Dislike the mannitol and sorbitol - going to try California Xtracts or Jarrow Formulas. Note: high doses of B12 may deplete iodine, iron, zinc, manganese

1) Pure Advantage methyl-B12 spray - ineffective (I wonder about the sorbate preservative in it); 2) InterPlexus Inc NutriSorb liquid hydroxycobalamin - effective but still needs to be 'converted' to active form - I found the one drop dose suggested on label isn't enough; 3) Solgar cyanocobalamin 1mg sublingual - dissolves too fast and not as effective as active methyl-B12; 4) Natural Factors methyl-B12 1mg sublingual - dissolves too fast under tongue but found it better inbetween gum/lip where it will sit and dissolve more slowly. Iodine/B12 are synergists - suggest adding/increasing either one if taking more of the other, especially long term. Same is true of other nutrients such as manganese and zinc (both need cobalt, high cobalt may deplete them) - could be why some people note headaches after taking high doses of B12 (both high and low manganese can cause migraine-headaches). High doses of B12 will also deplete iron - they are antagonists. If this review was helpful to you, please click YES below - thank you.

The best Methylcobalamin I tried till now with a good taste!
Posted by Reviewer1491632 on Feb 22, 2012
In the past I tried a lot of high dose (5 mg) sublingual Methylcobalamin supplements from different brands. But I had a couple of problems with most brands. The 5 mg Methylcobalamin pills from Now Foods and Superior Source (microlingual) are not good protected to degradation. Some pills from this brands are broken in the bottle or worse there's sometimes not much left from some pills, only powder! The taste from some Methylcobalamin supplements is also mostly to sweet, like you are eating cheap and to sweet candy. But the sublingual methylcobalamin pills from source naturals have a more neutral fresh taste (a bit more like toothpaste) and the pills don't degradate at all! No broken pills and no powder at all, only complete pills. The only negative point of the methylcobalamin pills from source naturals is the additive content, that could be less.

My doctor said I was deficient in B12. I've taken this product for two weeks. had blood test, and was no longer deficient!

Part of my porphyria protocol, the best B12 I can get to help with the peripheral neuropathy associated with porphyria and restless leg syndrome
No injections for me

My B-12 level has dropped to around 200 and the MD wanted to start B-12 injections. I decided I wanted to use oral B-12 and my level within months was above normal. Much easier than injections. As a side point I put a diabetic cat on B-12 10mg once a day for her neuropathy that the Vet said would never go away. Within months her neuropathy was gone and she was able to walk normally again. This was 5 years ago and she hasn't had to take B-12 in 4 years and none of the symptoms have returned.
Tasty and easy B12

Melts easily under your tongue and contains the best form of B12 for hypothyroid people, methylcobalamin.

Very happy with all purchases and especially with the speed of the delivery. Several of the MethylCobalamin were broken - split in half sideways as one would slice a bun.

I just had a b12 test and my b12 is WAY too high. It's a sign this stuff works and that I can cut it back to only two pills per week.

We read about how vitamin B-12 can help with dementia and early alzheimers. My grandma began taking 5mg 3 times a day and it is amazing to her progress. She was very forgetful and repeating thing over and over again. She has been on the B-12 for about 2 months now and we are already seeing an improvment.
Great for vegans

Gives me lots of energy when I work out. Not sure if I need to cycle it, but I use it 5 days on and 2 days off a week.
