    • Best absorbed & non-toxic form of supplemental Vitamin K
    • A factor in reducing risk of bone fractures
    • An important nutrient for heart & arteries

    Build Strong Bones!

    Made from Menaquinone 7 (MK-7), this is the best-absorbed & non-toxic form of supplemental Vitamin K 2. Our bodies need vitamin K as a co-factor with calcium to build bone. Researchers found that people who have higher levels of vitamin K have greater bone density, while low levels of vitamin K have been found in those with osteoporosis. There is increasing evidence that vitamin K improves bone health and reduces risk of bone fractures, particularly in postmenopausal women who are at risk for osteoporosis. In addition, studies of male and female athletes have also found that vitamin K helps with bone health. Vitamin K2 is also an important nutrient for heart and arteries, supports immune health and is essential to adequate blood coagulation.

    Prevent Drug-Induced Vitamin K 2 Deficiency

    Medications that can lower Vitamin K2 levels in the body include*: Antibiotics (especially cephalosporins), anticonvulsants (such as phenytoin), Orlistat (Xenical, Alli) and Olestra (for weight loss), bile acid sequestrants (to lower cholesterol).

    Bones
    The combination of vitamins K and D has been shown to significantly increase bone mineral density (BMD) better than either alone. High-dose vitamin K has been shown to significantly reduce fractures in double-blind research of postmenopausal women with osteopenia. A review of seven controlled studies confirmed that high-dose vitamin K reduces the risk of fractures, and large amounts of vitamin K have been shown in preliminary research to correlate with greater BMD and to increase bone formation in some women. MK-7, the form of vitamin K in Vitamin K2+A+D3 has been shown to increase bone mineralization, to significantly reduce loss of BMD, improve bone strength and decrease risk of fracture in placebo-controlled research. K2 has also been shown to improve the ratio of bone formation to bone breakdown. A meta-analysis of thirteen controlled studies found that long-term high-dose vitamin K supplementation reduces bone loss.

    Vitamin D has also been shown to increase bone density and to reduce hip fracture by 43-60%.

    Eyesight & Night Vision
    Vitamins D and A benefit the eyes. People with the highest vitamin D levels are 36% less likely to have macular degeneration. Vitamin A deficiency may cause, and supplementation may improve, night blindness. Doubleblind research shows that high-dose vitamin A can speed up recovery of light sensitivity and adaptation to dark.

    Skin
    Vitamins D and A are also good for your skin. Vitamin D can help adults with low levels of D and children treat eczema, and high-dose vitamin A has been shown to prevent acne.

    Teeth
    Vitamin K supports activation of proteins involved in tooth mineralization. People with the highest levels of D have 30% less risk of gingivitis. Vitamin D also helps periodontal disease because men with the highest levels of D have 39% less bone loss and women have 26% less: supplementation with vitamin D reduces bone loss.

    Immunity
    In people who are deficient in vitamin A, supplementing vitamin A can enhance immunity. Impressively, vitamin D reduces the risk of flu in kids by 42% during the winter.

    Vitamin K regulates calcium and blood clotting in the body. It helps maintain healthy teeth and bones and promotes cardiovascular health by inhibiting calcium accumulation in the arteries. It is also a powerful antioxidant. Vitamin K naturally occurs in two forms: Vitamin K1 and Vitamin K2. Clinical studies on Vitamin K2 have shown that it reduces and prevents fractures and increases bone density. Vitamin K2 is necessary to activate proteins that are involved in the utilization of calcium – both for building strong bones and inhibiting calcium accumulation in the arteries.

    Vitamin K2

    Menaquinone-7

    DESCRIPTION

    Vitamin K2, provided by Douglas Laboratories®, supplies a significant amount of biologically active vitamin K in the form of menaquinone-7 (MK-7).

    This product is soy free.

