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.

Aging &amp; Longevity

Model: Male ApoE−/− mice fed a high-fat diet for 12 weeks to induce atherosclerosis.
Dosage: Methyl-β-cyclodextrin (Mß-CD) at 2.0 g/kg, subcutaneous injection, twice a week

 A new study shows cyclodextrin reduces artery plaques in mice by lowering cholesterol and blocking inflammatory cell death. 

Cardiovascular

Participants: Healthy middle-aged to older adults (average age: ~53 years) 
Dosage: 1,000 mg/day of urolithin A for 28 days

Supplementing healthy adults with urolithin A —a compound produced by our gut bacteria— counters signs of age-related immune system decline.

Immunity

Model: 24-month-old male C57BL/6J mice 
Dosage: 1% w/v of betaine for three weeks

The naturally occurring compound betaine is elevated in healthy adults after long-term exercise and mitigates signs of aging in mice.
