Does what it says on the tin. The capsule is smaller than the magnesium oxide one I was taking, which matters when it is every day.

What’s inside
One dose, taken apart.
Most supplements hide their actives inside a proprietary blend. This bottle has four facts in it — and they are all on the label.
RC-02 · 60 ct What’s in the bottle
One compound, declared.
KSM-66 ashwagandha root extract, standardized to 5% withanolides. Root only — no leaf, no proprietary blend, and the standardization printed on the label.

The full list
Other ingredients: none.
Not a shortened list. The whole list. One active compound, the capsule that holds it, and nothing added for volume, colour or flavour.
We don’t flavour anything, because flavouring is fillers you didn’t ask for.

No complaints. Capsule has a faint earthy smell when you open the bottle, which I gather is normal for the ingredient.
Extract ratio is stated plainly on the label rather than buried in a blend, which is why I picked this over two cheaper options.
Questions
Frequently asked
Common questions about Ashwagandha
What does single-ingredient actually mean?
One active compound per bottle, at one dose, printed on the front panel. No proprietary blends, no undisclosed filler amounts, no second active hiding behind a trademarked name.
Do you publish test results?
Not yet. No lot has been produced, so there is nothing to test. Independent testing begins with Lot 001, and each lot's certificate will be linked from its product page and findable by the lot code printed on the bottle. Until then, everything we claim is printed on the front panel and can be checked by reading it.
Why is the dose on the front of the label?
Because it is the number that decides whether a product does anything. Putting it on the front removes the choice to bury it.
When can I actually order?
Not yet. Lot 001 has not been produced, so nothing can ship and we are not taking card payments — that is why the buy button is a notify form. Leave an email and you will hear from us the day stock lands, with the shipping timetable at that point.
