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.

Based on current scientific evidence, Dutch researchers have ranked existing anti-aging interventions based on how likely they are to protect against DNA damage and aging.

DNA Repair

Model: Male C57BL/6J mice 
Dosage: 150 mg/kg/day of diallyl sulforated compounds in food

Diallyl sulfonated compounds (DAS), found in garlic, extend the lifespan of mice while counteracting signs of aging, such as grip weakness and memory loss.

How to Boost Mitochondrial Tissue Density and Quality for Longevity

Lifestyle hacks contrived to promote the tissue density and quality of mitochondria (the cell’s powerhouses) can aid in the efficient generation of cellular energy and reduce inflammation, thereby promoting longevity.

Exercise, nutritional support, and lifestyle hacks like cold exposure can all help mitigate mitochondrial dysfunction, a key hallmark of aging.

New Study Shows Cranberry Extract Equivalent to Metformin in Fighting Aging

Fayoum University researchers found that cranberry polyphenols improve metabolic markers, cognition, and oxidative stress to the same degree as the drug metformin.

A new study suggests cranberry extract has effects against aging that rival metformin.
