History

Pellagra used to be a common disease among communities where corn was a staple. People would suffer diarrhea, dermatitis and dementia. Finally, death resulted. After centuries of bewilderment over a cause of disease, Goldberger discovered that nicotinic acid (niacin) cured pellagra in dogs. Corn prevents the absorption of niacin in the intestines. However, the typical American diet supplies more than enough niacin to meet daily needs.

The Recommended Daily Intake of Niacin is 18 mg. Niacin side effects may result from doses larger than 150 milligrams. Niacin flush, itchy skin as well as liver disease may result from long-term overdose. However, serious side effects may not begin to occur until after doses of 2000 to 6000 mg.

Niacin Effects

Niacin has a cholesterol-lowering effect. Many studies have pointed out that niacin has a significant impact on total cholesterol. People who have ulcers or asthma may be more susceptible and affected by the niacin flush. However, taking 325 mg of aspirin could help prevent the niacin flush. Many supplements today are incorporating a slow-release capsule in order to prevent this annoying side effect.

Other studies have shown that vitamin B3 may also help prevent heart attacks. It may reduce triglycerides, reduce LDL cholesterol and raise HDL cholesterol. Niacin may also be able to aid in the absorption of trace minerals.

Another study indicated that women who suffer menstrual cramps may be able to find relief by supplementing with niacin. It also seems to play a role in helping to prevent various forms of cancer. Studies have indicated that it has shown to be effective against various carcinogens.

Niacin Sources

Whole and enriched grain products, as well as meats, are excellent sources of niacin. The body has the ability to convert tryptophan into niacin. Chicken breast, tuna, beef liver and Brewer’s yeast are all excellent sources.
