A scoring model you can audit, line by line.

The bar for recommending differs by nutrient. One threshold used to gate all thirty-two identically, so vitamin A and vitamin C were judged the same way. They should not be. Too much protein is harmless; vitamin A at a ten per cent shortfall is not worth taking, because retinol accumulates and nothing is gained above requirement. A product is recommended for a nutrient only where correcting that nutrient is actually worth it.

This sits on top of the upper-limit ceiling rather than replacing it. Nobody was being overdosed before; the ceiling already refused any dose that would breach a tolerable limit. This is the separate question of whether a modest gap is worth supplementing at all.
