Ashwagandha KSM-66^®

Our Ashwagandha KSM-66® (500mg) is 100% organic and the most clinically trialled and world-wide acclaimed form of this herb. Ashwagandha KSM-66® is a full-spectrum extract with the highest concentration of withanolides, taken only from the root of the plant. Standard Ashwagandha supplements extract withanolides from the leaves, which have a lower concentration and potency. The KSM-66® extraction process does not involve any chemicals, alcohol or solvents.

The compostable pouch opens easily and keeps contents fresh. With a neutral taste, each serving provides 500mg KSM-66 root extract with five per cent withanolides, a clinically backed form with proven absorption. Vegan, allergen free and additive free, it’s well priced at about 43p per day and feels high quality for a single-ingredient supplement."
