Lipotropic shots combine methionine, inositol, and choline — compounds involved in fat metabolism — often with B12 added for energy. They're a supportive part of a medical weight-management program, not a standalone weight-loss drug. Here's how the two versions compare.
"Lipotropic" means fat-metabolizing. A lipotropic injection — often called a MIC shot — combines three compounds the body uses to process fat: methionine, an amino acid involved in breaking down fat; inositol, which plays a role in fat and insulin signaling; and choline, which the liver needs to move and process fat. The popular MIC/B12 version adds vitamin B12 for energy support.
These shots are used as a supportive piece of a weight-management plan. They're not appetite suppressants and they're not GLP-1 drugs like semaglutide or tirzepatide. Think of them as helping the engine run smoothly during a calorie deficit — particularly the B12 component, which targets the fatigue people often feel while losing weight.
In short: lipotropic shots support fat metabolism and energy during a weight-management program. They are a helper, not the main driver of weight loss.
Both contain the same core lipotropic blend. The difference is the added B12 — and whether you want the energy support built into one shot.

Framed honestly: these compounds support metabolic processes. They're an adjunct to — not a replacement for — the core drivers of weight loss.
Methionine and choline are involved in how the liver processes and transports fat.
The B12 in MIC/B12 targets the fatigue many people feel while cutting calories.
Choline helps the liver avoid fat buildup as part of normal metabolism.
Pairs with nutrition, activity, and where appropriate, GLP-1 therapy.
Honest about the evidence: lipotropic injections are a supportive adjunct, not a proven standalone weight-loss treatment. High-quality evidence that the shots add weight loss on their own is limited. They help most when combined with the things that actually drive results — nutrition, movement, and a structured medical program.
If you're on — or considering — a GLP-1 medication like semaglutide or tirzepatide, lipotropic and B12 shots are a common companion. At Naya we routinely pair them: the GLP-1 drives the weight loss, while the support shots help with the fatigue that's common in the early weeks of therapy.
The honest framing matters here. The support shots are for energy and tolerability — they are not a proven accelerator of the GLP-1's weight-loss effect. If a weight-loss medication is what you're after, start on the medical weight-loss side; the lipotropic shots fit in as support.
Following a structured weight-management or nutrition program
On GLP-1 therapy and feeling the early-treatment fatigue
Looking for energy and metabolic support during a calorie deficit
Wanting a clinically supervised adjunct rather than over-the-counter "fat burners"
The most common side effect is mild soreness at the injection site; some people notice a brief flush or a metallic taste. Because methionine is a sulfur-containing amino acid, patients with sulfa sensitivities should disclose it. Lipotropic injections are generally avoided in pregnancy and lactation, and in people with certain liver or kidney conditions, unless your clinician advises otherwise. We screen for contraindications at intake and review your full program before starting.
What is the difference between MIC and MIC/B12?
MIC is the lipotropic blend itself — methionine, inositol, and choline. MIC/B12 is the same blend with vitamin B12 added. The B12 is included for energy support, which many people want during a calorie deficit. If you're already getting B12 elsewhere, plain MIC may be enough; if you want the energy support in one shot, MIC/B12 is the common choice.
Do lipotropic injections actually cause weight loss?
Lipotropic injections are a supportive adjunct, not a standalone weight-loss treatment. The compounds play roles in fat metabolism and liver function, and the B12 supports energy, but high-quality evidence that the shots add weight loss on their own is limited. They work best alongside the core drivers of weight loss — nutrition, activity, and where appropriate, a medical weight-management program.
Can I combine lipotropic shots with semaglutide or tirzepatide?
Yes, and many patients do. At Naya we routinely pair lipotropic or B12 shots with GLP-1 therapy — the GLP-1 drives the weight loss, while the support shots help with the fatigue that's common early in treatment. To be clear about the evidence: the support shots are for energy and tolerability, not a proven accelerator of the GLP-1's effect.
What's in a lipotropic injection?
Methionine (an amino acid involved in fat metabolism), inositol (involved in fat and insulin signaling), and choline (used by the liver to process fat). The MIC/B12 version adds vitamin B12 for energy support.
How often do I get lipotropic shots?
Most weight-management programs use them once or twice a week. Your Naya provider will set a cadence based on your program and goals.
Can I do lipotropic shots at home?
Yes — Naya offers an at-home MIC injection kit, dispensed in person at our Chatsworth clinic only. Kits are not sold online and do not ship. A consult is required before pickup, and we teach you the injection technique before you go.
Where can I get lipotropic injections in Chatsworth or Santa Barbara?
Lipotropic (MIC and MIC/B12) injections are available at both Naya clinics — Chatsworth and Santa Barbara. The at-home MIC kit is pickup at Chatsworth only.
