Why does my urine go bright yellow when taking multivitamins?Updated 4 months ago

High-dose multivitamins such as ULTRA B ACTIVE can turn your pee a bright, almost neon yellow colour. This is very normal and the most common culprit is vitamin B2, also known as riboflavin, which is found in ULTRA B ACTIVE. The neon colour in pee is just a harmless sign that your body is removing the excess it does not require. This is a good sign, it means you have adequate levels and the excess is exiting your body and mixing with your pee.
