Linus Pauling said of vitamin B3 (either niacin or niacinamide):
“What astonished me was the very low toxicity of a substance that has such very great physiological power. A little pinch, 5 mg, every day, is enough to keep a person from dying of pellagra, but it is so lacking in toxicity that ten thousand times as much can [sometimes] be taken without harm.”
There are various forms of nicotinic acid that have varying functions:
Inositol Hexanicotinate is a specific form of the Nicotinic Acid (Niacin) form of Vitamin B3 that does not cause the flushing (from Histamine release) that is normally associated with Nicotinic Acid ingestion.
Niacytin is a bound and unavailable form of Vitamin B3 present in some foods, especially Cereals and Grains.
Scientists at EPFL (Ecole polytechnique fédérale de Lausanne), Switzerland, have discovered that a molecule called Nicotinamide riboside has impressive effects on fat burning, diabetes avoidance, stamina, cell aging, etc.
Carles Cantó is the first author to report on this new substance, nicotinamide riboside in an article published in Cell Metabolism on June 5th, 2012.

Nicotinic Acid (Niacin) is the acid form of Vitamin B3.
Xanthinol Nicotinate is a synthetic form of the Nicotinic Acid form of Vitamin B3 that can pass easily through Cell Membranes into Cells much more readily than Niacin
Niacinamide (also known as Nicotinamide) is the main form of Vitamin B3 present in dietary sources. Chemically, it is the Amide of Nicotinic Acid.
Niacinamide increases levels of Nicotinamide Adenine Dinucleotide (NAD).
