Ashwagandha is one of the more researched adaptogens available, with genuinely solid evidence for stress and cortisol regulation specifically — though it comes with one safety consideration (thyroid function) that’s easy to overlook amid the general “wellness herb” marketing. For the full research breakdown, including dosing by goal and who should be cautious, see our complete guide to Ashwagandha. Below you’ll find our picks, chosen for standardised withanolide content and quality certification.

Choosing an Ashwagandha Supplement
KSM-66 and Sensoril are the two most-studied standardised root extracts, generally preferred over root-and-leaf blends for the research base behind them. Look for products stating actual withanolide content (commonly 5-10%) rather than just total extract weight. Commonly referenced doses range from 300-600mg daily for general use up to 1,000mg+ for performance-specific goals, generally taken with food. If you have a thyroid condition, take thyroid medication, or are pregnant or breastfeeding, check with your GP before starting — our full guide covers this and other safety considerations in more detail.
