Calcium AKG is a highly dosed calcium alpha-ketoglutarate (Ca-AKG) food supplement.
Alpha-ketoglutarate (AKG) is a molecule involved in the production of cellular energy and is being studied for its potential ability to slow down the ageing process. When combined with calcium, AKG is much more stable and bioavailable.
Calcium AKG is classified in our Longevity category.
Alpha-ketoglutarate (AKG) is an organic acid, naturally present in the body, that plays a decisive role in the Krebs cycle, a central metabolic process taking place in the mitochondria.
This cycle is essential for the production of cellular energy (ATP) and the proper functioning of the mitochondria, which are involved in the vitality and longevity of cells.
More specifically, AKG is thought to:
AKG levels fall sharply with age, being up to 10 times lower at 80 than at 40, leading to a reduction in mitochondrial efficiency and oxidative stress.
Numerous animal and human studies suggest that taking AKG orally could extend lifespan and improve overall health as we age (1-4).
The bioavailability and efficacy of AKG taken orally are also considerably increased when it is combined with calcium to form calcium alpha-ketoglutarate.
Calcium AKG differs from other AKG food supplements in 3 ways:
Alpha-ketoglutarate (AKG) is a molecule naturally involved in energy production within the mitochondria.
Various studies suggest that administration of AKG may promote longevity by improving metabolic health and reducing age-related inflammation.
While most calcium supplements are best taken with a meal, it is recommended that AKG calcium be taken on an empty stomach for optimum assimilation.
Organic calcium refers to a form of mineral calcium (Ca²⁺) bound to an organic molecule: citric acid, malic acid or alpha-ketoglutaric acid, as used in this supplement.
This combination generally improves the bioavailability of calcium to the body and can also enhance the absorption of the organic molecule itself, which is particularly illustrated with AKG.
Calcium AKG (Ca-AKG) is mainly studied for its effects on cellular longevity: alpha-ketoglutarate, involved in the Krebs cycle, regulates key pathways of ageing such as mTOR and inflammation, while supporting mitochondrial health.
Ornithine AKG (OKG) combines AKG with ornithine, an amino acid that promotes the elimination of ammonia as well as the natural secretion of growth hormone, making it a support for muscle recovery, regeneration and anabolism, particularly in athletes.
Arginine AKG (AAKG) acts above all on circulation: arginine stimulates the production of nitric oxide (NO), a vasodilator gas that improves blood flow, muscle oxygenation and physical and sexual performance.
Alongside this supplement, you can opt for another innovative ingredient studied for its potential capacity to increase cellular longevity: urolithin A. This metabolite is thought to promote mitophagy, the process of recycling mitochondria:
For additional support, you can also rely on a complete formula combining some of the best ingredients studied for their potential role in mitochondrial health, such as PQQ, alpha-lipoic acid and acetyl-L-carnitine:
