I've had a read through some of Rich and Freddd's various posts. I have to say, it's overwhelming, and raises a lot of questions and a bit of skepticism. One question would be, why is there such a void when if comes to clinical studies in this area? That said, I have always tested low for B12 in blood tests, and have had some positive experiences with sub-lingual B12 drops. After using sub-lingual drops of B12 daily for 12 months, I had another test and which was still low. I've more recently been jabbing myself once a week in the leg with intra-muscular shots of B12. I'm interested in trying other forms of B12, as I am cautiously curious if there is something to it. Does anyone have a simple protocol and set of supplements which wont break the bank? I'm looking to replace the Sub lingual B12 drops, in favor of one or two other supplements. Help appriciated, thank you.
