So those seem to be the three forms that are found in animal food.Absorption of vitamin B12 is now known to be more complex than was once thought. In foods, methyl-, deoxyadenosyl-, or hydroxocobalamin are bound to enzymes in meat and other animal foods.
That I think has to do with the fact that clams, for example, contain way more B12 than beef, a lot more, like 15x more See here:I'm very interested in what info people can dig up here. I think @Freddd mentioned once that it is mainly adenosyl?
I wonder, too, about different meats. I find that I absorb very little B12 from beef, and a similar amount from pork (though it contains much less). Crab, and clams, OTOH, knock my socks off.

ETA: Sorry, should have read further down the thread. How do you know it's the B12 affecting inflammation and insomnia and not other factors in the various meats?
If only I had one. I've just never been able to tell those kinds of things so clearly, so I always wonder how people can tell.Well one never knows for certain, but it feels exactly the same as folate supps, so, based on stuff I have read here, I assume it's an uptick in methylation.
Other suggestions for interpretation are welcome, though!
