Do not take niacin supplements if
you are not under the supervision
of a health care professional.
Doses of 75 mg or more cause blood-vessel dilation, which can result in tingling, itching, and flushing of the face, neck, and chest -- a condition called niacin flush. It is uncomfortable but not dangerous. Starting with 50 to 75 mg three times per day and slowly increasing the amount can help minimize this problem. Also, many people find that by taking an 83 mg aspirin with the niacin, the flushing is greatly reduced. Aim to reach the full dose desired by six weeks; always take it with meals to avoid gastric irritation and nausea. If you want to find the best prices on B vitamin supplements, click here.
Inositol hexaniacinate has very few side effects. People's blood cholesterol levels go down, HDL cholesterol levels go up, and there are no flushing symptoms or liver problems. Again, seek professional supervision and remember to start slowly. Take about 500 mg three times per day for two to three weeks, then increase to 1,000 mg three times per day. Take it with meals for best results.
Doses used for children who were starting to develop insulin-dependent diabetes ranged from 100 to 200 mg per day. Adult doses are based on weight: approximately 11.5 mg per pound of body weight.
Warning: People who have any type of liver disease, high levels of liver enzymes in their lab reports, gout, or peptic ulcers should not take niacin. When taking any type of vitamin B3 supplement discussed here, it is important to check liver function periodically. If you take more than 500 mg of niacin, or 3,000 mg or inositol hexaniacinate or niacinamide per day, your doctor should check your liver enzymes levels at least every three months.
As we've just learned, niacin is necessary to provide energy for the body and to ward off pellagra, and it's being used to treat ailments from diabetes to arthritis to migraines. However, too much vitamin B3 is not a good thing. Don't overdo it with your vitamin B3 intake, and this essential b-complex vitamin will help keep your body working properly.
