Rejuvant Outperforms All Other Supplements, Including Standard AKG and NAD+ in Landmark Aging Cell Study

Ponce De Leon Health highlights a landmark independent peer-reviewed study in Aging Cell showing that among 84 supplements tested, only Rejuvant achieved statistical significance — associated with an average 1.8-year lower biological age residual. Standard CaAKG was 8× less effective; NMN/NR were 9× less effective. Both Dr. Brian Kennedy and Dr. Nir Barzilai commented on the findings.

Rejuvant Reduces Biological Age by 8 Years in Humans

A retrospective study of 42 healthy individuals using Rejuvant (CaAKG + gender-specific vitamin) over 7 months showed an average reduction of 8 years in biological age, measured by DNA methylation clocks. The benefit was robust across age and sex and especially pronounced in older participants. This is the first published human evidence showing such a marked age reversal using Rejuvant’s specific form of CaAKG.

AKG Supports Muscle Health, Recovery, and Endurance

This review explores AKG’s role in preventing muscle atrophy and enhancing regeneration. In preclinical and human studies, AKG improves satellite cell proliferation and muscle repair, reduces inflammation through macrophage polarization, and enhances endurance and recovery in active individuals. It also activates mTOR and boosts energy production under stress, highlighting its relevance for aging muscle, injury recovery, and performance support.

The Antioxidative Function of AKG and Its Applications

AKG directly scavenges reactive oxygen species (ROS) like hydrogen peroxide, converting them into harmless byproducts through oxidative decarboxylation. It also fuels ATP production via the TCA cycle and promotes synthesis of glutamine and glutamate, critical to redox balance. Studies show AKG reduces oxidative stress across organs including brain, liver, and gut—highlighting its therapeutic potential in aging and inflammation-related disorders.
