Calcium Disodium EDTAPreservative
Generally well tolerated at the low levels used as a preservative and poorly absorbed orally, which limits systemic risk. But EDTA is a non-selective chelator: at higher chronic intakes it can bind and deplete essential minerals (zinc, iron) and has caused GI upset. Acceptable at trace preservative levels, but worth avoiding when a product also delivers minerals that EDTA could sequester.
