What is NAD?

Finnish scientists used a new measurement system to detect low NAD+ levels in blood samples from people with a range of age-related conditions, but not in healthy older individuals.

The plant-based antioxidant, pterostilbene, improves egg quality in aged mice, as measured by an increase in live offspring.

Scientists discover that inosine—a type of molecule called a purine nucleoside—alleviates multiple-organ aging in mice, and restores the oxygen delivery capacity of red blood cells.

Changes to Bryan Johnson’s latest supplement stack include taking NMN or NR six days a week, rather than seven, and eliminating the use of rapamycin.

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.

Researchers at Case Western Reserve University have shown that late-stage neurodegeneration may be biologically reversible, at least in the right conditions, in mice.

A naturally occurring compound, α-lipoic acid, helped elderly mice think like younger mice by restoring energy balance and calming brain inflammation, according to Second Hospital of Hebei Medical University researchers.

In older adults, the combination of nicotinamide, palmitoylethanolamide (PEA), oleoylethanolamide (OEA), and spermidine counters cardiovascular and metabolic aging.

Stanford neuroscientist Andrew Huberman’s updated supplement list includes the NAD+ precursor NMN, along with other compounds for sleep and cognitive performance.

Harvard researchers find that aged mice lacking gut bacteria exhibit a brain more like that of young mice.
