Ashwagandha

Form, dose and role.

What it is

Withania somnifera, or ashwagandha, is an adaptogenic botanical with one of the larger human research bases in the category.

Why DEXO chose it

Ashwagandha is widely studied for stress and recovery, and it also has meaningful human research examining testosterone in men. That makes ashwagandha an important bridge between nighttime recovery and healthy male performance.

Why this form

Standardized Withania somnifera root extract. Research uses standardized root extract, so DEXO specifies standardized root extract. Where the final production lot uses a branded extract, the exact approved form is printed on the label.

Why this dose

600 mg per day is the amount most commonly used in randomized human trials of standardized root extract.

Its role in the system

Ashwagandha is the one ingredient that bridges the whole system: a meta-analysis of randomized sleep trials, randomized strength and VO2max trials at 600 mg/day, and pooled hormonal analyses including testosterone in men.
