Lipotropic Injections
MIC and B12 injections that support fat metabolism, boost energy, and enhance your weight loss results. A powerful complement to GLP-1 therapy or a standalone option for metabolic support at Rewind Anti-Aging of Miami.
Fat-Metabolizing Amino Acids & Vitamins
Lipotropic injections — commonly known as MIC injections or MIC/B12 injections — are intramuscular injections containing a combination of amino acids and vitamins specifically chosen for their roles in fat metabolism, liver function, and energy production. The term "lipotropic" literally means "fat-loving" and refers to compounds that promote the transport and metabolism of fat in the body.
The core formulation consists of four key ingredients: methionine, inositol, choline, and vitamin B12. Together, they support the biochemical pathways that your liver uses to break down and export fat — pathways that can become overtaxed during periods of rapid weight loss or caloric deficit. Learn more about how these therapies fit into the broader landscape in our guide to the best peptides for weight loss.
At Rewind Anti-Aging of Miami, lipotropic injections are one component of our comprehensive weight loss program. They are most commonly used alongside primary weight loss medications like semaglutide or tirzepatide, but are also available as a standalone option.
How Each Ingredient Works
Understanding what is in your injection — and why — is part of being an informed patient.
Methionine
Fat Breakdown in the Liver
An essential amino acid that supports fat breakdown in the liver and prevents hepatic fat accumulation. A precursor to S-adenosylmethionine (SAMe) and the antioxidant glutathione, which protects liver cells from oxidative damage during accelerated fat metabolism.
Inositol
Fat Transport & Insulin Regulation
Helps redistribute body fat by supporting the transport of fats out of the liver. Functions as a secondary messenger in insulin signaling pathways, helping cells respond more effectively to insulin. Also has mood-stabilizing properties that reduce stress-related eating.
Choline
Fat Metabolism & Liver Function
Required for the synthesis of VLDL particles — the transport vehicles your liver uses to export fat into the bloodstream. Without sufficient choline, fat accumulates in the liver. Studies estimate roughly 90% of Americans do not consume adequate choline through diet alone.
Vitamin B12
Energy & Metabolism
Essential for energy production, red blood cell formation, and neurological function. IV delivery bypasses GI absorption issues for rapid, reliable B12 availability. Many patients report a noticeable boost in energy and mental clarity within days of their first injection.
Benefits of Lipotropic Injections
The combined effects of MIC and B12 deliver a range of benefits that support weight loss, metabolic health, and overall well-being.
Enhanced Fat Metabolism
Support your liver's ability to break down, transport, and eliminate fat, particularly during active weight loss when fat mobilization is accelerated.
Increased Energy
B12 and MIC ingredients help combat the fatigue that often accompanies calorie restriction and weight loss medication.
Liver Support & Protection
Methionine and choline protect liver cells and prevent fat accumulation — especially important for patients losing weight rapidly.
Mental Clarity & Focus
B12's neurological benefits and inositol's role in neurotransmitter signaling contribute to improved cognitive function and reduced brain fog.
Mood Improvement
Inositol and B12 both support mood regulation, helping reduce anxiety, irritability, and emotional eating patterns that can derail weight loss.
Insulin Sensitivity
Inositol's role in insulin signaling may help improve how your body processes and stores glucose, reducing a key metabolic driver of weight gain.
How Lipotropic Injections Complement Other Treatments
Lipotropic injections work best as a supporting treatment that enhances the results of a primary intervention.
Alongside GLP-1 Medications
GLP-1 drugs produce significant fat loss, which places increased demands on the liver. Lipotropic injections support liver function during this process and provide the energy boost that counters GLP-1 dose titration fatigue. This is one of the most popular protocols in our clinic.
Alongside Hormone Therapy
Patients on hormone therapy — particularly testosterone or thyroid optimization — often see improved body composition results when lipotropic injections are added. The B12 component supports the increased energy demands of an optimized metabolism.
