Boy, I so think that "over 50" as the medical community insists, is not helpful to people who are much younger and suffering the effects of malabsorption.

I talk to so many people in stressful jobs, and tell them to look at their fingernails for ridges... many in stressful jobs find that they have ridges... they say they are going to get Methylcobalamin lozenges... but I never know how it goes because they tend to be techs and support people in different businesses, so I seldom talk to the same person twice.

Because I have found, in my experience, that stress depletes B12 -- or maybe what it does is interfers particularly badly with absorption -- I think that many people well below the age of 50 need supplementation...

and, if their symptoms are severe, I would recommend that they try something more like a 5mg Methylcobalamin lozenge a few times a day... keeping notes to see what happens over a month...
