Mine does. I thought the cat was pissing in the loo I think it's when I take too much mB12 without taking Phosphatidylserine afterwards. But really, I don't know much so would love to hear your random thoughts on this. It lasts for about a day. Hence connected to my food, I think. It's when I eat protein. I take quite a bit of mB12 and methylfolate with protein. Maybe 1/3rd of a pill. I'm supposed to take Phosphatidylserine after this but sometimes I forget. It's needed because otherwise the cells fill up with ammonia. They might overspill into the urine? I'm homozygous for MTR/MTRR; VDR Taq and have that weird hetero-combination of MTHFR A1298C and MTHFR C667T Nothing much on the detox panel, just CYP2C19*17 homozygous I avoid sulphurous foods. Any thoughts or shared experiences appreciated.
