BioCoenzymated Riboflavin 5'-Phosphate

When I take B2, my left ear clogs.

When I take BioCoenzymated Riboflavin 5'-Phosphate, my left ear does not clog. However, I get a really bad feeling on the back of my tongue. Is this candida dying? Or is my liver not keeping up and stuff is erupting onto the back of my tongue?
