2. **Vitamin B12:** Vitamin B12 absorption is a more complex process. It requires a protein called intrinsic factor, which is produced by the stomach lining. In the small intestine, intrinsic factor binds to vitamin B12, allowing it to be absorbed into the bloodstream.

It's worth noting that factors like age, medical conditions, medications, and diet can influence the absorption of B vitamins. For instance, certain gastrointestinal disorders or surgeries may affect the absorption of vitamin B12. A well-balanced diet and healthy gut function are essential for proper vitamin B absorption.
