This No-Flush Niacin product from Source Naturals is formulated to deliver the benefits of Vitamin B3 without the uncomfortable flushing sensation associated with nicotinic acid, likely using inositol hexanicotinate. This makes it an attractive option for individuals sensitive to the flush but still wanting Niacin's general benefits for energy and metabolism. However, nutritionists and research suggest that No-Flush Niacin forms are generally less effective for significant lipid management (lowering LDL, raising HDL) compared to equivalent doses of nicotinic acid. Online reviews reflect varied experiences, with some appreciating the lack of flush and others questioning its potency for specific therapeutic effects. The higher price per serving also impacts its overall value.
