If I have this right, floradix has more things of value in it--it's an extract of a variety of plants containing iron and other blood building nutrients. Chlorophyll, as the pp said, contains no iron. Both formulas provide highly bio-available nutrients, which is one reason they are so effective and work so fast.
I know people who like chlorophyll, but I prefer floradix because of the iron. No, it ain't cheap, but if you are anemic in pregnancy or after (such as from a hemmorhage), the cost of floradix is really pretty cheap considering it can mean the difference between a few weeks of recovery of your strength, and a few months--if we're talking about pp hemmorhage; and in the case of pregnancy iron-deficiency anemia, again you have to weigh the cost against how you feel and the speed of fixing a problem.
But it is also possible to take the same herbs at a lower cost--most people find taking floradix simpler, but it's all about the plants used in the formula, which you could make yourself, or purchase separately--maybe save some money that way.
