I have explored that website and read the 'info for health professionals'
It just confirms the nutritional plan I have been using for the last 3 years -
B vitamins and folate (especially B12)

When I felt I was at death's door a few years ago, I asked for a B12 deficiency test.
They give the result in a figure - mine was 460 which was described as 'fine' so no B12 available from NHS.

The NHS guideline as to whether B12 is supplied is based on the levels which produce pernicious anaemia, which I don't have.
I found that the Japanese regard any level below 1000 needs B12 supplementation.

I imported (at great expence) B12 lozenges which, dissolved slowly next to my gum daily, provide me with a higher dose than those infrequent injections that are given to pernicious anaemia patients.
This, along with other supplements and detoxing heavy metals, and a better diet, has improved my state of health by leaps and bounds.

If this latest research enables GPs to prescribe B12 more readily, I approve.
With cost cutting going on I doubt it will happen.

There is another problem - Codex Alimentarius - whereby some food supplements will be withdrawn from availabily.
I have an 18 months stockpile of the most vital supplements I need. After that who knows?
