Understanding whether ashwagandha is behind a flare can help you manage your health safely.

Hormonal effects
Ashwagandha may influence cortisol and thyroid hormones. Fluctuations in these hormones can indirectly affect immune regulation.
Individual sensitivity
Genetic factors, existing medications, and the underlying type of autoimmune disease all play a role in how you react.
If you start or increase your ashwagandha dose and notice any of the following changes within days to weeks, it could be a red flag:

Always involve your healthcare provider in decisions about supplements—especially if you have an autoimmune condition. A doctor can:
