My son has smelly urine..? - what vitamins make smelly urine

Its really bad. Only 1 glass of water and Yuce during the day. Put the milk in the morning and evening. I know that the bad smell has to do with how the host and the amount that you will get a lot. Is there anything else I should do? As he held various food, or they have not a vitamin?
