  • MK-7 vitamin K2 60tabs Protocol for Life Balance

    Vitamin K is well known for its role in blood clotting, but has also been found to play an important role in normal bone formation and the preservation of bone strength. Vitamin K2 more specifically is a significant regulator of tissue calcification and is critical for the maintenance of arterial elasticity and cardiovascular health. Vitamin K2 includes two of the most studied subtypes, MK-7 (Menaquinone-7) and MK-4 (Menatetrenone). MK-7, the most readily absorbed and bioactive form of K2, has no common dietary sources. Unlike Vitamin K1, which is stored in the liver, MK-7 is transported directly to tissues and has a longer half-life than either K1 or MK-4.• Supports Bone Health• Supports Vascular ElasticityServing Size: 1 TabletServings Per Container: 60Amount Per ServingVitamin K2 (as Menaquinone-7) (MK-7) (from Natto) (soy) 160 mcgOther Ingredients:Natto (soy), Cellulose, Magnesium Oxide, Stearic Acid (vegetable source), Silica, Magnesium Stearate(vegetable source), Vegetarian CoatingSUGGESTED USAGE: As a dietary supplement, take 1 tablet 1-2 times daily with a fat-containing meal or as directed by your healthcare practitioner.Not manufactured with wheat, gluten, milk, egg, fish, shellfish or tree nut ingredients.

Vitamin K supplements help in maintaining proper blood clotting factors, keeping bones healthy and helping ward off a wide variety of illnesses and problems for people of all ages. Vitamin K is a fat soluble vitamin that comes in two naturally occurring forms: K1 and K2. Vitamin K1 can be found in many foods. Vitamin K2 is produced within the large intestine by intestinal bacteria. There are also synthetic forms of vitamin K (K3, 4 & 5) which are used medicinally. Vita Living offers Allergy Research Group Full Spectrum Vitamin K, Life Extension Super K and an impressive selection of strengths, forms and combinations of K vitamin supplementation.

Although medical professionals sometimes say that people are not likely to suffer a shortage of vitamin K because it is produced by the body, it is important to remember that it is only vitamin K2 that is produced by the body. Additionally, this process can be interfered with by improper diet, long term antibiotic use, liver disease and other circumstances. For this reason, it is a good idea to supplement natural vitamin K1 and to maintain a healthy diet that includes green, leafy vegetables, cruciferous vegetables such as cabbage, cauliflower and broccoli, and fruits such as grapes, kiwi and avocado. Parsley is especially high in vitamin K1 and should be included in the diet on a regular basis. In addition to supplementation, good natural sources of vitamin K2 include dairy products, eggs, meats and a fermented soybean food source known as Natto. Avoiding vitamin K deficiency amounts to avoiding such problems as excessive bleeding, osteoporosis and cancer. Additionally, a proper balance of vitamin K helps regulate metabolism and assist in proper production and use of insulin. For this reason, regular use of a high quality vitamin K supplement is highly recommended for optimum health. If you are taking blood thinners, please consult your physician before taking Vitamin K since it also acts as a natural blood thinner.
