Isocitrate Dehydrogenase
Isocitrate Dehydrogenase is a crucial enzyme for energy and antioxidant support. People choose it to power their metabolism and protect their cells.

Origin & History
Isocitrate Dehydrogenase is a mitochondrial enzyme that catalyzes the oxidative decarboxylation of isocitrate to alpha-ketoglutarate in the Krebs cycle. It is naturally produced in the mitochondria of cells.
Historical & Cultural Context
Isocitrate Dehydrogenase has been a focus of biochemical research since the Krebs cycle was discovered, providing insights into cellular energy production and metabolism.
Health Benefits
- Supports efficient cellular energy production by catalyzing the conversion of isocitrate to alpha-ketoglutarate in the Krebs cycle. - Enhances metabolic pathways, ensuring optimal nutrient breakdown and energy extraction. - Promotes antioxidant defense by generating NADPH, a key molecule for cellular protection. - Supports cognitive performance by fueling neurons with critical energy substrates. - Improves muscle function and endurance through sustained ATP supply. - Contributes to cardiovascular health by optimizing heart cell metabolism. - May help slow cellular aging by maintaining mitochondrial health. - Aids in detoxification by facilitating metabolic waste removal.
How It Works
Isocitrate dehydrogenase (IDH) catalyzes the oxidative decarboxylation of isocitrate to α-ketoglutarate in the citric acid cycle, coupled with NAD+ or NADP+ reduction to generate NADH or NADPH. This reaction is critical for ATP generation via oxidative phosphorylation and provides reducing equivalents for anabolic biosynthesis and antioxidant defense through glutathione regeneration.
Scientific Research
Research on Isocitrate Dehydrogenase highlights its role in cellular metabolism and its potential implications in cancer research. Studies focus on its function in the Krebs cycle and its impact on cellular health.
Clinical Summary
IDH is an endogenous mitochondrial enzyme produced by all cells; supplementation is not standard clinical practice since the body synthesizes adequate amounts. However, genetic IDH mutations are associated with certain cancers and neurological diseases. Research into IDH modulators focuses on cancer therapeutics rather than nutritional supplementation for healthy individuals.
Nutritional Profile
- Not a dietary ingredient; functions as a catalytic enzyme. - Essential for the Krebs cycle and cellular respiration. - Involved in the production of NADPH.
Preparation & Dosage
Not available as a supplement. Consult a healthcare provider before use.
Synergy & Pairings
NADH, Alpha-Lipoic Acid, Coenzyme Q10
Safety & Interactions
As an endogenous enzyme, exogenous IDH supplementation has not been established as safe or effective for oral administration, as the enzyme would likely be denatured in the gastrointestinal tract. No documented interactions with medications or supplements exist for supplemental IDH products, which remain investigational and not approved for consumer use.
