well goggle this : vitamin b12 effects fatigue jama new england journal of medicine - read those results for a bit .....
pretty credible sources id say huh? since after all it is the QUALITY of the studies not the quantity.... *L*
and check this out re appetite:
http://www.patrickholford.com/conten...d_Content=1461
(cites effects on appetite in elderly dementia patients and lack of b-12 and b6 and the direct correlation )- info here also taken from JAMA and NEJOM ...again ...credible sources right?
Now please do not come back with - there are no studies on healthy males blah blah blah - of course not , much like broken fingernails .....these studies arent pursued ...there are sick people that need treatment. ....so why bother to study the benefits of b12 in the above circumstance? The evidence in the above is more than ample to suggest the possibility of b12's fatigue fighting and appetite stimulating properties . That combined with real world comments on the fact it does those things ,comments by people who have nothing to gain by saying so .....well lets just say it SHOULD quiet the skeptic ...who loses sight of the topic and are more concerned with saving face at times.....
Oh and btw before you ask people to cite a study to support their real world experience...maybe you should take 2 mins and google yourself? They have no responsibility to prove their experience is valid - to you or anyone else..
JMO ......
