MIC B12 injections, prescribed online

What is MIC B12?

MIC is shorthand for three ingredients: Methionine, Inositol, and Choline. Add B12 (methylcobalamin) and you have MIC B12, a compounded injection usually given once a week into the muscle.

The B12 part has the clearest job description. Your body uses it to keep blood and nerve cells healthy and to make DNA. Run low and you can feel tired and weak, because low B12 can lead to a type of anemia. Methionine, inositol, and choline are nutrients your body also uses; in MIC B12 they ride along with the B12 as a supporting cast.

It is not a weight loss drug and it is not a shortcut. It is one small, weekly piece of a plan your provider builds with you.

What MIC B12 can and can't do

What it can do

• Fill a B12 gap. If your levels run low, B12 helps your body make healthy red blood cells, and that tired, heavy feeling often eases as levels come back up.
• Skip the absorption problem. Some people have trouble absorbing B12 from food, including people who take acid reducers or metformin and people who have had certain stomach surgeries. B12 injections go around the gut.
• Fit a routine. One quick shot a week, on the same day as your other habits.

What it can't do

• Boost energy you already have. In people whose B12 is already sufficient, extra B12 does not appear to improve performance or endurance.
• Replace food, movement, or sleep. It works best as a sidekick to the plan, not the plan.

What to expect

Expect a weekly injection and a provider who checks in on how you feel. If your B12 was running low, people often notice energy changes first. If it wasn't, the honest answer is you may not feel much, which is exactly why a provider reviews your history before prescribing.

MIC B12 side effects

The most common one is the obvious one: a sore, red, or slightly swollen spot where the needle went in. Rotate sites and it usually stays minor.

B12 itself has a good safety record. There is no official upper limit for it because it is generally considered safe even at high doses. That does not mean "anything goes." Allergic reactions to any injection are possible, and the other ingredients and the compounding itself matter, so tell your provider about allergies, medications, and supplements before you start.

Hives, trouble breathing, or swelling of the face, lips, or tongue means stop and get medical help right away.

Who it's for

Adults looking for B12 and energy support who meet clinical eligibility criteria. A licensed Fitish provider reviews every intake. Especially worth a conversation if you take metformin or an acid reducer, eat little or no animal food, or have had weight loss surgery, since those can all affect B12 levels.

Not sure if your B12 is low? Start the intake and a licensed provider will take it from there.

Frequently asked questions

What is MIC B12?

A compounded injection that combines methionine, inositol, and choline with vitamin B12. It is usually given once a week into the muscle and prescribed as part of a broader plan, not as a standalone weight loss treatment.

What are MIC B12 injections used for?

Mostly B12 support, especially for people whose levels run low or who don't absorb B12 well from food. Your provider decides whether it fits your history and goals.

Is MIC B12 a peptide?

No. B12 is a vitamin, and methionine, inositol, and choline are nutrients. It often gets lumped in with peptides because it is an injectable you get through a wellness provider. If you are curious about actual peptides, see our options in The Clinic.

Is there a MIC B12 pill?

B12 comes in pill form, and some companies sell oral "MIC" blends. Fitish MIC B12 is an injection only. If you have questions about the route, bring them up with your provider during intake.

What are the side effects of MIC B12?

Most commonly a sore or red spot at the injection site. Allergic reactions are possible with any injection. See the full list in Safety Details below.

How is it taken?

Typically a weekly intramuscular injection. Your provider confirms your routine in your patient portal.

How much does it cost?

$109 for a monthly supply, including your provider consult, the medication if approved, and shipping.

Can I pay with my HSA or FSA?

Sometimes. Some plans and cards will go through and others will not, and that part is largely outside our control. HSA and FSA rules generally cover the treatment of a diagnosed condition rather than general wellness, and card networks treat compounded telehealth prescriptions inconsistently, so a card can be declined at checkout. Eligibility is determined by your plan and your plan administrator, not by us. If you want to use those funds, check with your administrator first, pay with any other card, and submit for reimbursement. Your provider can discuss whether a Letter of Medical Necessity fits your situation.
