Ashwagandha safety
- NIH says ashwagandha appears well tolerated for up to about 3 months, and that its long-term safety is not known.[1][2]
- Rare cases of liver injury have been linked to ashwagandha supplements. Stop and see a doctor if you notice yellow skin or eyes, dark urine or itching.[1][2]
- NCCIH says to avoid ashwagandha during pregnancy and not to use it while breastfeeding. It is also not recommended before surgery or for people with autoimmune or thyroid disorders.[2]
- Ashwagandha might interact with medicines for diabetes and high blood pressure, immunosuppressants, sedatives, anti-seizure medicines and thyroid hormone medicines.[1][2]
What Is Ashwagandha?
- The Plant – Ashwagandha (Withania somnifera) is an evergreen shrub, also called Indian ginseng or winter cherry, although it is not related to ginseng. The name comes from Sanskrit words for horse and smell, because the root is said to smell like a wet horse.[1]
- Traditional Use – The root has been used in Ayurvedic and Unani medicine in India as an adaptogen, a loose term for something that helps a person adapt to stressors.[1]
- Root or Leaf – Most commercial supplements use root extract, and some use root and leaf. The two parts differ in chemistry, so the product name and the supplement facts panel matter.[1][2]
- Not Medicine – Ashwagandha supplements are sold as dietary supplements, and the FDA does not approve them before they are sold.[2][3]
Forms and Doses
- Capsules and Tablets – The simplest option. Counts on this page run from 60 to 180, and stated doses run from 670 mg to 2100 mg, so compare the serving size as well as the bottle count.
- Powder – Ground root that you stir into smoothies, coffee or warm milk. It has an earthy, bitter taste and no capsule shell. Our organic turmeric powder picks follow the same stir-in idea.
- Extracts – Many studies use standardized root extracts, measured by withanolide content, rather than plain root powder. Doses and extracts differ widely from study to study.[1]
- Black Pepper – Four of the seven picks add black pepper or piperine to the formula. Check the label if you take medicine, and ask your pharmacist about interactions.
What to Check on an Ashwagandha Label
- Plant Part – Look for root on the supplement facts panel. NCCIH notes that supplements contain root, leaf, or root and leaf extracts.[2]
- Amount Per Serving – The supplement facts panel shows the active ingredient and the amount per serving. The serving can be one capsule or several.[3]
- Organic Seal – Look for the USDA Organic seal if you want a certified organic product.[4]
- Third-Party Seals – Independent groups such as NSF International and U.S. Pharmacopeia test supplements. Their seals show a product was made properly and holds what the label states, but they do not guarantee safety or effectiveness.[3]
- Count and Price – Divide the price by the number of servings, not capsules, to compare products fairly.
What the Research Says
The NIH Office of Dietary Supplements reviewed small, short randomized trials in which ashwagandha extracts lowered stress and anxiety scores and cortisol compared with placebo, and improved sleep, especially in people with insomnia.[1] NCCIH says some preparations may be effective for insomnia and stress, that the evidence on anxiety is unclear, and that there is not enough evidence for conditions such as athletic performance, cognitive function, diabetes or menopause.[2] Both agencies note that studies used many different preparations and doses, which makes it hard to name a recommended product or amount.[1][2]How We Chose These Products
