Bright yellow urine is a sign of excess B-vitamins in the body, including B-2 and B, although this condition is harmless. Taking B-vitamin supplements can lead to urine of this color. The yellow color darkens as the concentration of the urine increases. Concentration refers the proportion of waste products to water. The urine darkens as the concetration increases, because the body takes in less fluid. This also happens if fluid is lost by other means, such as sweating. People use the yellow in urine to indicate fluid balance in the body.
Urine color is also a reliable way to monitor hydration levels during exercise. The yellow color in balanced urine comes from urochrome, a waste product that comes from the breakdown of hemoglobin. Hemoglobin is the protein in red blood cells that enables oxygen to travel around the body.
Red blood cells are renewed in their millions every day, so the body needs to break down old cells. The urochrome from this process ends up in the urine as a yellow color. While bright yellow urine does not necessarily indicate dangerous health issues, it is important to keep a close eye on the color of urine.
