| Niacin is the most common of the "fortified" nutrients in Canada and the United States. The best food sources of vitamin B3 are peanuts, brewer’s yeast, fish and meat, and fortified breakfast cereals. Some vitamin B3 is also found in whole grains. Another source of niacin is the biosynthesis of the amino acid tryptophan. Niacin is one of the most stable of the B-vitamins. This reaction is harmless; it may even be helpful by enhancing blood flow to the "flushed" areas, and it lasts only 10-20 minutes. In addition to flushing, it may cause headache and stomach ache in some people. Larger amounts can cause elevated blood sugar levels, jaundice, liver damage, and elevated blood levels of uric acid and may raise homocysteine levels. Large doses can increase the blood sugar in diabetics, increase risk of gout, and aggravate ulcers. |
