Everything you read here and at OBT ( on Vit D ) is based on just the most
recent knowledge. It cannot be perfect...cannot pertain to everyone.

You will see more stories now (like this week) that taking a simple multivit...
causes CANCER--- and from HARVARD no less. This is a response to the
desire by the drug companies to control the supplement movement. And also reflects the bias the medical community holds against anything that threatens its existence as a high price commodity (which millions here can no longer afford).

So if you can control your symptoms for 9 cents a day.... DO IT.
(in the face of no destructive data...which is the situation for B12-- our own government has a website suggesting B12 for all people over 50. Do you think that will change too? Perhaps).
