Additional Information

Vitamin B12 is part of a group of essential nutrients known as the B Complex. It supports energy metabolism and promotes a healthy nervous system. Along with folic acid and vitamin B6, it supports heart health by promoting healthy levels of homocysteine already within a normal range. B12 is required for the normal development and regeneration of red blood cells, which help to deliver oxygen throughout the body.
