This study aims to understand how healthy younger and older adults use two forms of vitamin B3, Nicotinamide Mononucleotide (NMN) and Nicotinamide (NAM), to create NAD+. NAD+ is a natural substance vital for energy and other important cell processes. Researchers want to see how these substances are absorbed, processed, and how they increase NAD+ levels in different parts of the body. You can join if you are a healthy adult, male or female, aged 18-40 or 65 and older, with a body mass index (BMI) between 19 and 35, and no major health issues. Success for this study means understanding how these NAD+ precursors are used by the body, measured by the amount of labeled NAD+ in your blood over 14 days. The current status of this study is unclear.

Study design

This is an interventional study planning to enroll 32 healthy adults. Participants will receive either Nicotinamide Mononucleotide (NMN) or Nicotinamide (NAM).

What's involved

You will take NMN or NAM by mouth every day for 14 days. Researchers will collect blood, urine, and stool samples during this time.

Compensation

Not stated in the trial record.

Follow-up

Your NAD+ levels in peripheral blood will be measured during the 14-day study intervention period.
