Life Extension Vitamins D and K with Sea-Iodine for Thyroid, 60 Capsules | With Vitamin D3, Vitamin K1 & K2 & Iodine, Supports Immune, Bone, Arterial & Thyroid Health, Non-GMO & Gluten-Free

Supports a healthy immune response—Are you getting enough vitamin D3 We’ve combined several nutrients diets often lack, like vitamin D, which helps maintain a balanced immune system along with other benefits, from bone health to cognitive function

Helps maintain strong bones—Vitamin D is necessary for bone health because, along with vitamin K, it gets calcium into your bones. Not only that, but we include multiple types of vitamin K in this formula: vitamin K1 as well as two types of vitamin K2.

Supports thyroid health—There’s one more nutrient some people may lack: iodine. Common in table salt (and missing from many healthy diets), iodine is used to make thyroid hormones. Your thyroid helps regulate your body’s metabolism.
