The reasoning for the reformulation makes sense but I still don’t think that fully answers the question.
There are really only 3 reasons why the price wouldn’t change if there is one less (i.e. -25% less) primary ingredient:
- The wholesale costs of all the ingredients (or cost of production process) went up so we’re seeing that pass through
- Mix: The relative mix of ingredients changed. In this case, one of the higher cost ingredients now makes up a larger share of the total formulation & takes price up
- Biotest is just leaving the price the same and capturing the extra margin.
Its fine if the answer is (at least in part) #3 - but just say that. I will probably use the product anyway b/c if it compares to the old formula the value (to me) is still > price.