    FUNCTIONS

    Vitamin K was originally discovered as the anti-hemorrhagic factor, but it now encompasses a variety of physiological processes. The major source of vitamin K in most diets is phylloquinone (vitamin K1), which is present in green leafy vegetables such as spinach, broccoli, and kale. Vitamin K2 is present in small amounts in fermented foods, milk products, cheese, and meat, and is synthesized by various human gut microbiota. It is well documented that the Western population obtains insufficient vitamin K from their regular diets, possibly related to poor absorption from these foods. Beyond blood clotting, the role of vitamin K in osteoporosis and cardiovascular disease is related to calcium utilization. Scientific studies have revealed that vitamin K plays a crucial role in building and maintaining bone health, which is influenced by osteoblasts, osteoclasts, hormones, cytokines and nutritional factors, including vitamin K intake. Inadequate calcium metabolism can result in cardiovascular and bone health problems. The deposition of calcium into arteries is an organized, regulated process similar to bone formation that occurs when other factors are present. Proteins like osteocalcin and matrix Gla protein, which are actively involved in the transport of calcium out of vessel walls, are suspected to have key roles in coronary calcium deposition. The greater the amount of calcification, the greater the likelihood one may develop suboptimal coronary health. Additionally, research shows undercarboxylated osteocalcin and low vitamin K intakes are risk factors for fractures in women. Vitamin K is needed to activate osteocalcin (carboxylated), which functions to take calcium out of the vessels and deposit them into the bones. Therefore, consuming sufficient amounts of dietary calcium is not enough for bone and cardiovascular health; the body needs to distribute and utilize the calcium properly with aid of Vitamin K.

    Vitamin K2 (as MK-7) is more bioactive and has proven more effective than vitamin K1 and other menaquinones. MK-7 showed eight times the half-life of vitamin K1 in a 24-hour serum concentration level after 1 mg of each form was ingested. Thus, MK-7 can be administered in low dosages only once a day, typically 1/1000 that of a MK-4 dose. Furthermore, the study showed better utilization and improved osteocalcin carboxylation for MK-7 after 6 weeks. Numerous studies reveal long-chain menaquinones, such as MK-7 are more effective in supporting arterial health than vitamin K1 menaquinones. Douglas Labs’ Vitamin K2 as menaquinone-7 (MK-7) is derived from geraniol and farnesol. Geraniol is the primary part of rose oil, palmarosa oil, and citronella oil. Farnesol is present in many essential oils such as citronella, lemon grass, rose, and musk. This natural form of MK-7 has been extensively tested for molecular identity and bioequivalence when compared to MK-7 from fermented soybeans (natto). It is the all-trans form, thus providing a significantly higher purity of the only biologically active form.

    INDICATIONS

    Vitamin K2 may be a useful dietary supplement for individuals who wish to increase their intake of Vitamin K and support bone and cardiovascular health.

    Overview

    Natural Factors K &D provides two major fat-soluble vitamins for bone and vascular health; bioactive and highly bioavailable D3 (cholecalciferol), and menaquinone-7 (MK-7) from natto bean. Both vitamins act on calcium and guide the mineral towards where it is needed throughout the body.

    Advanced Info

    An important fat-soluble vitamin, vitamin K2, plays critical roles in protecting the heart and brain, as well as building strong bones. As a director of calcium, vitamin K2 guides the mineral towards tissues where it is needed, such as in bones, and away from tissues where it could have a negative effect, such as arteries. Natural Factors vitamin K2 is highly bioavailable menaquinone-7 (MK-7) from the natto bean, which offers 24-hour benefits from a single daily dose.

    Vitamin D is also a fat-soluble vitamin that is essential for calcium absorption, playing an important role in the growth and maintenance of healthy bones and teeth. Ongoing and current research outlines the importance of vitamin D in the prevention of osteoporosis. It aids calcium absorption from the intestines, reduces calcium excretion, and facilitates calcium incorporation into the bones. Vitamin D3 (cholecalciferol) is the safe, natural, and more biologically active form of vitamin D.

    Natural Factors K &D provides the ideal ratio of two major fat-soluble vitamins for overall health, and support of bones and vascular health.

    Vitamin K is well known for its role in the synthesis of a number of blood coagulation factors. During recent years however, Vitamin K2 and its dependent proteins have been found to play a central role in whole-body calcium metabolism. These Vitamin K2-dependent proteins are now known to be essential for normal bone mineralization, as well as for other critical functions unrelated to coagulation. NOW® MK-7 contains a highly biologically active form of Vitamin K2 derived from non-GMO natto, a traditional Japanese fermented soyfood.

    Vitamin K2

    100 mcg

    60 Vegetarian Capsules (SKU 1294)

    Overview

    Researchers have finally uncovered the connection between lack of calcium in the bones (osteoporosis) despite having an excess of calcium in the arteries (atherosclerosis). Vitamin K2 is behind this Calcium Paradox. With vitamin K2, calcium is guided towards the areas of the body where it is needed, such as the skeleton, and away from areas where it could have a negative effect, such as the cardiovascular system.

