I guess it might be but I've noticed a lot of drinks now are loaded with vitamins but B vitamins should be water soluble and come out in the urine. But maybe we have a kidney issue where it's just not filtering enough of the extra B vitamins? or it's the food we eat. But I did notice some strange after effects from COVID as well. I also now have strange nerve things where I'll scratch my leg and I'll feel a nerve tingle on my stomach always in different areas very strange the Neurologist said it was probably from diabetes but didn't sound like he could say for certain. but anyway just dealing with it the best I can. Good luck moving forward.
