Thyro Complex

Based on Examine, Wikipedia, and 23 other sources

Overview

The effectiveness of Thyro Complex is largely based on the inclusion of iodine, which is essential for thyroid function. However, the high dose of iodine and the inclusion of various glandular extracts with unproven oral efficacy and standardization raise concerns about overall effectiveness and potential side effects.

The Good

Provides essential iodine, critical for thyroid hormone synthesis.

Kelp provides iodine from a natural source.

The Bad

Extremely high iodine dose (900 mcg) can be risky for thyroid health, potentially causing dysfunction.

Inclusion of Bovine Thyroid Powder means the product contains active thyroid hormones, requiring careful medical supervision and raising concerns for individuals who may not need or tolerate additional thyroid hormones.

Efficacy of other glandular powders (Porcine Adrenal, Bovine Pituitary, Porcine Spleen) for oral supplementation is poorly supported by scientific research and their hormone content is not standardized.

Is it for you?

Best For: Individuals seeking non-hormonal thyroid support, those looking for iodine supplementation

Skip If: You have pre-existing thyroid conditions or are taking medications without consulting a healthcare provider
