Isotonix Vitamin D with K2 contains vitamin D3, the metabolically active form of vitamin D, along with vitamin K2, a form of vitamin K which supports cardiovascular health. Vitamin D plays an important role in bone health and immune health while working with vitamin K to support the absorption of calcium. Isotonix Vitamin D with K2 is to deliver both these great vitamins with isotonic delivery.

Vitamin K is included in Isotonix Vitamin D with K2 because of its unique partnership with vitamin D. Vitamins K and D work together to support calcium absorption and the delivery of calcium to the bones.

At least two naturally occurring forms of vitamin K have been identified and are known as K1 and K2. While there are many similarities between these two forms of vitamin K, they are distinguished by their important differences. The most significant difference between K1 and K2 is their chemical structures which provide for different pharmacokinetic properties.



Vitamin D3 (Cholecalciferol)
Vitamin D is a lipo-soluble vitamin that is found in some foods and endogenously produced when sunlight strikes the skin and activates vitamin D synthesis. Vitamin D promotes the efficient absorption of calcium. Vitamin D also promotes the formation of bone and growth. Lack of exposure to sunlight, reduced skin synthesis of vitamin D, lower dietary intake, impaired intestinal absorption, and ageing may reduce the amounts of vitamin D in the body. In addition to promoting strong bones, vitamin D also has other roles in health including supporting the body’s muscular function and immune health.

Vitamin K2
Vitamin K is a lipo-soluble vitamin found in meat, eggs and dairy. The Japanese soy food natto is particularly rich in menaquinone-7 (MK-7). Studies of natto consumption in Japan have linked menaquinone-7 to bone and cardiovascular health. The correlation of vitamin K to cardiovascular and bone health directly focuses on supporting proper calcium utilization. Vitamin K2 promotes the synthesis of proteins involved with calcium utilization, thereby supporting bone mass.

Revised my backache

I was having a prolong backache and during a routine blood test, I found out that my vitamin D was at borderline. After I started consuming Vitamin D for about a month, my Vitamin D level went back to normal range and my backache was gone too.
