Can lemon in tea cause urine to be bright yellow?

Yes, lemon in tea can cause urine to appear bright yellow due to the presence of certain compounds, such as vitamin C (ascorbic acid) and other pigments found in the lemon. When consumed in significant amounts, these compounds can lead to changes in urine color. Additionally, dehydration can concentrate urine, making it appear more vibrant. However, bright yellow urine is typically not a cause for concern unless accompanied by other symptoms.
