Beeturia

Betanin, the beet pigment causing urine coloring
A selection of differently colored beetroot varieties

Beeturia is passing of red or pink urine after eating beetroots or foods colored with beetroot extract or beetroot pigments. The color is caused by the excretion of betalain (betacyanin) pigments such as betanin. The coloring is highly variable between individuals and between different occasions and can vary in intensity from invisible to strong. The pigment is sensitive to oxidative degradation under strongly acidic conditions. Therefore, the urine coloring depends on stomach acidity and dwell time as well as the presence of protecting substances such as oxalic acid. Beeturia is often associated with red or pink feces.
