It doesn’t say on the box but I would assume these are in the reduced form as they are likely made from sulphates like ferric sulphate and manganese sulphate, these are reduced forms and they are chelated with edta.

The reduced elemental signs are Fe++ or MN ++. If it said iron rather then Fe I would be suspicious.

The edta chelates are cheap synthetic ones and they can chelate other nutrients in the plant such as calcium.

A better chelator choice is an organic acid like citric acid or an amino acid.

These guys make some good stuff that is properly chelated and should be available in Italy
