- Red Blood Cell Formation: It’s super important for making red blood cells. These guys are like the delivery trucks of your body, carrying oxygen to all your cells and tissues. Without enough B12, you can’t make enough red blood cells, which means less oxygen, and that can lead to feeling tired and weak.
- Nervous System Health: This is a huge one. B12 helps create myelin, which is like the insulation around your nerves. This insulation allows nerve signals to travel smoothly and quickly. It also helps make neurotransmitters like serotonin and dopamine, which are pretty famous for their roles in mood and well-being.
- DNA Synthesis: Vitamin B12 is necessary for creating DNA, the genetic material that’s in all your cells. Proper DNA creation is vital for cells to work correctly.
- Protein Metabolism: It’s also needed for processing proteins, which are the building blocks for pretty much everything in your body – organs, tissues, you name it. B12 helps keep them structured and functioning right.
