Improved mental clarity: B12 is essential for the production of white blood cells, which help your body fight off infections and illnesses
A B12 injection bypasses the gut entirely
Therefore, there is a very low risk of B12 toxicity, even at high doses like 1,000 mcg a day
You may want to talk with a doctor about B12 shots if you regularly experience: Persistent fatigue and lethargy Muscle aches and joint pain Loss of appetite Nausea, constipation, diarrhea, or cramping Poor memory or difficulty concentrating Mood swings Can B12 Injections Help With Mood Enhancement and Mental Clarity
Natural sources rich in B12 tend to be derived from animal foods, so anyone following a vegan or vegetarian diet may need to supplement
