Model: 6-week-old ICR mice
Dosage: 250 mg/kg per day or 500 mg/kg per day of glucosamine and 100 mg/kg per day or 200 mg/kg per day of aspirin for either eight (acute alcohol exposure model) or 40 days (chronic alcohol exposure model)

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.
