50–300mg of standardized extract per can. Studied doses start around 300mg daily.
Afternoon or evening — it's not stimulating.

What Ashwagandha actually is
Ashwagandha (Withania somnifera) is a root used in Ayurvedic practice for centuries and now the headline ingredient in half the calm-branded cans at the grocery store. In drinks it usually shows up as a standardized extract — KSM-66 or Sensoril — rather than raw powder.
What it feels like
Here's what nobody tells you: you probably won't feel a single can. Ashwagandha isn't a switch, it's a slow dial. People who notice something describe it after a couple of weeks of daily use — less jaw-clenching at 4pm, an easier time putting the day down.
What the research says
- • Multiple randomized trials link daily standardized ashwagandha extract to lower self-reported stress scores over 8 weeks.
- • Several of those trials also measured reduced morning cortisol compared with placebo.
- • Studied doses usually run 300–600mg per day of standardized extract — often more than a single beverage delivers.
How to read the label
- • Look for a named extract (KSM-66, Sensoril) with milligrams listed.
- • "Proprietary blend" with no mg breakdown means you can't know your dose.
- • Check whether the can is a single serving or two.
Before you make it a daily habit
- • Can interact with thyroid medication, sedatives, and immunosuppressants.
- • Not recommended during pregnancy — talk to your own clinician first.
- • Some people get mild stomach upset on an empty stomach.

Frequently asked questions
How much ashwagandha is in an adaptogen drink?
Most cans list somewhere between 50mg and 300mg of standardized extract. Clinical trials typically used 300–600mg daily, so a single drink often sits below the studied range. If dose matters to you, buy the brands that print the milligrams.
How long does ashwagandha take to work?
Research on stress and cortisol generally measures results after 4–8 weeks of daily use. It's a cumulative ingredient, not an instant one — judge it by how a month feels, not by one can.
Can you drink ashwagandha every day?
Daily use is how it was studied, and most functional drinks are formulated for it. If you take thyroid medication, sedatives, or immunosuppressants, or you're pregnant, check with your own clinician before making it a habit.
