What it is

NAD+ is a helper molecule made from vitamin B3 and used in hundreds of chemical reactions.

How it is thought to work

It shuttles electrons in mitochondria and fuels repair enzymes such as sirtuins and PARPs.

How it works · Mitochondria
Your cells' power plants
Mitochondria turn food and oxygen into ATP, the energy currency every cell runs on.

Animations simplify biology for teaching. They are not a claim that this peptide works this way in people.

What the research shows

Precursors such as NR and NMN reliably raise NAD+ levels in people. Clear benefits on hard health outcomes have not been shown yet.

Safety and considerations

IV infusions can cause flushing, chest tightness or nausea if given too fast. Sterile preparation matters.

Our position

Offered thoughtfully as part of our IV layer, with honest expectations.
