Group ADI for phosphates, expressed as phosphorus.

Flour, dairy, supplements.
What the ADI means in practice
2 400 mg per day is the figure for a 60 kg adult — multiply or divide for your own weight. EFSA derives ADIs with a safety margin of typically 100×, and they describe daily lifetime intake. A single day above the ADI does not translate to harm; a permanent diet above it is what the limit exists to prevent.
This page describes the general scientific position. Allergies and sensitivities are individual: if your body disagrees with an additive, avoid it regardless of any ADI.
