This works, and it's much easier than shots!

Posted by iHerb Customer on Nov 01, 2007 | Verified Purchase

When I finally convinced my doctor to check my B12 level, and it was practically non-existent, she wanted me to come in for the B12 shots. I told her I wanted to try the sublingual B12 first. She just shrugged. But two months later, the blood test was repeated, and my B12 level was in the mid-normal range. Much improved! And without those painful shots. I highly recommend this product.

Thanks for your feedback!

Excellent product

Source Naturals B12 sublingual 2000mcg do a great job keeping my B12 blood levels- and my energy- at optimum levels. I have pernicious anemia and depend on daily high-dose B12-supplements for the maintenance of my health. I have tried countless other brands with more or less success. These are by far the best and I wouldn't use any other brand any more!

Thanks for your feedback!

Not the good B12

Posted by PeterSmithUK on Apr 05, 2012 | Verified Purchase

This is cyanocobalamin not methylcobalamin. I bought it by mistake. The cyanocobalamin COSTS the body methyl groups which controle homocysteine and reduce inflamation. We want methyl groups, so only ever take the good natural form of B12 : methylcobalamin.

Thanks for your feedback!

Good product

What differentiates this product, is that it has 2000 mcg as opposed to the standard 1,000 mcg B-12. Even if the body dispels the extra, it's there if the body requires it. Good value overall.

Thanks for your feedback!
