Some people are at higher risk of a B12 deficiency than others, including older adults

As we previously mentioned, it's estimated that your body can only absorb approximately 10mcg of B12 out of a 500mcg supplement, so it's always in your best interest to plan accordingly by choosing a vitamin B12 supplement that will contain much more than you what you theoretically need to meet your daily requirements

Potential Side Effects While Vitamin B12 injections are generally safe, some people may experience mild side effects, including: Pain or redness at the injection site Mild diarrhea Itching or rash Headache Dizziness Severe allergic reactions are rare but require immediate medical attention
