Is it possible i have a b12 deficiency?
I have been dealing with chronic fatigue,brain fog,stomach issues,lack of motivation,shortness of breath,depression for about 2.5 years now. i recently got a test for b12 deficiency and had a level of 314 which i was told was normal. looking around online i see people saying you can have symptoms in the lower end of the normal range and was wondering if a b12 deficiency could be the cause of my symptoms. i have been tested for numerous other things like hypothyroidism,low testosterone,diabetes and all tests have come back negative.
