Pastachef:
A vitamin B-12 deficiency can lead to Pernicious Anemia, premature destruction of red blood cells. Symptoms can include fatigue and lethargy. The deficiency occurs commonly among strict vegetarians and alcoholics. Still, there are some people whose body simply absorbs/stores insufficient amounts - if at all.
Among the alcoholics, alcohol itself has destroyed the digestive tract's ability to absorb B-12 and produce intrinsic factor, a gastric substance that aids in B-12 absorption.
So the the problem stems either from lack of intake or malabsorption of B-12. It APPEARS that you may have/have had pernicious anemia for one of several reasons.
Mention all of this to your personal physician and request a hematocrit type blood test. It will test for anemia.
Ascertain that your supplement does not contain ephedra, fo-ti or ma huang. Those three substances are stimulants. Many supplements contain them and therefore people taking them are misled into thinking that it's the vitamin/mineral that did the trick when in reality it's the stimulant that effected the "positive" change.
