Toothpaste for B12 deficiency

For those of you who are concerned about your B12 levels: have you heard of B12-fortified toothpaste? I literally just found out that this was a thing and I thought it might be something that some other vegans might be interested in.

Here is some research showing that it increases B12 levels:

A double-blind, randomized, placebo-controlled study of the elderly: [https://pubmed.ncbi.nlm.nih.gov/30680547/](https://pubmed.ncbi.nlm.nih.gov/30680547/)

Another study, also double-blind, randomized, and placebo controlled, done on vegans: [https://pubmed.ncbi.nlm.nih.gov/28052884/](https://pubmed.ncbi.nlm.nih.gov/28052884/)

And here are links to a few of these products:

For the record, I have not personally tried this product and cannot vouch for it at all. I just wanted everyone out there to know that this does exist and you should do your own research to decide if it's right for you.
