🧪 Formulation Notes

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. In addition, B12 is involved in DNA synthesis and renewal. This formulation provides high potency vitamin B12 in a convenient nugget form that is also suitable for vegans.
