I'm not a medically trained person and your B12 level although a bit low would be flagged as "Normal" but I wonder what sort of diet you have. Can you eat meat, fish, seafood, eggs, poultry and dairy products as it is from these foods that we obtain b12 naturally?
Folate is derived from leafy green vegetables, sprouts, broccoli, spinach, beans, peas asparagus etc and this and B12 help your iron to make read blood cells.
Certain medications such as antibiotics, antidepressants, antacids etc can affect absorption of B12
If you can't come off omeprazole , I think that you should self-inject . Some people can absorb B12 with sub-lingual tablets , and mouth spray . I can't but perhaps you can . It's work a try .
I think the range is something like >4 so that's not high
I've had P.A. for over 45 years and so am on permanent B12 injections and I have for more years than I can remember taken 1 – Folic Acid 400μg tablet as a "maintenance" dose and I'm wondering if you might benefit by taking a supplement. That strength tablet can be bought cheaply over the counter at any chemist.
You may want to talk to your doctor about treating your neurological symptoms by giving your B12 level a boost either by injections or supplements. He/she may try to shrug you off by saying your level is "Normal" but it's worth a try.
A lot of folk in this community self inject or use sublinguals to boost their B12. Personally I use a B12 methylcobamalin spray.
I wish you well and bid you goodnight
As you know Omeprazole is designed to block stomach acid production which is vital to digestion of food and this change alters the whole process of digestion resulting in malabsorption, and nutrient depletion such as B12, folate, calcium, magnesium, iron, zinc, chromium and Vitamin C.
Weaning yourself of PPI's after long term use is difficult and should probably be supervised by your GP - although I am always astounded that they are so ill-informed. You can probably find a few protocols for weaning yourself off them - here is one I just picked at random:-
