On 25mg oral, four months in, and my results are closer to the low-dose injectable arm than to the numbers being quoted for 50mg.
So the question, as narrowly as I can put it: whether the fasting requirement is as strict in practice as the label implies, and what people actually see when they get it wrong.
Not looking for reassurance. Looking for the part I have got wrong.
Short answer first, then the reasoning. Oral semaglutide is absorbed in the stomach with the help of SNAC, which locally raises pH and protects the peptide long enough to cross. That mechanism is fragile: bioavailability is roughly 1% and highly sensitive to gastric contents, so a mouthful of coffee genuinely changes the exposure. This is why the label wants 30 minutes and no more than half a glass of plain water.
Ask again with the specifics and you will get a better answer than this one.

No disagreement with kate.chem. One condition attached. The absorption variability is real, but it partly averages out over weeks — the steady-state trough is less erratic than any single day would suggest. Where it bites is in the first fortnight, when people conclude the tablet does nothing.
That is the short version; the long version is somebody else's post.

Can confirm the pattern hans_munich describes. Orforglipron is the more interesting oral story because it is not a peptide at all. Being a small molecule it does not need SNAC, does not need the fasting window, and has oral bioavailability in the tens of percent rather than about one.
From the other side of the consultation, briefly. Whatever the answer turns out to be, the method for getting there is the same: state the assumption, do the arithmetic in public, and invite the correction. That is slower than asserting, and it is the only version that survives being wrong.
