It can be found in meats and fermented products, such as cheese and natto, which is an ancient Japanese food – a fermented soybean food. However, not many people readily eat fermented foods, and when vitamin K1 is consumed through green, leafy vegetables, studies have suggested that just about 10-15 percent get absorbed.
One of the inherent problems with vitamin K is that, unlike tests for vitamin D, there is not as accurate of a test out there now to determine how much of this nutrient is actually absorbed in the body. However, the potential advantages of vitamin K are great. It promotes heart health, protects and supports the skin, provides the calcium path from your bloodstream to your bones and can boost your overall immune system, among other things.
For purposes of this article, evidence supports the theory that vitamin K plays a pivotal role in bone metabolism and healthy bone growth. Vitamin K has been linked to osteoblasts, which are the cells that generate bone, producing the protein osteocalcin, which is more or less the framework that holds the calcium in place in the bones. Without vitamin K, osteocalcin cannot do its job effectively.
In short, vitamin K is what allows the calcium in your bloodstream to flow into your bones and bone marrow. Without vitamin K aggressively at work in your body, your bones would not have the strength that they need. Vitamin K has been shown to help maintain your bones.
In short, there are a host of articles and studies on the web that speak to vitamin K and its role in bone health. Admittedly, many such articles are steeped in deep medical terms that go beyond my own comprehension. However, I wanted to shed some light on what some have coined as the “forgotten vitamin.” Please make sure to do your research as to what forms are safe and what forms should be avoided. After all, knowing that vitamin K has a significant impact on our bone health, why should calcium and vitamin D get all the attention?
