Ashwagandha KSM-66: price per 600 mg

We count the weight of extract per serving. Where a label quotes a “whole herb equivalent” (for example “5,000 mg from a 10:1 extract”), we use the actual extract weight. Branded, standardised extracts are compared separately from unbranded ones.

Prices last checked: 17 September 2026. Ranked purely by price per 600 mg — a comparison unit, not a recommendation. We may earn commission from these links; it never affects the order.
