Iodine supplements boost thyroid function in everyone
evidence
The Claim
Many believe that taking iodine supplements can universally enhance thyroid function, as iodine is a crucial component of thyroid hormones. This leads to the assumption that more iodine equates to better thyroid health for all.
Origin
This myth stems from the known role of iodine in thyroid hormone production and has been perpetuated by supplement marketing and anecdotal reports.
What Science Says
Research indicates that while iodine is essential for thyroid health, excessive intake can actually impair thyroid function, especially in individuals with adequate dietary iodine. Systematic reviews and population studies show that iodine supplementation is beneficial primarily in populations with iodine deficiency, while it may not have positive effects in iodine-sufficient individuals.
Verdict
Mostly False
