Take B-complex Vitamins
Another useful tip if you are about to have a drug test is to take some B-complex vitamins. In general, they can color the urine yellow. This gives it the look of being less diluted than what it actually is. Common options are vitamin B2 and vitamin B12. It is also possible to purchase complex multivitamins in the nutritional yeast or tablet form. The recommended dosage is between 50 and 100 mg. Avoid B vitamin supplements when you are breastfeeding or pregnant. Some people take vitamin B3 or Niacin for this purpose. However, there is no research that proves the effectiveness of this form. Make sure to discuss with your doctor before taking it. [5]
