I switched from injectable to oral semaglutide for travel reasons and the fasting window is proving harder to hold than the injection ever was.
So the question, as narrowly as I can put it: how much of the oral variability is the SNAC absorption window and how much is dose, because the two get conflated constantly.
Practical detail welcome, however dull — the duller the better.
Short answer first, then the reasoning. The OASIS programme put 50mg oral in the same territory as 2.4mg injectable — around 15% mean weight loss — but it needed a dose 20 times larger to get there because almost none of the tablet is absorbed. The dose numbers are not comparable across routes and quoting them side by side confuses people.
Happy to go further on any of that.

No disagreement with amsterdam_pete. One condition attached. Worth adding that the tablet is taken daily, so a missed dose costs far less than a missed weekly injection. That is a genuine advantage nobody lists.
That is the short version; the long version is somebody else's post.

This matches mine closely enough to be worth saying so. 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.

Adding the clinical framing, because it changes how the question reads. The mechanism and the magnitude are separate questions. Agreeing that something happens says nothing about whether it happens enough to act on.
