Ginseng Boosts NAD+ and Telomeres: New Study in Middle-Aged Adults

Ginseng supplementation boosts NAD+ (nicotinamide adenine dinucleotide) and lengthens telomeres in middle-aged adults, suggesting an amelioration of aging.

Aging &amp; Longevity

Model: 11-month-old male C57BL/6J mice 
Dosage: 30 mg/kg/day of NTX-748 (based on a small molecule called 78c) for 4 months, administered orally

Blocking NAD+ Breakdown Improves Cognitive and Physical Performance

Buck Institute scientists find that blocking the CD38 enzyme, which elevates NAD+ (nicotinamide adenine dinucleotide), counteracts age-related cognitive and physical decline in mice.

Brain &amp; Neurons

Participants: Healthy middle-aged adults 
Dosage: 1200 mg/day of NR for 4 weeks

NR Raises NAD+ 2-Fold More than NMN

NR (nicotinamide riboside) raises blood NAD+ (nicotinamide adenine dinucleotide) levels more than NMN (nicotinamide mononucleotide) in healthy adults.

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 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.
