B3-Niacin

Niacin.  There is so much information on Niacin, there are entire books written about this miraculous vitamin.  It was first isolated during oxidation of nicotine from tobacco.  It is not the same or even close to the molecule nicotine. Niacin is one of the most stable B vitamins, resilient to heat, light, air, acid and alkali.  Niacin is absorbed in the small intestine and small amounts are stored in the liver, but most of the excess is excreted in the urine.   Another important fact about niacin is that it can be manufactured in the body from the essential (meaning it needs to be obtained in the diet) amino acid tryptophan.  If enough protein is being consumed, supplementation isn’t needed.   When we are deficient in vitamins: B1, B2, and B6, Vitamin C and iron, our body can’t convert tryptophan into niacin.
It is responsible for many functions in the body including:

• Functioning of the nervous system
• Metabolism of carbohydrates, fats and proteins
• Production of Hydrochloric acid
• Involved in normal secretion of bile and stomach fluids
• Lowers cholesterol
• Improves circulation
• Enhances memory

Deficiencies signs:

A cup of coffee has about 3 milligrams of niacin, yet another reason to reach for that cup of Java in the morning!
