I’m happy to comment on this interesting topic! Vitamin K is a term attached to a family of similar but slightly different compounds. Therefore, vitamin K1 (phylloquinone) and several types of vitamin K2 (menaquinone) are collectively called “vitamin K”. You can also read about the various forms of vitamin K2, MK-4, MK-7 or MK-9. This is all the chemistry we need now.

Vitamin K has historically been known as a “coagulant vitamin” because it plays an important role in coagulating blood. In fact, a typical symptom of vitamin K deficiency is abnormal bleeding.

Recently, research has been conducted on the role of vitamin K in bone health. Vitamin K1 and K2 are both involved in the process of increasing bone strength, but vitamin K2 appears to be the most protective in this particular task. Vitamin K K2 deficiency is associated with osteoporosis (fragile bone) and arterial calcium deposition (commonly referred to as arteriosclerosis).

The current recommendations for proper intake of vitamin K over the age of 19 are 90 micrograms (mcg) for women and 120 mcg for men. This includes both K1 and K2 forms.

Due to its new role in bone and heart health, some researchers now believe that vitamin K requires its own recommended daily requirements. Also, it is not yet clear whether to take K2 supplements.

One year later, the most effective dose for reducing bone loss in the femoral neck (hip) of postmenopausal women is 90 micrograms (mcg) daily with or without the addition of calcium or vitamin D3. ) Turned out to be.Interestingly no change Bone health Discovered in men in this study.

At this time, it is best to include a dietary source of vitamins K1 and K2 in your diet. And their sources are different.

Vitamin K1 is abundant in leafy vegetables such as broccoli and spinach. Vitamin K2 is found in fermented foods (especially natto and fermented soybeans), cheese, egg yolks and meat (especially liver).

Why animal food? According to experts, animals have a unique ability to synthesize vitamin K2. vitamin K1 comes from the grass.
