Hello. After eliminating all dairy, meat and sugars from my diet, -- and adopting a largely plant-based diet, I have noticed that my perspiration has a metallic smell. Additionally, I have taken a B-complex vitamin to compensate for the absence of B from meat sources, and since giving up dairy, I have notice that my urine is no longer yellow colored from the B vitamin, as it used to be. I don t know if these are related, but both changes came with my change in diet Can you tell me why this might be?
