I take this product everyday to save my vision
I get this product every month Because I ophthalmologist recommended it. It must be working because he says my degeneration hasn't progressed.

Works Well
I’m giving it a 4 because it is very chalky and leaves a residue in your mouth when you take it.

works for me
No noticeable side effects. It works well in combination with a separate pill containing dextromethorphan HBR. The dextromethorphan by itself doesn't work for me when my cough is productive (i.e., produces stuff). It contains no ingredients I don't recognize or consider unhealthy.
