Buck Institute on Aging studies reveal Rejuvant’s® ingredients hold the promise to reverse epigenetic aging.

Preliminary research at the Buck Institute on Aging, the preeminent independent research facility dedicated solely to aging research, showed sustained-release Calcium Alpha-Ketoglutarate may be an effective strategy in slowing down the aging process. In their landmark mammal study, Rejuvant’s LifeAKG™ increased the healthiest years of life by 41% and reduced the manifestations of age-related frailty by 46%.

Rigorous research leads to precise formulation.

In humans, long-term use of Rejuvant® reduced biological age significantly.

Unlike many others in the supplement industry, Rejuvant was developed with meticulous scientific research. Millions of dollars and years of research confirmed our hypothesis that Calcium Alpha-Ketoglutarate in specific combinations can delay the aging process. More than a dozen separate laboratory trials evaluated multiple compounds on mammals to assess effectiveness. Hundreds of combinations of these compounds led to the development of Rejuvant. 


A randomized retrospective study of 42 individuals taking Rejuvant (seen on the left) resulted in an average decrease of eight years in biological age after approximately seven months of usage. This study validates the effectiveness of Rejuvant in reducing biological age in a short amount of time and expanding the years a person can stay in good health.

Patent-pending sustained release mechanism.

We tested hundreds of formulations before developing our proprietary tablets. LifeAKG™, our propietary Calcium Alpha-Ketoglutarate, was formulated in a sustained release matrix to allow it to pass through the stomach and reach the upper small intestine, where it is best absorbed. We then combined the LifeAKG™ with vitamin A and D to make our proprietary formulas for men and women which allow for increased absorption. You need only two tablets, once a day, to live a healthier life.

The Rejuvant® Difference

Unlike generic AKG, only LifeAKG™ is precisely formulated for a proprietary sustained release profile to effectively deliver the benefits of AKG to the body.

Safe and effective as documented in peer-reviewed publications.

Rejuvant is composed of naturally occurring ingredients in your own body: Alpha-Ketoglutarate and Calcium. Research studies in the most respected scientific journals in the world—including Cell Magazine, Science, Lancet, Clinical Toxicology, and the National Center for Biotechnology Information at NIH—confirm the safety for humans of Calcium Alpha-Ketoglutarate when taken as directed.

Manufactured to the highest standards of purity.

We manufacture Rejuvant in the US, on a standard production line. Unlike most other supplements, our patented manufacturing process uses a purpose built production line dedicated solely to Rejuvant, including a biologically-pure USP water filtration system, so we can guarantee Rejuvant’s purity. Rejuvant produces AKG that is proprietary to Ponce De Leon Health, sustained release to maximize delivery, and over 98% pure.

Gauge your age: true biological age testing.

While your chronological age is the number of years that you’ve been alive, your biological age is the true reflection of how your cells are aging. Your biological age is best revealed through DNA analysis. Rejuvant has partnered with TrueMe Labs, makers of the TrueAge Explorer Test, the first-ever direct to consumer epigenetic test, to allow you to see how your biological age compares to your chronological age and how it can change over time with additional testing.


Taking the test is easy. Send a small amount of your saliva to TruMe Labs—an independent laboratory run by Stanford and Harvard-trained scientists—with the collection materials provided. TruMe will process your genomic DNA and compare it to profiles of the human genome to create biomarkers for your unique aging pattern. These results are correlated into a TrueAge Index™, reflecting age-related changes in your metabolism, physiology, and lifestyle which together make up your true biological age.


To most effectively monitor your aging process, we recommend tracking your TruAge Index when you begin taking Rejuvant, and again after seven months. Using the results in the TrueAge report will provide insight into your changing DNA methylation patterns and enable you to track your true biological age.
