Product Overview


  • Casein & Gluten Free
  • Dietary Supplement
  • Scoop Inside

Methylcobalamin is the most active form of vitamin B-12, and it is extremely important in folate chemistry and methylation processes. There are other forms of vitamin B-12; however, only methylcobalamin can be utilized in the central nervous system.

Kirkman offers methylcobalamin in a concentrated powder that tastes good and dissolves quickly under the tongue or mixed in drinks.

Cyanocobalamin is the most common form of vitamin B-12 and is the form used in most vitamin supplements. The reason for cyanocobalamin's presence in multivitamin supplements is its superb long-term stability and its relatively low cost. Cyanocobalamin is converted to methylcobalamin in the liver, but not in amounts that are considered significant. For this reason, many physicians are using very high doses of methylcobalamin. It is usually given subcutaneously, though some physicians are trying other routes of administration including oral administration.

Suggested Use

Place 1/2 to 1 level scoop of powder under the tongue and allow the powder to dissolve or dissolve in a liquid and drink immediately (do not store unused liquid).

Other Ingredients

Mannitol, sorbitol, sodium starch glycolate, natural tropical punch flavor, citric acid, silicon dioxide, methylcobalamin.

Free Of: Sugar, soy, wheat, casein, gluten, egg, preservatives, yeast, gelatin, artificial flavorings or colorings, peanuts, tree nuts or fish.


Store in a cool dry place and tightly capped.

Excellent product

Posted by hiqfish on Feb 23, 2014

Kirkman Labs Methylcobolamin powder is the best B12 product I bought up to now. Methylcobolamin is better absorable than Cyanocobolamin and can be taken in higher doses without any side effects. Makes Your mind clear and gives You much more energy. Half a scoop is mostly sufficent as a daily dose and even less than that is still very effective. I give a 100% recommendation for this product! It is very useful during pregnancy. My wife profitted a lot of this B12 product and had almost no problems during her pregnancy. Also her slightly depressive mood desappeared after a few days and remained much more stable and she had a much higher energy level.

Versatile & effective.

I've tried other methyl B12 sublinguals, and this is by the far the easiest product. I suspect it is exactly the same source product as Source Naturals methyl-b12, just not pressed into tablets. The powder dissolves in seconds compared to minutes with the stamped tablets. But however you take this master nutrient, be sure it features in your regime.

Economical and Tasty!

Posted by DeborahSu on Jun 13, 2013

Methylcobalamin is so much more effective than other forms of B-12, but also more expensive--normally. By using powder instead of tablets, Kirkman is able to sell it at a much more reasonable price without sacrificing quality. I love it! It dissolves quickly under the tongue and gets absorbed where it needs to be.
