The Claim

Copper forms more stable complexes with citric acid (log β ≈ 9.5) than zinc (log β ≈ 7.5) under identical experimental conditions, indicating stronger binding affinity between copper and citrate ligands.

What the research says

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Copper sticks to citric acid much tighter than zinc does, like a stronger magnet holding on better, when you test them the same way.
