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.
