I can't say it helped or hurt. Basically, we baselined my mental capacity yesterday to monitor it going forward. The only problem was as of yesterday I felt 40% dumber than I did when I caught Covid 7 months ago. Definitely better than my primary physician who said "sure the memory problems with your covid probably is less than you are used to, but you are still very smart - wouldn't worry about it". I do he doesn't. I must say my new (Over the Counter) probiotic is very encouraging (VSL#3) is showing great improvements after 1 week. My gastric problems, gas, diarrhea, cramping, acid reflux and Covid Tongue (inflamed taste buds on the tongue) have significantly improved. I must admit I quit eating anything but yogurt and liquid nourishment after lunch so it might be a combination, but I am getting some sleep now. Not one to recommend cures over the internet but since it is an "over the counter" product and seems to be much higher rated by NIH than the brand-named ones - it's worth going online, making your own decision and checking in with your doctor. I was pleasantly surprised when my gastroenterologist finally recommended something specific. Do an internet search with the name of your probiotic with a comma and NIH. Then do one with VSL#3 and you can compare the two. First sign of relief in 7 months on any of the many symptoms.

I have all the symptoms of long covid. Started 7/2/22 for 3 weeks then bronchitis then sterp throat and sill all symptoms I have. 70 yrs old mighty hard to do most anything.
