What is Lipo-C?
Lipo-C is a defined blend of lipotropic substances combining methionine, inositol, choline and cyanocobalamin (B12). The compound supports liver fat metabolism through multiple parallel mechanisms.
The components are established and well-characterized: methionine and choline are central methyl donors, inositol is important for phospholipid structures, while B12 acts as a cofactor in methylation reactions. Research suggests the combination supports hepatic lipid metabolism, VLDL secretion and phosphatidylcholine synthesis.
Unlike peptide compounds, Lipo-C is not defined through a single receptor pathway but through parallel provision of multiple metabolic substrates. This makes it a complementary tool for metabolism research.

Comparison
What is in which blend
Components according to the TPD lexicon. MIC stands for methionine, inositol and choline. Tap a card to open its entry.
Simplified: the amounts per component differ. More components do not automatically mean more effect.
How it works
Lipo-C supports hepatic fat metabolism through the methylation axis and phospholipid metabolism:
- Methyl-donor system: Methionine and choline provide methyl groups for SAM synthesis (S-adenosyl-methionine), essential for phospholipid synthesis and fat mobilization.
- Phospholipid structure: Inositol and choline are components of membrane phospholipids, central to lipoprotein secretion.
- Cofactor supply: B12 supports methylation pool regeneration and the homocysteine pathway.
- VLDL pathway: The components together regulate the synthesis and secretion of VLDL particles from the liver.
Where it acts
Where the components act
Tap a point or a card. Colour = component. All from studies on single components, not on the blend.
- Liver
Without choline in the diet many developed a fatty liver, choline in the infusion reduced the fat1
MIC - Muscle
Choline deficiency caused muscle damage in some people1
MIC - Blood
Vitamin B12 lowered homocysteine in the blood by a further 7 percent7
B12 - Waist
Inositol slightly reduced waist size in a meta-analysis6

What the research shows
Preclinical studies document the role of Lipo-C components in lipid metabolism:
- Methylation axis: The methionine-choline axis centrally regulates phospholipid turnover and VLDL secretion. Deficiencies are associated with fatty liver.
- Phospholipid synthesis: Inositol as a component of phosphatidylinositol supports membrane signaling and lipoprotein structure.
- One-carbon metabolism: B12 and methionine together regulate the one-carbon pool, central to DNA synthesis and cell proliferation.
- Practical evidence: The combination has proven effective in American diet clinic tradition for decades, though robust clinical RCTs are rare.
Study results
What the trials measured
Interactive: switch tabs, tap points, show or hide arms. Arms are named relative to each other, no dosing advice.
Organ damage without choline1
Share with fatty liver or muscle damage on a low-choline diet, in percent
Controlled diet for up to 42 days. Those who developed organ damage got choline back, after which the values returned to normal. The study shows the need for choline, not the effect of an injection.
Liver density on CT2
Rise in Hounsfield units (HU), higher means less fat in the liver
15 patients fed almost entirely through a vein, 24 weeks. Liver values in the blood fell with choline, 10 weeks after it ended the fat came back. Choline was given in the infusion here, not as an injection under the skin.
Research status
Where the research stands
There is no registered trial of the blend. Studies on single components are shown above under the results. As of 26 Oct 2026. 10
- Preclinical No study of the blend, components known from nutrition research
- Phase 1 no registered trial
- Phase 2 no registered trial
- Phase 3 no registered trial
- Approval not yet
So far there is no registered trial in humans. 10
Side effects
Lipo-C is considered predominantly mild per research reports, as the components are individually well-characterized metabolic substrates.
- Injection site: Redness, pressure, mild burning or transient irritation are the most common observations.
- B12 component: Occasionally a sensation of warmth or mild tingling is reported shortly after application, typical for B12-containing blends.
- Digestion: With higher-dosed blends, occasionally mild gastrointestinal discomfort is described.
- Data limitations: Direct comparative studies on Lipo-C as a specific formulation are lacking. Long-term data are limited.
Storage
Lipo-C is an oil-based injection concentrate and should be stored at room temperature, protected from light. A refrigerator is not necessary and may destabilize the formulation.
Storage:
- Room temperature (18-25°C)
- Protected from light (dark bottle)
- Store dry
- Use within 60 days after opening
