If you are constantly lethargic even after a full night of sleep, you may have need B12 shots. This vitamin is required in the production of red blood cells. Red blood cells transport oxygen around your body, providing the fuel your cells need to produce energy. A loss of red blood cell production will create symptoms of low energy and inability to concentrate.
A deficiency of the B12 vitamin causes anemia. An anemic individual can not efficiently convert fats and proteins into energy. This leads to the frustrating situation of difficulty losing weight despite regular exercise and a good diet.
Tryptophan is the amino acid found in foods like turkey that makes you drowsy. Our body manufactures tryptophan naturally, and it’s a big part of what helps you fall asleep at night. Vitamin B12 is a major factor in the tryptophan production process. B12 injections can help you go from restless nights to getting a good night sleep.
B12 injections are highly recommended for those who have a deficiency. The synthetic chemical, cyanocobalamin, is not easily absorbed by your body, but methylcobalamin is. Depending on your condition, you may need to get a B12 injection every few weeks until your deficiency is gone. If you have a medical condition where you are unable to absorb sufficient B12 from your diet, you will need to get a shot every month to stay healthy.
Known side effects? Rare side affect may include Pain/redness at the injection site, mild diarrhea, itching, or a feeling of swelling all over the body may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
