So I did mini gastric bybass 4 years ago and I need to be on lifelong supplements and vitamins. I noticed that any supplement causes me brain fog and after quitting all my vitamins for a while the brain fog got way better and I could talk clearer and my personality came back. But now my hair is falling a lot and I’m having a lot of deficiency symptoms. Can someone please tell me how to balance that and if there’s any good multivitamin that wouldn’t cause that I’m so lost and I would really appreciate help. I tried many but they all cause the same thing
