How to reduce ferrous ion interference during assay by HPLC?

My sample contains Ferrous ascorbate, Folic acid, Cyanacobalamin(Vitamin B12) and Cholecalciferol(Vitamin D3).
Is there any method to find assay values of these components by LC, when ferrous ascorbate is 100mg and folic acid is 1 mg and and Vitamin B12 is 7.5 mcg and Vitamin D3 is 1000 IU in 1 gm of sample.
