Participants: Healthy overweight adults between the ages of 45 and 55 
Dosage: 3 grams/day of ginseng for 28 days

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

Aging &amp; Longevity

Model: Young (2- to 4-month-old) and aged (9- to 10-month-old) C57Bl/6JR mice, APP/PS1 mice, and 5xFAD mice 
Dosage: 0.2 mg/mL of doxycycline in drinking water starting at least 7 days before surgery and ceased 2 days before the partial cellular reprogramming window for engram tagging, after which it was immediately reintroduced

Gene Therapy Restores Cognitive Function in Aging and Alzheimer’s Disease

Delivering a gene therapy targeting ensembles of neurons that store memories restores learning and memory capabilities in mouse models of aging and Alzheimer’s disease.

(The study’s principal investigator, Professor Johannes Gräff | 24 Heures)

A partial cellular reprogramming gene therapy targeting memory trace cells restores facets of learning and memory in aged mice and those modeling Alzheimer’s disease.

Brain &amp; Neurons

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

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

Unpublished Results Show NMNH Triples NAD+ in First Human Trial

According to newly released results from a first-of-its-kind clinical trial, reduced nicotinamide mononucleotide (NMNH) triples circulating NAD+ and improves subjective quality of life scores.
