<p>Model: 24-month-old male C57BL/6J mice </p>
<p>Dosage: 1% w/v of betaine for three weeks </p>


The naturally occurring compound betaine is elevated in healthy adults after long-term exercise and mitigates signs of aging in mice.

Scientists Discover Deer Antler Stem Cells That Reverse Aging in Mice and Monkeys

Researchers discover that deer antler stem cells can restore bone density, slow aging, and reverse biological age in mice and primates.

Aging &amp; Longevity

<p>Model: Male C57BL/6 mice given continuous alcohol for 4 weeks </p>
<p>Dosage: 350 mg/kg/day of nicotinamide riboside chloride for 2 weeks </p>


The NAD+ (nicotinamide adenine dinucleotide) precursor nicotinamide riboside chloride (NRC) counteracts neuronal damage caused by alcohol consumption in mice. 

Brain &amp; Neurons

NAD+ (nicotinamide adenine dinucleotide) may contribute to healthy cellular aging by enhancing biological energy flow, according to the newly formulated energy resistance principle.


<p>Model: Male Sprague-Dawley rats </p>
<p>Dosage: 400 mg/kg of magnesium L-theanine and 600 mg/kg of nicotinamide riboside administered orally for 40 days</p>


Scientists find that treating rats with magnesium L-theanine and nicotinamide riboside (NR) counteracts stress-induced metabolic, gut, and liver aging.
