3-Sa), in the fresh fruits from the 13 cultivars were from 361 to 1266 and from 269 to 656 mg/100 g, respectively. The two minor anthocyanins, cyanidin-3-sambubioside-5-glucoside (Cy-3-Sa-5-G) and cyanidin-3.5-diglucoside (Cy-3.5-dG), occurred in concentrations between 5 and 47 mg/100 g. The content of ascorbic acid and quercetin in the fresh fruits of the cultivars varied from 6 to 25, and from 29 to 60 mg/100 g, respectively. Purging of the elderberry juice with N2 and/or addition of ascorbic acid reduced the oxidative degradation rate of the two major anthocyanins and quercetin. Ascorbic acid protected the anthocyanins, but not quercetin from oxidative degradation. Mixing of fruits with air during processing and even a low content of oxygen in the juice before tapping must be avoided by appropriate steps during processing. Improvement of the nutritional value of the elderberry juice and increased protection of anthocyanins against oxidative degradation may potentially be obtained by selection of cultivars with a high content of ascorbic acid.

Background: Respiratory tract infections (RTIs) are common in children and represent one of the main reasons for pediatric consultations. Although generally benign, pediatric RTIs can lead to medical complications and significant socioeconomic burden. The objective of this trial was to evaluate the efficacy of a food supplement intended to support the immune system in reducing the rate and severity of pediatric RTIs. Methods: A randomized, double-blind, placebo-controlled, parallel-group clinical trial was conducted to assess the efficacy and safety of a food supplement based on vitamins, minerals, herbal extracts, and Lactobacillus rhamnosus CRL1505 (Pegaso® Immuno Junior). A daily dose was administered for approximately 60 days within a three-month period to children aged 3-10 years with at least four RTI episodes in the previous year. RTI frequency, illness days, days with fever, cough, and rhinitis, and antipyretic and antibiotic use per episode were recorded over four months. Results: A total of 110 children completed the study. Compared with the placebo, the active supplement significantly reduced the mean number of RTI episodes per child (2.41 ± 0.84 vs. 4.13 ± 1.66; RR = 0.745, 95% CI 0.583-0.953) as well as the number of illness days, days with fever, cough, and rhinitis, and days with antipyretic or antibiotic use. The supplement was well-tolerated. Conclusions: The patented supplementation based on vitamins, minerals, herbal extracts, and Lactobacillus rhamnosus CRL1505 (Pegaso® Immuno Junior), taken over a three-month period, may reduce the frequency and severity of RTIs in children aged 3-10 years.

BACKGROUND: Elderberry (Sambucus nigra L.) has been traditionally implemented in diverse preparations such as herbal teas, syrups or juices as remedies for respiratory, febrile and other health conditions. Phytochemical and chromatographic analyses of different organs mapped their metabolite profiles and allowed identification, and sometimes isolation, of their main bioactive compounds. AIM OF THE STUDY: Inspired by the rich and effective literature of S. nigra, this review article aims to summarize and highlight its reported biological (traditional and research-based) and chemical profiles. METHODS: The Keywords used in the search included biological activities, pharmacological reports, phytochemistry, isolated compounds, taxonomy, botanical data, single or combination; traditional, traditionally, ethnopharmacology, folk uses, toxicity, LD50, interactions, side effects, clinical studies, elderberry, elder, Sambucus nigra. Using different bibliographic databases, Google Scholar, PubMed, Web of Science, Springer Link, and Science Direct with no specific limits. RESULTS: In this context, elderberry is deemed a rich source for a myriad of bioactive compounds, mainly phenolics, and was proven to exhibit a variety of health benefits, including antioxidant, anti-inflammatory, anticancer, anti-influenza, antimicrobial, antidiabetic, cardioprotective, and neuroprotective properties. This review also covers different analysis approaches applied for S. nigra characterization in addition to literature studies attempted to optimize its extract(s) preparation process in terms of different extraction solvents, temperatures or methodologies to enrich prepared extracts in beneficial and bioactive metabolites. CONCLUSION: Overall, elderberry holds substantial potential as a rich dietary source of bioactive metabolites. Future research into its application in functional foods and nutraceuticals may provide innovative strategies for the prevention and management of various chronic diseases.

