Description
KSM-66 Ashwagandha – Pure, Advanced Stress Support Formula | 120 Caps
KSM-66 Ashwagandha is Strom’s single-ingredient stress support capsule, delivering a genuinely high 500mg dose of this patented ashwagandha extract in every capsule.
Rather than a proprietary blend diluting the dose, every single capsule lists exactly one ingredient at a level in line with published clinical research.
500mg of Patented Extract
This is the most clinically studied form of ashwagandha root extract available, and Strom delivers a full 500mg dose per capsule rather than a fraction of it.
Using a patented ashwagandha extract instead of a generic root powder means the active withanolide content is standardised batch to batch, not left to chance.
That consistency is exactly why this ingredient has become the reference point most published stress research is actually built around.
Real Research on Cortisol Levels
A 60-day, double-blind, placebo-controlled trial using 300mg of this patented ashwagandha extract daily reported a 27.9% reduction in serum cortisol levels among adults with chronic stress.
The same trial reported measurable improvements in relaxation, sleep and self-reported productivity alongside that drop.
A separate systematic review and meta-analysis has since confirmed the link between ashwagandha supplementation and reduced cortisol levels and anxiety scores across multiple independent studies.
Separate research in sub-elite team-sport athletes taking 600mg daily during high-load pre-season training also reported better-regulated stress hormone responses over a six-week period.
Why Choose This Formula
Many ashwagandha products use unstandardised root powder at unclear doses, making it impossible to know if you’re actually getting a research-relevant amount.
Choosing this specific extract removes that guesswork entirely, since 500mg is a dose directly comparable to what’s been studied in clinical trials.
Every batch is manufactured to the same transparent standard as the rest of the Strom range, with nothing hidden behind a proprietary name or a vague “adaptogen blend” label.
A long-term safety study covering 12 months of daily use also found no adverse effects on liver, kidney or thyroid function at this dose level.
Who It Suits
KSM-66 Ashwagandha suits anyone dealing with everyday stress who wants a single, properly dosed active ingredient rather than a multi-ingredient “calm” blend of unclear composition.
It also pairs naturally with Strom Sports SupportMAX Neuro, which uses the same KSM-66 Ashwagandha alongside Lion’s Mane for a broader cognitive and stress-focused stack.
How to Use This Product
Take one full capsule daily with food, or exactly as advised by a qualified healthcare professional.
Because ashwagandha builds up its full effect over consistent daily use, give it several weeks before judging whether it’s making a noticeable difference to your stress levels.

How does it affect cortisol levels? Clinical research has reported meaningful reductions here, alongside improved stress and anxiety scores over 60 days of consistent use.
Does it contain any known allergens? Yes — KSM-66 is extracted using a process involving milk, so it always carries a dairy allergen warning.
