CoQ10
Coenzyme Q10 is a compound the body produces and also obtains from food. In supplements it is included for cellular energy positioning, which is why it appears in premium multis and standalone products alike. It is frequently paired with antioxidants and minerals rather than sold as a vitamin. If you see CoQ10 on a men's formula label, read it as an energy-support add-on and check the amount per serving, since inclusion alone says little about quantity.
