Naka’s Colloidal Vegetable Iodine Drops provide natural support for thyroid health. Iodine is an essential mineral often lacking in modern diets due to nutrient-depleted soil. As a key nutrient for the thyroid gland, it helps regulate hormone production and supports overall metabolism. Formulated with optimal sources such as kelp and seaweed, this supplement delivers organic, plant-based iodine that is easily absorbed by the body for maximum effectiveness.
