How Much Ashwagandha Per Day?
There is no single ashwagandha dose that answers this, and any page giving you one number without qualification is oversimplifying. The dose depends on the preparation, and preparations differ enormously.
Why one number does not work
Published trials use defined preparations — a specific extract, standardised to a specific withanolide percentage, at a specific daily amount. A dose quoted from such a trial applies to that preparation. Transferring it to a raw root powder, or to an extract of unknown ratio, is not a like-for-like translation.
Our guide to withanolides and extract ratios explains how to work out what a given product actually contains, which is the step that has to come before any dose comparison.
What labels state
Commercial products in this category state daily amounts across a wide range, and the range is wide precisely because the preparations differ. Products using a named standardised extract typically state a lower milligram figure than raw powder products, because the extract is concentrated.
Start at the label
The dose on the product you have bought is the dose that product was formulated around. Taking more than the label states on the basis of a figure read elsewhere — particularly one quoted for a different preparation — is how people end up at intakes nobody intended.
Duration matters as much as amount
Trials run for defined periods. Continuous open-ended use is a different pattern from what has been studied, and given the liver injury reports discussed in our safety guide, it is worth raising with a doctor rather than defaulting into.
Do not stack it unknowingly
Ashwagandha appears inside blended sleep, stress and testosterone formulas as well as being sold on its own. If you take more than one product, check each panel — the totals add up, and the blends often do not break out how much they contain.
Speak to a professional before starting if
You are pregnant or breastfeeding; you have a thyroid, liver or autoimmune condition; you take any regular medication; you are buying for a child; or you are considering a dose above the label. Please read our medical disclaimer.
