The extract

Made with KSM-66®

Optibio uses KSM-66® ashwagandha root extract, produced by Ixoreal Biomed. Optibio is a licensed KSM-66® brand.

Root only

The part that matters

KSM-66® is made exclusively from the root, not the leaf, through a 14 day green chemistry extraction without alcohol or synthetic solvents.

Standardized

5% withanolides, every batch

Standardization means the amount of active compounds is measured and consistent. No guessing between bottles, no drift between batches.

Tested before it reaches you.

Independent testing

Third party tested, every batch

Every production batch is tested by an independent lab for purity and potency, including screening across 35 substances for quality.

Manufacturing

Made in the USA

Manufactured in a GMP certified facility in the United States. Vegan capsules, no GMOs, no gluten. Other ingredients: vegetable cellulose capsule and rice flour, nothing else.
