Posted by Reviewer1027069 on Nov 20, 2008

I bought this for my husband who was complaining of having no energy. This has made him feel more energetic and to think clearer.

I am taking as a preventive for age relative decline. I also have Hypothyroidism, known to interfer with B-12 absorbtion. My B-12 levels are normal, and the Methylcobalamin form is superior to the Cobalamin. Sublingual of course. Will continue with this one!

Definitely not the best tasting thing on earth but it dissolves pretty quickly so it isn't too bad. I wish it would have come in some kind of flavor. It feels like if you are putting a piece of chalk in your mouth but with that said, I would probaby order again.

Works well

This really does make a difference, wish I had found it sooner. I made a mistake and bought the other type of B12 also sublingual tablets, and didn't do well with it.

I like the way it desolves under the tonge. It gets into my system very easily and the price was very reasonable. So far, I am satisfied.

So far, so good!

I tested low in B12 so sublingual tablets were recommended by my doctor. I will be retested in 2 months & I will know then if this brand is working or not. Everything I read about Natural Factors was positive & it appears to be a great natural product. The price was good & the service at Iherb can't be beat. I may be back to give it a five star rating, if Iherb will let me post again in 2 mos.

I do marathons and this helps a lot especially when you have to work and do daily chores and still have energy to keep going.
