I have been taking Dr Martins B12 for several years now. It keeps my B12 levels where they should be and therefore contributing to my good health. No known side effects, just an orange tongue.

This product gets me what I require, and very efficiently.

I have tried different Vitamin B12 before but nothing beats Dr. Martins B12 I noticed a big difference

I notice my energy level decreases when I run out of B12… I feel great taking it

I have been taking for maybe 2 weeks now and perhaps notice a slight improvement in my energy. I feel I need more time using it to give a proper review. One thing I don’t care for is the orange colour! It leaves my tongue and lips orange, since it sits under your tongue until fully dissolved which takes some time. Otherwise no complaints, just want to see how I feel in another month.
