They should do very well. Their business model wherein the main product is compartmentalized from various subproducts, each of which has its own identity, is sage and will allow them to use these compartments as building blocks to new products or to offer their purchase individually in the future.
Also, briefly, it seems to me like they were pretty diligent to inform the public of possible interactions and contraindications on the product profile page. I don't know much about other supplement so maybe this level of attention is the standard nowadays, but it seemed to me like they were being fairly responsible. And this always bodes well for any business.
Anyway, good luck to them.
