Adults usually get 1000 to 2500 mcg of vitamin B12 in each injection
Common side effects include mild injection site reactions (such as pain, redness, or swelling), headache, flushing, dizziness, and nausea
Ask yourself: Do you often feel tired or mentally foggy? Are you a vegetarian/vegan? Do you have absorption issues or anemia? Are you over 50? If you answered yes to any of these, its worth checking your B12 levels
Intramuscular injection bypasses this entirely, delivering hydroxocobalamin directly into the muscle where it is absorbed immediately and completely
Start with 50mg daily for the first week to assess how your body responds
Children Children need smaller amounts of vitamin B12, but deficiency can affect growth, energy levels, and neurological development
