Lab-tested ashwagandha in the UK and EU (2026)

Ashwagandha is a root, and plants can take up heavy metals such as lead and cadmium from soil. Published independent lab reports let you check a specific batch rather than rely on a "tested" claim. This guide lists the ashwagandha products in our directory with a public third-party report we could open and read. It does not rank products, assess effectiveness, or give health advice.

How we chose these

The report is public, opens directly, and names ashwagandha and the batch or lot.
It reports lead (and usually cadmium, mercury, arsenic) from a third-party lab.
It is dated 2024–2026. Older or expired-batch reports are listed separately as outdated.
