With Methylcobalamin B12 you get a blend of B vitamins that include Folic acid, B6 and B12. You get all these nutrients straight into your blood stream and it helps with nervous system functions as well as the cardiovascular system.

This is called a "Sublingual" type of vitamin supplement. What this means is that this product goes past your digestive system so that nothing is wasted and all the B vitamins can safely get into your bloodstream. It is very nice as you age because when you get older your body can't absorb nutrients as well. This counters that problem. The Vitamin B-6 and Folic Acid components of Methylcobalamin B12 also help reduce the levels of serum homocysteine and raise the health of your nervous system. One of the risk factors for a heart attack includes high levels of homocysteine. The amount of people that have high levels of this substance are prevalent in all patients with heart disease. 

The main reason why high levels of homocysteine can be dangerous is because it causes plaque to build up in the blood and arteries. The common cause of this process taking place is the lack of vitamins like B-6, B12, and Folic Acid. It is easy to become deficient in this if you eat a lot of processed food.
