What is Vitamin K2 with D3?
New research is focusing on the synergistic relationship between vitamin K2 and vitamin D3, for bone and cardiovascular health.1 A group of naturally occurring and structurally similar, fat-soluble vitamins, vitamin K is essential for the proper utilization of calcium. Through its activation of the protein osteocalcin, vitamin K helps to bind newly absorbed calcium to the mineral matrix in bone. In addition, vitamin K has been found to help maintain bone mineral density by decreasing the activity of osteoclasts, a cell that breaks down the bone matrix.2 Vitamin K also provides critical cardiovascular protection by helping to activate matrix Gla protein (MGP), an enzyme that works by inhibiting calcium from being deposited into the arteries.3,4 Thus, vitamin K and vitamin D not only share similar qualities, but they also act synergistically within the body.5 Vitamin K2 with D3 includes 45 mcg of MenaQ7® PRO, the most widely studied form of vitamin K2 as MK-7, and 5,000 IU of vitamin D3 per capsule for optimal absorption and use by the body.
Overview
While vitamin D has long been known to assist calcium absorption, it is vitamin K, through its carboxylation of osteocalcin, which guides this calcium to bones and prevents their absorption into organs, joint spaces and arteries. Vitamin K occurs in two main forms: K1 (phylloquinone), derived from foods such as green leafy vegetables and K2 (menaquinone), which is a group of related compounds differentiated by their side chains. Numerous studies have shown that vitamin K2 as MK-7 is the more bioavailable form of the nutrient 7 and more powerfully influences bone building than K1. In addition, though both reach the liver, most of the K1 is used for purposes of coagulation, with little left over to support the body’s needs elsewhere.8 The profoundly different degree of bioavailability between K1 and K2 is due to differences in structure: Only 10- 20% of vitamin K1 that is absorbed from food even reaches circulation, while the long side-chain of vitamin K2 allows it to bind with fat particles in circulation and facilitate its arrival at soft tissue, bones and arteries. There are two forms of vitamin K2 commonly used in supplements: MK-4 and MK-7. The MK-7 form has been shown to have six times the activity of MK-4 in the blood.7 MK-7 has also been found to remain in the blood approximately nine times as long as the MK-4 (eight hours versus 72 hours), making it the optimal form of K2 for health.9
The addition of MenaQ7® PRO to this formula is backed by extensive research. Dr. Leon Schurgers, world-renowned expert in vitamin K2 as MK-7 research for cardiovascular and bone health, and his team of research scientists have conducted over 15 clinical trials on MenaQ7® PRO through the University of Maastricht.
Vitamin K Depletion†
Although most people consume adequate dietary vitamin K to maintain sufficient blood clotting, most do not consume enough to meet cardiovascular and bone health needs. In fact, approximately 70% of the western population is deficient in vitamin K2. Compromised intestinal absorption can also lead to insufficient K2 levels leaving calcium available to be exported out of bone and into other tissues. Other medications such as antibiotics, cholesterol-lowering medications and laxatives have also been found to contribute to a deficiency of vitamin K.10
Bone Health†
Building and maintaining healthy bones requires a number of key nutrients including vitamin K, for the proper binding of calcium to the bone matrix. A 2005 study from northern Finland found that those with greater levels of vitamin K-carboxylated osteocalcin had stronger bones than those with lower levels of the protein. A Japanese study found superior bone health among women who were frequent MK-7-rich natto eaters than those who were not.11 Another randomized study which split 172 women into a vitamin K2 group, a vitamin D3 group, a vitamin K2 and D3 group, and a placebo group for two years found that the combination of vitamin D3 and K2 had the most benefits for supporting bone health among the groups.12
Cardiovascular Health and Blood Sugar Balance†
Vitamin K plays a key role in supporting the cardiovascular system as well as blood sugar balance already within normal levels. In a large population study, researchers found that those who consumed high amounts of K2 had significantly better cardiovascular health markers compared to those given vitamin K1.13 Studies have also shown vitamin K supports healthy blood sugar metabolism.14,15 V7 Supplement Facts Serving Size 1 Capsule Servings Per Container 30 & 60
Vit Immune Modulation†
New evidence also suggests vitamin K plays a central role in balancing immune health. Recent studies have shown that both vitamins D and K impart immune-modulating effects. In the Framingham Offspring Study, one of the longest standing studies on generational health, higher serum levels of vitamins D and K were associated with stronger immune function and a balanced inflammatory response.16,17 In a 2011 study, vitamin K was also found to suppress various markers of the immune system.18 Triage Theory The Triage Theory states that in the face of nutrient inadequacies, nature ensures short term survival of a cell is protected at the expense of long-term consequences.20,21 Vitamin K is an excellent example of this theory. Hypothetically, a short-term deficiency in vitamin K would lead to a reduction in blood clotting. This direct threat to survival does not happen, as the body uses its metabolic reserve of vitamin K to ensure immediate needs are met. If continued, this could begin to impact long-term reserves of vitamin K, reserves which are vital for the maintenance of proper bone strength and arterial elasticity. These issues are related to a loss of vitamin K-dependent proteins not required for short term survival, nevertheless presenting long-term health challenges.20

