What is Vitamin K2?

Vitamin K2 is not a prominent name that falls in the range of our crucial vitamins and nutrients.

This specific vitamin is an important player in maintaining our health and well-being.

Vitamin k2 is the type of menaquinone that is present in different animal-based foods and fermented foods.

Interestingly, some of the menaquinones are also produced by the gut by good bacteria.

 Vitamin K2 Benefits

Some of the major benefits of using this vitamin K2 include:

#1. Improves Bone Health

Vitamin K2 is indeed the guardian angel of our bones. This works by activating the proteins which helps to manage the calcium.

Furthermore, this vitamin ensures that the calcium gets properly deposited in bones and teeth which makes them strong and resistant.

This lack of vitamin K2 in the body can lead to an increasing chance of osteoporosis and the problem is bone joint health.

Adding to it, if you are an athlete or into bodybuilding, make sure to include enough vitamin K in your diet. This help reduces the risk of bone and joint injury. 

#2. Heart Health

Some researchers have suggested that Vitamin K2 might help in preventing calcium from building up in the arteries, which can be a beneficial side of maintaining heart health.

By keeping the blood flow in the arteries free from any blockage, it can reduce the risk of cardiovascular diseases.

Adding to it, vitamin K2 activates a protein called matrix Gla protein that helps inhibit calcium deposits.

#3. Provides Muscle Building Strength

One may wonder, is vitamin K2 good for bodybuilding?

It helps in regulating calcium metabolism which ensures that calcium is getting deposited in the bone rather than in the muscles.

This can contribute to strong and healthy muscles and reduce the chances of muscle fatigue.

Apart from this, the strong bone serves as a strong foundation for the muscles to develop and therefore enables individuals to go through workout regimes efficiently.

#4. Fights Cancer

Vitamin K2 might have a role in cancer prevention too.

Some studies say that it can prevent the growth of cancer cells and supports creating the body’s natural defense against tumors.

As per the reports of the journal published in Oncology Letters, the combination treatment of vitamin K2 established chemotherapeutics can achieve better results with fewer side effects.

#5. Aids In Blood Clotting

This is among the major benefits of Vitamin K2.

While people are scared of blot clots as they can travel to the brain ad heart and may cause stroke, here, the blot is considered in the sense of injury prevention.

The ability of the blood to clot is what prevents blood loss after an injury and allows it to heal.

You can thank vitamin K2 for this! It keeps the blood clot neither too thick nor too thin.

These are some of the many positive outcomes of vitamin K2 in the body.

Although the benefits are quite promising we must also take a closer look at the side effects it may cause.
