There are a lot of questions as of recent regarding the inclusion of Niacin in PRE-KAGED. There are two primary forms of vitamin B3 and they are called Niacin and Niacinamide (Nicotinamide). Niacinamide is NOT the flushing form of vitamin B3, rather niacin (nicotinic acid) is the FLUSHer. Bottomline: NOT ALL B3 vitamins flush! Nicotinamide adenine dinucleotide (NAD), is a coenzyme found in all living cells. And you are only as healthy or energized as your collective cellular essence.
