MIC ("Fat Burning") Injections and
Their Role in Weight Management

MIC is an acronym for the compounds:  L-Methionine, Inositol and Choline.  

These are lipotropic agents which help with the breakdown of fat during metabolism in the body. 

Many weight loss clinics call them “fat-burning” injections.

What are MIC Injections?

As part of a successful VLCD (very low calorie diet) medically supervised weight loss program, physicians add MIC injections as a therapy to augment a patient’s weight loss experience.  

Since the Clean Start Weight Loss program releases much fat into the body, lipotropic injections help move fat out of the liver. 

Some accelerated  hormone based weight loss programs enhance their MIC injections with associated fat burning compounds such as Cyanocobalamin. Or they add additional injections to complement their MIC injection protocol, such as injections of B6 and/or B12.

What makes up a MIC Injection?

A Methionine Inositol Choline (MIC) injection consists of a formula of lipotropics, compounds that help break down fat. The primary compounds in the formula–methionine, inositol, choline–work to metabolize fat cells and assist in the elimination of stored fat deposits in the liver and body.


L- Methionine is one of eight essential amino acids that are the building blocks for proteins but which cannot be produced in the body.  

Aside from injection or ingestion as a supplement, L-Methionine can be found in meats and dairy products, as well as spinach, potatoes, Brazil nuts and sesame seeds.  

L-Methionine is useful in the treatment of liver disease and is a recommended supplement for vegetarians.

For weight management, L- Methionine helps the body process and eliminate fat.  It is a required amino acid in the production of cysteine and taurine, which help the body eliminate toxins.


Inositol is a carbohydrate, but is not considered a sugar, and was once considered a member of the vitamin B complex. But since the body is able to synthesize it, it is not a classic vitamin.  

It is also found predominantly in fruits such as cantaloupe and oranges, as well as bananas, kidney beans, raisins, and peanuts.

In the management of weight, inositol, when used in combination with other B complex vitamins, helps the liver break down fats in the body.

When used in combination with other compounds in a MIC injection, especially choline, inositol forms lecithin which is known to aid in the metabolism of fat.

Choline is considered an essential nutrient that, while produced in the liver, is generally not produced in sufficient quantities.  

Like inositol, it is often grouped within the B complex of vitamins, although it is not a true B vitamin.

Choline is required in the regulation of the kidneys, liver and gallbladder.

As part of a weight loss program, choline is essential for fat metabolism, it functions as a methyl donor and it assists detoxification reactions in the liver.

Soybeans along with eggs are two of our best choline-based food sources, as well as beef liver, cauliflower, tofu and almonds.

The components of a MIC injection, especially inositol and choline, have been found to improve mental function and improve feelings of depression.

As part of a successful physician-supervised VLCD weight loss program, MIC injections are typically given weekly for the duration of the program.

How long do MIC injections (lipotropic injections) last?

How long lipotropic injections stay in your system depends on several factors, such as your own personal metabolism and how often the injections are administered. In general, though, these injections last about a week or two.

How long does it take to see results from MIC injections?

It often takes up to 3 to 4 weeks to start noticing the weight loss benefits of MIC injections. However, results are dependent on your diet and exercise. Additionally, the effects of a boosted metabolism might be felt or noticed prior to seeing the weight loss begin.

What are the benefits of Lipotropic Injections (MIC injections)?

Lipotropic injections are safe, give energy when reducing caloric intake, and are often used in diet plans that initiate additional weight loss and enhance weight loss results. The nutrients in lipo shots are a class of agents that play important roles in the body’s use of fat. These compounds help the liver process those fat cells out of the body.

Do MIC injections hurt?

When MIC Injections are administered correctly you may feel a slight pinch, a local warming under the skin or a small tightness in the general injection location. If needed, a topical or local numbing agent could be applied.

Are MIC injections safe?

For most patients MIC Injections are safe. Most patients will experience no side effects other than the induced weight loss that the MIC Injections are created to achieve. There is the possibility of a small number of patients experiencing side effects, such as an upset stomach.

What does MIC do to the body?

Lipotropic Injections promote the removal of fat from the liver and reduce the production of fat.

How many MIC shots do you need?

The exact dosage of your injections will depend on what ingredients are being used. Regardless of the dosage, your practitioner may recommend weekly shots for several weeks. This may be for a few months at a time or until you reach your weight loss goal.

Where do you inject MIC injections?

The fat burning injections site can be the buttocks, thigh, hip or upper arm.

Lipo Shots, Fat Burning Injections

These terms all refer to the same type of injections. These are intended to complement other aspects of a weight loss regimen, including exercise and a low-calorie diet.

What is the Difference Between B12 Shots and Lipotropic Shots?

While both contain Vitamin B12, Lipotropic injections offer additional nutrients that further enhance weight loss.

Do MIC shots work for weight loss?

The answer is…. it depends. 

Many clinics sell these as “fat-burning” injections, and many people think they dissolve fat. But the science behind the MIC injections does not support that claim.  

What they do is help the liver process fat cells that have already been broken down by the body, they do not break down fat cells themselves.  

So in conjunction with a rapid medically supervised weight loss program or a body sculpting treatment (like CoolSculpting, Physiq, SculpSure) that breaks down fat cells, they do indeed help the liver process those fat cells out of the body.

The bottom line is that if you are not doing anything to break down your fat cells (ie medically supervised weight loss program or fat elimination procedures like CoolSculpting, Physiq, SculpSure), these injections will not help you lose weight or kill fat cells.
