Natural Factors Vitamin B12 Methylcobalamin, 5000 mcg, 60 Chewable Tablets Features : Vitamin B12 is a water-soluble vitamin needed for normal nerve cell activity, DNA replication, and production of the mood-affecting substance SAMe (S-adenosyl-L-methionine). Vitamin B12 acts with folic acid and vitamin B6 to control homocysteine levels. An excess of homocysteine is associated with an increased risk of heart disease, stroke, and potentially other diseases such as osteoporosis and Alzheimers disease. Methylcobalamin is active immediately upon absorption as compared to cyanocobalamin that must first be converted to methylcobalamin by the body. Vitamin B12 aids in the production of red blood cells, which carry oxygen throughout the body. More red blood cells means more oxygen, which may increase your energy levels. Vitamin B12 is found primarily in animal-source foods and may be lacking in strict vegetarian diets. Safe and effective full body cleanse. Natural Factors Vitamin B12 Methylcobalamin provides support for nerve function, energy production and red blood cells.
