Product Overview


  • Dietary Supplement
  • Biologically Active Form of B12
  • Quick Dissolve
  • Suitable for Vegetarians
  • Purity & Potency Guaranteed

Methylcobalamin is active immediately upon absorption, while other forms (e.g., cyanocobalamin) must be converted to methylcobalamin in a two-step process. Methylcobalamin demonstrates exceptional activity in areas where other forms are simply not active. B12 supplementation is recommended for vegetarians and those suffering from B12 deficiency.

Manufactured by Natural Factors to ensure safety and potency in accordance with Good Manufacturing Practices (GMP) of the FDA and Health Canada.

For people with B12 deficiencies it is popular to have injectable vitamin B12; however, research supports that oral administration of an appropriate dosage has been shown to produce as good of results as injectable preparations in treating vitamin B12 deficiency.

In people with low levels of B12, supplementation is very effective in improving energy levels and restoring mental function. B12 supplementation is recommended for vegetarians and those suffering from B12 deficiency.

Check with your doctor or health professional on what is the best form and potency for you.

Methyl cobalamin

I've been taking this for a while. And it has helped stretch out my need for injections of b12 from weekly to about monthly. But if my stress levels get to high I can chew heaps of these and still need an injection. I also give them to my 4yo daughter.

I have tried so many different supplements of B12 and this one is the best. It dissolves instantly and tastes good and makes my body feel good.

Despite eating healthy and taking vitamin supplements for years, I've had B12-levels on the low side. I bought these on a whim, hoping for a boost, and after 1,5 months, my B12-levels had risen from 200-ish to above 1000! My doctor was thrilled! The pills are small, dissolve quickly in your mouth, and doesn't really have any flavour. It does turn your mouth, teeth and tongue very red, so it's not a good idea to take one in public.
