Sound familiar?

The stress that won't clock out.

Tight shoulders by noon, a 3 p.m. crash, lying awake replaying the day. Chronic stress keeps cortisol elevated long after the moment has passed. Exactly the loop an adaptogen is built to interrupt.

How KSM-66® helps

A calmer stress response.

Targets cortisol at the source

Withanolides help regulate the HPA axis, the system that fires your stress response, supporting lower cortisol rather than masking symptoms.

The dose the studies used

600 mg per serving, standardized to 5% withanolides, the same serving used in the peer-reviewed stress trials, not a sprinkled-in fraction.

Calm without the fog

Ashwagandha is an adaptogen, not a sedative. It lowers reactivity so you stay clear and alert, just less braced.

27.9%

In a 60-day double-blind trial, adults taking 600 mg of KSM-66® saw serum cortisol (the body's main stress hormone) fall 27.9% versus placebo.

Finally, calm without the fog.

My mind used to race at night. Three weeks in, I'm just… less braced. Less reactive to traffic, to email, to my own thoughts.

Ashwagandha for stress · FAQ

Ashwagandha for stress, answered.

Does ashwagandha actually help with stress?
In multiple randomized, placebo-controlled human trials, KSM-66® Ashwagandha at 600 mg/day was associated with significant reductions in perceived stress and serum cortisol. Individual results vary, and it is not a treatment for an anxiety disorder.
How long until I feel less stressed?
Adaptogens build over weeks. Some notice a softer baseline in week one; most report meaningful change in weeks two to four. We give you 90 days to decide.
How much ashwagandha should I take for stress?
The clinically studied serving is 600 mg of KSM-66® daily: two Optibio capsules. One capsule is a lighter maintenance option.
