Model: Young acquired niacin dependency (ANDY) mice. 
Dosage: 30 mg/kg/day of niacin

Mice engineered to have low body-wide NAD+ levels exhibit a shortened lifespan and widespread physical decline, which is largely reversed with the NAD+ booster niacin. 

Life Biosciences reports preliminary visual-field improvements in two of three glaucoma patients treated with the experimental therapy developed by Dr. David Sinclair’s Harvard team, ER-100.

Model: 6- to 8-week-old male C57BL/6J mice
Dosage: 0.5 mg/kg of isolated mitochondria injected every two days for six injections in the tail vein

Mitochondrial Transplantation Rejuvenates Aging Hearts, Study Finds

Transplantation of the cell’s powerhouses (mitochondria) improves heart function by restoring mitophagy (the cellular process that clears damaged mitochondria) in a mouse model of cardiac aging.
