Vitamin B12 is an essential water-soluble nutrient for the normal function of many systems of the body, as well as DNA and RNA synthesis and red blood cell production. Vitamin B12 plays an important role in neurological function, mood and memory, bone health, and fetal development. B12 is a necessary cofactor for the metabolism of homocysteine into methionine, and the subsequent formation of the universal methyl donor S-adenosylmethionine (SAMe) from methionine. Vitamin B12 deficiency leads to the development of elevated homocysteine levels, which is a well-recognized risk factor for cardiovascular disease, and may be associated with an increased risk of cognitive decline.

B12 deficiency is more common with age, hypochlorhydria, small intestinal bacterial overgrowth, gastrointestinal bypass surgery, alcohol use, following a vegetarian or vegan diet, and use of medications such as proton-pump inhibitors, metformin, and hormonal contraceptives. Serum levels of B12 have been shown to poorly reflect tissue deficiencies, and elevated methylmalonic acid and total homocysteine levels have been seen in the majority of patients who experience a clinical response to vitamin B12. Methylcobalamin is the active form of B12 that is necessary for homocysteine metabolism, and as a methyl donor supports normal healthy function and the body's detoxification processes.

Key features

Our Quicksilver Delivery Systems improve upon liposomal and emulsification technology with smaller, more stable particles made from the highest-grade ingredients available. In addition to exceptional absorption rates, these very small liposomal and nanoemulsified particles enhance lymphatic circulation of nutrients and intracellular delivery. The phospholipids, inherent in the liposomal and nanoemulsified formats, nourish cell membranes, promoting proper function for the absorption of nutrients and the excretion of cellular waste products and toxins.
