The thyroid gland secretes hormones that play essential roles in growth and metabolism. Moderate thyroid underactivity may impact key metabolic functions relating to digestion, weight gain, and fatigue. (source)
The thyroid gland regulates cellular growth and metabolism through hormone production. Inefficient thyroid hormone production can disrupt metabolism, causing fatigue and weakness. Maintaining thyroid efficiency enhances cellular function, boosting energy levels and overall mental and physical performance.
Supplement with Vitamin D: Vitamin D intake has been shown to normalize markers of an underactive thyroid. (source) Vitamin D improves thyroid underactivity primarily through its immunomodulatory effects, reducing autoimmune activity and improving thyroid function. It decreases the levels of harmful auto-antibodies and supports better regulation of thyroid hormones, thereby improving thyroid underactivity. (source, source) Recommendation: Supplement with up to 2,000 IU of vitamin D daily.
Supplement with Ashwagandha: Ashwagandha has been shown to help normalize markers of thyroid underactivity. (source) Ashwagandha enhances the secretion of thyroid hormones and reduces oxidative stress, thereby supporting overall thyroid health. (source, source) Recommendation: Supplement with at least 240 mg of Ashwagandha daily.
