Description: It is important to remember that this nutrient has nothing to do with nicotine in tobacco. Vitamin B3 is needed to produce enzymes that are involved in the reduction/oxidation reactions in the metabolism of carbohydrates, proteins, and fats. A vitamin B3 deficiency can lead to pellagra which can lead to digestive problems such as diarrhea, skin problems and dementia. Also, this deficiency disorder can be fatal if it goes untreated. Supplementing with this vitamin in the form of niacin can cause flushed skin and discomfort because niacin is a vasodilator. Also, supplementing with doses of over 60 times the normal fortification level is not recommended.
