Niacin for Allergies
Gean (Salina, Kansas) on 09/17/2012: My husband has had ragweed allergies for many years, and we've tried everything. Many times he had to sleep sitting up in a chair during the ragweed season because he couldn't breathe lying down, because of nasal congestion. This year he tried niacin, and within 20 minutes of taking it he has no more symptoms whatsoever. It has to be nicotinic acid, the kind that makes you flush. He takes 750 to 1000 mg twice a day. If the pollen count is very high he has to take the higher dose, otherwise 750 will do it. Do not take the no-flush kind, or the slow release kind. Has to be nicotinic acid - you can get it at health food stores. Do not take it more than twice a day, otherwise it can be harmful to the liver. Take at least as much mg vitamin C as niacin per day.
