Participants: Adults over the age of 60
Dosage: 3,750 mg of niacin twice daily (after gradual dose increase), 150 mg of dihydroberberine twice daily, 50 mg of taxifolin (with 500 mg of vitamin C and 15 mg of zinc) twice daily, 50 mg of tocotrienols twice daily

A combination of supplements, including the NAD+ precursor nicotinic acid, improves cholesterol, allowing some participants to cease taking statins.  

Study conducted by Professor Emeritus Joseph Keenan, MD, at the University of Minnesota. 

Nicotinic Acid

Participants: Healthy male adults between the ages of 18 and 50 
Dosage: 714 mg/day of nicotinamide and 19 mg/day of pyridoxine for nine days

In a randomized human trial, combining nicotinamide with vitamin B6 increases stem cell activation and muscle-growth capacity in response to exercise. 

Skin &amp; Muscle

Model: Male Sprague-Dawley rats 
Dosage: 400 mg/kg of magnesium L-theanine and 600 mg/kg of nicotinamide riboside administered orally for 40 days

Scientists find that treating rats with magnesium L-theanine and nicotinamide riboside (NR) counteracts stress-induced metabolic, gut, and liver aging. 

Study conducted by researchers from Firat University in Turkey (image: turkeyuniversity.org)

Model: Primary hippocampal neurons from non-transgenic C57BL/6 (nTg) and triple-transgenic 3xTg-AD mice; age groups: young (2–6 mo), middle (8–11 mo), and old (17–28 mo).
Dosage: Nicotinamide 2 mM + EGCG 2 µM applied to cultured neurons for 16 h (in vitro).

Study shows that brief nicotinamide + EGCG treatment restores neuronal energy in 16–24 hours, restores autophagy, reduces amyloid-beta buildup, and boosts neuron survival by ~22% in aging/Alzheimer’s lab models.
