What is NADH? The molecule that powers your cells and your mind

In the world of cellular health and energy, few molecules are as essential – yet often overlooked – as NADH. NADH (Nicotinamide Adenine Dinucleotide + Hydrogen) is present in every living cell and plays a central role in energy production, brain function, and healthy aging.

What is NADH?

NADH is the reduced form of NAD, a coenzyme involved in hundreds of biological reactions. NAD exists in two forms:

• NAD⁺ – the “empty” form that accepts energy

• NADH – the “charged” form that carries and delivers energy

Together, they help convert the food you eat into usable cellular energy.

How does NADH work?

Your cells generate energy through cellular respiration, a process that produces ATP (adenosine triphosphate) – the body’s main energy source. NADH acts as a transporter, delivering electrons to the mitochondria, the “powerhouses” of the cells.

Think of NAD⁺ and NADH like a battery:

• NAD⁺ is the battery being charged

• NADH is the full battery delivering energy

Without NADH, your body could not efficiently convert food into energy or support vital functions such as DNA repair, mental clarity, or muscle activity.

Why is NADH important?

NADH supports several key processes in the body, including:

• Cellular energy production

• Mitochondrial efficiency

• Mental clarity and cognitive function

• DNA repair and cell regeneration

• Enzyme activation

• Reduction of oxidative stress

Low NADH levels are associated with fatigue, brain fog, and accelerated cellular aging.

Who uses NADH supplements?

• Athletes

• Busy professionals

• Students

• People with chronic fatigue syndrome (CFS)

• Individuals looking to support brain performance

Potential benefits of NADH supplementation

Energy and endurance
NADH helps boost ATP production, increasing endurance and reducing fatigue.

Chronic fatigue syndrome (CFS)
Studies show that NADH (especially in combination with CoQ10) may improve symptoms and quality of life.

Mental clarity and cognitive function
NADH can support focus, memory, and mental energy – especially with aging.

Athletic performance and recovery
Animal studies suggest NADH may enhance physical performance and muscle recovery.

Heart and brain health
By reducing oxidative stress, NADH may support cardiovascular and neurological function.

Is NADH safe?

NADH is generally well tolerated. Rare and mild side effects may include:

• Muscle pain

• Insomnia

• Headaches

• Fatigue

To minimize risks, always follow the recommended dosage and consult a doctor if needed.

Summary

• NADH is the bioactive form of NAD that delivers energy to cells

• Supports cellular energy, focus, and brain health

• May improve fatigue, mental performance, and recovery

• Safe when used as directed, with minimal side effects

NADH = the full battery your body runs on
