01 / What is it?
What is it?
NAD+ is a tiny helper molecule that is already inside all your cells. Your body uses NAD+ to turn food into energy so your muscles, brain and heart can work.

NAD+
Why do people find it interesting?
NAD+ is involved in cell energy, DNA repair and many other basic cell processes. This is why it is often discussed in relation to ageing, energy and mental performance. However, broad 'anti-ageing' claims go beyond what has been clearly proven in humans.
What might you notice?
Some people report feeling more alert, focused or energetic after using NAD+, or products intended to raise NAD+ levels.
What happens in your body?
NAD+ helps cells make and use energy. It is also needed by enzymes involved in DNA repair and the cell's response to stress.
How long does it work?
There is no single reliable timeline for when a person will notice an effect from NAD+ injections or supplements. This can vary by product, route of use and individual response.
Keep the context
Important to know
NAD+ injections may cause temporary stinging or burning at the injection site. This can be influenced by the acidity (pH) and concentration of the solution, as well as individual sensitivity. When NAD+ is given intravenously, especially if it is administered quickly, some people may experience temporary nausea, headache, dizziness or flushing.

Dose information from the guide
Some reported protocols begin with around 30 mg of NAD+ per administration. If this is well tolerated, with few or no unwanted effects, later protocols may use amounts of up to 100 mg per administration. Reported protocols describe administration one to a maximum of three times per week.
