What Could Be Causing Your Urine to Smell Bad?

11. Medications and Supplements

Just as the foods you eat can influence the aroma of your urine, so too can various medications, vitamins, and supplements. It's not uncommon for people to notice a change in the smell of their urine after starting a new medication or supplement regimen. B vitamins, for instance, are notorious for turning urine a bright yellow color and giving it a distinctive strong smell. This is because t[T]he body excretes excess vitamins that it cannot absorb, which can alter the odor of your urine. If you've noticed such changes, it might be worth discussing with your healthcare provider, especially if the new scent is bothersome or persists.
