Scientific background

Independent research

NAD+ and NMN

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme in energy metabolism whose levels decline with age. NMN (nicotinamide mononucleotide) and nicotinamide riboside are precursors that the body converts to NAD+.

Research evidence

Independent research

NAD+ and NMN

A 2026 systematic review of trials of oral NMN found good short-term tolerability but no clear broad metabolic benefits, with preliminary signals on blood pressure and insulin resistance¹. Evidence for injected or nasal NAD+ products is very limited.

Evidence limitations

Independent research

This product does not state all ingredient amounts, so the doses used in research cannot be compared with what one serving provides.

No published study has tested this specific product; the research summarised here concerns the ingredient itself.

NAD+ and NMN

Trials are short and small; larger, longer trials are needed to confirm efficacy and long-term safety¹.

Safety & potential risks

Independent research

NAD+ and NMN

Short-term oral NMN was well tolerated in trials¹. Injectable NAD+ products are not quality-controlled medicines.
