Just some educated guesses from me. I think it's safe to assume that the proccessed liquid will have an osmolarity higher than seawater to initiate and maintain forward osmosis as the output volume increases and dilutes the syrup. Depending on what reference you consult, seawater's osmolarity can vary from roughly 1,000-2,500 mOsm/L so the processed liquid's osmolarity probably falls roughly into this range, too. Just for reference, the body's normal osmolarity is roughly 300 mOsm/L.


In the FAQ for this product, it already advises users to sip the processed liquid, and to space out the sips, so even when fully loaded, the manufacturer already knows the processed liquid is concentrated enough to potentially cause dehydration, so I think it's safe to assume (there I go assuming again) that the answer to your question is "yes". At least, unlike sipping seawater and getting all that extra salt, the high osmolarity of the processed liquid is primarily from sugar and not salt, so at least your body can do something useful with the sugar.
