Iodine might seem like an unusual ingredient in a skin supplement, but the connection runs through your thyroid gland. Gelagen contains 42mcg of iodine (28% DV) as potassium iodide, and here is why.
Your thyroid gland uses iodine to produce thyroid hormones (T3 and T4). These hormones directly regulate the growth rate and turnover cycle of skin, hair and nail cells. Hypothyroidism (low thyroid function) causes dry skin, brittle nails and hair thinning.
The recommended daily intake for iodine is 150mcg for adults. Our 42mcg (28% DV) is a supportive contribution, not a therapeutic thyroid dose. Most people get additional iodine from iodized salt, seafood and dairy products.
If you have a diagnosed thyroid condition (hypothyroidism, hyperthyroidism, Hashimoto's thyroiditis, Graves' disease), consult your endocrinologist before taking any iodine-containing supplement. Even small doses can affect thyroid medication dosing.
Iodine is one piece of the thyroid-skin connection. Combined with the B-complex vitamins, zinc and biotin in our formula, it supports the endocrine environment that governs tissue regeneration. See how all five pathways work together.
