Product Overview


  • Nervous System Health
  • Essential for Energy Production
  • Methylcobalamin
  • A Dietary Supplement
  • Vegetarian - Vegan
  • Vitamins
  • Family Owned Since 1968
  • GMP Quality Assured

Vitamin B-12 is necessary for the production of energy from fats and proteins and is well known for its critical role in DNA synthesis, as well as in homocysteine metabolism. Methylcobalamin is the co-enzyme form of Vitamin B-12 that has been found to be especially critical in the maintenance of a healthy nervous system. Dietary sources are almost exclusively of animal origin (meat and dairy) and supplementation with B-12 may be especially important for strict vegetarians. Now Methyl B-12 is vegetarian/vegan (non-animal derived).

Severe irritability and causes anger, too strong

Posted by iHerb Customer on Nov 29, 2017 | Verified Purchase

this dosage is too strong, please buy the lower dosage and try out. i took one pill of this, and withing minutes, my mood changed drastically. i became sullen, angry and badly irritable. i got irritated over petty things, i'm usually calm and laid back. i stopped for a few days and the symptoms die out over time. i took it again after the break and the anger and irritability came back. i had to alight from the bus to prevent from bursting out in anger, as i was greatly irritated. it was over something so minor and petty, typical passengers inconsideration which i'm used to ignoring on daily commute. i'm usually calm and not bothered. this pill is too drastic. i was so agitated even when i'm at home surfing the net, i got angry because of a typo i made. PLEASE DO NOT TAKE THIS LIGHTLY I COULD HAVE SCREAMED AT SOMEONE, THAT'S HOW BAD THE ANGER WAS. even cutting each pill in half, has the anger and irritability symptoms, albeit slightly lesser. which only means that this can only be taken in very low low low dosage. I have since stopped taking this for weeks. and i'm no longer irritable or angry.

Thanks for your feedback!

I am VitB deficient and these are my fav B12 vitamins I've tried and believe me I've tried them all! For me they work best before food - and i then i wait 20 minutes to eat.

Thanks for your feedback!

too strong!

I bought one of this for myself and one for my mum and sister overseas. Unfortunately it's too effective, my sister started to get eye pains and I kept waking up at night. I realized this was the problem after a bloodtest, normal range for B12 is between 110 to 600, my reading was >1470! I was taking it daily for about 3 weeks. I would recommend taking this once a month and after a few months even less frequent, or get one that's only 1000. Just get yourself tested after a while to see if you've gone over the limit.

Thanks for your feedback!

I was looking for a high dosage B12 to take for my ALS - (called MND in Australia). Take 2 a day to suit my needs. Didn't want to chew a handful of B12 a couple of times a day at lower dosage.
