University of California (UC) Berkeley scientists moderately extend the lifespan of old mice by giving them oxytocin (sometimes called the "love hormone") and a compound that inhibits inflammation.

Model: UM-HET3 Mice 
Dosage: 0, 75, 150, 300, 600, and 1200 ng epicatechin/mg food; 0, 0.075, 0.15, 0.3, 0.6, and 1.2 ng halofuginone/mg food; and 0, 37.5, 75, 150, 300, and 600 ng mitoglitazone/mg food, all given ad libitum in food starting at seven months old

Three Compounds Show Promise for Male Longevity

Data from a rigorous longevity study show promise for three new compounds, adding to the repertoire of mouse lifespan-extending substances.

The world’s most rigorous longevity study presents data showing promise for three new lifespan-extending compounds in male mice.

Does NAD+ (nicotinamide adenine dinucleotide) really help with aging? A team of international scientists reviews the latest and ongoing clinical trials.

Part of the research team, including Dr. Evandro Fei Fang (middle), from the University of Oslo and Akershus University Hospital in Norway (image: med.uio.no). 

Model: Primary hippocampal neurons from non-transgenic C57BL/6 (nTg) and triple-transgenic 3xTg-AD mice; age groups: young (2–6 mo), middle (8–11 mo), and old (17–28 mo).
Dosage: Nicotinamide 2 mM + EGCG 2 µM applied to cultured neurons for 16 h (in vitro).

Study shows that brief nicotinamide + EGCG treatment restores neuronal energy in 16–24 hours, restores autophagy, reduces amyloid-beta buildup, and boosts neuron survival by ~22% in aging/Alzheimer’s lab models.
