Inositol hexanicotinate form of B3 without the flushing side effect
We rank Niacin Flush Free by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Niacin Flush Free is a specific version of vitamin B3 known as inositol hexanicotinate. Unlike standard niacin, this form is designed to avoid the "flush," which is a temporary reddening and tingling of the skin caused by the widening of small blood vessels.
It is used by people who want the benefits of vitamin B3 without the uncomfortable skin reactions associated with other forms. It provides the essential nutrient needed for energy production and cellular health without causing the skin to feel hot or itchy.
To create this supplement, manufacturers produce inositol hexanicotinate in a powder form. This powder is then measured and packed into capsules or compressed into tablets for sale to consumers.
This ingredient is generally affordable. This is because the raw materials are easy to source and the manufacturing process is straightforward, leading to high supply and significant competition between brands.
