Oral semaglutide 50mg (Rybelsus HD) — need advice

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…

I do not accept that the fasting window is a minor inconvenience. Adherence data on daily orals with timing requirements is consistently worse than weekly injections, and a drug you take imperfectly is a lower dose than the one on the box.

Adding the numbers, since they settle part of this. For anyone assembling their own picture: Tmax is one to three days, terminal half-life about 165 to 170 hours, steady state at four to five weeks, and subcutaneous bioavailability near 89%. Those four numbers explain most of the questions people ask about timing.

Ask again with the specifics and you will get a better answer than this one.

There is a second half to this that has not been said yet. The dose-response is real but shallow at the top. Across STEP 1 and STEP 4 the gap between 1.7mg and 2.4mg is a couple of percentage points of body weight on average, and the average is carrying a wide spread — plenty of people at 1.7mg sit above the 2.4mg mean. If a dose is working and tolerable, "working" is the relevant variable, not "maximal".

A narrower follow-up, since the general answer is now clear:

How much of the oral variability is the SNAC absorption window and how much is dose, because the two get conflated constantly?

Reporting back.

I moved the tablet to the moment I wake up rather than trying to fit it around breakfast, and the difference in the following weeks was obvious. It was a timing problem, not a dose problem.
