NADH (Nicotinamide Adenine Dinucleotide)
NADH is the reduced, active form of vitamin B3 (niacin) and a critical coenzyme in cellular energy production. It is essential for ATP synthesis in mitochondria and supports dopamine production, making it valuable for combating mental fatigue, enhancing alertness, and supporting motivation.

What is NADH (Nicotinamide Adenine Dinucleotide)?
NADH (Nicotinamide Adenine Dinucleotide + Hydrogen) is the biologically active, reduced form of NAD+, one of the most important coenzymes in human metabolism. Every living cell requires NADH for energy production, but the brain is especially dependent due to its enormous metabolic demands - consuming roughly 20% of the body's oxygen and a proportional share of its ATP.
In the mitochondrial electron transport chain, NADH serves as the primary electron donor, driving the production of ATP (adenosine triphosphate), the universal energy currency of cells. A single molecule of NADH generates approximately 2.5 molecules of ATP, making it the most efficient metabolic fuel source. When brain NADH levels are optimal, neurons have abundant energy for synaptic transmission, memory consolidation, and other cognitive processes.
Beyond energy production, NADH plays a crucial role in dopamine biosynthesis. It stimulates tyrosine hydroxylase, the rate-limiting enzyme in the conversion of tyrosine to L-DOPA and subsequently to dopamine. This connection to dopamine metabolism makes NADH particularly interesting for supporting motivation, alertness, and mental drive.
- ATP production: NADH is the primary electron donor in the mitochondrial electron transport chain, directly driving oxidative phosphorylation and ATP synthesis - the fundamental energy process for all brain functions.
- Dopamine synthesis: NADH stimulates tyrosine hydroxylase activity, increasing the conversion of tyrosine to L-DOPA, the immediate precursor to dopamine. This supports motivation, mood, and cognitive drive.
- Antioxidant activity: NADH acts as a potent intracellular antioxidant, directly scavenging free radicals and regenerating other antioxidants such as glutathione and coenzyme Q10.
- DNA repair: NAD+ (the oxidised form, in equilibrium with NADH) activates sirtuins and PARP enzymes involved in DNA repair, supporting genomic integrity in neurons.
- Nitric oxide production: NADH supports nitric oxide synthase activity, promoting healthy cerebral blood flow and oxygen delivery to the brain.
- Typical dose: 5-10 mg per day for general cognitive support and energy
- For mental fatigue: 10-20 mg per day
- Chronic fatigue research: Studies have used 5-20 mg daily with positive results
- Timing: Best taken first thing in the morning on an empty stomach, at least 30 minutes before food
- Sublingual forms: May offer better absorption by bypassing stomach acid degradation
NADH is sensitive to light, heat, and stomach acid. Enteric-coated tablets or sublingual forms are preferred for optimal bioavailability. Store in a cool, dark place.
- Side effects: Generally well tolerated. Occasional reports of mild nausea, headache, or gastrointestinal discomfort.
- Overstimulation: Some individuals may experience jitteriness, anxiety, or insomnia if taken later in the day. Morning dosing is recommended.
- Drug interactions: No major drug interactions reported, but those on medications for Parkinson's disease (which affect dopamine) should consult a doctor.
- Pregnancy: Insufficient research on supplemental NADH during pregnancy. Consult a healthcare provider.
- Storage: NADH degrades rapidly when exposed to heat, light, or moisture. Quality and bioavailability vary significantly between products.
NADH supplementation is generally considered safe for healthy adults. Product quality matters significantly - choose reputable manufacturers with stability testing.
Natural Sources & Forms
- Red meat: One of the richest dietary sources of NADH precursors
- Poultry: Chicken and turkey contain moderate amounts
- Fish: Particularly tuna and salmon
- Mushrooms: Contain small amounts of NADH
- Yeast: Brewer's yeast and nutritional yeast are notable sources
- Supplements: Available as enteric-coated tablets, sublingual lozenges, and capsules. Stabilised forms (such as PANMOL NADH) are preferred for shelf stability and bioavailability.
