Vitamin B12 (also called cobalamin) is an essential nutrient that your body needs to:
Convert food into energy
Support brain and nervous system function
Produce healthy red blood cells
Maintain a healthy metabolism
Regulate mood, memory, and focus
Since your body can't make B12 on its own, you must get it through food or supplements. Deficiency can lead to fatigue, weakness, brain fog, and more.
B12 injections deliver the vitamin directly into your bloodstream, bypassing the digestive system for maximum absorption. Patients often report:
Increased energy and reduced fatigue
Better focus, memory, and mental clarity
Improved mood and reduced anxiety
Enhanced metabolism and weight support
Healthier skin, hair, and nails
Stronger immune system
You may benefit from a B12 injection if you:
Feel tired, sluggish, or mentally foggy
Are vegetarian, vegan, or on a restrictive diet
Take medications like metformin or proton pump inhibitors (PPIs)
Have digestive issues that impair absorption (e.g., IBS, celiac, bariatric surgery)
Experience mood swings, irritability, or low motivation
A consultation with your provider can help determine if you have symptoms of deficiency or if you're simply looking for a wellness boost.
It depends on your goals and current B12 levels. Most common plans include:
1x/week for 4–6 weeks for energy or deficiency support
1–2x/month for general wellness or maintenance
Your provider will create a custom schedule based on your needs
Yes. Vitamin B12 is water-soluble, which means your body uses what it needs and eliminates the rest. Side effects are rare and typically mild. These may include:
Temporary soreness or redness at the injection site
A mild feeling of energy or alertness right after the shot
Rarely, mild dizziness or a flushed feeling (usually short-lived)
Some people feel the energy boost within 24–72 hours, while others notice improvements over the course of a few sessions. If you’re B12-deficient, you may feel a dramatic difference. For general wellness, the effects tend to build over time.
Yes! B12 is commonly paired with:
MIC (Methionine, Inositol, Choline) for fat-burning
Glutathione for detox and skin health
B-complex or Vitamin C for a full energy and immunity boost
Ask your provider about building a custom injectable wellness plan.