BACKGROUND/OBJECTIVES: Dry eye disease (DED) significantly impairs quality of life, affecting physical, social, and psychological well-being, as well as reducing workplace productivity. While lutein and zeaxanthin supplements have been shown to improve ocular health, existing research often overlooks the efficacy of lower dosages and shorter durations of supplementation. This study investigated the effects of combined supplementation with lutein, zeaxanthin, and elderberries in 110 voluntary participants through a randomized controlled trial. METHODS: Participants took 6 mg of lutein and 1 mg of zeaxanthin, along with 100 mg elderberry extract once daily for a duration of 20 days. Ocular health was assessed using the Ocular Surface Disease Index (OSDI), while immune status was evaluated with the Immune Status Questionnaire (ISQ). RESULTS: Results showed that combined supplementation significantly (p < 0.05) reduced the OSDI scores in the intervention group from 38.15 ± 11.14 to 18.26 ± 5.57, reflecting a 52.2% reduction. A similar trend was observed with the Visual Analog Scale (VAS), indicating significant (p < 0.05) improvement from 5.31 ± 1.62 to 6.73 ± 1.74, equivalent to a 26.7% improvement. Although the intervention group showed a 15.9% improvement in ISQ scores by the study's end, this was not significantly different from the placebo group, suggesting that higher dosages or longer durations may be needed to observe a meaningful effect. Additionally, findings from the Food Frequency Questionnaire revealed that the average dietary intake of lutein and zeaxanthin among participants was only 663.49 µg, equating to just 5.5% of the suggested optimal daily intake. This low consumption is concerning, as it is inversely correlated with the risk of ocular diseases. CONCLUSIONS: Collectively, these findings support the use of combined supplementation as an adjuvant approach to improving ocular health.

The irregular lifestyle of airline crew members, wide/adverse job-related exposures, and the impact of temporary hypoxia on gut microbiota well-being have increased concern about the daily recommended dose of certain nutrients among flight crew. The aim of this study was to determine if daily consumption of a SYNBIO® probiotics-elderberry extract supplement (ACTIVE) may contribute to the well-being of flight attendants. Forty healthy crew members enrolled in a double-blind, randomized, placebo-controlled study consumed one ACTIVE capsule/day or placebo for 30 days. Bowel well-being, health-related quality of life, and gastrointestinal tolerance were assessed by validated questionnaires. Saliva and fecal samples were analyzed to determine secretory immunoglobulin-A (sIgA) levels and to characterize gut microbiota composition, respectively. ACTIVE subjects presented a physiological improvement and a statistically significant higher Psychological General Well-Being Index (PGWBI) global score compared to PLACEBO subjects. The ACTIVE subjects showed significantly increased levels of lactobacilli and bifidobacteria compared to the PLACEBO group, while a significant increase in lactobacilli and a significant reduction in Enterobacteriaceae were registered when compared with the beginning of supplementation, confirming the persistence of probiotics in the gastrointestinal tract and the direct antagonism and competitive exclusion effects. Additionally, sIgA levels were significantly higher in the ACTIVE group compared to the baseline and to the PLACEBO group at the end of supplementation. The ACTIVE supplementation might be beneficial to airline crew members, improving their physiological state, their immune defenses, and the strength and efficiency of their gastrointestinal tract when responding to stressful conditions.

Elderly people are at high risk of suffering from infection and being affected by severe forms of disease because their immunosystem suffers from aging. The alteration of normal immune functions causes the increase of pro-inflammatory cytokines which can expose these people to increased risk of developing pathologies as cancer, diabetes, and/or arthritis. Some supplements could be helpful for restoring normal immune functions. We conducted a case-control study to evaluate the efficacy of a supplement containing Sambucus nigra, zinc, tyndallized Lactobacillus acidophilus (HA122), arabinogalactans, vitamin D, vitamin E, and vitamin C to improve the inflammatory levels (IL-6 and CRP) and to modulate the lymphocytes growth. Additionally, we analyzed wellness by self-questionnaire. This study had two control group: a young group and an elderly one. Our study showed that treating elderly patients with the supplement for 30 days improved IL-6, CRP, and lymphocytes levels; the result was independent from the dosage of the supplements used. Elderly patients, despite the improvement, were not able to reach the same conditions of young patients; however, most of the patients (>70%) claimed to “feel better” after the use of the supplement. The use of this supplement should be considered at a low dosage for a prolonged period to reduce inflammation and modulate immune senescence in patients over 60 years old.

BACKGROUND: Respiratory infections (RI) significantly burden society, mainly when there are recurrent respiratory infections (RRI). Thus, there is a need to prevent RI in clinical practice. In this regard, the modulation of the immune system and resolution of the inflammatory cascade could represent an ideal way to prevent RI. Stimunex® gocce, a multicomponent food supplement, contains Sambucus nigra extract, β-glucan, Zinc, and Vitamin D3. This study investigated its ability to prevent RRI in children using a real-world setting: the pediatric primary care. MATERIALS AND METHODS: Two hundred and ninety-eight children with RRI were enrolled in the current study. The food supplement was randomly prescribed to 160 children with RRI daily for 4 months (Active group); the remaining 138 children with RRI were treated only with standard therapy for RI (Control group). The number and duration of RI, parental perception of symptom severity and treatment efficacy, use of medications, and school and working absence were evaluated. RESULTS: Children treated with Stimunex® gocce had significantly less RI than the Control group, both concerning upper and lower RI (p˂0.001 and 0.003, respectively) during the follow-up period. Moreover, children in the Active group experienced shorter RI duration during the treatment and follow-up phases (p˂0.001 for both). In addition, parents of treated children perceived less severe symptoms and better treatment efficacy during the first and follow-up phases (p˂0.001 for all). The food supplement was well tolerated and there was no adverse event. CONCLUSIONS: The current real-world study demonstrated that Stimunex® gocce supplementation in children with RRI might safely prevent RI episodes and reduce RI duration. These outcomes should be highlighted as obtained during the COVID-19 pandemic era, characterized by a dramatic reduction of RI.

