About Betanin (betacyanin)
Betanin is the main red-purple pigment in beetroot and gives it its characteristic colour. It is a betacyanin (a class of betalain) with antioxidant properties. Betanin may also explain some of the performance and blood pressure benefits associated with beetroot juice.
No deficiency disease; not an essential nutrient.
No adverse effects from dietary intakes. Betanin can colour urine and stools pink/red (beeturia) — this is harmless.
None of the 1133 foods in the Nutriofia database currently have a recorded value for Betanin (betacyanin). This is a data gap to fill from published sources (USDA, CoFID, and analytical literature).
