B12 is lost in food in the GI tract when the person is dependent on passive absorption. (i.e. the intrinsic factor is broken or not present). If not taken on an empty stomach the small absorption of B12, blocked or greatly minimized.
This same recommendation is given for RX drugs that are given in microgram amounts --meaning thyroid hormones, and digoxin.
The study I put up often, and is on our B12 thread, showing 13mcg into the blood from a 1000mcg oral dose, used empty stomach to get those results.
It can be a shame, to go thru all the hoops of diagnosis of low B12, etc, and then take the needed B12 the wrong way and fail at that level.

Mrs. D. I take 5000 of the Methyl B-12 every day in the morning. This means I'm only getting 65 mcgs of the Methyl B-12? Didn't know it was that little. Do people ever take 50,000 every day (not that I'm doing that, just asking). Thanks much
