What the AI looks for in Ashwagandha

Extract type: Prefer a named, studied extract (KSM-66 or Sensoril) with withanolide content stated. Most human trials used these extracts, and their doses don't transfer to raw powder.
Plant part: Root-only extracts are preferable to root-plus-leaf. Leaf has a different withanolide profile and less traditional use.
Safety signals: Stop and seek care if you notice jaundice or dark urine. Rare cases of liver injury have been reported.

Brands that matter

Nutricost: Budget KSM-66 capsules.
Organic India: Organic whole root.
Himalaya: Ayurvedic ashwagandha singles.

What to avoid

Gummies with very low or unstated extract dose
Use during pregnancy
Combining it with thyroid hormone without monitoring

Questions

KSM-66 or Sensoril?

Both are studied root-based extracts. KSM-66 is root-only and more widely trialed; Sensoril includes leaf, is more concentrated in withanolides and is dosed lower.
