In a randomized, double-blind, placebo-controlled trial, 50 participants with subclinical hypothyroidism were assigned to take 600 mg of a 100% aqueous extract of ashwagandha (5% withanolides) or placebo daily for 8 weeks.
There was a notable, statistically significant increase in T3 and T4 and a notable reduction in TGH in the ashwagandha group compared with the placebo group.
There was no notable difference between groups for adverse events.
