Plant Milk Iodine Fortification Gap
Most plant milks lack iodine that dairy often provides—dairy-free athletes need iodized salt, seaweed, or clinician-guided plans.
A plant milk iodine fortification gap appears because most oat, almond, and pea cartons fortify calcium and B12 but omit iodine—unlike dairy, which picks up iodine from farming practices and feed. Strict plant-based diets without dairy, eggs, or iodized salt can run low on thyroid support nutrients.
Small amounts of seaweed or iodized salt help; kelp megadoses risk excess. Athletes should not self-treat thyroid symptoms with iodine alone.
Common questions
-
Should I take kelp for iodine on a vegan diet?
Only with clinician guidance—kelp iodine content varies wildly and excess can harm thyroid function. Iodized salt and small seaweed servings are safer starting points.
