Ignore that label.... it is inaccurate. Manufacturers are not research people. Only about 13mcg are absorbed in the intestine from a 1000mcg dose, and if food is present it is absorbed into the food and not absorbed at all. B12 is very poorly absorbed in the first place and it needs all the surface area of the intestine to get thru. For many years oral was thought to NOT WORK... and only when studies were done was it found that a tiny bit can be absorbed under ideal conditions.
Certain drugs too that are given in microgram doses, require empty stomach. Levothyroxine and digoxin are a couple of examples.
