Vitamin B2 or riboflavin turns the urine oragne/yellow again if diluting. You can get it from a straight up B-2 supplement, or as part of a multivitamin or B-complex. I don't recommend the multivitamin because you would have to take about 10 of those and if it has iron or some of the other minerals, it can upset your stomach. You want about 1000% the daily dose. If a lab was testing it for dilution they will look at specific gravity and creatinine clearance and won't care what color it is if the lab validity tests come back fine. Adding color is helpful for when visual is the validity test like a quick stick test or just to make you feel more comfortable.
