New B12 breath test coming out soon

It looks like it's on the way soon. I put all the athletes I train, whatever their diet onto B12. I think once a simple test like this comes out the amount of B12 deficiency in the general population will be much larger than expected. It will be awesome to be able to show people they are low & it will be so easy to check most people could check it out if they have a concern!
