@zzz -okay, get ready...I was trying to implement Anthony Williams protocol. Just a little and I KNOW that people on here hate this guy.
I am blissfully unaware of his existence, so I am addressing your concerns without regard to who he is.
I do know that my B12 is low. B12 and magnesium. I put the magnesium on again today and it burns my body.
Getting enough magnesium in a well-absorbed form that is easily tolerated can be quite a challenge. Almost all topical magnesium products are made with magnesium chloride, and it is the chloride that causes the burning sensation. (Think hydrochloric acid.) Fortunately, magnesium sulfate is available in a cream, specifically
Kirkman Magnesium Sulfate Cream. I have been using this for a couple of years, and I experience no burning whatsoever from it. Its active ingredient is the same as in Epsom salts, which also don't burn, at least when applied externally.
Epsom salt baths are also an excellent way of getting substantial amounts of magnesium into the body. I noticed that you mentioned that you take them; either taking them more frequently or gradually increasing the amount of Epsom salts per bath, or both, may give you greater benefit from this method. A simple way of knowing when you've overdone it with magnesium is if you become excessively tired or hung over after the treatments. Feeling nicely relaxed is fine.
Anyway, the woman I am working with who is most kind and got better from his protocol says it must be a methyl B12. Does it matter? Why does it even matter?
Methyl B12 is widely used because it delivers B12 to your body directly in the form that your body needs it. But for people with issues with overmethylation, hydroxy B12 is a much safer form of B12 to consume, and you can still get all the active B12 that you need.
I have hydroxy B12 from 3 years ago. Is that too long ago? Meaning, did it go bad?
Hydroxy B12 from 3 years ago should be fine. Drug and supplement companies tend to be very conservative about expiration dates. Even though most drugs last well beyond their expiration date, there is no motivation for the manufacturer to test this and verify this. And if people throw out drugs long before they need to and replace them with new drugs, this is to the financial benefit of the manufacturer. The NPR article
That Drug Expiration Date May Be More Myth Than Fact contains an excellent summary of the many tests that have been done showing that drugs often last many years past their expiration date - very frequently a decade or more, and sometimes many decades. The one exception you have to be especially careful about is doxycycline - it turns toxic after its expiration date. To a lesser extent, this is true of other tetracycline antibiotics as well.
Taking a large dose of b12 could deplete your folate from your diet since they are paired together metabolically. So one needs the other to work properly. Certainly folate depletion can give you similar symptoms to b12 depletion ...some of what you describe could be this. Although everyone is different and has different needs etc.
This is very true, especially the part about everyone being different and having different needs. I was someone for whom methyl B12 turned my illness around quite dramatically 16 years ago; I didn't even try folate supplementation until a number of years later. When I did, I found a rather modest positive side effect, though qualitatively different from what I experienced with B12. One of the most frustrating aspects about this illness is that there is no "one size fits all" for
any treatment, and people often have to experiment a lot to see what works best for them.
