Query: NOT AS ADVERTISED - CONTAINS NO IRON

This product is sold by Amazon as "Stresstabs + Iron", and stickered with a barcode label that also says "Stresstabs + Iron". However, comparing the ingredient list on this package against the ingredients of my last order of Stresstabs + Iron shows this "reformulated" product contains NO IRON and NO Vitamin E. But it contains a couple of new herbal extracts that I have never heard of.Had I known it contained no Iron and no Vitamin E, I would never have bought it.
