Your skin produces vitamin D when in direct sunlight, but you should not get your vitamin D from unprotected sun exposure or indoor tanning devices because of the potential effects on skin health.
Iodine is a trace element essential for the production of thyroid hormones, and vitamin K is an essential nutrient that promotes both arterial and bone health.
Iodine is essential for thyroid health
Iodine is a trace element necessary for the production of the thyroid hormones triiodothyronine (T3) and thyroxine (T4).1 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.2
Commercial salt makers add iodine to table salt to make up for this potential deficiency. However, we now know the health risks of eating too much salt, so health-conscious people may miss out on an easy source of iodine. Vitamins D and K with Sea-Iodine™ delivers 1,000 mcg of iodine to support healthy iodine levels.
Vitamin K1 and two different types of K2
Vitamin K helps inhibit calcium buildup in your arteries while promoting healthy calcium absorption into your bone matrix.3 K1 is the most common form of vitamin K in the diet, coming primarily from leafy green vegetables—though vitamin K1 isn’t well absorbed from these foods.
Vitamin K2 is found in cheese, eggs and fermented soybeans. It has been shown to be more bioavailable than K1 and to remain active in the body far longer. The MK-4 and MK-7 forms of vitamin K2 also provide important benefits but have different tissue distributions and bioavailability, so it’s important to take both.4,5 This formula contains both forms of vitamin K2.
Vitamin D3 for cognitive, bone and immune health
Healthy serum vitamin D levels have been shown to correspond with better cognitive function.6,7 Vitamin D, along with vitamin K and essential minerals, is necessary for facilitating the transport of calcium into the bone matrix for strong, healthy bones and teeth.8 Vitamin D also plays a critical role in healthy immune function.9
Some people may need 125 mcg (5,000 IU) to 200 mcg (8,000 IU) of vitamin D3 a day to achieve healthy blood levels of vitamin D. If your multivitamin already delivers 25-75 mcg (1,000–3,000 IU) of vitamin D, adding Vitamins D and K with Sea-Iodine™ may help achieve healthy vitamin D levels.
Vitamin D3 for heart health and blood pressure support
Vitamin D promotes a healthy inflammatory response, supports cardiovascular health and encourages healthy endothelial function. Vitamin D also helps inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range.10
Getting enough vitamins D and K and iodine
This vitamin D3 supplement delivers 125 mcg (5,000 IU) of vitamin D3 as cholecalciferol per capsule. We suggest that you take a 25-hydroxy vitamin D blood test after 3 months to assess and adjust your dosage. Your optimal blood levels should be 50–80 ng/ml year-round.
Ensure you get enough of these three essential nutrients with Vitamins D and K with Sea-Iodine™.
