Organic Ashwaganda
Also known as: Ashwagandha, Indian ginseng, Winter cherry, Somnifera, Withania, Withania somnifera
Overview
Ashwagandha is an adaptogenic herb derived from the roots and leaves of the *Withania somnifera* plant, primarily found in India, Africa, and the Middle East. Traditionally used to enhance mental and physical health, it promotes stress reduction and overall well-being. As an adaptogen, Ashwagandha helps the body adapt to stressors by acting on the hypothalamic-pituitary-adrenal (HPA) axis and regulating neurotransmitter systems. The existing research on Ashwagandha is moderate to high-quality, indicating its effectiveness in reducing stress and anxiety, and enhancing physical performance. However, variability in study quality exists, with some small sample-size studies showing limitations. Available in forms like capsules, powders, and extracts, Ashwagandha caters to various dietary preferences and needs.
Benefits
Research indicates that Ashwagandha provides significant evidence-based benefits, particularly in reducing stress and anxiety levels. Systematic reviews report strong effect sizes, with an effect size of -1.55 for anxiety and -1.75 for stress (p = 0.005). It may also enhance physical performance, especially VO2max, with a meta-analysis indicating a mean difference of 3.00. Improvements in strength and power are highlighted in Bayesian analyses, demonstrating potential clinical significance. Athletes and trained individuals may experience amplified benefits from dosages of 330-1000 mg/day. Users often notice improvements in stress and anxiety within 8-12 weeks, with physical performance enhancements appearing over a similar timeframe.
How it works
Ashwagandha's primary mechanism involves modulation of the HPA axis, which regulates the body's stress response, alongside influencing neurotransmitter systems via its active compounds, notably withanolides. The herb exhibits antioxidant properties and interacts with multiple body systems, including the nervous, endocrine, and immune systems. By modulating cortisol levels and engaging with GABA receptors, Ashwagandha promotes a balanced physiological response to stress. Its bioavailability may differ based on the form used but is generally well-absorbed when taken orally.
Side effects
Ashwagandha is largely considered safe for short-term use; however, comprehensive data on long-term safety is limited. Common side effects, affecting more than 5% of users, include gastrointestinal disturbances, drowsiness, and possible allergic reactions. Less common effects reported in 1-5% of users may involve severe allergic reactions or drug interactions. Rarely, some users (under 1%) may experience serious reactions. Caution is advised for individuals taking sedatives, thyroid medications, or those with autoimmune disorders. Pregnant or breastfeeding women should avoid using Ashwagandha due to insufficient safety data. Medical supervision is recommended for those with thyroid conditions, diabetes, or pre-surgery planning.
Dosage
For stress and anxiety reduction, a typical minimum effective daily dose of Ashwagandha is around 300-500 mg of a standardized extract. Individuals aiming to enhance physical performance may benefit from higher dosages ranging from 330-1000 mg/day. Although there isn't a rigorously defined maximum dose, preliminary studies suggest that dosages up to 12,000 mg/day can be short-term safe. Ashwagandha can be taken at any time, but morning or bedtime is believed to better support stress management and improve sleep. Enhanced absorption occurs when the supplement is taken along with meals containing healthy fats, and standardized capsules or tablets are preferred for consistent potency.
