I have some interesting new developments.
Due to where i live, i haven't been able to cook beef liver for a year, so i took beef liver pills by ancestral supplements to manage my depression. However, i still have bad days and often feel 'bleh'. So those pills aren't cutting it.
I found three foods that actually have more B12 than liver:
Dungeness crab
Oysters
Clams
I ate 3 oz of oysters the other day and was bouncing off the walls with energy, like i was on drugs. It was more powerful than 4oz of beef liver. Too powerful! i'm having 1.5oz of oysters a day and i'm finally on an even keel and not in euphoria land.
But it still concerns me that i'm on a carnivore diet and getting basically 200% of my B12 intake through diet but still being deficient. How the hell?
I learned there's several things that can cause poor B12 absorption:
Low stomach acid ( i for sure have that )
Low/absent gut intrinsic factor ( not sure; sometimes due to an autoimmune disorder )
Transcobalamin deficiency ( can be genetic, not sure )
Gut bacteria issues ( almost certain i have this )
Heavy caffeine usage ( *raises hand* )
I'm going to experiment with curing the root causes above and see if i can naturally have high B12 levels without supplementing.
Will produce a video with my findings later.
Also my current girlfriend has OCD. I read a few papers showing that OCD can develop from a severe B12 shortage. I've had her eat some oysters and she had a similar mood effect and had 2 days where she didn't feel like washing her hands constantly.
She has serious digestive issues and is also has been on PPIs for a LONG time, which are famous for destroying B12 absorption.
It makes me wonder how many mental illnesses start in the digestive system.
