- Possible interference with thyroid function tests
Certain groups should avoid or consult a healthcare provider before using ashwagandha:Pregnant women (may cause early delivery), people with autoimmune conditions, those on thyroid medications, or individuals with hormone-sensitive prostate cancer.
