I had severe B12 deficiency for many years and no prescription medication worked (in Norway it is normal to give B12 in the form of cyanocobalamin). I was advised to try methylcobalamin in higher dose than you can buy in Norway. I ordered my first box on iherb, and now I have taken this type for three years. Results off bloodwork are better than ever(I'm stable on 700-800 nmol/L). Recommend this highly! Tastes good too :) You can't overdose B vitamins since they are water soluble , the body absorbs what it needs and the excess is excreted through the urine. I recommend that you take a good B complex when you start supplementing with B12 and / or folate . This because supplementing only with B12 / folate may camouflage the lack of other B vitamins. When you have low values / lack of B12 / Folate, you will also likely have low levels of other B vitamins. Visit my iherb page to find a recommendation for a good B complex and several other recommendations and reviews. Was this review helpfull to you? Pleace press "Yes" below :) NORSK: Jeg har lidt av alvorlig B12 mangel i en årrekke og behandling med reseptbelagte tilskudd/injeksjoner har ikke virket/hatt minimal effekt. Jeg begynte og lese meg opp på dette med vitaminer og mineraler og ble gjort oppmerksom på at man kun får kjøpt B12 i form av cyanokobalamin (syntetisk B12/kjemisk fremstilt) i Norge, unntaket er muligheten for injeksjon i form av hydroksokobalamin som har noe bedre opptak. Jeg ble anbefalt av en privat lege med god kompetanse på feltet å forsøke tilskudd i form av høydose methylcobalamin. Methylcobalamin er den naturlige formen for B12 og den har høy biotilgjengelighet/godt opptak. Jeg har nå benyttet denne formen i 3 år og har stabile B12 verdier på 700-800 nmol/L. B vitaminer kan ikke overdoseres ettersom de er vannløselige, kroppen tar opp det den trenger og overskuddet skilles ut gjennom urinen. Jeg anbefaler at du tar et godt B kompleks i "bunn" når du begynner med tilskudd av B12 og/eller folat. Dette ettersom å supplere kun men B12/folat vil kunne kamuflere mangel av andre B vitaminer. Når du har lave verdier/mangel på B12/Folat vil du også sannsynligvis ha lave verdier av andre B vitaminer.

A necessity to take for at least a week when Bell's Palsey or Shingles first occur. The only substance that repairs nerve covering. I keep some handy. As good as a hypodermic of B12, at ten cents a dose.

One of these per day, dissolved under the tongue, keeps my blood level of B12 above normal range.

My mother in law shared with me how she was able to stop taking an expensive anti-depressant medication after taking B-12 along with D-3. So, I've begun taking each as well. I'm not sure what all factors in, as I have also taken a GABA product. All I know is this winter has been much better for me than the past few in regard to seasonal depression.

Jarrow B12 is OK, my child likes it. One lozenge per day and after 2 months his B12 level was over 1000. In the beginning it was 170! Cyanocobolamin injections did not work but methyl B12 did work very quickly!

I'm a vegetarian, almost vegan. A blood test done after using the product showed a good level of vitamin B 12.

I tried this to help a Morton's neuroma in my foot, and also bursitus. I also had numb patches in my feet for years I thought was nerve damage from an injury. After a week the pain in my foot was already less and the feeling came back in the numb patches after years of them being numb. Turns out numb patches can be a symptom of B deficiency.

i got this because i had nerve damage done due to my wisdom teeth coming out and the left side of my tongue was numb, for over 8 months. my doctor suggested b12 (which i was taking) but it was not helping enough. its now been less then a month of taking this and i see more results in the curing the numbness of my tongue then in the 6 months of taking normal b12. as of the moment of writing this, my tongue is almost completely healed. i can feel it, but there is still a tiny bit of numbness left, about 95% normal (which at this rate, will be gone within 2 weeks) i am so happy with this product that i highly recommend it to anyone.
