Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a major role in various aspects of human physiology. It acts as a cofactor (or “helper molecule”) in the metabolism of fatty acids, such as those used for
nerve myelination, the metabolism of homocysteine (a molecule associated with cardiovascular health), and the synthesis of nucleic acids. Nucleic acids are required for every dividing cell in the body, especially red blood cells and the
cells of the gastrointestinal tract.
Since it can’t be created naturally by your body, you have to rely on your diet and supplements to ensure adequate levels of vitamin B12. The only natural sources of the vitamin are animal products, such
as liver, eggs, meat, fish, and milk. The elderly are at particularly high risk of developing vitamin B12 deficiency, as are people suffering from certain gastrointestinal diseases that inhibit nutrient absorption.
deficiency can deplete your body’s supply of red blood cells, affect cardiovascular and neurological health, and leave you feeling weak and constipated. That’s why taking a supplement like Progressive Labs’ B-12
