@clynnp Currently, I'm taking Prohealth Longevity, Liposomal NMN Pro 300 and Qunol Ultra CoQ10. That's working good for me but after I'm done with that, I'm going to try Life Extension Optimized NAD+ NMN. I would stick with the Prohealth but my brother sent me the Life Extension brand-so a freebie, which I can't resist:).

That's interesting that Doctor's Best combined the NMN and CoQ10. The 2 work synergistically in ATP production. That said, I noticed an improvement in energy and endurance when I was taking just the NMN. I'll take a look at the Dr's Best as well. Life Extension NMN adds reveratrol, bio-quercetin, and fiestin-so another synergistic mix.

I hope it helps. There's always the placebo effect. In a few weeks, I will post my friends (she has BE, MAC, and COPD) experience-hopefully it will help her as well.
