Feeling a little sluggish lately? You’re not alone—and a simple B12 shot can be the change you need. At LiveVibrant Wellness and Aesthetics, one of the questions we hear most is: How long does a B12 shot last? Whether you’re navigating low energy, foggy focus, or just curious about vitamin optimization, B12 injections may be the solution!
What Is a B12 Shot and Why Might You Need One?
Vitamin B12 is a powerhouse nutrient—it fuels your red blood cells, sharpens your nervous system, and gives your metabolism a gentle nudge. But if your levels dip (and they often do!), you might feel tired, moody, or just off.
That’s where B12 shots come in. By delivering this essential vitamin directly into your bloodstream, these injections bypass digestive hiccups and go straight to work. At LiveVibrant, we offer B12 shots as part of our holistic approach to feeling vibrant from the inside out.
How Long Does a B12 Shot Last?
Let’s answer the big question: how long does a B12 shot last?
Typically, you’ll enjoy the benefits for about one to two weeks. But the exact duration depends on your body’s needs, how deficient you are, and your overall lifestyle. Your current B12 levels, metabolism, diet, and how often you receive injections all play a role.
Many of our clients feel an energy lift within 24–72 hours. If you’re starting from a significant deficiency, you might need a few weekly sessions to restore your baseline before spacing them out.
How Often Should You Get a B12 Shot?
Everyone’s wellness journey is unique, which is why we personalize your B12 shot schedule during your visit. For general wellness, a shot every two to four weeks is usually sufficient. If you’re correcting a deficiency, you might start with weekly injections and shift to monthly maintenance. Those using B12 for performance or stress recovery may benefit from biweekly boosts.
Your body gives cues—we help you interpret them.
The Feel-Good Benefits of B12 Shots
Our clients love B12 for more than just energy. Regular B12 injections support sustainable energy without caffeine crashes, lift mood, enhance focus, and promote healthier skin, hair, and nails. Many also notice a boost in metabolism that can aid in weight management. There’s even promising research connecting B12 to long-term brain and nervous system health

Any Side Effects to Be Aware Of?
In general, B12 shots are very low-risk when administered by a trained provider (like our team here at LiveVibrant). Occasionally, you might notice slight tenderness or redness at the injection site—nothing major. As always, we’ll chat through your health history to ensure it’s the perfect fit for you.
Is a B12 Shot Right for You?
B12 injections may be especially helpful if you follow a vegetarian or vegan diet, have digestive conditions like IBS or celiac, are pregnant or breastfeeding, feel chronically tired, or are over 50 and noticing changes in energy or cognition. We believe in proactive wellness. If something feels off, we’re here to explore it together.
