Overview

Nutricost's capsules are built around KSM-66, a named full-spectrum ashwagandha root extract standardized to 5% withanolides, at 600mg per serving. The brand also adds BioPerine, a black pepper extract commonly included in supplements alongside other active ingredients, and packages it in 60 veggie capsules.

At $14.95, it is priced well below many other KSM-66 products in this category, and the label lists it as gluten free. The allergen information does note milk, which is worth checking if that is a concern.

What stands out most is the purchase volume: about 20,000 units sold in the last month against 4,002 ratings at a 4.6 average, by far the highest monthly volume of the products covered here, suggesting this is one of the more popular value picks in the ashwagandha category.

With 4,002 ratings at a 4.6 average and about 20,000 units sold in the past month, this is the highest-volume product in this group of ashwagandha listings, pointing to broad, sustained demand at its price point.
