Excellent Methyl B12

Posted by iHerb Customer on Aug 13, 2017 | Verified Purchase

This methylcobalamin is my preferred brand, even though it is a bit more expensive. Tiny tablet, very few ingredients added, easy to take. Virtually no flavor. I would recommend this to anyone who prefers no added sugars, sweeteners, or flavors in a supplement.

Thanks for your feedback!

Good product
