The most studied herb in Ayurveda — and the one people most often give up on too early.
Ashwagandha is the herb people ask about most, and the one most often abandoned before it has had a fair run. This is what it is, what the research actually looked at, and what two honest months with it look like.
What it is
Withania somnifera — a root, not a leaf or a berry. In Ayurveda it is classed as a rasayana, a rejuvenative: something taken steadily over long periods rather than reached for when a problem appears. The name translates roughly as “smell of the horse,” which is a fair description of the raw root.
A root
Withania somnifera. Warming, in the traditional framing.
An adaptogen
A term for herbs studied around the stress response.
With food
Taken with a meal, which settles most first-week complaints.
What “adaptogen” actually means
It is a category term, not a mechanism. It describes plants that have been studied for how the body handles stress, rather than for producing an immediate effect you can feel. That distinction matters more than anything else on this page: you are not chasing a peak the way you would with caffeine, so there is nothing to notice on day one, and nothing has gone wrong if you do not.

Dose and duration
Published reviews have generally looked at roughly 500 to 600mg a day, often split as 300mg twice daily, over six to eight weeks. One trial ran ninety days. That range is the most useful thing to take from the research — not because it guarantees anything, but because it tells you what a fair test looks like.
A hundred-tablet bottle at one a day is about three months. That is roughly the right length for an honest trial, and it is why we sell it in that size.
Taking it for five nights, feeling nothing, and stopping. That is not a failed trial — it is not a trial at all. If you are not willing to give it two months, it is better not to start.
Morning or evening?
Either. It is neither a stimulant nor a sedative, so the timing follows your reason rather than the other way round — morning if you want it through the day, evening if you want it as part of winding down. This goes through the timing question properly.
With food, always. Ashwagandha on an empty stomach is the most common cause of the mild stomach upset some people report in the first week, and taking it alongside a meal usually settles it.

Write one line a day. How you slept, or how the day felt. Eight weeks is long enough that memory becomes unreliable, and a slow change is invisible without a record.
And take one thing at a time. If you start ashwagandha, shilajit and moringa in the same week and something shifts, you have learned nothing about which one did it.
Who should avoid it
Ashwagandha is not universally suitable, and the cautions are real rather than boilerplate. The NIH Office of Dietary Supplements notes it should be avoided in pregnancy and while breastfeeding, and advises caution for anyone with a thyroid condition or a hormone-sensitive condition. There are also a small number of reports of effects on liver function, and long-term safety has not been established.
You are pregnant or breastfeeding. You have a thyroid condition. You have a hormone-sensitive condition. You take prescription medication. You have surgery scheduled in the next two weeks.
If you are choosing between herbs
Ashwagandha and shatavari are the pair people most often weigh against each other — one warming, one cooling. If you are starting from nothing at all, this covers how to pick a first herb and how to run the first eight weeks so you actually learn something.
