Just got my NHS blood test results back and frustratingly the results of B12 and Folate are JUST within the normal range. They are as follows:
Serum vitamin B12 level 203 ng/L [197.0 - 771.0]
Serum folate level 4.9 ug/L [3.89 - 26.8]
Yet I am still having serious symptoms: daily nausea, dizziness, constipation, lack of appetite etc.
Doctor says results normal and so will only prescribe medication for constipation. Any advice?
