Ashwagandha Side Effects
What are the side effects of ashwagandha supplements?
Although ashwagandha supplements (typically taken for anxiety or stress) are generally well-tolerated when taken short-term (weeks to a few months) in typical dosages, mild to moderate side effects such as headache, sleepiness, and stomach upset have been reported in clinical studies. Rarely, allergic reactions and rapid heartbeat have been reported. There are no long-term studies on the safety of ashwagandha supplements.
Be aware, however, that ashwagandha can potentially lower blood pressure and blood sugar, and increase thyroid hormone levels as discussed in the Concerns and Cautions section of the Ashwagandha Supplements Review. The Review includes ConsumerLab’s tests and reviews of popular ashwagandha supplements, its Top Pick, and the evidence regarding ashwagandha for anxiety, physical and cognitive performance, and other uses.
