A number of trials have shown that the combination of K2 and vitamin D3 is more effective in preventing bone loss than either nutrient alone.
Vitamin D3 and Vitamin K2 (MK-7) deficiency is a worldwide epidemic. Over 1 billion people are at risk for its associated conditions beyond just this winter’s viral concerns. Almost daily, references to vitamin D dominates the headlines. Paradoxically, very little is being said about Vitamin K2. However, there is overwhelming evidence confirming that the safety of vitamin D is dependent on adequate vitamin K2 (MK-7).
K2 has been reported to decrease serum cholesterol and cholesterol deposits in the aorta, contributing to the suppression of atherosclerosis.
It is recommended that “Adults at higher risks of having lower levels of Vitamin D should consider taking a Vitamin D supplement of 1000 IU/day all year round.” The best form of Vitamin D3 (cholecalciferol) is derived from the lanolin in sheep’s wool and should be free of Vitamin A.
Fat-soluble Vitamin D3 is converted by the kidneys into the hormone calcitriol, the activated form of Vitamin D3 which affects a variety of target tissues including bone, intestine, muscle, brain, skin and immune system cells.
Calcitriol enhances calcium and phosphorous absorption and stimulates the synthesis of osteocalcin, an important structural protein in bone. Calcitriol is also involved in proper cell differentiation (changing of cell function), including prostate, breast and colon cells.
