Vitamin K₂ or menaquinone is one of three types of vitamin K, the other two being vitamin K₁ and K₃. K₂ is both a tissue and bacterial product and is usually found in animal products or fermented foods.

Vitamin K2 is good for heart health
Vitamin K2 helps to direct calcium to the bones and prevent it from being deposited where it shouldn't be, for example arteries and organs, where it can cause harm.8 According to The Rotterdam Study research, in which men were studied for more than 15 years, the highest intake of Vitamin K2 was linked with a lower risk of heart-related issues, including cardiovascular disease, and cardiovascular disease mortality.9

It’s good for bone health
Vitamin K3 activates the proteins that help regulate calcium deposition. This means that it supports the calcification of bones and prevents calcium deposits from forming in the blood vessels.10 A study of Japanese postmenopausal women, who ate Natto, found that they experienced lower bone loss over time.11

And dental health too
Due to the fact the protein that’s needed to build strong teeth, osteocalcin, is the same one activated by Vitamin K2 to regulate bone calcification. However, it’s important to flag here that research in relation to this particular benefit is limited at present.12 (For more information about the fundamentals of dental health, have a read of this, ‘Calcium and dental health.’)

Summary
Several health benefits have been linked to Vitamin K2. They range from helping prevent heart disease and maintaining healthy bones, to building strong teeth.

While evidence of the impact of having too much Vitamin K in our systems remains limited right now, it’s still important you make sure you don’t exceed the recommended daily intake levels.

The NHS says it’s important, and possible, to get sufficient quantities of Vitamin K by eating a healthy and balanced diet that contains food sources, such as those listed above.17

Being deficient in Vitamin K is a rare thing, but if your levels are depleted, then it is possible to take a supplement to help increase them. Vitamin K is also available in supplements that contain just Vitamin K or Vitamin K combined with other nutrients, such as calcium, magnesium, and/or vitamin D.18

The most common types of Vitamin K supplements are:

1. Phylloquinone and phytonadione (AKA Vitamin K1)

2. Menaquinone-4, and menaquinone-7 (AKA Vitamin K2).

One of the biggest vitamin K2 side effects on health is its potential to interact with blood-thinning medications. Blood-thinning medications work by inhibiting vitamin K. Suddenly increasing the vitamin K2 coming from any source, whether vitamin K2 supplements or vitamin K2-rich foods, may decrease the effect of blood-thinning medications. Cutting down on vitamin K2 may increase its effect. This unwanted side effect may seem more significant with vitamin K2 than vitamin K1. Even a small change in menaquinone intake may affect anti-coagulant medications.

When an allergic reaction turns up, vitamin K2 supplements are basically safe and non-toxic. Menaquinones may be metabolized with vitamin K2 differently than vitamin K1. For instance, vitamin K2’s effect coming from fermented foods on blood-thinning medications may last longer than vitamin K1’s effect.

This is actually one of the common side effects of vitamin K2 that you should know and try to be cautious when taking in vitamin K2 from any sources while taking blood-thinning medications.
