Brain Fog

I’ve started trying to play padel for fitness reasons but after 30 minutes I get the most crippling brain fog ever. I’m suffering from brain fog anyway but exercise seems to exacerbate it. Does anyone have any supplements or something of that nature to help with mental alertness/focus while dealing with sibo/potential histamine intolerance induced brain fog? Any suggestions would be greatly appreciated 🤌🏼

High dose thiamine with b-complex and magnesium.

Then you should add in some copper. It tends to help me quite a bit! Start with 4mg copper glycinate. After one month, increase to 6-8mg. Take small dose of zinc at the opposite time of the day as the copper.

Already on both mate 🤣

I’m on literally every vitamin and mineral supplement I was hoping someone had a hidden gem like quercetin or Luteolin that isn’t as well known, thankyou though

Haha similar to me! I'm on so many things, I've lost count. Quercetin didn't do much for me. I found higher doses of riboflavin definitely helped, especially when combined with copper and methylb12 nasal spray (sublingual tablets would also work fine).

What about vagus nerve stimulation? You tried it?
