I was diagnosed with a significant B12 deficiency a few years ago, likely due to H. Pylori and many years as a vegetarian. I tried methyl b12, but couldn't tolerate that form (it made me so drowsy I would have to immediately sleep for hours). I read that the hydroxy form was also a good option, so I've been taking this ever since. It took awhile for my body to feel better, but I believe these played a huge role! I take one, sublingually, each night before bed. They're small, taste fine, and only take from 15-30 minutes to dissolve.

Thanks for your feedback!

Prescribed by our naturopath for 9 year old son who suffers from chronic illness and methylation issues. He takes this along with 5-MTHF by Thorne. Both seem to be helping. I really like the fact that it is a tiny chewable lozenge without a horrible taste. Makes it easier for children!

Thanks for your feedback!

Decreases nitric oxide and detoxifies cyanide. However, it decreases nitric oxide too much for me, creating vasoconstriction and causing a headache

Thanks for your feedback!

Have noticed a difference since taking these although my body seems to need methyl-B12 more. Was really hard to find a reasonably priced brand of just hydroxy-B12, but these tick the box. Very happy - I even bought a couple of extra ones for my elderly father who seems to have more energy since taking them even though he would deny this as he "doesn't believe in supplements" haha. Recommended. Thanks again iHerb!

I find this to be the best B12. I was not aware there were different kinds. After having my DNA done, I was informed (because I ran my DNA through nutrahacker) that I needed the Hydroxy B12 based on my genes. Wow! What a difference!

Thanks for your feedback!

It is great

I use this form because of genetic methylation issues with other forms.

Thanks for your feedback!

Effective and tasty

Effective sublingual tasty formula, providing top absorption. Very efficient form of B12. As a bonus does not contain mannitol which annoys people with IBS.

Thanks for your feedback!

The best B12!

I was so sad when I saw that my previous provider was out of stock with this supplement. Happily, found it on iHerb and will continue to use this brand as it proved to be the best one for my MTHFR mutation.

Thanks for your feedback!
