Lifeplan Sea Kelp 400mg tablet is a food supplement developed to support healthy thyroid function. Contains 400mg of Sea kelp powder sourced from the West coast of Ireland. Sea Kelp is a type of marine algae often found growing near the coastline, where the water is shallower and more nutrient rich and is a rich natural source of Iodine. Iodine is used by the thyroid lano reduce thyroid hormones. The hormones triiodothyronine (T3) and thyroxine (T4) regulate the body's metabolism and also the metabolism of food in the intestines. Sea kelp is also an excellent source of iodine, which has been shown to be essential for healthy thyroid function. Thyroids require iodine to function properly. Your body does not manufacture iodine, so it's important to get it through your diet. Being deficient in iodine can lead to goiter-an enlargement of the thyroid gland-as well as impact your metabolism. Lifeplan's Sea Kelp supplements contain pure Sea Kelp powder. Lifeplan Sea Kelp 400mg is vegan certified and suitable for vegan and vegetarians.
