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.

This was the first time I ordered this type of product. They do not melt easily. In fact, it takes about a half hour. However, this may not be unusual.

Can't tell any difference whatsoever.

Ordered on a Friday afternoon and shipment arrived on Monday with standard shipping to Sydney, Australia. They do take a long time to dissolve but they taste alright and the texture is fine. I haven't tried any other type to compare it with.

B-12 (seems to be all brands I've tried) supplied me with warmer extremities (anemia symptom), and provided more energy. The downside when I add these to my regimen, B-12 makes me want to eat, eat, eat non-stop. Until I can figure how to supplement these, without that side affect, these have been put on the back burner. But still a nice supplement.

I like to take half a tablet at a time. Some bottles come with tablets that are easy to break in half in my hands. The other are impossible. It indicates to me that the ones that are easy to break are clean and fresh. The others are stale at the least.

I bought these under the impression that they were quick dissolving sublingual tablets. They're not,you have to chew them. They taste good,but I will not be ordering them again because I feel like sublingual tablets are more effective.

Not sure about the effectiveness... but I am taking them cause I'm vegan. It tastes great, light on the stomach, good dosage and affordable.

I didn't like the flavour and did not feel very different after taking this.

I started giving my child B12 supplements after she developed an autoimmune condition, as apparently many people with autoimmunity suffer from B12 deficiency. I don't know if it's helping, but it's not hurting, these are affordable, and she likes the taste. Will keep buying. Ooh, also worth noting: some brands of B12 don't resist moisture very well, even with the silica packs in the bottles. Jarrow is excellent (Doctor's Best was the worst, and were practically melting by the time we got to the end of the bottle).
