Can a 5-Day NAD+ boost improve health markers? small study investigates
NCT ID NCT07336836
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase trial tested whether a 5-day course of an oral NAD+ supplement (LNAD+) could raise NAD+ levels and change biological markers in 60 healthy adults aged 45-75. Participants took either the supplement or a placebo, and researchers measured NAD+ in blood cells and circulation, along with safety and metabolic effects. The goal was to gather initial data on how this supplement might affect wellness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- LathMized TM NAD+ (LNAD+) dietary supplement
- What this could lead to
- If successful, this study could show that oral NAD+ supplements safely raise NAD+ levels and improve certain health markers, pointing toward potential benefits for aging or wellness.
- What could go wrong
- This is a very small, early-phase trial in healthy people, so results may not apply to broader populations or those with health conditions. The 5-day treatment period is too short to assess long-term effects or risks.
