Organic Ashwagandha Supercritical Co2 Extract
Also known as: Ashwagandha, Indian ginseng, Winter cherry, Withania somnifera
Overview
Ashwagandha, scientifically known as *Withania somnifera*, is a plant-based supplement with a long history of use in Ayurvedic medicine. Primarily sourced from the roots of the plant, it is classified as an adaptogen, meaning it is believed to help the body adapt to various stressors. Ashwagandha is available in several forms, including capsules, powders, and liquid extracts, with supercritical CO2 extracts potentially offering enhanced bioavailability. Research suggests that Ashwagandha may have beneficial effects on stress reduction, anxiety management, sleep quality, and physical performance. However, the strength of evidence varies, and further high-quality studies are needed to validate these effects across diverse populations. Its growing popularity is driven by its potential to support overall well-being and resilience in the face of daily stressors.
Benefits
Ashwagandha has several evidence-based benefits. It significantly reduces stress and anxiety levels, as demonstrated in a systematic review and meta-analysis (SMD: -1.55 for anxiety, SMD: -1.75 for stress). Another key benefit is improved sleep quality, with studies showing significant improvements in sleep metrics compared to placebo (SMD -0.59). Ashwagandha may also enhance physical performance, including muscle strength and cardiorespiratory fitness, although more research is needed in this area. These benefits are generally observed in healthy adults, but further investigation is required to understand its effects in other populations, such as children and the elderly. The efficacy of Ashwagandha can vary based on the extract type and individual factors.
How it works
Ashwagandha functions primarily through its adaptogenic properties, which help regulate the body's stress response by modulating cortisol levels. It also enhances antioxidant defenses, contributing to overall cellular protection. The herb interacts with the nervous and endocrine systems, influencing various physiological processes. Ashwagandha may target molecular pathways related to stress, inflammation, and immune function. Its bioavailability can vary depending on the extraction method, with supercritical CO2 extracts potentially offering better absorption. By balancing these systems, Ashwagandha helps the body maintain homeostasis under stressful conditions.
Side effects
Ashwagandha is generally considered safe when used appropriately, but it can cause side effects in some individuals. Common side effects include mild gastrointestinal upset, headache, and allergic dermatitis. Less common side effects may involve changes in heart rate or blood pressure, particularly in sensitive individuals. Rare side effects are not well-documented but could include severe allergic reactions. Ashwagandha may interact with sedatives, thyroid medications, and blood thinners, so caution is advised when combining it with these drugs. It is contraindicated in pregnancy and breastfeeding due to insufficient safety data. Individuals with autoimmune diseases or thyroid disorders should use Ashwagandha with caution. It's important to start with a low dose to assess tolerance and consult a healthcare provider if any adverse effects occur.
Dosage
The minimum effective dose of Ashwagandha typically starts at 300-500 mg per day. For stress and anxiety reduction, an optimal dosage range is 300-600 mg per day. Higher doses, up to 1,250 mg per day, may be used for enhancing physical performance, but should be approached with caution. It is best taken with meals to minimize gastrointestinal side effects. Supercritical CO2 extracts may offer better bioavailability. While generally safe, exceeding the recommended dosage is not advised. It's important to monitor for any adverse effects and consult with a healthcare provider to determine the appropriate dosage for individual needs.
