What are the Benefits of B12 Injections?

Back to FAQs

Vitamin B12 is an essential nutrient that supports nerve health, mood, energy production, DNA synthesis, and more. Since the body doesn’t naturally produce B12, we receive it mainly through diet or supplementation.

B12 deficiency can lead to symptoms like:

  • Fatigue and weakness
  • Depression, irritability, and anxiety
  • Numbness in the hands and feet
  • Difficulty walking
  • Brain fog and memory issues
  • Nausea and diarrhea

Over time, a B12 deficiency can lead to serious neurological damage due to B12’s role in nerve health.

Defy Medical offers access to lab testing that can identify whether you have a B12 deficiency. If you discover a nutrition gap, you can order B12 injections via our online Patient Portal.

B12 injections deliver the vitamin directly into the bloodstream for maximum absorption, making them particularly beneficial for individuals with digestive issues that may impair oral B12 absorption.
