What Is Vitamin D3 with Sea-Iodine?

Maintaining healthy vitamin D levels helps support cognitive, bone and immune system health. It also helps maintain already-healthy blood pressure and supports a healthy inflammatory response, endothelial function and more.
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.

Iodine is essential for the supporting the production of thyroid hormones. But if you're watching your added salt intake, you may not be getting enough (most brands of common table salt have added iodine). Our formula delivers 125 mcg (5,000 IU) of vitamin D3 and 1,000 mcg of iodine in every capsule.
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.
Product Details
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.
Commercial salt makers add iodine to table salt to make up for this potential deficiency. However, those who don’t eat salt may miss out on an easy source of iodine. Our Vitamin D3 with Sea-Iodine™ formula delivers 1,000 mcg of iodine derived from sea plants to support healthy iodine levels.
Vitamin D3 and cognitive health
Vitamin D is important for maintaining healthy cognitive function as you age. Healthy serum vitamin D levels have been shown to correspond with better scores on cognitive health tests and healthy cognitive ability.
Vitamin D3 and bone and immune health
Vitamin D (accompanied by vitamin K and essential minerals) is essential for supporting the transport of calcium into the bone matrix. This is an important step in maintaining strong, healthy bones and teeth. Vitamin D also plays a critical role in healthy immune function.
Vitamin D3 and heart health
Vitamin D helps to regulate the body's calcium balance while facilitating calcium absorption into the bloodstream, promotes a healthy inflammatory response in the cardiovascular system and encourages healthy endothelial function. Vitamin D may also help inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range.
Get tested to assess dosage
This vitamin D3 supplement delivers 125 mcg (5,000 IU) of vitamin D3 as cholecalciferol per capsule. We suggest you take a 25-hydroxy vitamin D blood test after three months to assess and adjust your dosage. Evidence suggests that, for most people, an optimal target vitamin D blood level may be about 50–80 ng/mL.
