MIC-B12

What it is

MIC-B12 combines methionine, inositol, and choline, three compounds historically studied as lipotropic factors involved in fat and membrane metabolism in the liver, with vitamin B12, a cofactor in cellular energy metabolism that many people are found to be low in (Vitamin B12 in Health and Disease, PMC3257642). This is a longstanding compounded product with no FDA-approved brand; it is not manufactured or marketed as a standalone weight-loss drug, and Van Peptides does not present it as one. MIC-B12 is best understood as a metabolic-support adjunct that a provider may consider alongside broader lifestyle or medical guidance, not as a treatment that produces weight loss on its own.

MIC-B12 is available after a licensed-provider evaluation, and Van Peptides does not manufacture or dispense it. If a prescription is issued, it is compounded through a US-licensed compounding pharmacy rather than produced in-house.

Van Peptides connects patients with an independent network of US-licensed providers who assess whether MIC-B12 has a reasonable place in your broader plan. We do not diagnose, prescribe, or dispense, and we do not employ the providers or the pharmacy.

What the literature has explored

The individual components of MIC-B12 have distinct, separately studied research histories. Early lipotrope research examined how methionine, inositol, and choline support lipid transport and membrane synthesis in the liver, with deficiency states in animal models linked to fat accumulation in liver tissue, a body of work that is decades old and largely preclinical (Lipotropic factors and oncogenesis). Vitamin B12’s role in mitochondrial and cellular energy metabolism is separately well documented, and correcting a B12 deficiency is one of the more established interventions in this blend (Mitochondrial function and toxicity: role of the B vitamin family, PMID 16765926).

What the existing literature does not establish is that combining these compounds into an injectable blend produces weight loss by itself. We are not aware of rigorous, modern controlled trials isolating MIC-B12 as a combined product and measuring weight-related outcomes, and we do not claim it causes weight loss on its own. Providers who consider it typically frame it as a supportive adjunct alongside diet, activity, and, where appropriate, other prescribed metabolic therapies, not as a substitute for any of those. Outcomes are individual, and that caveat matters more here than almost anywhere else on this site.

We include the lipotrope and B12 literature because it is real and explains why these ingredients were combined historically, not because it proves a specific result from the combined product. If your goal is meaningful weight change, a licensed provider can discuss the full range of options, of which MIC-B12 may be one small supporting piece.
