I prefer the form of no-flush niacin called inositol hexanicotinate (IHN). This is a slow release form niacin comprised of six molecules of niacin bound to one molecule of inositol. As it is metabolized niacin levels gradually rise, peaking about 10 hours after ingestion. In Europe this form of niacin is sold as a prescription (Hexopal) and has been extensively tested for safety up to doses of 4,000 mgs per day. There are no reports of liver problems from this form of niacin (flush has reports of some liver problems due to increased detox during the flush) and it does not cause a flush.

The niacin flush and upset stomach that are so common in other forms of niacin cause many people not to take niacin who may benefit. The niacin flush triggers mast cells to release chemicals, and constantly doing this is not likely to be beneficial.

Looks as if you new regimen is a winner, just don't go over recommended dosage to avoid any side effects. Good luck.

Flushing is likely to increase anxiety, so a no-flush variety would be better in that respect. You should be aware that there is little or no evidence that niacin is an effective treatment for anxiety and that niacin is not considered a valid treatment for anxiety or by the U.S. Food and Drug Administration or the American Medical Association.

Also:

"When doses of over 3 grams per day of niacin are taken, more serious side effects can happen. These include liver problems, gout, ulcers of the digestive tract, loss of vision, high blood sugar, irregular heartbeat, and other serious problems. Similar side effects can happen with large doses of niacinamide.

Some concern has been raised about stroke risk in people taking niacin. In one large study, people who took high doses of niacin had a two-fold greater risk of stroke compared to those not taking niacin. But it is unclear if this outcome was due to niacin or some other unknown factor. Previous research has not identified any stroke risk related to taking niacin. Most experts believe that it is too soon to jump to any conclusions about niacin and strokes."

You need to be careful taking niacin if you have a heart condition, liver or kidney problems, diabetes, low blood pressure or ulcers.

A pharmacist told me that no flush niacin was hard on the liver. I bought 500mg. niacin and i bite them into 3rds, it's easy enough. there is still a 'flush' but it is not that severe. you can eat something and that helps, also take asprin with it.
