There are more than just pH considerations, but even so, remember that this is a general purpose delivery technology. Its designed to be effective and compatible with virtually any active ingredient or application. Some of the products may contain actives that only benefit from 1 or 2 of the delivery components, while others may surely benefit from them all.
Regardless, the whole design criteria of Tetrasorb was to ensure that all products derive at least some degree of absorption benefit, even future products that we have yet to conceive.
Your statement appears contradictory. Perhaps you simply failed to comprehend the concept? That's ok friend, I don't mind restating it for you. What the write-up claims is "a delayed-release effect". Now think about it, it takes longer to start absorbing (your words.) Isn't that the very definition of delayed-release? :shrug:
Of course it does. The stomach digests the gelatin that the capsule is composed of! That's the problem, but it seems you are still focused on pH. This is of far greater importance when considering the absorption kinetics of alkaloids and salts, but you are correct about the peptides and pro-biotics.
However, consider that the product is taken with a meal. Then what? What is the composition of that meal? What if a meal is not available and the user is forced to take the product on an empty stomach? What if the ingredient would actually benefit from an empty stomach but the user had to eat? etc, etc..
It obviously becomes a dynamic scenario very quickly, so this system was developed to make those considerations less relevant. Getting the active to the duodenum without confabulating factors, where it will then be dispersed in the jejunum helps to standardize the whole benefit. Making the delivery more consistent and effects more reliable, which fool-proofs results.
