Right, here goes. All my life I have not been overweight, my siblings are overweight. I have a problem absorbing B12 which in turn has made absorbing other food groups a problem, hence why I am not overweight. With me so far? Is it possible to derive enough B12 from ones own muscle mass, therefore keeping one at the very lower end of B12 range while not actually absorbing B12 from animal products? If beef is rich in B12, and cattle only eat the odd bug while digesting mountains of grass, where do they get the vitamin B12 from? I won't go on anymore as I will bore most of you, but if anyone can add to my pondering I would welcome it.

No. You cannot absorb B12 from your muscle mass to replenish your busy stores. What are your B12 blood levels?
Low B12 cannot cause you to not absorb B12 from animal products. But some things that cause low B12 can cause other absorption problems. But not enough to prevent you gaining weight if you eat a lot of calories.
Depression is a symptoms of B12 deficiency. Some people eat more when depressed and put in weight. Others lose their appetite.
Cows get their B12 from the bacteria in their gut. Not from bacteria, soil or faeces on their food. Your gut bacteria also produce B12. But they live further down the intestines from the place where B12 is absorbed. Cows have a different layout so they can absorb B12 from their gut bacteria.
Humans can absorb the B12 produced by their own gut bacteria, but only if those bacteria are incubated ina growth medium. That’s why some fermented foods like kimchi can contain B12, they’ve been contaminated with human shit.
Not sure kinchi contains b12... two types of seaweed are the only veg ever mentioned... and i read marmite’s b12 level night have been boosted by a decimal place error...
But in any case, whatever food source, if its malabsorption, jointpain , you’ll need injections of b12, (unless anyone can help me figure out reversing the malabsorption...)
Just in case FB's just put everybody off fermented foods 🤔😳
I take spoonfuls of sauerkraut every day - the only probiotic that finally settled years of digestive problems
I do inject every other day. It's that I can now tolerate gluten, milk, cheese, meats, all of which used to cause me many IBS type problems. This was before I found out that my b12 was low, it was measured for the first time after I had been supplementing for a month and was 178, again after two months and was 452, but though some b12 difficient symptoms went many remained. My folate levels are fine. I started to SI and my levels are to quote "too high to measure" never felt better, unless I don't SI then I get some nerve pain and involuntary movements. Recently tried milk, then later gluten, then meat, cheese, all of which I can now digest without a gut centered problem. With all this new found food freedom, I am putting on weight though!!
Cows have a very large stomach with 4 sections and large intestines. They Eat a lot of grass that is then highly fermented by bacteria into a large amount of essential fatty acids that they use for fuel. They also spend 70% or so of their day eating.. Its pretty crazy how different the digestive systems can be in animals.... too bad grass eating wont work for us....lol
