Overview
Lipo-C with B12 (MIC) at a glance
MIC is an abbreviation of methionine, inositol and choline, three small molecules involved in lipid and one-carbon metabolism. The product Vesta lists as Lipo-C with B12 adds vitamin B12 to this combination. Unlike the other Lipo-C listings, its ingredients are named, although their amounts are not published.
All four ingredients are well characterised: L-methionine is an amino acid, myo-inositol is a sugar alcohol, choline is a quaternary ammonium cation supplied as a salt, and cyanocobalamin is the cyanide-containing form of vitamin B12. The table on this page gives each formula and mass from PubChem.
Vesta lists the product as a kit of 10 vials at 10 mL per vial. The physical form of the vial and the concentration of each ingredient should be taken from the batch documents.

Quality
Analytical notes for batch documents
- Three of the four ingredients have little or no UV absorbance at the wavelengths used for peptide HPLC. Ask which detector and method were used for any purity or assay value, and for the amount of each ingredient in mg/mL.
- Choline is reported as a cation of mass 104.1070. The salt form (chloride, bitartrate or another) changes the mass of the supplied material, so ask which salt is present.
- Cyanocobalamin is intensely coloured (red) and absorbs near 361 nm and 550 nm, which allows a simple UV-visible check of its presence and amount. It is also sensitive to light.
- Methionine can oxidise to methionine sulfoxide (+15.995 Da). A mass spectrum showing that shift on the methionine ion points to oxidation in the material.
- Myo-inositol is one of several inositol stereoisomers. Confirm that the isomer on the formulation sheet is myo-inositol.
