NMN is the most direct way to increase NAD+ levels. This article describes what this does in the body, what human studies have shown so far, and what is still unknown, based on the current...

NR is the first NAD+ precursor with Novel Food approval in the EU and the only one for which direct tissue measurements in human skeletal muscle are available.

NAD+ decreases with age – but the most effective ways to counteract this process are not pills, but habits: exercise, sleep, and nutrition come first in the evidence.

TMG is not an NAD+ precursor, but a methyl group donor that supports the core of one-carbon metabolism – and thus one of the most often underestimated foundations for methylation, liver function, and cardiovascular health.

When mitochondria age, muscles, the immune system, and the brain suffer. A metabolite from the gut could reactivate the cellular recycling process. A summary of current human research, with an honest assessment of the limitations.

NAD+ is involved in energy production, DNA repair, and cell aging, and it decreases with each decade of life. NMN, NR, and NMNH are the main ways to influence this level. What research shows, what...
