B12 gives me more energy, stamina, and improves my mood, as well as keeps my memory sharp.

Pleasant Surprise

Posted by Reviewer1235529 on Jul 30, 2008

Been taking this on a tip from a patient and it DOES lower your cholesterol! Mine went from 210 to 165! Take with B-2.

B12 not irritating

Posted by Reviewer2863009 on Apr 07, 2009

I like this B12 because I do not get a heating, inflamation causing reaction from it, which I get from other B12's. I take 1/2 a pill twice a day.

Natural Factors B12 1000mcg

Posted by Reviewer1143531 on Oct 20, 2011

I take this daily in addition to getting one B12 shot weekly. I have a condition where I do not absorb B12. I find that by taking this product along with the shot, I do just fine. If I don't take the pill form, then I can certainly tell the difference.
