Does biotin change your urine? “One of the effects of biotin is that it helps turn the carbohydrates, fats, and proteins in the food you eat into the energy you need.” Because it’s water-soluble (meaning it dissolves in water), excess biotin isn’t stored in your body; it actually just flushes right out of you when you pee.
Can too much biotin make your pee yellow? Bright yellow urine is common when taking a vitamin B complex, specifically due to the B2 vitamin, also known as riboflavin. In fact, “flavin” comes from the Latin “flavus” which means yellow.
Can vitamins change urine color? High-dose vitamins can turn your pee a bright, almost neon yellow color. The most common culprit is vitamin B2, also known as riboflavin, which is found in most multivitamins. The neon color in pee is just a harmless sign that you’re taking more than your body needs, and the excess is mixing with your pee.