Learn more →Alongside Exercise Programs
Lipotropic injections support the metabolic processes that convert stored fat into usable energy during workouts. The B12 energy boost can improve exercise tolerance and recovery.
Who Are Lipotropic Injections For?
- Patients on GLP-1 medications who want to maximize fat metabolism and support liver function
- Patients with mild weight loss goals (10-20 pounds) who prefer a lighter-touch approach
- Anyone seeking an energy boost — even without active weight loss goals
- Patients concerned about liver health, particularly those with fatty liver disease
- Patients on hormone replacement therapy optimizing body composition
- Patients experiencing fatigue, brain fog, or low energy
Timeline for Results
Most patients notice increased energy within the first 1-2 injections, often within a day or two of their first dose.
Improved focus and reduced brain fog typically develop with consistent injections.
Metabolic benefits become measurable, especially when combined with dietary changes, exercise, or a primary weight loss medication.
Visible body composition changes depend on your total program — lipotropic injections accelerate results but require a caloric deficit to produce measurable fat loss.
Side Effects & Safety
Lipotropic injections are among the safest treatments in our clinic. The ingredients are naturally occurring substances that your body already produces and uses. Serious adverse effects are extremely rare.
Common Side Effects (Mild)
- Injection site discomfort
Brief pinch during injection and occasional mild soreness for a few hours.
- Mild warmth or flushing
Brief warming sensation after injection, particularly with B12. Resolves quickly.
Who Should Not Receive
- Known allergy to methionine, inositol, choline, or B12/cobalt
- Leber's disease (hereditary optic neuropathy)
- Certain advanced liver conditions (consult your hepatologist)

Frequently Asked Questions
What are lipotropic injections made of?
Our lipotropic injections contain a combination of methionine, inositol, and choline (collectively known as MIC) plus vitamin B12. Methionine is an essential amino acid that supports fat breakdown in the liver. Inositol helps transport fat and regulate insulin. Choline is essential for fat metabolism and liver function. B12 supports energy production, red blood cell formation, and neurological function. Some formulations may also include additional B vitamins or L-carnitine depending on your provider's recommendation.
How often do I need lipotropic injections?
Most patients receive lipotropic injections one to two times per week. The frequency depends on your weight loss goals, current treatment plan, and how your body responds. Each injection is a quick visit — typically less than 10 minutes — or can be self-administered at home after proper training from our clinical team.
Do lipotropic injections actually work for weight loss?
Lipotropic injections support your body's natural fat metabolism processes but are not a standalone weight loss solution on their own. They work best as part of a comprehensive program that includes dietary modifications, exercise, and in many cases a primary weight loss medication such as semaglutide or tirzepatide. Patients most commonly report increased energy, improved mental clarity, and enhanced fat loss when combined with other treatments.
Are lipotropic injections safe?
Yes, lipotropic injections are generally very safe and well-tolerated. The ingredients — methionine, inositol, choline, and B12 — are naturally occurring substances that your body already uses. The most common side effect is mild discomfort at the injection site. Allergic reactions are rare. They are not recommended for patients with known B12 sensitivity or certain liver conditions. Your provider reviews your health history before prescribing.
Can I get lipotropic injections while taking semaglutide or tirzepatide?
Absolutely, and many of our patients do exactly that. Lipotropic injections complement GLP-1 medications by supporting liver function and fat metabolism during the accelerated fat loss that GLP-1 drugs produce. The B12 component also helps combat the fatigue some patients experience during the early weeks of GLP-1 therapy. There are no known drug interactions between MIC/B12 injections and GLP-1 receptor agonists.
How quickly will I notice results from lipotropic injections?
Most patients notice an increase in energy within the first one to two weeks, often after just a few injections. Changes in body composition and fat loss take longer and depend heavily on your overall program — diet, exercise, and whether you are using a primary weight loss medication alongside the injections. Lipotropic injections are a supporting treatment, not a rapid weight loss intervention on their own.
