My doctor put me on her protocol. I took phosphatidyl Choline (PC) for a year. PC cleared up my brainfog, they use this for dementia. I bought my PC from bodybio.com it's not cheap I think that I was taking three softgels three times a day. Sometimes when I feel brainfog coming on I'll order a bottle and it clears it up. Does nothing for energy. I also had Gluthoine pushes at the same time.
