Quick answer

NAD+ support from NMN raised blood NAD+ and improved walking distance and oxygen use in human trials. MOTS-c rose after exercise and improved running in mice, but no dose you can take has been tested in people.

Key takeaways

  • MOTS-c works as an exercise-linked mitochondrial signal tied to muscle glucose use, while NAD+ works as a cell helper that turns food into usable energy.
  • NMN improved power at the ventilatory threshold in runners, but the top aerobic measure called VO2max did not change.
  • Higher MOTS-c after an exercise routine went along with greater strength, better fitness and healthier blood sugar, insulin and cholesterol markers.

If you want more energy now, NAD+ support has the stronger human record. In human trials, the NAD+ building block NMN raised blood NAD+ and helped people walk farther and use oxygen better during exercise NMN walking trial NMN runners trial. MOTS-c rises in your body after exercise and helped mice run much farther, but no clinical method for giving MOTS-c to people has been developed exercise and mouse study MOTS-c review.

How do they work differently for energy?

MOTS-c is a small protein made inside mitochondria, the parts of your cells that make energy. Blood levels fall with age. In lab and animal work, it moves to the nucleus when cells are under stress and changes how muscle uses glucose MOTS-c review. You make more of it after exercise exercise and mouse study.

NAD+ is a helper molecule your cells use to turn food into usable energy. NMN is a building block your body turns into NAD+. In human trials, daily NMN raised blood NAD+ NMN walking trial. One acts as an exercise-linked signal studied mostly in animals, while the other acts as a cell energy helper you can raise and measure in people.

What did studies actually find in people?

People taking NMN walked farther in six minutes than people taking placebo NMN walking trial. In runners who trained regularly, NMN improved oxygen use and power at the ventilatory threshold, the point where breathing gets harder, but the top measure of aerobic capacity, called VO2max, did not change NMN runners trial.

For MOTS-c, human results show only what your own body makes. MOTS-c rose in muscle and blood after a bike workout exercise and mouse study. Higher MOTS-c after an exercise routine went along with greater muscle strength, better fitness and healthier blood sugar, insulin and cholesterol markers survivor exercise study. Reviewers note no clinical method for giving MOTS-c has been developed MOTS-c review. The strong treadmill gain comes from mice only, where MOTS-c treatment improved running performance exercise and mouse study.

Which makes sense if you feel drained?

If workouts feel harder and you feel drained through the day, NAD+ support is the practical choice now because it has direct energy results in people. MOTS-c stays in the watch-and-wait group, since results so far reflect your own MOTS-c around exercise rather than a dose you can take.

FAQ

Does NMN raise NAD+ levels in people?

Yes. Daily NMN raised blood NAD+ in human trials.

Did NMN improve top-end aerobic capacity?

In runners who trained regularly, NMN improved oxygen use and power at the point where breathing gets harder, but the top measure called VO2max did not change.

What happens to MOTS-c around exercise?

MOTS-c rose in muscle and blood after a bike workout. Higher levels after an exercise routine went along with greater strength, better fitness and healthier blood sugar, insulin and cholesterol markers.

Can MOTS-c be taken as a dose for energy?

No tested method for giving MOTS-c to people has been developed. Human findings so far reflect the body's own MOTS-c around exercise, not a dose you can take.
