Possibly you might better off with a filler powder which dissolves in water, rather than something like rice powder which does not dissolve, and so will remain in the mouth.
You don't necessarily have to mix you B12 powder with a filler though: I used to use B12 powder, and would measure out 10 mg doses using a digital scales, a model with an accuracy of 1 mg. These cost about $10. Then I would apply that 10 mg of B12 powder to my oral mucous membranes (insides of cheeks, gums and under the tongue).
Not much B12 is absorbed sublingually though, so if you don't experience benefits, then B12 injections or
B12 transdermal oils (which provide similar systemic doses as injections) can be considered. B12 oils are both cheap and much more convenient than injections.
I'd rather not use water because the one gram of powder cost $250 and should last me a year at a dose of of 3mg/day (maybe I should be doing 10mg, anyhoo). And if I mix with water, it doubt it would last year. I'm sure it won't. I compound something else in distilled water, and it molds after several weeks if I don't go through it. I haven't opened the container with the 1 gram of hydroxyC powder, but I'm guessing there is less than 1/4 teaspoon in there, and that's 1,000 - 1 mg doses, or 100 - 10mg doses - which would be $250 every three months. Too expensive. Maybe I'll try 5mg.
Where did you source your B12 and is it hydroxyC or another form? I had my pharmacy order it, so it is pharma grade from PCCA.
I guess I was thinking that the rice won't dissolve, but if I swish for a minute or so I can then spit it out. LOL
I'm wondering if I'm doing my math wrong? I have a 1 gram scale that goes to 0.000 grams, but all the comments state you have to have a very expensive to scale to be accurate at milligrams. I was trying to calculate tonight and 1,000 mg is 0.001 on a gram scale (am I off by a decimal point?). So, mine won't even go down to 100mg, let alone 10mg.(Mine was $15 or $20 online) I thought I tried to find a milligram scale, but they were extremely expensive. I'll look again.
I have a methylmalonic acid problem (and pernicius anemia) and need plenty of B12, spent a ton of time researching the last 4-5 months. It seems the older information all stated that B12 needed to be injected, but there are quite a few newer studies stating that sublingual is just as good. Indeed, many people with MMA in other countries cannot get injectable B12 and are doing well - even those with life threatening MMA. I
was on hydroxC injections, but I'm trying to get pure ingredients w/o fillers, preservatives, etc as much as I can. And my doc doesn't see the need for more than 1mg/day injectable since it controls my mma, (but not my symptoms, ughh).
I haven't heard of transdermal B12. That is very intriguing. I've been making some of my own transdermals and adding DMSO to some of them making them even more effective. I wasn't aware that B12 was small enough to get in transdermally. I'm surprised that wasn't mentioned in the MMA groups. This would be awesome for children with MMA who are on injectable!
My other option is to purchase a 1 or 10 milligram weight and test my scale. Maybe I could just take it to a jewelry store and they would have something that weighs one or 10 milligrams.
Nonetheless, I need to dilute that tiny bit of 1 gram of hydroxycobalamine. Yippee. Maybe lactose and just use half the gram at a time. I'm worried the lactose would spoil, but it hasn't in my other compounded med, but it might contain a preservative. IDK.
Thanks for your thoughts and help on this
