Transparent LabsKSM-66 AshwagandhaWhat are you hoping to improve?
Pick a goal and we’ll tell you, honestly, whether KSM-66 Ashwagandha is the right fit, or what would suit you better.
Ashwagandha is the adaptogen the modern research keeps returning to, a centuries-old root with a genuinely contemporary evidence base for lowering perceived stress, softening cortisol and helping the nervous system find a lower gear without dulling you. The extract is what matters, and KSM-66 is the gold standard: a full-spectrum root extract used in more clinical trials than any other, dosed here at the 600mg the studies are built on rather than a fraction of it.

Calm, focused attention, and the amino acid that takes the jitter out of caffeine.

An adaptogen for mental stamina, the one to reach for when fatigue, not anxiety, is the problem.

The evening form of magnesium: highly absorbed, gentle on digestion and carried by naturally calming glycine.

Overall sentiment

Gentle on a sensitive stomach, and I feel like myself again. I had tried two other glandulars before this and neither sat right.
1 week ago
I was sceptical about glandulars, but my mid-afternoon crash has genuinely eased. One capsule with breakfast and I forget about it.
2 weeks ago
Not a stimulant, which is exactly what I wanted. It took about ten days, then I realised I wasn’t dreading the afternoon any more.
3 weeks ago
Bought after a blood panel flagged a flat cortisol curve. Easy to take, no jitters, and the sourcing is refreshingly transparent.

Training hard through a stressful stretch and this has helped me bounce back between sessions. Already on my second bottle.
1 month ago
No frills, one ingredient, a sensible dose. I appreciate that it is designed to be used for a season rather than forever.
