Is it normal to pee neon yellow?
Mostly.Normal for most people
Yes, neon-yellow pee is often caused by B vitamins, especially riboflavin, and is usually harmless. Some medications can do it too; dehydration tends to make pee darker yellow, not neon.
That highlighter-yellow color is often your body getting rid of extra B vitamins from a multivitamin or supplement. Some medications and strongly colored foods can change urine color, too, and it’s usually nothing to worry about.
If you haven’t taken anything that might explain it and the color sticks around, or you also have pain, fever, blood in your urine, or feel unwell, check in with a healthcare professional.
