What our customers have to say
My diet is largely plant based, so I have vitamin B12 deficiency pretty often. So far, I always found out because I had symptoms. So much better to just be able to test regularly at a good price and take supplements before I ever get a deficiency!
I´m vegan and I know that I need to check my vitamin B12 levels regularly, but having to go see a doctor is such a hastle and you always have to also pay for the consult. Being able to do this from home by myself is so much easier!
