Ashwagandha Root Concentrate
Also known as: Ashwagandha, Indian ginseng, Winter cherry, *Withania somnifera*
Overview
Ashwagandha (*Withania somnifera*) is a herb native to India, Africa, and the Middle East, traditionally utilized in Ayurvedic medicine. Known primarily for its adaptogenic properties, Ashwagandha aids the body in coping with stress. The root extract is the most frequently utilized form, rich in bioactive compounds such as withanolides. The body of research surrounding Ashwagandha has expanded substantially, focusing on its influence on stress, anxiety, sleep improvement, and cognitive function. Although some studies indicate promising outcomes, consistent research quality is necessary to elucidate the full extent of its benefits and limitations. The most common forms of Ashwagandha supplements include capsules and powders.
Benefits
Clinical research indicates that Ashwagandha significantly improves sleep quality and decreases anxiety levels, particularly among adults with insomnia. A meta-analysis with 400 participants across five trials reported a standardized mean difference (SMD) of -0.59 for sleep quality, suggesting a moderate effect size. Additionally, various systematic reviews affirm its role in stress reduction; however, effects on mental alertness require further investigation. The benefits of supplementation are typically realized after several weeks, making consistent use important for therapeutic outcomes.
How it works
Ashwagandha functions primarily through its interaction with the body's stress response systems. It potentially modulates cortisol levels, which could influence anxiety and stress responses. The active constituents, particularly withanolides, are known to engage with GABA receptors and other neurotransmitter systems, impacting the nervous and endocrine systems. While the absorption and bioavailability of these compounds remain understudied, they are generally believed to be absorbed effectively when ingested orally.
Side effects
Generally considered safe when taken appropriately, Ashwagandha may cause minor side effects, primarily gastrointestinal upset, which is rare. Allergic reactions have been noted but are uncommon, and no rare side effects have been well-documented in the literature. Caution is advised for individuals on sedative medications or thyroid medications due to potential interactions. Furthermore, due to insufficient safety data, Ashwagandha is contraindicated during pregnancy and breastfeeding. Special populations, particularly those with autoimmune diseases, may require additional caution due to potential immune modulation.
Dosage
The recommended minimum effective dose of Ashwagandha starts at 300 mg per day, with typical optimal dosages ranging from 300 to 600 mg daily. Some studies indicate higher usages, up to 1200 mg, but safety data for doses above this threshold is limited. It is advisable to consume the supplement with meals to mitigate gastrointestinal discomfort. The extract form and specific withanolide content can vary significantly, and absorption may be enhanced when taken with fatty meals.
