Many people need 125 mcg (5,000 IU) to 200 mcg (8,000 IU) of vitamin D3 a day to promote optimal health. This formula has 125 mcg (5,000 IU) of vitamin D3.

Why Should I Supplement With Vitamin D3 with Sea-Iodine™?

Customer: To me, there's nothing better than being outside on a really nice day. Whether I'm working in my garden or taking a walk with my family, we all love the outdoors. But during my last checkup, the doctor noticed that I wasn't getting enough vitamin D.

Michael A. Smith, MD: From your brain to your heart, your bones to your immune system, vitamin D affects nearly every cell in your body and is critical for optimal health. Even if you spend a lot of time outdoors, your body may not be producing enough of this important vitamin. In fact, studies show that people are really low in vitamin D—and that's why doctors are recommending it to their patients more than ever.

Customer: So, my body needs more vitamin D, but there are all these different doses and options. How can I decide which is best for me?

Michael A. Smith, MD: Like all of our products, Life Extension’s Vitamin D3 is made with the highest quality standards. We recommend taking 5,000 international units a day, but we offer doses ranging from 1,000 to 7,000 units depending on your vitamin D blood level. Be sure to check with your doctor to see which one is right for you. We also offer Vitamins D and K with Sea-Iodine™ for a complete vitamin D formulation.

Customer: Three weeks in, and vitamin D has really made an impact on my whole life. I have more energy and overall, I feel for lack of a better word…sunnier.

Dr. Michael A. Smith, MD: Director of Education and Spokesperson for Life Extension.

Iodine is essential for thyroid health

Iodine is a trace element essential for supporting the production of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). The thyroid gland actively absorbs iodide from the blood in order to make and release these hormones. Iodine is abundant in seafood and sea vegetables, but not everyone likes or has access to marine foods and vegan diets sometimes lack adequate iodine.1
