My brother started acting a little weird the past couple of weeks. I'm thinking it's because he stopped taking his vitamins and went back to his old habits. He still works and can do all his normal things.

I noticed that he has slow response when I'm talking to him. It takes him a few sec to respond to a question. He's telling me that there is something going on in his brain but he can't explain it. He has no panic attacks or anything. I read that Vitamin B6 is good for the brain support? He started taking GABA last night. Any suggestions guys?

THANK YOU
