Top 8 Best Selenium and Zinc Supplements for Thyroid

Written by Andrew Le, MD

UpdatedOctober 23, 2024

Selenium and zinc are two trace elements that are significant to thyroid health. The thyroid is the gland that has the function of synthesizing hormones that play a role in metabolism, growth and development. If one or the other is missing in the body, thyroid problems may occur and this may have various effects that include fatigue, excessive weight, and changes in moods.

People should consider taking the best selenium and zinc supplements to enhance the functioning of the thyroid gland or to prevent shortages. However, this does not mean that all the available selenium and zinc supplements are equally effective. The quality goes hand in hand with the kind of selenium and zinc used, dosage and other extra ingredients involved when selecting a supplement.
