The prescription I had that was so much help to me, such unexpected help, was for a shot a day.
That would be equal to about 6 of the 5mg Methylcobalamin lozenges a day... and sometimes I had and have two shots a day, which would be 12 of the 5mg lozenges a day...
I forget, are there 60 in a bottle?
If so, then a bottle would only last 5 days, which would be vastly more costly than Cyanacobalamin shots. (even including the cost of the needles.)
basically, I'm glad I learned about Milk Thistle.
