Vitamin B12 helps in the production of healthy red blood cells.

If your levels of B12 are low then you may feel sluggish, irritable or lack concentration. This is because your red blood cells are not transporting oxygen to your organs efficiently.

You can ensure your levels of B12 are sufficient by eating things such as beef, broccoli, egg, salmon or having regular B12 injections.

If you are getting enough vitamin B12 from your diet, then B12 injections won’t further boost your energy levels.

B12 injections can give you an energy boost, can improve sleep, lethargy, improve both digestion and metabolism.
