Clozapine is actually an atypical antipsychotic (newish generation)- and is least likely to produce undesirable D2 antagonist adverse effects (extrapyramidal kinesic effects , elevated prolactin).
Lurasidone is more than likely the reason for the elevated prolactin.
In any case I wouldn't start the any prolactin control supplements until you have spoken with your treating physician. The old school of thought is that pro-dopaminergic compounds can exacerbate psychotic illness- on paper L-Dopa has direct pharmacodynamic interaction. There is a actually a current trial specifically testing L-Dopa as treatment for EPSE in those treated with antipsychotics- their hypothesis is that it may work to control these.
In any case- given Clozapine alone requires ongoing monitoring- you don't want to be messing with your treatment, especially is it is stabile, unless your treating physician is aware and can monitor it.
