Some conditions, like pernicious anemia, make it hard for your body to absorb B12
Before taking this medicine You should not use Vitamin B12 if you are allergic to cyanocobalamin or cobalt, or if you have Leber's disease (an inherited form of vision loss)
But including foods high in these vitamins (like whole grains, meats, eggs, dairy, leafy greens, nuts) as tolerated can help maintain levels once the course of injections is over
These injections are especially beneficial during cold and flu season, offering antioxidant protection and improved energy levels

Rinsing a plastic bottle may remove some residue, but this isnt enough to fully disinfect it especially after multiple uses