Recently, the outbreak of severe acute respiratory syndrome cornoavirus-2 (SARS-CoV-2), causing coronavirus disease 2019 (COVID-19), has become a great perturbation all around the globe and has many devastating effects on every aspect of life. Apart from the oxygen therapy and extracorporeal membrane oxygenation, Remdesivir and Dexamethasone have been proven to be efficacious against COVID-19, along with various vaccine candidates and monoclonal antibody cocktail therapy for Regeneron. All of these are currently at different stages of clinical trials. People with weak immunity are more prone to a severe infection of SARS-CoV-2. Therefore, early and judicious nutritional supplementation along with pharmacological treatment and clinician collaborations are critical in restituting the current situation. Nutritional supplements help in acquiring strong immunity to prevent the progression of disease any further. Vitamin C, vitamin D, selenium, zinc and many other nutritional and dietary supplements inhibit the production of inflammatory cytokines during a viral infection and prevents several unwanted symptoms of infection. Many dietary components like citrus fruits, black elderberry, ginger, and probiotics have the ability to attack viral replication. These supplements can also tame the overriding immune system during coronavirus infection. Keeping in view these facts, nutritional and dietary supplements can be used along with other management modalities. These nutritional and dietary supplements are potential candidates to curb the convulsive unfolding of novel COVID-19, in combination with other standard treatment protocols. In this review, various search engines were used to exploit available literature in order to provide a comprehensive review on nutritional and dietary supplements with respect to the viral infections. It will also provide a brief overview on some of the clinical trials that are in progress to assess the role of nutritional supplements, either alone or in combination with other pharmacological drugs, in fight against COVID-19.

Oral supplements (OS) support the immune system in fighting upper airways infection. This study aimed to analyze the effect of Difensil Immuno (DI) on the recurrence of tonsillitis and fever in children. A multicentric randomized clinical trial was conducted. One-hundred and twenty children with chronic tonsillitis were randomly assigned to group A, B or control. Patients in group A were treated with 10 mL of DI for 90 consecutive days, patients in group B underwent treatment with 15 mL of DI for 45 consecutive days. The following data were collected at baseline (T0), T1 and T2: tonsillitis and fever episodes, tonsillar volume, blood test results. One-way ANOVA was used to analyze within and between variances. Patients in group A and B statistically improved their clinical parameters (episode of tonsillitis and fever, tonsillar volume) when compared to control group both at T1 and T2. However, T1 variances were more consistent in group A than in group B. All patients in the study groups improved their clinical outcomes. No statistically significant variances were observed in blood parameters both at T1 and T2. Our results suggest that children treated with DI had fewer episodes of tonsillitis and fever and a reduction in their tonsillar volume.

Intercontinental air travel can be stressful, especially for respiratory health. Elderberries have been used traditionally, and in some observational and clinical studies, as supportive agents against the common cold and influenza. This randomized, double-blind placebo-controlled clinical trial of 312 economy class passengers travelling from Australia to an overseas destination aimed to investigate if a standardised membrane filtered elderberry (Sambucus nigra L.) extract has beneficial effects on physical, especially respiratory, and mental health. Cold episodes, cold duration and symptoms were noted in a daily diary and assessed using the Jackson score. Participants also completed three surveys containing questions regarding upper respiratory symptoms (WURSS-21) and quality of life (SF-12) at baseline, just before travel and at 4-days after travel. Most cold episodes occurred in the placebo group (17 vs. 12), however the difference was not significant (p = 0.4). Placebo group participants had a significantly longer duration of cold episode days (117 vs. 57, p = 0.02) and the average symptom score over these days was also significantly higher (583 vs. 247, p = 0.05). These data suggest a significant reduction of cold duration and severity in air travelers. More research is warranted to confirm this effect and to evaluate elderberry's physical and mental health benefits.

