B12 Injections
One of the nutrients your body uses to produce energy, build red blood cells, and keep your nervous system health
What Is a b12 injection?
A Nutrient, Delivered Directly
A B12 injection puts vitamin B12 into muscle, where your body takes it up without going through digestion first. At Pendeza we use a compounded formulation called MIC-B12. Alongside methylcobalamin, the active form of vitamin B12, it contains three other compounds: methionine, an essential amino acid; inositol, a compound your body already produces; and choline, an essential nutrient.
Vitamin B12 is one of the nutrients involved in normal energy production, red blood cell formation, and nerve health. Most people get it through food: meat, fish, eggs, dairy. Some people don’t eat much of it. Others don’t absorb it well. An injection skips the digestive step entirely.
Before your first injection you’ll complete a medical history questionnaire and meet with a provider, who reviews your history and tells you honestly whether this makes sense for you. Individual results vary.
"This is nutrient support, not treatment for a diagnosed condition."

common questions
Frequently Asked Questions
Does it hurt?
It’s a short, fine-gauge needle into muscle, and most people describe it as a quick pinch and a few seconds of pressure. Some soreness at the site over the next day is normal.
Is this a weight-loss shot?
No. Vitamin B12 supports normal energy production, red blood cell formation, and nerve health. It is not a weight-loss treatment, and we don’t market it as one. If weight is what you’re working on, our GLP-1 Therapy program is a separate service with provider oversight built around it.
Can I combine it with another treatment?
Usually, yes. B12 injections don’t interfere with facials, peels, or microneedling. Mention it when you book so we can build the time in.
Can I get one on my first visit?
Not before you’ve been screened. Every new patient completes a medical history questionnaire and meets with a provider first. In most cases the injection happens at that same visit once the review is done.
How many will I need?
Injections are given weekly. How long you continue is something you and your provider decide together based on how you’re doing and what’s changed. There’s no fixed course.
