Abstract
Nicotinamide adenine dinucleotide (NAD) exists in two forms: the oxidized NAD+ and the reduced NADH. The conversion of NAD+ to NADH is a fundamental redox reaction in cellular metabolism, where NAD+ accepts electrons and a hydride ion during processes like glycolysis and the citric acid cycle. This transformation enables NADH to carry energy to the electron transport chain for ATP production. As a leading NADH powder raw material manufacturer, we provide high-purity NADH raw material for bulk and wholesale applications in dietary supplements, supporting energy metabolism and overall cellular health.

What Are NAD+ and NADH?
NAD+ (nicotinamide adenine dinucleotide) is an essential coenzyme found in all living cells. It acts as an electron carrier in redox reactions, alternating between its oxidized form (NAD+) and reduced form (NADH).
- NAD+ is the oxidized state, ready to accept electrons.
- NADH is the reduced state, carrying high-energy electrons and a hydrogen ion.
This cycle is critical for energy production, as NADH donates electrons to generate ATP, the cell’s primary energy currency. Maintaining optimal NAD levels supports mitochondrial function, DNA repair, and metabolic efficiency.
The Biochemical Process: How NAD+ Becomes NADH
The conversion of NAD+ to NADH occurs through a reduction reaction in catabolic pathways.
In dehydrogenase-catalyzed reactions, NAD+ accepts a hydride ion (H⁻, equivalent to two electrons and one proton) from a substrate, while a separate proton (H⁺) is released into the solution. The chemical reaction is:
NAD⁺ + 2H⁺ + 2e⁻ → NADH + H⁺
This primarily happens in:
- Glycolysis: In the cytosol, where glucose breakdown produces NADH.
- Citric Acid Cycle (Krebs Cycle): In the mitochondria, generating multiple NADH molecules per glucose.
- Fatty Acid Oxidation: Further contributing to NADH production.
The process is reversible, allowing NADH to oxidize back to NAD+ in the electron transport chain, producing approximately 2.5-3 ATP molecules per NADH.
This efficient cycling underscores the importance of NAD in sustaining cellular energy.

The Role of NADH in Energy Production and Health
NADH plays a pivotal role beyond energy transfer:
- It supports mitochondrial ATP synthesis via oxidative phosphorylation.
- It contributes to antioxidant defense and cellular repair.
- Balanced NAD+/NADH ratios regulate redox homeostasis, influencing aging, metabolism, and immune function.
Research indicates that declining NAD levels with age may impair energy production, leading to fatigue and metabolic issues. Supplementing with stable forms of NADH has shown potential benefits in enhancing cellular energy, cognitive function, and stamina in preliminary studies.
