Niacin (Vitamin B3) is one of
the most valuable vitamins because is has an effect
on 50 different body functions. For example, Niacin
is needed for proper circulation and healthy skin.
It is also involved in the production of sex hormones,
including testosterone, and is an excellent vasodilator.
One thing to note is that the FDA is currently
investigating the use of Niacin. The following is taken
directly from the FDA website:
"Niacin taken in high doses is known to cause a wide range of adverse effects.
The RDA for niacin is 20 milligrams. Niacin is marketed in dietary supplements
at potencies of 250 mg, 400 mg, and 500 mg, in both immediate and slow-release
formulations. Daily doses of 500 mg from slow-release formulations, and 750 mg
of immediate-release niacin, have been associated with severe adverse reactions,
including gastrointestinal distress (burning pain, nausea, vomiting, bloating,
cramping, and diarrhea) and mild to severe liver damage. Less common, but more
serious (in some cases life-threatening), reactions include liver injury, myopathy
(muscle disease), maculopathy of the eyes (injury to the eyes resulting in decreased
vision), coagulopathy (increased bleeding problems), cytopenia (decreases in
cell types in the blood), hypotensive myocardial ischemia (heart injury caused
by too low blood pressure), and metabolic acidosis (increases in the acidity
of the blood and urine)."
