The flush free serve no purpose in lipid support.
Niacin exists in three forms that are available either as supplements or drugs.
They are nicotinic acid (or just niacin), nicotinamide and inositol hexaniacinate (which is the chemist’s way of describing a chemical composed of one molecule with six niacin molecules stuck to it). This last one is also referred to as ‘flush-free’ niacin.
Of these three forms, niacinamide is the form in which the drug is active as a co-enzyme; the other two have to be broken down into niacinamide before they can be used by the body.
Nicotinic acid is the only form that helps reduces cholesterol.
