Ashwagandha Root May Help Improve Subclinical Hypothyroidism
Subclinical hypothyroidism is mild thyroid failure without obvious symptoms of thyroid deficiency that occurs in 3%-8% of the global population. A recent study suggests that ashwagandha root may help improve subclinical hypothyroidism.
Participants in the study included 50 people between the ages of 18 and 50 with thyroid-stimulating hormone (TSH) levels of 4.5 to 10 mIU/L and serum levels of T3 and T4 (markers of thyroid function) in the normal range. Over the course of eight weeks, half of the group took 300 mg of ashwagandha, while the other half took a placebo.
The ashwagandha group had a 12.5% reduction in TSH levels at the four-week mark and a 17.4% reduction at the end of the study. The researchers also noted a 9.4% increase in T4 levels at the four-week mark and a 19.6% increase at the eight-week mark in the ashwagandha group. Additionally, T3 levels increased 18.6% at four week and 41.5% at eight weeks.
In comparison, the placebo group did not show changes in TSH or T4 levels and their serum T3 levels decreased.
Researchers from Sudbhawana Hospital in India conducted the study. It was published online ahead of print on August 22, 2017, in the Journal of Alternative Complementary Medicine.
Ashwagandha has been used in Ayurvedic medicine for over 4,000 years. Previous studies suggest that Ashwagandha may help improve memory, cognitive function and brain health, increase strength, and help with sexual dysfunctions. The best way to consume Ashwagandha is by taking a high quality supplement.
