Ashwagandha has been used in Ayurveda for centuries, and the plant is common enough that the interesting question is not whether a supplement contains it but which extract.

Coyne use Shoden®, a patented Withania somnifera extract standardised to 35% withanolide glycosides. That figure is the point of the whole product. Withanolide glycosides are the bioactive fraction, and most ashwagandha extracts on the shelf are standardised at somewhere between 1.5% and 5%. Shoden sits an order of magnitude above that, which is why it is the extract used in a good deal of the published clinical work.

Sixty vegetable capsules.

Formulated free from common allergens and artificial additives, which for an Ayurvedic herb sold in a pharmacy matters more than it sounds.

From Coyne Healthcare, a South African manufacturer that has built its whole range around patented, standardised raw materials rather than generic bulk extract.
