Essential for the correct functioning of all cells, especially bone marrow and nervous tissue, it is also required for red blood cell formation.
Vitamin B12 is needed for normal nerve cell activity, DNA replication, and
production of the mood-affecting substance called SAM (S-adenosyl methionine).
Vitamin B12 works with folic acid to control homocysteine levels. Excessive
homocysteine, which is an amino acid (protein building block), increases the
risk of heart disease and perhaps osteoporosis.
Necessary for normal digestion, absorption of foods, proteins synthesis and carbohydrate and fat metabolism. Found in liver, kidney, meats, fish, dairy products and eggs.
