Does Ashwagandha Break a Fast? No

Reviewed by the FastTrack team · Updated June 2026
Short answer: No

Ashwagandha capsules do not break a fast. A capsule of root extract has essentially no calories, and a teaspoon of root powder about 5 to 10. Ashwagandha gummies are different: a two-gummy serving can carry 25 to 30 calories and 4 to 5 g of sugar.

Why a capsule keeps you fasted

Ashwagandha supplements contain a few hundred milligrams of root or leaf extract plus a little filler. That is far too little energy to raise insulin or end a fast, so a capsule can go in at any point in your fasting window.

What the evidence and the warnings say

Small trials suggest some preparations may help with stress and sleep, while the evidence for anxiety is unclear. Use for up to about 3 months appears safe for most adults. Rare but serious liver injury has been reported, it may raise thyroid hormone levels, and it should be avoided during pregnancy and breastfeeding. It may interact with thyroid, diabetes, blood pressure, sedative and immunosuppressant medicines, so ask your doctor or pharmacist first.

How much is safe

Take capsules at the dose on the label, during the fast or with a meal if they upset your stomach. Keep gummies and ashwagandha milk drinks for your eating window.
