Dear All. My recent blood tests showed I was in range but low for b12 and in range but very low for folate. On the advice of the very helpful seasidesusie I have been taking sublingual methalcobalamin b12 and Igennus super b complex. I started taking the b complex first (as they arrived first!) My wee almost immediately turned bright yellow and I ended up with bladder/Kidney infection a fee days later which was treated with antibiotics. I then read on other posts I should have started the B12 first which I did then added the complex a few days later. My bladder however feels like it's playing up again i.e. don't think it's an infection but I am weeing a lot & I feel some irritation. Do you think the b complex is the problem and if so can anyone recommend a way round this as I want to raise my folate level and have also read b complex needed to balance all the Bs when taking b12. I have Hashis btw.