Increased tissue status of the long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFA), eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) is associated with cardiovascular and cognitive benefits. Limited epidemiological and animal data suggest that flavonoids, and specifically anthocyanins, may increase EPA and DHA levels, potentially by increasing their synthesis from the shorter-chain n-3 PUFA, α-linolenic acid. Using complimentary cell, rodent and human studies we investigated the impact of anthocyanins and anthocyanin-rich foods/extracts on plasma and tissue EPA and DHA levels and on the expression of fatty acid desaturase 2 (FADS2), which represents the rate limiting enzymes in EPA and DHA synthesis. In experiment 1, rats were fed a standard diet containing either palm oil or rapeseed oil supplemented with pure anthocyanins for 8 weeks. Retrospective fatty acid analysis was conducted on plasma samples collected from a human randomized controlled trial where participants consumed an elderberry extract for 12 weeks (experiment 2). HepG2 cells were cultured with α-linolenic acid with or without select anthocyanins and their in vivo metabolites for 24 h and 48 h (experiment 3). The fatty acid composition of the cell membranes, plasma and liver tissues were analyzed by gas chromatography. Anthocyanins and anthocyanin-rich food intake had no significant impact on EPA or DHA status or FADS2 gene expression in any model system. These data indicate little impact of dietary anthocyanins on n-3 PUFA distribution and suggest that the increasingly recognized benefits of anthocyanins are unlikely to be the result of a beneficial impact on tissue fatty acid status.

SCOPE: Numerous studies feeding anthocyanin-rich foods report limited bioavailability of the parent anthocyanins. The present study explores the identity and concentration of the phenolic metabolites of anthocyanins in humans. METHODS AND RESULTS: Anthocyanin metabolites were quantified in samples collected from a previously conducted 12-wk elderberry intervention study in healthy post-menopausal women. Individual 1-, 2- and 3-h post-bolus urine samples and pooled plasma samples following acute (single bolus) and chronic (12-wk supplementation) anthocyanin consumption (500 mg/day) were analysed using HPLC-ESI-MS/MS. Twenty-eight anthocyanin metabolites were identified in urine and 21 in plasma (including sulfates of vanillic, protocatechuic and benzoic acid). Phenolic metabolites reached peak concentrations of 1237 nM in plasma, while anthocyanin conjugates only reached concentrations of 34 nM. Similarly, in urine, phenolic metabolites were detected at concentrations of 33,185 ± 2549 nM/mM creatinine, while anthocyanin conjugates reached concentrations of 548 ± 219 nM/mM creatinine. There was no evidence that chronic exposure had any impact on either the profile or quantity of metabolites recovered relative to acute exposure. CONCLUSION: An extensive range of phenolic metabolites of anthocyanin was identified following elderberry consumption in humans, including 11 novel metabolites, which were identified at much higher concentrations than their parent compounds. © 2013 WILEY-VCH Verlag GmbH & Co.

Comment in World J Gastroenterol. 2010 Oct 14;16(38):4880-2. doi: 10.3748/wjg.v16.i38.4880. This review focuses on the efficacy and safety of effective herbal medicines in the management of obesity in humans and animals. PubMed, Scopus, Google Scholar, Web of Science, and IranMedex databases were searched up to December 30, 2008. The search terms were "obesity" and ("herbal medicine" or "plant", "plant medicinal" or "medicine traditional") without narrowing or limiting search elements. All of the human and animal studies on the effects of herbs with the key outcome of change in anthropometric measures such as body weight and waist-hip circumference, body fat, amount of food intake, and appetite were included. In vitro studies, reviews, and letters to editors were excluded. Of the publications identified in the initial database, 915 results were identified and reviewed, and a total of 77 studies were included (19 human and 58 animal studies). Studies with Cissus quadrangularis (CQ), Sambucus nigra, Asparagus officinalis, Garcinia atroviridis, ephedra and caffeine, Slimax (extract of several plants including Zingiber officinale and Bofutsushosan) showed a significant decrease in body weight. In 41 animal studies, significant weight loss or inhibition of weight gain was found. No significant adverse effects or mortality were observed except in studies with supplements containing ephedra, caffeine and Bofutsushosan. In conclusion, compounds containing ephedra, CQ, ginseng, bitter melon, and zingiber were found to be effective in the management of obesity. Attention to these natural compounds would open a new approach for novel therapeutic and more effective agents.

The aim of the study was to obtain information on the content of co-active compounds of a food supplement recommended as a weight reduction diet and on its short-term effectiveness and safety as a starter for lifestyle change. Eighty participants completed the protocol. The Sambucus nigra L. berry juice enriched with flower extract and tablets containing berry powder and flower extract provided a total of 1 mg anthocyanins, 370 mg flavonol glycosides and 150 mg hydroxycinnamates per day; the Asparagus officinalis L. powder tablets provided 19 mg saponins per day. After the diet, the mean weight, blood pressure, physical and emotional well-being and the quality of life had significantly improved (ITT analysis). The effectiveness and tolerability of the regimen were rated as very good or good by most of the completers. It remains to be established if any particular compounds contribute to the efficacy of the diet.
