I'm pretty sure Nano Soma "cured" my CFS that I had for over 20 years. It's hard to know for sure because I'm always doing SOO many things for my health, and it wasn't quick, it took a few years, but I know it was the Nano Soma that healed my mitochondria. I started taking it in the fall of 2021 and by the fall of 2023 (and maybe sooner but that was when I really tested myself) I no longer had Post Exertional Malaise. So grateful for Nano Soma!
