Science /Healthy Aging 101

NMNH Technology

Understand the research behind NMNH.

UTHPEAK(TM) NMNH is included as an NAD+ precursor ingredient within a broader formula for cellular-energy metabolism, antioxidant support, and everyday healthy-aging routines.

Cell and animal research

Published studies have investigated NMNH as an NAD+ precursor in cells and mice. These findings do not establish a response in people taking this formula.

Read the 2021 FASEB Journal study

Measurements need context

A change in NAD+ is a research measurement. Its meaning depends on the dose, study population, tissue and method; it is not a guaranteed change in energy or healthy aging.

Understand the evidence

Know the finished formula

Review the ingredients and current label directions. Ingredient research does not establish a specific absorption rate, onset time or duration for NAD+ Supreme Rejuvenation.

View the formula and label

Explore the research, its limitations, and the ingredients in the formula.
