Iodine

Iodine is an essential trace mineral needed to make thyroid hormones. It matters most when intake is low, pregnancy needs are higher, or diet patterns make deficiency more likely.

Iodine is essential for thyroid hormone production and correcting low intake matters, especially around pregnancy, but routine extra iodine is not automatically better.

Headline Finding

WHO supports salt iodization to prevent deficiency disorders; pregnancy reviews show clearer benefit in severe deficiency than in mild or sufficient populations.

Dose Context

Needs are usually met through iodized salt, seafood, dairy, eggs, or prenatal formulas; supplement dose should reflect diet, pregnancy status, and thyroid history.

Important Caveat

Both too little and too much iodine can disrupt thyroid function. Thyroid disease, pregnancy, and medication use make clinician guidance important.

How To Read This Rating

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
