Thanks. Yeah, the Nutreval looks like a good test and eventually I’ll get it done, but it’s do darn expensive. I need to find a doctor That’ll do it with insurance...
How do y’all find products that have such small amounts of these things? For example, Methyl B12 always comes in 1mg lozenges; do you cut that up in ultra tiny pieces or have I not found the right low dose product yet?
If you are not tolerating tiny amounts, it's likely you have some sort of toxicity problem, like mold or heavy metals. A doctor could help you work out an appropriate protocol.
There is a B12 oil absorbed through skin you might look into in the short term, but you will need to take the other nutrients, too.
