Vitamins: It's not unusual or harmful to have deep yellow urine after taking multivitamins. Most vitamins are simply excreted in the urine if they exceed recommended daily doses. However some vitamins like D or A can be harmful when taken in massive doses. It's important to adhere to the doses recommended on the label of legitimate preparations. You can get advice from your pharmacist if you're unsure.
