Can drinking green tea cause bright yellow urine?

Yes, drinking green tea can cause bright yellow urine. This is because green tea contains a compound called riboflavin, also known as vitamin B2. Riboflavin is a water-soluble vitamin that is excreted in the urine.

How riboflavin affects urine color:

* Riboflavin is a yellow-colored compound.

* When it's present in high concentrations in the urine, it can give the urine a bright yellow color.

Other factors that can affect urine color:

* Hydration: Dehydration can make urine darker.

* Medications: Some medications can change urine color.

* Food: Certain foods, such as beets and blueberries, can temporarily color urine.

Note: Bright yellow urine due to green tea consumption is usually harmless and does not indicate any health problems. If you notice any other changes in your urine color or frequency, consult a healthcare professional.
