Frequently Asked Questions Vitamin B12
What is Vitamin B12 and why is it important?
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.
What are the benefits of Vitamin B12 injections?
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
How do I know if I need a B12 injection?
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.
How often should I get a B12 shot?
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
Are B12 injections safe?
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)
Who shouldn’t get a B12 injection?
B12 is safe for most people. You may need to consult your provider first if you:
Have a known allergy to cobalt or B12
Have kidney disease or Leber’s optic neuropathy
Are pregnant or breastfeeding (dosing may be adjusted)
