Consider three nutrients that may be lacking: vitamin D, iodine, and vitamin K. This time of year, in particular, your vitamin D levels could be too low. Though sunlight exposure causes your body to manufacture the nutrient, it occurs less than we need it to in winter. Besides, unprotected skin exposure to the sun’s rays can be harmful. Iodine is a trace element essential for the production of thyroid hormones. Common table salt has long been fortified with iodide to make up for the loss in our diets. Individuals who reduce daily salt intake, and therefore iodized salt, may find that their thyroid suffers. Lastly, vitamin K (MK-4 and MK-7 ) is an essential nutrient that promotes both arterial and bone health.
Iodine is a trace element necessary for the production of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). Iodine is abundant in seafood, eggs, cranberries, and sea vegetables, but not everyone likes or has access to enough iodine-rich foods. Consequently, vegan diets sometimes lack adequate iodine. How much fish and seaweed do you get? Not only do many people often not enjoy seaweed, but vitamin K from these sources may be poorly absorbed. In fact, thyroid cells are the only cells in the body that can absorb iodine. Make sure you’re not deficient.
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 2 Different Types of K2
Vitamin K helps inhibit calcium buildup in your arteries while promoting healthy calcium absorption into your bone matrix. K1 is the most common form of vitamin K in the diet, coming primarily from leafy green vegetables like kale—though vitamin K1 isn’t well absorbed from these foods. Blood clotting is primarily affected by this particular form of the vitamin.
In contrast, vitamin K2 is found in certain cheeses, 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 get both.
Vitamin D3 – Cognition, Bones, and Immunity
Healthy serum vitamin D levels have been shown to correspond with better cognitive function. 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. Vitamin D also plays a critical role in healthy immune function.
Some people may need 5,000–8,000 IU of vitamin D3 a day to achieve healthy blood levels of vitamin D. If your multivitamin already delivers 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 – Heart Health and Blood Pressure
Vitamin D promotes a healthy inflammatory response, supports cardiovascular health and encourages healthy endothelial function. It also helps inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range.
Dosage – Vitamins D and K and Iodine
You could get 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 one of these supplements:
- Sea–Iodine™ – 1000 mcg iodine from a complex blend of organic kelp and bladderwrack extracts, with potassium iodide
Super K – a combination of vitamin K1 with two types of vitamin K2: MK-4 and MK-7
- Vitamins D and K with Sea-Iodine™ – all three nutrients combined (including MK-4 and MK-7 form K2)
