The same ingredient, carried differently.

What each form is, and where it fits in a formula. Measured findings carry the study that reported them.

• Methylcobalamin

  Cobalamin carrying a methyl group on the upper axial position of the corrin ring, the coenzyme form used by methionine synthase.

  Fits

  Products aiming to supply a coenzyme form directly, and sublingual formats where a coloured, light-sensitive powder is pressed into a small tablet.

  Trade-off

  Photolabile and less thermally stable than cyanocobalamin, so it needs opaque packaging and a shorter stated shelf life.

Descriptions of the form itself, read from the cited studies. Not a comparison between products and not a statement about any individual.
