Longevity

Alpha-Ketoglutarate, an Endogenous Metabolite, Extends Lifespan and Compresses Morbidity in Aging Mice

–
Randomised Controlled Trial

Dosage: CaAKG at 2% w/w in diet starting at 18 months of age in mice – human equivalent is 15.1 mg per kilogram per day (For a 70 kg human, this would translate to about 15.1 mg/kg/day or a total daily dose of 1,059 mg)

Outcome: Extension of lifespan and reduction in frailty, with significant improvements in healthspan

Summary: CaAKG supplementation extended lifespan in female mice by up to 19.7% and significantly reduced frailty in both male and female mice.

Rejuvant®, a potential life-extending compound formulation with alpha-ketoglutarate and vitamins, conferred an average 8 year reduction in biological aging, after an average of 7 months of use, in the TruAge DNA methylation test – Retrospective Analysis

Dosage: Two tablets of Rejuvant® containing 1 gram of CaAKG for 4 -10 months

Outcome: Average decrease in biological ageing of 8 years

Summary: This study found that taking a supplement called Rejuvant®, which contains alpha-ketoglutarate for about 7 months, can make your body’s biological clock show you’re about 8 years younger than before you started. It suggests this could be a way to potentially slow down the ageing process.

Dosage: Up to 100 micromole of AKG per litre of solution

Outcome: Increased lifespan in fruit flies

Summary: Adding AKG to the diet of fruit flies extended their lifespan by turning on AMPK signalling and turning off mTOR pathways. It did not improve resistance to oxidative stress or starvation but did increase resistance to heat and activity of genes related to stress response.

Alpha-ketoglutarate as a potent regulator for lifespan and healthspan: Evidences and perspectives – Review

Dosage: 1000 mg Ca-AKG for 7 months (in humans)

Outcome: Increase in lifespan and healthspan across various models (C. elegans, Drosophila, mice, and implications for humans) due to alpha-ketoglutarate (AKG)

Summary: AKG shows potential as an anti-ageing compound by influencing various cellular processes, including energy metabolism and epigenetic regulation. Studies in animal models demonstrate that AKG supplementation can extend lifespan and improve healthspan, suggesting promising applications for delaying ageing and enhancing longevity in humans.

Alpha-ketoglutarate extends Drosophila lifespan by inhibiting mTOR and activating AMPK – Experimental Study

Dosage – Up to 1000 micromoles of AKG per litre of solution

Outcome: Extended lifespan and increased heat stress resistance; decreased reproductive performance

Summary: Adding AKG to the diet of fruit flies increased their lifespan and improved their ability to resist heat stress. AKG worked by turning on a longevity-promoting signal (AMPK) and turning off a growth signal (mTOR) in the flies.

Everything You Need To Know About CaAKG

Alpha-Ketoglutarate (AKG) is a naturally occurring compound in the body and a key component of the Krebs cycle, the body’s main energy-producing pathway that converts food into useable energy within cells. Once nutrients enter the cell the cycle uses AKG to extract energy from them.

The Calcium Alpha-Ketoglutatrate (Ca-AKG) form of AKG is the molecule used in the 2020 landmark longevity study, which showed that AKG has a positive effect on reducing frailty and increasing lifespan.

Although AKG is a key component of the Krebs cycle, the benefits of supplementation are thought to have a dual role. The body typically produces enough AKG, and deficiencies are rare; however, AKG production declines with age. In addition to replenishing levels, externally supplied AKG has been studied for its ability to disrupt cellular energy balance, triggering a stress response that downregulates mTOR, a key regulator of growth and metabolism linked to accelerated ageing when overactivated.

The mTOR (mechanistic target of rapamycin) pathway is a major regulator of cell growth, protein creation, and energy consumption. When nutrient and energy levels are high, mTOR is activated, promoting growth processes. However, chronic mTOR activation accelerates ageing by driving excessive growth and reducing the cell’s ability to repair and resist stress.

Externally supplied AKG appears to have a dual effect on cellular energy. As well as ensuring the body has enough AKG to create cellular energy (ATP), it may inhibit limit enzymes responsible for the final step in ATP production. This inhibition reduces ATP levels, activating energy-conserving pathways such as AMPK, which in turn inhibits mTOR activity.

These pathways—AMPK and mTOR—are believed to be key mechanisms by which CaAKG supports longevity and bone health. It slows excessive growth, switches on cellular repair processes, and allows the body to better respond to stress.

Healthy AKG levels ensure efficient cellular energy production to power all essential cellular processes. General mitochondrial function decline and damage, slower metabolism and decreased muscle mass (a major source of AKG production) all contribute to decreases in AKG production over time. By maintaining healthy AKG levels, the body can efficiently produce energy, support cellular repair, and sustain healthy metabolism. Optimal AKG levels help the body function at its best.

In addition, healthy mTOR activation is a balanced, context-dependent response that promotes growth and repair when nutrients are abundant and deactivate during low-energy states to support cellular maintenance and stress resistance. However, mTOR can become overactive due to chronic overnutrition, such as excessive calorie and carbohydrate intake. Certain conditions like obesity, insulin resistance, and metabolic disorders further drive excessive mTOR activation. This overactivity can impair autophagy (the process of clearing damaged cells), reduce cellular repair, and increase oxidative stress.

Studies show that after age 40, Alpha-Ketoglutarate levels begin to decline, and supplementation can help counteract this drop, promoting optimal cellular function. A landmark longevity study demonstrated improved lifespan and reduced frailty in ageing mice, believed to be due to CaAKG’s ability to inhibit excessive mTOR activation, enhancing autophagy, cellular maintenance, and stress resistance, ultimately supporting healthier ageing and increased longevity.

Consider the following statements. If you find one or more relatable, CaAKG might be the support you’ve been searching for:

  • I want to incorporate CaAKG into my longevity protocol after reading about its benefits in promoting healthspan and potentially extending lifespan.
  • I am intrigued by research suggesting that CaAKG can help reduce frailty and morbidity in later life. 
  • I’ve learned about the potential of CaAKG to support muscle strength, and maintain bone density.
  • I understand that no single supplement is a magic pill, but I’m interested in CaAKG’s broad range of benefits that align with my health and longevity goals..
  • My healthcare provider has discussed the importance of managing cellular health as I age, and CaAKG has come up as a recommendation.

Frequently Asked Questions

CaAKG is alpha-ketoglutarate bound to calcium, whereas other forms of alpha-ketoglutarate often use the amino acid arginine as a base. Studies suggest that binding with calcium may improve the absorption and effectiveness of alpha-ketoglutarate. CaAKG was also the form used in the landmark longevity study related to lifespan and age-related frailty.

CaAKG is not naturally found in foods, though alpha-ketoglutarate (AKG) does occur in small amounts in red meat, fish, and dairy products. Interestingly, ketogenic diets are thought to help conserve AKG levels in the body.

While there is no established upper limit for CaAKG, excessive amounts may cause gastrointestinal discomfort. CaAKG also contains calcium, which may not be suitable for individuals with kidney issues or those on long-term medications. We recommend consulting your healthcare provider before starting CaAKG if you are on any ongoing medications.

In mouse studies, CaAKG reduced fur greying, likely due to its protective effects on melanocytes (pigment-producing cells), its support for mitochondrial function, and its benefits for stem cell health. While further research and human studies are needed, these findings suggest that CaAKG may help reduce hair greying.

The best time to take CaAKG is typically in the morning, as it supports energy metabolism, to align with your body’s natural daytime activity and energy needs.
