B12 is a water-soluble B complex vitamin that aids in the production of red blood cells. It’s a vitamin that helps treat anemia, helps to prevent or treat low vitamin B12 levels, helps metabolize fat and carbohydrates, and synthesizes protein. Your body doesn’t naturally make B12, so you get it from eating animal byproducts, or supplementing.
Some patients are unable to break down the protein to absorb vitamin B12 into the bloodstream while others are at risk for low levels of B12 because the food consumed doesn’t contain high enough amounts of B12, such as vegetarians or vegans. Patients can also be at risk for low levels of B12 if they are taking certain medications such as antacids or antihistamines, which can block the absorption of B12.
What can vitamin B12 do for me?
Vitamin B12 is a crucial vitamin needed for metabolic and hormonal functions. It helps with the production of our digestive enzymes and the transporting of nutrients in and out of our cells. Other roles of vitamin B12 is that it helps in the conversion of homocysteine to methionine, which protects cardiovascular health, metabolizing protein and fat, and it also plays a role in fetal development during pregnancy.,
B12 injections have great benefits and can last in your system for up to a month. Many people prefer B12 injections versus taking a daily vitamin. B12 can also:
