Beeturia
betacyanin-colored urine
Beeturia is the passing of red or pink urine after eating beetroots or foods colored with beetroot extract or beetroot betalain pigments. The color is caused by the excretion of the betalain pigments, such as betanin.
The coloring is highly variable between individuals and between different feeding occasions, and can vary in intensity from light pink urine to strongly-colored deep red urine. The condition is benign and dissipates promptly with avoidance of beet foods. Beeturia occurs in about 10-14% of the public, with higher frequency and intensity occurring in people with iron deficiency, pernicious anemia or digestive diseases.
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 in foods of betalain-protecting substances, such as oxalic acid.
Beeturia is often associated with red or pink feces due to unabsorbed pigments ending up in feces.
Cause
The red color seen in beeturia is caused by the presence of unmetabolized betalain pigments such as betanin in beetroot passed through the body. The pigments are absorbed in the colon.
Begin with the source’s own compact description: “Beeturia” is betacyanin-colored urine. The dossier treats that line as a proposition to test through Beeturia, betacyanin-colored and urine, not as a finished interpretation.
Why this record matters
The phrase “betacyanin-colored urine” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Nov 3, 2025. The linked authority identifier is Q4880222. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
