Effect of Ashwagandha Root Extract on Stress, Anxiety, and Sleep Quality in Adults Experiencing Minority Stress

Sexual and gender minority adults often experience elevated levels of chronic stress due to stigma, discrimination, and social adversity, commonly referred to as minority stress. This persistent stress is associated with increased anxiety, mood disturbances, impaired sleep quality, and reduced quality of life. There is a need for safe, non-pharmacological interventions that can support mental well-being in this population. This randomized, double-blind, placebo-controlled study is designed to evaluate the efficacy and safety of Ashwagandha (Withania somnifera) root extract in reducing stress and improving anxiety and sleep quality in adults experiencing minority stress. A total of 80 adults aged 18 to 45 years who self-identify as sexual or gender minorities and report moderate to high perceived stress will be enrolled. Participants will be randomly assigned to receive either Ashwagandha root extract (300 mg capsules taken twice daily) or an identical placebo for 8 weeks. Efficacy will be assessed using validated psychological and quality-of-life questionnaires, including the Perceived Stress Scale, Depression Anxiety Stress Scale, Pittsburgh Sleep Quality Index, and other mood and minority stress measures. Salivary cortisol will be measured as a biological marker of stress. Safety will be evaluated through monitoring of adverse events throughout the study.

Efficacy and Safety of Shatavari Root Extract for Premenstrual Syndrome in Women

Premenstrual syndrome (PMS) is a common condition that affects women of reproductive age and is associated with emotional, physical, and behavioral symptoms such as mood swings, irritability, stress, sleep problems, fatigue, and abdominal discomfort. These symptoms typically occur during the days leading up to menstruation and may interfere with daily activities and overall quality of life. This study is designed to evaluate the efficacy and safety of Shatavari (Asparagus racemosus) root extract compared with placebo in women with mild to moderate PMS. Eligible participants will be randomly assigned to receive either Shatavari root extract (300 mg) or an identical placebo capsule once daily for 12 weeks. The study will assess changes in PMS symptoms, stress levels, sleep quality, and quality of life using validated questionnaires, along with measurements of salivary cortisol. Safety will be evaluated through clinical laboratory tests and monitoring of adverse events throughout the study.

An 8-Week Study Evaluating Gut and Digestive Health After Use of a Dietary Supplement System

This clinical research study is being conducted to evaluate gut and digestive health before and after the use of a dietary supplement system over an eight-week period. Gut and digestive health play an important role in overall health, including digestion, nutrient absorption, immune function, and metabolic balance. Changes in gut microbiota, inflammation, and intestinal barrier function may contribute to digestive symptoms such as bloating, discomfort, altered bowel habits, and reduced well-being. In this study, adult men and women with self-reported gastrointestinal symptoms will consume a dietary supplement system daily for eight weeks. The study will measure changes in gut and digestive health using objective stool-based laboratory biomarkers and validated symptom questionnaires. Stool samples will be collected at baseline and at the end of the study to evaluate markers related to microbial diversity, inflammation, immune activity, digestive function, and intestinal barrier integrity. Participants will also complete questionnaires throughout the study to assess gastrointestinal symptoms and subjective digestive health and well-being. The study will also monitor the safety and tolerability of the dietary supplement system during the study period.

A Study of a Dietary Supplement on Serum Biomarkers in Children

This is a pilot clinical study designed to evaluate the effects of a dietary supplement on selected blood-based nutritional biomarkers in healthy children aged 4 to 15 years. Approximately 24 children will be screened and enrolled to account for potential dropouts, with a target of 20 participants completing the study. Eligible participants will attend a screening and baseline visit, followed by daily intake of the study supplement for 4 weeks. After the supplementation period, participants will return to the clinic for an end-of-study visit. Blood samples will be collected at baseline and after 4 weeks to measure nutritional biomarkers, including vitamin D, vitamin B12, folate, omega-3 fatty acids, and standard blood count parameters. Additional assessments include height, weight, body mass index (BMI), and a socioeconomic questionnaire. Throughout the study, participants or their caregivers will record daily supplement intake, any medications taken, and any adverse events in a study diary. The results of this pilot study will provide preliminary data on the effects of the dietary supplement on serum biomarkers in children.

Effects of Sabroxy® Supplementation on Insulin Resistance and Cognitive Function in Adults With Mild Cognitive Impairment and Insulin Resistance

This randomized, double-blind, placebo-controlled, 8-week clinical trial is designed to evaluate the effects of Sabroxy®, a standardized extract of Oroxylum indicum bark, on insulin resistance and cognitive function in adults with mild cognitive impairment and insulin resistance. A total of 120 participants (men and women, aged 40-80 years) who are non-smokers, with fasting glucose levels between 100-135 mg/dL, HOMA-IR value ≥ 2.0 to \< 4.0, and a Montreal Cognitive Assessment (MoCA) score below 26, will be enrolled. Eligible participants will be randomized (1:1) to receive either Sabroxy® (250 mg with 5 mg BioPerine®) or placebo, administered orally once daily for 8 weeks. The primary endpoint is the change in insulin resistance from baseline to Week 8, assessed using the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR). The secondary endpoints include changes in: Cognitive performance, assessed using the Immediate Word Recall, Numeric Working Memory, Cognitive Failures Questionnaire (CFQ), and Montreal Cognitive Assessment (MoCA). Biomarkers of metabolic and neuronal function, including Brain-Derived Neurotrophic Factor (BDNF), high-sensitivity C-reactive protein (hs-CRP), fasting insulin, fasting glucose, and phosphorylated tau/amyloid beta (p-Tau/Aβ) ratio. Safety will be assessed through adverse event monitoring, vital signs, and routine clinical laboratory tests. The study will be conducted at a single site, San Francisco Research Institute (USA), in compliance with the Declaration of Helsinki, ICH-GCP guidelines, and 21 CFR Part 312 (where applicable). This study seeks to generate clinical evidence supporting the potential of Sabroxy® supplementation to improve glucose tolerance, reduce inflammation, and enhance cognitive function in individuals with early metabolic and neurocognitive dysfunctions.

Effects of KSM-66 Ashwagandha® (300 mg) on Skin and Hair Health in Healthy Men and Women"

Hair and skin play major roles in protecting the body, and maintaining their health is essential. Poor hair and skin health have become increasingly common due to the stress associated with modern lifestyles. Effective and time-efficient treatments for hair and skin health remain limited. Although hair loss, baldness, and skin issues are not life-threatening, managing these conditions is important because of the psychological and social complications-such as anxiety and depression-they can cause. There is an unmet need for therapies that provide safe and long-term improvements in hair and skin health. Many individuals seek Complementary and Alternative Medicine (CAM) to identify natural and effective options for these conditions. Adaptogens such as Ashwagandha (Withania somnifera) have long been studied for their potential to reduce stress and modulate cortisol levels in the body. Reducing stress may help prevent inflammation, a common contributor to hair shedding and loss. Ashwagandha also contains antioxidants and amino acids that may strengthen the hair and minimize breakage. Traditionally, Ashwagandha has been recognized for its multiple health benefits, including support for hair and skin wellness. However, there remains limited scientific evidence to substantiate these traditional claims, underscoring the need for controlled clinical evaluation.