Overview
Magnesium is an abundant mineral in the body and is found naturally in many foods, like green leafy vegetables. It is also found in over-the-counter medications, such as laxatives. The average American intake of magnesium, according to the National Health and Nutrition Examination Survey (NHANES Study) is critically low: Many Americans fail to consume the estimated average requirement (EAR) established by the Institute of Medicine.1 In addition, more than 57% of the population does not meet the United States Department of Agriculture requirements for magnesium in the diet. Intracellular magnesium levels are decreased by excessive intake of alcohol, salt, coffee, phosphoric acid found in sodas, diets high in calcium and high stress levels.2 Because of widespread nature of magnesium deficiencies, adequate daily intake of magnesium is critical for proper hydration, stress response, muscle relaxation, promoting healthy blood pressure levels, optimal bone mineral density, and blood sugar regulation.3,4
Bioavailability – The Mineral Chelate Difference†
The importance of bioavailability is obvious. If consuming a magnesium supplement has little effect on improving the body’s magnesium balance, there is no reason to ingest it. Signs of inferior mineral supplements include the use of cheap, poorly absorbed, rock-salt minerals like calcium carbonate and magnesium oxide (See Figure 1). These mineral forms slow and limit absorption, relying on adequate stomach acid to release magnesium ions which then enter the body via passive diffusion. And, because they tend to remain in the intestines longer, these forms of mineral supplements can cause intestinal distress such as constipation (calcium carbonate) or diarrhea (magnesium oxide).
Magnesium Essentials provides the additional benefit of highly absorbed, Albion® mineral chelates. Albion® is the world leader in manufacturing highly bioavailable mineral chelates, a specialized form of minerals bound to amino acids. This patented process creates organic mineral compounds which use active absorption mechanisms in the gastrointestinal tract to greatly enhance mineral absorption. In a magnesium comparison study reported by Graff et al. at Weber State University, Albion®’s magnesium amino acid chelate had (See Figure 1)5:
• 8.8 times greater absorption than magnesium oxide
• 5.6 times greater absorption than magnesium sulfate
• 2.3 times greater absorption than magnesium carbonate In addition, other comparison studies have shown significantly superior absorption of magnesium chelates compared to other mineral forms:
•At a dose of 400 mg, magnesium chelate significantly reduced or eliminated menstrual abdominal discomfort 6
•Multiple double-blind studies found urinary excretion of magnesium chloride higher than magnesium glycinate, proving superior absorption7-9
•Magnesium glycinate is shown to have a reduced laxative effect when compared to other forms of magnesium10 Mineral chelates are gentle, “gut-friendly” minerals that do not cause diarrhea that often accompanies magnesium oxide and other rock-salt forms. Albion®’s mineral chelates have extensive clinical research proving their superior bioavailability, biologic activity, stability, and improved tolerance.
Heart Health†
Studies to date have found that magnesium supplementation maintains healthy blood pressure levels.11 Calcium is essential to the contraction of muscles, while magnesium aids muscle relaxation. Insufficient magnesium levels can contribute to constriction of the muscles in blood vessels and trigger changes in blood pressure levels. Several prospective studies have examined associations between magnesium intake and heart health. A systematic review and meta-analysis of prospective studies found that higher serum levels of magnesium were significantly associated with enhanced heart health and optimized blood flow to the heart.12
Insulin Balance†
Magnesium is integral for the transport of insulin from the bloodstream to cells. Increasing magnesium levels has been shown to maintain normal blood sugar levels. Diets with higher amounts of magnesium are associated with blood sugar balance, due to the role of magnesium in glucose metabolism. 13-15 Most investigations of magnesium intake and insulin balance have been prospective cohort studies. A meta-analysis of seven of these studies, which included 286,668 patients, found that a 100 mg/day increase in total magnesium intake promoted insulin balance by a statistically significant 15%.10 Another meta-analysis of eight prospective cohort studies that followed 271,869 men and women for an extended period of time found a significant association between magnesium intake from food and insulin balance.16
Bone Health†
Magnesium is involved in bone formation and influences the activity of osteoblasts and osteoclasts, cells responsible for the breakdown and formation of bone.17 Magnesium also impacts concentrations of parathyroid hormone and the active form of vitamin D, which are major regulators of bone homeostasis. Several population-based studies have found positive associations between magnesium intake and the state of bone strength and mineralization in men and women.18-19
