Researchers have been studying this derivative of the enzyme relative to niacin for decades. In scientific journals, it has shown excellent anti-aging results in studies, reversal of symptoms in up to 50% of Parkinson’s disease patients, reduced alcohol craving during recovery treatment, and even halting progression of Alzheimer’s symptoms in one study. That’s in addition to many more casual studies reporting general increases in energy, stamina, mood, and mental sharpness. No wonder it’s the go-to regenerative therapy for the “feelin’ stronger every day” crowd!
