Does anyone know how long it takes to reach peak serum after ingestion? Also what search terms to use when trying to find this information. I have tried "bioavalibility" and "peak serum" but couldn't find what I was looking for.
Bioavailability is how much gets absorbed. Peak serum is probably what they call Cmax in studies. Bioavaiability for pyruvate and acetoacetate is high, as studies found that less then 0.1% of administered dose of calcium pyruvate gets excreted in urine/stool. So the rest is absorbed and I don't see why it won't be the same for EP/EA.
Another study with calcium pyruvate found that Cmax was achieved after 180min (3h). Half life for calcium pyruvate seems to be about 5 hours.
