Model: Middle-aged cynomolgus monkeys
Dosage: 30 mg/kg/day of vitamin C, orally administered for 40 months

Vitamin C improves brain volume and connectivity, reduces biological age, enhances metabolic health, and alleviates underlying aging drivers, such as cellular senescence, in older monkeys.

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.

Model: Naturally aged 24-month-old C57BL/6 mice 
Dose: 0.1 mg/kg/day of folic acid administered orally for 12 months

Supplementation with vitamin B9, also known as folic acid or folate, prevents cellular senescence and slows vascular aging in naturally aged mice.
