Ashwagandha

Ashwagandha (Withania somnifera) is a plant used in traditional Ayurvedic practice, and it is one of the most popular botanical supplements in the UK. This range brings together ashwagandha capsules, tablets, gummies and powders, including products made with KSM-66, a branded root extract that is widely used in sports and wellness supplements.

Products differ in three main ways. The extract: many use a standardised root extract (such as KSM-66), labelled with the percentage of withanolides, while others use whole root powder. The strength: compare milligrams of extract per serving rather than per capsule. The formula: some products contain ashwagandha alone, while others combine it with ingredients such as rhodiola, ginseng or magnesium. There are no authorised health claims for ashwagandha, so we describe these products by form and strength only. Labels advise against use during pregnancy or breastfeeding; follow the warnings on each label and speak to a healthcare professional if you take medication. Read our ashwagandha guide for more on extracts and labels.

How to compare ashwagandha

  • Extract type: root extract, standardised extract or whole root powder.
  • Withanolides: standardised extracts state a percentage on the label.
