The average adult needs about 14 milligrams per day, so megadoses of individual niacin supplements are far more than anyone needs. To avoid or lessen the niacin flush, you could use time-release forms of niacin, which are absorbed and metabolized slower than regular niacin. Taking a regular aspirin about 30 minutes before taking niacin supplements may also help reduce the discomfort, but probably won't eliminate it altogether. Another alternative is inositol hexanicotinate, which your body converts to niacin.
The conversion is slow enough that it doesn't cause a flush in most people. The problem is that you may not get the same lipid-lowering benefit as regular niacin. A review study reported that inositol hexanicotinate was no better than a placebo for lowering cholesterol levels. Along with thiamin, riboflavin , and others, niacin is an essential B-complex vitamin your body needs to convert macronutrients from the food you eat into energy for daily activities.

As mentioned above, to avoid unwanted symptoms, including flushing, some people opt for extended-release or long-acting niacin. However, extended-release and long-acting niacin differ from immediate-release niacin and may cause different health effects. Because of this, taking long-acting niacin significantly reduced the chances of flushing However, because of the way the body breaks it down, taking long-acting niacin may have toxic effects on the liver, dependent on the dose taken Although uncommon, switching from an immediate-release niacin to a long-acting niacin or significantly increasing your dose can result in serious liver damage Plus, IHN is significantly less effective than nicotinic acid at increasing serum niacin.
IHN usually takes between hours to raise blood levels of niacin to near the optimal range Some studies suggest that peak niacin blood levels can be over times greater when supplementing with nicotinic acid compared to supplementing with IHN.
Research also shows that IHN has minimal effect on blood lipid levels Absorbability differs between forms of niacin. Some types of niacin are more effective at raising blood levels than others.
