I've had a look online and it says somewhere that covid depletes b12 from your system.
I've recently had my injection but had covid after that and I'm really struggling with tiredness. I've dozed off three times during the day and that never happens.
Just wondering if anyone on here has had the same, I'm curious about whether it's just normal post covid or if this is a known thing.
I got given my covid injection as a priority because of b12, I'm starting to wonder if I ought to be asking for a refill
