    [I'M SO SORRY, I CLUMSILY PUT THIS INTO THE WRONG THREAD! PERHAPS AN ADMIN COULD MOVE IT TO THE B12 CONVERSATION FOR ME?]

    Interesting article from Wikipedia. I looked it up to see if some areas of the skin are more permeable than others, partly expecting to see nasal tissues and the skin inside the anus mentioned. It seems it is true, though perhaps not in the way I thought! Scrotal application, guys...? :rofl:

    They also mention a chemical compound that enhances absorption:

    @alicec great to get your input on this topic. I think the importance of B12 for most visitors to this site can't be overstated and it looks like we're finally getting some discussion happening based on scientific literature which always helps.

    To clarify, is that a typo where you say "(I think there is a patent so possibly that can be found)" and you intended to say it can't be found? In the interests of his own business and the health of visitors to this forum wouldn't Dr Russell-Jones do well to make this literature available so we can have some confidence in this transdermal b12 delivery system since many of us may be relying on it as the cornerstone of our treatment protocol?

    Regards

    It seems to me that Dr Russell-Jones transdermal B12 probably does give a strong and lasting b12 dosage (as supported by the experiences of many people in this forum) but in the interests of economy and this whole dalton absorption issue I'm going to try my first nasal b12 system. Especially since it seems that the best way to treat a b12 deficiency when using passive diffusion methods (lacking intrinsic factor?) is to take small doses frequently through the day rather than mega doses once a day (something I used to do myself)
    Any recommendations on the best b12 nasal spray (preferably best value but also good quality)?

    Regards

    Myself I use pure B12 methylcobalamin powder, and snort a small amount (about 5 mg) into the nose using a drinking straw. You can buy B12 powder on ebay (though make sure it is pure, because if it contains say a citric acid preservative it will sting like hell if you snort that; anything acid hurts like hell if snorted into the nose).

    You have to store B12 methylcobalamin in the dark, because light causes it to break down. And when you open the jar of methylcobalamin, it's best done in subdued lighting. Other forms of B12 do not have this problem of photosensitivity.

    No I meant what I said. If someone cared to search for it I imagine they could find the patent behind B12 oils.

    Note this patent would not be the same thing as some in the list linked by @Hip where substances are attached to B12 and the B12-IF absorption system is used to get oral uptake of the linked substance.

    Lol the lengths we go to in this quest for health. I wonder what my neighbours will think if I add snorting B12 to my protocol. They're already wondering what the hell's wrong with me every morning when I doll out my numerous vitamins. :)

    Ps - I just followed your signature block link re: anxiety only to find that I'd already read and acted on it previously! I used the N Acetyl Glucosamine back about 1.5 years ago with high hopes. Didn't notice much of an effect but rarely are these things for nought. Sure enough, whilst recently revisiting some blood type diet reading material I found something that explained that dietary lectins are effectively treated by NAG! My fairly strict adherence to the blood type diet for the last 6 years may explain the limited gains I experienced on NAG that I otherwise would have got if I followed a 'normal' diet containing wheat and dairy... Am fully on board with the notion of brain inflammation as a causative agent in the bottom up dominant mode of thinking that I suspect accompanies GAD cases. Without enough circulation going to the outer regions of the brain due to the inflammation the top down executive processes arent getting enough opportunity to work. Where the DLPFC is the most relevant structure I believe...
    Your insights regarding sinus congestion and anxiety are _extremely_ interesting. I'm putting it together with what I've learnt in TCM that people with weak 'Spleen Qi' (who also tend towards having this congestion of the upper respiratory system) and it supports the notion that the anxiety may be a by product of the sinusitis which in turn is the result of inflammation...

    All forms of B12 are light sensitive. Some formulations also require refrigeration.

    It is true that methylcobalmin is the least shelf-stable of the forms, so being extra careful with that form is a good idea. It can end up being an awful waste of money otherwise.

    I was under the impression that you only have to worry about methylcobalamin when it comes to avoiding exposure to light, but you're right, I found this 2013 paper which says that all forms of B12 undergo photodegradation (aka: photodissociation, photolysis) in aqueous solution.

    Interestingly though, the study found that methylcobalamin and adenosylcobalamin in water were converted into hydroxocobalamin within seconds by the action of UVA light. They found hydroxocobalamin was the most stable form under UVA light.

    So you don't actually lose any B12, it just changes into hydroxocobalamin (although hydroxocobalamin may eventually degrade under the effects of light as well, and I am not sure what hydroxocobalamin degrades into.

    They point out that other studies have found methylcobalamin to be around 3 times more sensitive to UVA radiation than adenosylcobalamin. I also found this study which says: "the photochemistry of methylcobalamin is found to depend strongly on excitation wavelength, while the photochemistry of adenosylcobalamin is essentially wavelength independent over the range studied."



    The 2013 study also says:


    I believe B12 is more stable in dry form compared to when dissolved in water, although I can't find a reference for that at the moment.
