Niacin, also called vitamin B3, is required by all the cells of our body making it essential for vitality and life itself.
Niacin is essential for keeping our skin and digestive tract healthy, our brain and nervous system functioning normally, certain key cell processes repaired, our adrenal glands producing steroid hormones at demand levels, sex glands producing the hormones estrogen, progesterone and testosterone and, most especially, for producing energy to keep our body alive.1
When absorbed from the small intestinal tract, niacin becomes part of a process including more than 200 enzymes involved in metabolism of carbohydrates, proteins and fatty acids, that is, chemical reactions that maintain life.1 Niacin is stored by the liver.2
Niacin must be digested to release its absorbable forms, nicotinamide and nicotinic acid. These molecules are absorbed across the intestinal lining at low concentrations by sodium-dependent facilitated diffusion, meaning they need help to get into the bloodstream.1 (more…)