    Advanced Info

    Natural Factors Vitamin K2 features vitamin K2 as menaquinone-7 (MK-7), an advanced, fat-soluble form of vitamin K that serves multiple functions in the body. The K family consists of a trio of vitamins: K1 (phylloquinone), naturally occurring in leafy green vegetables and plant oils; K2 (mena-quinone) present in butter, cows liver, eggs, certain cheeses and natto, a fermented soybean food; and K3, a synthetic form of the vitamin. K3 has been shown to have toxic effects on the liver and K1 doesn’t have adequate benefits for calcium metabolism to dramatically improve osteoporosis or atherosclerosis. Only K2 in the form of MK-7 has been shown to offer 24-hour protection from a single daily dose. Other commercially available subtypes of K2, such as MK-4, only last four to six hours in the body and are required in much larger dosages to be effective.

    Vitamin K1 is easy to obtain from green leafy vegetables. The bacteria in our intestines will convert some of that to K2, but not enough to prevent or treat atherosclerosis and osteoporosis. K2 is found in the diet in natto, a fermented soybean food popular in Japan, as well as in butter, meat, egg yolks, and organ meats from animals that are fed grass instead of grain. As grass-fed animal products are rare nowadays and a taste for natto is difficult to acquire for most Westerners, a vitamin K2 supplement is the best way to ensure you are getting an optimal daily dose of this important nutrient.

    Researchers worldwide are only beginning to uncover the many essential roles that vitamin K2 plays in our health. Our growing understanding of this nutrient is rapidly redefining cardiovascular disease as an illness of nutritional deficiency. In addition, a vitamin K2 deficiency appears to be an underlying factor in the development of diabetes and liver cancer. Vitamin K2 also plays an essential role in bone metabolism and promoting healthy teeth. For most people, diet alone will not help them meet their daily requirement of vitamin K2. Daily use of Natural Factors Vitamin K2 makes it easy to get optimum levels of this important nutrient.

    Although Vitamin K is historically known for its role in normal blood clotting function, we now know that Vitamin K is also essential to bone, cardiovascular, and nervous system health. As a biologically active form of Vitamin K, K-2 is important for the formation of healthy, strong bone matrix. Vitamin K's role in arterial health revolves around its ability to support proper calcium metabolism in vascular structures.

    Many Canadians are plagued by a lack of calcium in their bones, leading to osteoporosis and yet many of us suffer from excess calcium in our arteries, leading to atherosclerosis or hardening of the arteries. The co-occurrence of these seemingly contradictory conditions is known as the “calcium paradox”.1 Medical research has established the connection between bone calcium loss and atherosclerosis in individuals with osteoporosis, those with kidney disease and in the general population.1 In fact, it has been shown that for every 1.5% decrease in bone density the mortality risk from cardiovascular disease increases by 30%.2 More and more research is showing that vitamin K plays an essential role in the prevention of the calcium paradox, helping to ensure that calcium gets to the right place in the body!3

    Two Important Forms of Vitamin K2 for Bone Health

    • Helps your bones use calcium more effectively
    • Supports normal blood clotting and cardiovascular health
    • Provides both MK-4 and MK-7 for greater effectiveness

    Vitamin K2 from AOR™ now provides MK-4 and MK-7, two natural forms of Vitamin K2 that help maintain bone health. Although it interferes with "blood thinning" medications, it does not cause excessive or abnormal blood clotting.

    Vitamin K is an essential vitamin needed for cardiovascular, bone and liver health. Vitamin K2 is more effective than vitamin K1, the form found in plants, for these specific health effects. There are two effective and popular forms of Vitamin K2: namely MK-4 and MK-7. While MK-4 is the active form of vitamin K2 used by the body and has been used clinically in Japan for decades with good results, MK-7 has also been shown to provide good results at low doses in a sustained-release manner. AOR’s Vitamin K2 provides a 50/50 blend of MK-4 and MK-7 to ensure the best of both worlds.

    The most popular, albeit recently highlighted, use for vitamin K2 is for bone health. Vitamin K, along with vitamin D, is essential for proper calcium absorption and usage in the bones. Vitamin K2 also stimulates the synthesis of proteins that regulate bone growth, and has been shown to reduce the incidence of osteoporotic fractures and improve bone quality.

    Vitamin K is also essential to cardiovascular health. It is an important blood clotting factor: without adequate amounts, the risk of bruising and excessive bleeding increases substantially. By the same token, vitamin K enhances calcium absorption from the bloodstream into the bones, preventing arterial calcification and promoting healthy blood vessel function and heart health. Ultimately, Vitamin K2 is an excellent adjunct to conventional osteoporosis medications and is essential for those taking calcium supplements. Vitamin K2 may also be useful for those with a family history of osteoporosis, cardiovascular disease, arterial calcification or for people who bruise or bleed easily.
