Boost cellular energy production and support heart health with bioactive vitamin B3
NADH (nicotinamide adenine dinucleotide, reduced form) is the active coenzyme form of vitamin B3 (niacin) and is a direct participant in the mitochondrial electron transport chain, the final step of cellular energy production where ATP is generated. Each capsule provides 1mg of NADH. Unlike standard niacin or niacinamide supplements, NADH does not need to be converted before it can participate in energy metabolism. It is immediately available to donate electrons for ATP production.
NADH is particularly relevant for conditions involving mitochondrial dysfunction and cellular energy deficits, including chronic fatigue, jet lag, cognitive decline and recovery from illness. It has been specifically studied in chronic fatigue syndrome, where it may help supports cellular energy production that is impaired. NADH also plays a role in neurotransmitter synthesis, contributing to the production of dopamine, noradrenaline and serotonin. The vegetarian capsule shell makes this suitable for most dietary requirements.
Key benefits:
- Cell energy from active B3 coenzyme
- Heart health and better cholesterol
- DNA repair and cognitive support

Directions for use:
Take 2 capsules 1 to 3 times per day with meals, starting with the lowest dose and gradually increasing if required.
Begin with 2 capsules once daily (2mg) and increase to 2 capsules twice daily (4mg) or 2 capsules three times daily (6mg) based on response. Some practitioners recommend taking NADH on an empty stomach for maximum absorption, particularly when using it for energy support or jet lag.
NADH is a component of several Nutri Tailor bundles including Energy Optimiser, Fatigue Recovery and Frequent Flyer. When used as a standalone product, it provides targeted mitochondrial energy support. Allow 2 to 4 weeks to assess the energy response at each dose level before increasing.
