Ashwagandha Supports Thyroid Function and More!
Withania somnifera (ashwagandha) is a valuable Ayurvedic botanical that has been used for centuries to support health on a variety of levels. In Ayurveda it is referred to as a rasayana or “rejuvenator” tonic. According to a review published in the African Journal of Traditional, Complementary and Alternative Medicine, “Rasayana is described as an herbal or metallic preparation that promotes a youthful state of physical and mental health and expands happiness.” Sounds wonderful!
Ashwagandha has a long history of use as an energy-supporting adaptogen, helping to support the body’s ability to manage stress. In addition, recent research indicates that ashwagandha can also help support thyroid function.
A 2018 prospective, randomized, double-blind, single-center, placebo-controlled trial featured in the Journal of Alternative and Complementary Medicine looked at 50 patients with elevated serum thyroid stimulating hormone (TSH) levels (4.5-10 μIU/L). The study participants were randomly assigned to receive 600 mg of ashwaganda daily or placebo for eight weeks. At the end of the study, patients had significantly improved serum TSH and T4 levels.
These results are consistent with a 2014 study published in the Journal of Ayurveda and Integrative Medicine. In that study, the ashwagandha group experienced a normalization of TSH and increases in T4. Interestingly, the purpose of this 2014 study was to evaluate the efficacy of ashwagandha to support cognitive function. The thyroid support properties were an unexpected observation. However, several studies, including a 2017 pilot study published in the Journal of Dietary Supplements, has demonstrated that ashwagandha may help support cognition and memory.
Ashwagandha is a key ingredient in many high-quality dietary supplements designed to support health on many levels, including thyroid function.
