Vitamin B12 (500mcg)
This essential vitamin helps form red blood cells that deliver oxygen to all parts of the body, which in turn promotes energy. It also supports cardiovascular health by working with vitamin B-6 and folic acid to help neutralize harmful homocysteine. While adequate B-12 intake is important for everyone, supplementation may be particularly helpful for some people because the vitamin is found primarily in animal-based foods.
Recommended vitamin for those who eats high amount of meat and women who takes contraceptive tablets.
You can enhance the effectiveness of B-12 if you take C-vitamin, tiamin, riboflavin and magnesium as well.
