Vitamin B12 (Methylcobalamin) vs MIC Blend (Lipo-C + B12)
Vitamin B12 (Methylcobalamin) (Essential vitamin (cofactor)) and MIC Blend (Lipo-C + B12) (Lipotropic research solution) are documented as co-studied in the PeptiDex library. This page puts the two entries side by side on class, molecular weight, half-life, origin, mechanism and studied research areas — every value taken from the entry it belongs to.

| Origin | Vitamin B12 (cobalamin) is an essential water-soluble vitamin containing a central cobalt atom. Common forms include methylcobalamin (the active methyl-donor form), hydroxocobalamin, and cyanocobalamin. It is not a peptide. | MIC is a lipotropic blend named for its three core components: Methionine, Inositol, and Choline, frequently formulated with added Vitamin B12. It is a compounded wellness formulation, not a single molecule or a peptide. |
“Not documented” means the PeptiDex entry records no value for that field. Nothing on this page is estimated, and no figure is carried over from one compound to the other.
How Vitamin B12 (Methylcobalamin) works
B12 is a required cofactor for two key enzymes: methionine synthase (which regenerates methionine from homocysteine and requires methylcobalamin, supporting cellular methylation) and methylmalonyl-CoA mutase (which requires adenosylcobalamin). Through these roles it supports DNA synthesis, red blood cell formation, and nervous system function.
How MIC Blend (Lipo-C + B12) works
The blend combines methyl-donor and lipid-handling compounds: methionine (an essential sulfur amino acid and methyl donor), inositol (a carbocyclic sugar involved in lipid signaling), and choline (required for phospholipid synthesis and hepatic fat export), often with B12 to support one-carbon metabolism. The proposed rationale is supporting the liver's processing and export of fat. Controlled clinical evidence specifically supporting MIC injections for weight loss is limited.
Mechanistic descriptions reflect published research-literature understanding and are quoted from each compound's own entry. Much peptide research is preclinical (in-vitro or animal-model); mechanism in humans may differ and is not established for many compounds.

What sets each apart
Vitamin B12 (Methylcobalamin)
Unlike the peptides and research small molecules here, B12 is a recognized essential nutrient with established physiological cofactor roles.
MIC Blend (Lipo-C + B12)
MIC is the core methionine/inositol/choline lipotropic blend; Lipo-C is a related, often broader formulation that may add L-carnitine and/or additional B vitamins.

Frequently asked questions
Why is methylcobalamin included in metabolic and lipotropic research blends?
B12 is frequently combined with lipotropic agents (such as MIC/lipo-C compounds) in metabolic research formulations because of its role in energy and one-carbon metabolism. In those contexts it is an adjunct/cofactor rather than a primary fat-loss agent, and claims about standalone fat-loss effects are not well supported.
What is methylcobalamin and how does it differ from cyanocobalamin?
Methylcobalamin is a naturally occurring, bioactive coenzyme form of vitamin B12 in which a methyl group is bound to the central cobalt atom. Cyanocobalamin, the common synthetic supplement form, instead carries a cyanide group and is valued for stability and cost. Methylcobalamin is one of the two active B12 coenzymes used directly by B12-dependent enzymes.
What enzymatic role does methylcobalamin play?
Methylcobalamin is the specific B12 form used by methionine synthase (5-methyltetrahydrofolate-homocysteine methyltransferase, MTR), which remethylates homocysteine to methionine. This links B12 to folate and one-carbon/methylation metabolism. The other active coenzyme form, adenosylcobalamin, serves a different mitochondrial enzyme.
What is a MIC blend?
MIC stands for Methionine, Inositol, and Choline - the three lipotropic compounds at the core of the blend, typically combined with vitamin B12. It is a mixture of small-molecule nutrients, not a peptide. It is used in a metabolic/lipotropic research and compounding context.
How does a MIC blend differ from Lipo-C?
The MIC blend is the core methionine/inositol/choline formula (commonly with added B12). Lipo-C generally builds on this base by adding L-carnitine and further B-vitamins or cofactors. The two are closely related members of the same lipotropic family, with Lipo-C being the more extended formulation.
Why is B12 usually added to MIC?
Vitamin B12 (cyanocobalamin) is commonly added for general energy and metabolic support and because it is well tolerated in injectable form. Its inclusion is why the blend is often written as 'MIC + B12,' though the exact concentrations vary by compounding source.
