As a core component of the tricarboxylic acid (TCA) cycle, α-ketoglutarate serves as a critical hub in the body's metabolism. It exerts physiological functions by regulating multiple dimensions, ranging from cellular energy metabolism and gene expression to substance synthesis. Its core mechanisms of action center on energy metabolism, protein synthesis, and redox balance. The specific functions are as follows:
Support Cellular Energy Metabolism, Boost Body Vitality
AKG can freely diffuse across the outer mitochondrial membrane and traverse the inner mitochondrial membrane via the malate-aspartate shuttle system. It directly participates in the tricarboxylic acid (TCA) cycle to supply energy to cells, bypassing the preparatory stages of glycolysis and the TCA cycle, thereby greatly enhancing the body's metabolic efficiency. Meanwhile, as a precursor to glutamine and glutamate, it ensures the normal operation of cells in the liver, kidneys, intestines, as well as the immune system and neurons.
Additionally, AKG can activate the AMPK signaling pathway, reduce muscle energy expenditure, promote fat metabolism, increase the body's energy reserves, and thus improve the overall energy state.
AKG can significantly suppress the expression of mTOR and the activity of ATP synthase, downregulate aging-related signaling pathways, and reduce the release of chronic inflammatory factors, thereby delaying cellular senescence. Human clinical trials have demonstrated that daily supplementation with an appropriate amount of AKG can reduce the biological aging age by an average of nearly 7.8 years, effectively mitigating age-related physiological decline. Moreover, AKG can enhance the telomere maintenance system, inhibit reproductive aging, restore ovarian reserve and fertility, and delay the age-related decline in the quality and quantity of oocytes.

Promote Protein Synthesis, Enhance Muscle Growth and Fat Loss, and Improve Athletic Performance
As a precursor to glutamine, AKG supplies raw materials for the synthesis of non-essential amino acids, driving the process of protein synthesis in the body. Meanwhile, through the PHD3/ADRB2 pathway, it prevents skeletal muscle protein degradation, reduces the risk of muscle atrophy, and thus increases muscle mass and strength;
AKG activates adrenal signaling pathways to enhance thermogenesis
and lipolysis, thereby supporting weight loss and metabolic regulation.
It can specifically promote brown fat formation, activate the OXGR1-dependent adrenal pathway, reduce white fat accumulation, shrink adipocyte volume, and effectively prevent diet-induced obesity. In the field of sports, AKG can enhance maximal aerobic power, reduce post-exercise lactic acid buildup, extend endurance exercise duration, improve anaerobic strength and jumping ability, while preventing the risk of post-exercise ammonia poisoning and accelerating post-exercise recovery.
AKG can regulate histone methylation, promote the proliferation, migration, and osteogenic differentiation of bone marrow mesenchymal stem cells, increase bone mass in the elderly, and accelerate bone tissue regeneration. It can lower the level of C-terminal telopeptide of type I collagen (CTX) in the serum of postmenopausal women, enhance lumbar spine bone mineral density, and inhibit bone resorption and mineral loss. Meanwhile, AKG promotes chondrocyte metabolism, facilitates the accumulation of extracellular matrix, and reduces the toxicity caused by ammonia accumulation in the culture medium, comprehensively protecting bone and joint health.
