Acetyl L Carnitine has made a significant difference in my fatigue and brain fog, which I had been experiencing for months since having covid. It took a couple of weeks to really feel the difference, but I now feel like I have my life back, though I still need to be careful with pacing and managing energy. I have even begun to gently exercise, which I had not been able to do for a long time. I have tried many ALC supplements, and these are the only ones that I can say have made a difference.
