Model: Healthy adults between 21 and 79 years of age 
Dosage: 395 mg/kg of bodyweight of (R)-3-hydroxybutyl-(R)-3-hydroxybutyrate monoester (𝛽-hydroxybutyrate ketones) diluted in water and administered once

New Study Finds Midlife May Be a Critical Window to Prevent Brain Aging

A new study suggests that supplementing with ketones—molecules the body can use for energy when lacking sugars—prevents cognitive aging when administered in people’s 40s and 50s.

Based on age-related destabilized brain signaling, a new study suggests a critical midlife window where metabolic interventions may stabilize brain signaling.

Model: Two-month-old male C57BL/6J mice fed a high-fat diet to induce obesity 
Dosage: 400 mg/kg/day of NR for eight weeks

Scientists find that NR (nicotinamide riboside) supplementation preserves brown fat tissue in mice, reducing their body weight and maintaining the health of their mitochondria.

NAD+ Supercharges Immune System Recovery in Older Mice

Researchers from the University of California, Berkeley, found that young mice need NAD+ breakdown, while old mice need NAD+ boosting.

Immunity

Model: C57BL/6N male mice 
Dosage: AIN-93 M diet with 0.025% (15 mg/kg per day) niclosamide for the Old + NL group or 0.050% (30 mg/kg per day) niclosamide for the Old + NH group, starting at 12 months of age to 21 months of age

Drug Approved Against Tapeworms May Counteract Aging, Suggests New Study

New research suggests niclosamide, approved for human use against tapeworms, alleviates frailty and suppresses the protein complex mTOR, which regulates cell growth, in aged mice.

Niclosamide, an agent approved for human use against tapeworms, alleviates age-related frailty, suppresses mTOR, and activates autophagy in old mice.

Aging &amp; Longevity

The NAD+-consuming enzyme CD38 is elevated in individuals predisposed to Alzheimer’s, and blocking it improves the metabolic health and cognition of mice that model Alzheimer’s.
