Supplement monograph

Iodine

A thyroid-essential mineral where baseline intake, thyroid disease history, pregnancy context, and medication timing determine whether supplementation is rational.

Practical read

Treat iodine as a thyroid-context nutrient, not a generic energy supplement. Keep use consistent, avoid high-dose kelp products, and separate thyroid-medication timing from mineral-heavy routines.

Decision frame

Timing rule

Treat iodine as a thyroid-context nutrient, not a generic energy supplement. Keep use consistent, avoid high-dose kelp products, and separate thyroid-medication timing from mineral-heavy routines.
