Diet  is  a factor.  B vitamins, such as riboflavin (B-2) and cobalamin (B-12), are also known for causing fluorescent yellow-green urine. If you take supplements or multivitamins, they may be the source of your brightly colored urine.Meal replacement shakes, which are also fortified with B vitamins, can have the same effect.Excess beta carotene or vitamin C may lead to urine that’s dark yellow or orange. Beta carotene, which is converted to vitamin A in the body, is found in yellow and orange foods such as carrots and sweet potatoes.


If you don’t properly hydrate after a workout, it can also lead to dehydration and darker urine. Extreme exercise without proper hydration can cause a serious condition that leads to muscle breakdown.This can cause severe muscle pain along with cola- or tea-colored urine. If this occurs, you should seek immediate medical attention.

Over-the-counter and prescription medications can also make your urine bright or more vivid. This includes antibiotics, laxatives, and certain chemotherapy drugs used to treat cancer.For example, the medication phenazopyridine (Pyridium) is commonly used to treat the discomfort associated with urinary tract infections (UTIs). A common side effect of its usage is orange-colored urine.Other medications such as rifampin may also harmlessly stain the urine a bright orange color.

Besides,changes in the color of your urine could be a sign of troubles with your kidney, liver, or bladder function. If your urine becomes cloudy or develops a strong odor, you may have a bladder or kidney infection.

This is especially true if you’re having any symptoms of these infections, such as pain when urinating, fever, vomiting, or back pain.
Normally, bright yellow urine is normal. If you worried, you could have a urine test to find out.
How bright is it?

Are you taking any new supplements? It's probably something you take, I had similar experience. I once had a complete nutrition from GNC, and the urine turns to a strange color, maybe yellow, I don't remember precisely.
Thank you for responding
I drink water through out the day
I have not taken anything new

I don't think it means anything abnormal. If you are really concerned, just do a urine test. Simple and informative.
Too many boost shakesp
I have stage 4 cirrhosis of my Liver. I have bright yellow urine. this is new. Is this a problem?
it is hard to say you have kidney problems only due to the yellow urine.  you can do a urine test to see whether it is normal.
