Methionine
The "M" in MIC Injection, is an essential amino acid, which means that it is not synthesized in humans. This amino acid acts as a lipotropic agent which: assists in the breakdown of fats within the liver; helps to lower cholesterol thereby preventing excess fat buildup in the liver and throughout your body’s circulatory system; is helpful in preventing and relieving fatigue; and is useful in some cases of allergies by virtue of its ability to reduce histamine release.123
One of the sulfur-containing amino acids (along with cysteine and cystine), methionine is important (essential) to many bodily functions and must be directly consumed through supplementation or methionine-containing proteins. Foods which contain high levels of methionine include cheese, eggs, fish, meats, spinach, potatoes, Brazil nuts, sesame seeds, and select other plant seeds. However, by injecting methionine into your muscles you can rapidly achieve high concentrations which many researchers and physicians believe results in more effective mobilization and elimination of abnormal fatty deposits. Other reported benefits of methionine include improvement of: liver disease; skin tone and elasticity; nails; hair; and cardiovascular and muscular functions, through its role in the production of creatine. It has also been used to treat premature ejaculation, chronic depression, pancreatitis, Parkinson’s disease, and AIDS myelopathy. More specifically, clinical research has clearly demonstrated methionine’s ability to “…strongly improve the alcohol-induced histological changes in the liver. Triglyceride content of the liver was found to decrease in a dose-dependent manner with increasing methionine ingestion.4
 
Inositol
The "I" in MIC Injection, is a B-vitamin that promotes: the health of cell structures and nerve synapses; aids in the metabolism of fats; helps reduce blood cholesterol; and participates in the action of serotonin, a neurotransmitter known to control mood and appetite.567
Also known as myo-inositol, inositol is best described as a carbocyclic polyol, which forms the basis for many signaling and secondary messenger molecules. As such, it is involved in many biological processes, including the breakdown of fats, the reduction of serum cholesterol, serotonin activity modulation, gene expression, and insulin signal transduction. It is not considered a vitamin because your body is unable to synthesize it. However, it has been shown to be helpful for the treatment of depression, panic disorder, polycystic ovarian syndrome, and fatty liver. It also important for optimal brain function.89
Inositol deficiency may manifest as symptoms of constipation, high cholesterol, vision problems, and hair loss. Although it is naturally found in certain foods such as nuts, beans (especially red beans and kidney beans), grains, cantaloupe melons, and oranges, it is more effective in breaking down fat when given as an intramuscular injection. 
 
Choline
The "C" in MIC Injection, is an essential nutrient that helps to support the liver in its processing and excretion of chemical waste products. Moreover, it is required for the transport and metabolism of fats and cholesterol, which is important for the healthy support of the endocrine, cardiovascular, and hepatic systems.
A few specific studies have clearly demonstrated:
“Choline supplementation normalized cholesterol metabolism, which was sufficient to prevent nonalcoholic steatohepatitis development and improve liver function. Our data suggest that choline can promote liver health by maintaining cholesterol homeostasis.”10 “Choline induces glucose and insulin intolerance in Pemt(-/-) mice through modulating plasma glucagon and its action in liver.”11 Choline supplementation decreased the concentration of liver triacylglycerol during the first 4 wk after parturition. Results from this study suggest that hepatic fat export in periparturient dairy cows is improved by choline supplementation during the transition period and this may potentially decrease the risk for metabolic disorders in the periparturient dairy cow.”12 Choline is also known to be involved in the synthesis of carnitine, cell membrane phospholipids, and the neurotransmitter acetylcholine. It is a major source for methyl groups via its metabolite trimethylglycine (betaine) that participates in the S-adenosylmethionine synthesis pathways. Lastly, choline has also been shown to specifically aid with memory, and to support the maintenance of a healthy nervous system.1314 Food sources of choline include peanuts, soybeans, wheat, chicken, fish, beef, cauliflower, eggs, and lettuce.
