I started taking Vitamin B12 supplement 8 days ago as intramuscular injections of 1000ug of
Hydroxocobalamin injected into the thigh with 2ml syringe and 25Gx25mm needle. B12 deficiency is not a joke,
it can manifest itself in a lot of very very serious conditions, CHECK THIS OUT. If you do not know your B12 levels, go take a test and or see if the symptoms match and if you are low or doubting then supplement. Best forms of B12 to take are hydroxocobalamin and methylcobalamin. Cyanocobalamin breaks into cobalamin and cyanide in the liver so do not be taking that crap.
Self medicating is much more cheaper than going to the doctor and usually the doctors do not even know about B12 deficiency let alone wanting to prescribe the injections or treat you. In a lot of countries you can get B12 as hydroxo or methylcobalamin in ampules over the counter and of course from the internet if you live in a country that does not permit you treating yourself. 1 2ml ampule of 1000ug hydroxocobalamin, 2ml syringe and 25Gx25mm needle costs about 1-2e depending how much is ordered at once.
YouTube has videos on how to self inject B12 so if you are thinking of fixing things then check them out
Sublingual and oral supplementation might work but IM definitely works.
More info (personally have not yet read the book, only flew accross the pages to check the treatment info but this books seems to cover it very well) in
Could it be B12 for those wanting to know more.
Will probably add more or make this post more well put later as it already is late but this is so damn important that this lays here as is for now.
EDIT: subcutaneous injections are go over IM since IM goes too fast out through urea and also 50% of it does not absorb and SC absorbs more slowly and does not "spike" I have understood since posting this so if you have B12 issues check the book out and search engine this
