Any kind of yellowish tint in your urine is because you do not drink enough water. Absorbing a multi-vitamin floods your body with vitamins all at once, causing you to dehydrate a bit in order to absorb them. Just up your water a bit and your piss should be clear again

Excess Vitamin B2 does not 'tint' your urine, it turns it NEON yellow. And it is not because he isn't drinking enough water.

Large doses of vitamin B2 (riboflavin) will result in bright yellow urine due to the vitamin producing yellow fluorescent substances. While this is not harmful, it does indicate that you are probably consuming more vitamin B2 than your body can utilize at one time. 5-10 mg per day of vitamin B2 is adequate for general supplementation, although higher doses are not associated with any toxicity or side effects. The only contraindication to high doses of vitamin B2 is if you have cataracts. If so, you should limit your daily intake of B2 to 10 mg.

Rather than discontinue your vitamin supplement, you may want to take the daily amount divided in several doses spread out over the day to make better use of the B vitamins in it. Vitamin B2 is required in the body to convert carbohydrates into energy in the cells, to process proteins and fats, to convert vitamin B-6 and folic acid to their active forms and to assist with the regeneration of glutathione (an antioxidant), and along with the other B vitamins is a vital nutrient.

I agree. Nothing to do with hydration. Since when do vitamins double as a diuretic.
