Flush-Free Niacin (Vitamin B3) 500mg is one of HSN's star products.
Want to know more? Read on!
Flushing is the classic effect of nicotinic acid as a form of niacin (vitamin B3) through activation of HM74A and HM74 receptors on certain human dermal cells (Pike, 2005).
This results in a reddening of the face and body, accompanied by burning and/or itching.
Other forms of niacin, however, do not have this undesirable effect associated with them, most notably Inositol Hexanicotinate, known as the reference form for the development of flush-free formulas of the vitamin.
Flush-Free Niacin (Vitamin B3) 500mg has been developed in the form of Inositol Hexanicotinate, 100% flush-free, without redness.
The Hexanicotinate form of Inositol consists of:
- Niacin.
- Inositol.
The composition of each vegetable capsule of the product is as follows:
- 500mg of Niacin (Vitamin B3).
- 133mg of Inositol.
Sourced from 633mg of pure Inositol Hexanicotinate.
Each vegetable capsule of the product contains 500mg of Niacin, a completely safe and easy-to-acquire amount.
You only need one veg capsule a day to reach the recommended daily dose.
Flush-Free Niacin from HSN is 100% suitable for vegans.
We achieve this by developing capsules with hypromellose as a coating agent, a compound derived from vegetable cellulose, eliminating the gelatines that are normally used in the industry and that make the products unsuitable for vegans.
