I don't see much bang for the buck here. Two of the products are nothing but algea, so why the two separate products?
Two of the products are probiotics, acidophulis and bifidus, that really could be combined, and these two products both have algea too. So even if the microbes actually work at populating the gut, you're still buying two products that should be one. Definitely a company that's trying to get your money in any way it can. Doesn't speak well for their integrity.
