  • Alpha-ketoglutarate (AKG) is a compound that is created naturally in the body but tends to diminish with age. In supplement form, AKG can be attached to a calcium salt (Ca-AKG), which has been studied for its role in supporting metabolic function and longevity. 6
  • Ca-AKG is involved in stimulating protein synthesis and energy production in the body, as it is a vital component of the Krebs cycle - the process that creates ATP (energy) from food. Ca-AKG is also a source of the essential amino acids needed to make collagen, which is a protein that helps to support bone and muscle health.
  • Ca-AKG facilitates our internal recycling process known as autophagy, which removes dysfunctional cells, cell parts and proteins from the body. Autophagy tends to decrease with age, so Ca-AKG may be able to help support this process.
  • Adding calcium to AKG helps to slow the absorption of AKG allowing it to work longer in the body.
  • Better Absorption. Compared to other products that commonly use unbound AKG or AKG bound to arginine, our AKG is bound to calcium. This combination has been shown to promote extended lifespan and health span in mice, even when administered late in life. It also helps to slow the absorption allowing it to work longer in the body.
  • Research-Supported. Calcium AKG Longevity is formulated using 1,000 mg of calcium alpha ketoglutarate, which has been shown in clinical research to promote longevity by reversing biological age (measured by biological age tests), improve markers of heart health and decrease risk of age-related decline in bone health.
  • Quality Manufacturing Practices. All of our products are manufactured in an FDA-registered, GMP-certified facility.
  • Third-Party Tested in the USA. Every batch is third-party tested in US laboratories to ensure the highest quality, purity and potency. Certificates of Analysis are available.

"This is an awesome product. It has slowed and reversed my graying hair. I am 52 and would usually color my edges every 3 weeks but since using this product (1x every other day) for the last month, I've noticed way less gray coming in and have decided to stop dying my edges. Good quality product!"

Biological Age Improved

Took this for a year in between Tally biological age tests. 5 year drop in biological age. I will certainly continue with taking 1000 mg of CaAKG.

One of the best longevity supplements, at one of the best prices!

This is one of the best longevity supplements that I have been able to tell the difference it makes. With Prohealth I know that what’s on the front of the bottle and the label is what’s on the inside of the bottle!

I have had great energy since taking Calcium AKG. It has been helping me with all of the yard work this spring.

Calcium AKG

Not feeling great when taking the Calcium AKG. Feeling sleepy and somewhat drowsy. Also my stomach seems bothered by the supplement. Will continue to take till the bottle is empty but not sure I will continue to take after that.
