NAD+ is a coenzyme found in every cell and used in energy production and cell repair. NMN is a smaller molecule the body converts into NAD+. Human trials show NMN supplements can raise blood NAD+ levels, but evidence for wider benefits is limited. Research on taking NAD+ itself by mouth is even more limited.

Liposomal glutathione wraps glutathione in tiny phospholipid bubbles to help it survive digestion. Both liposomal and standard oral glutathione have raised body glutathione levels in small human trials, but no large study has compared them head to head. Liposomal may suit people who want a lower dose or a liquid, but the evidence is still early.

Coenzyme Q10 is a compound your body makes to help cells produce energy, and it also works as an antioxidant. Levels tend to fall with age, and statins can lower blood levels. Research on supplements for statin-related muscle aches and heart failure is mixed, so it suits some people more than others.
