Why B12 Shots are Better than Oral Supplements While oral B12 supplements can work for many people, there are several reasons why B12 methylcobalamin injections might be a superior choice for others
Symptoms may include: Constantly feeling tired or chronic fatigue Muscle aches and weakness Joint pain Difficulty breathing or shortness of breath Feeling dizzy Poor memory Inability to concentrate well Mood changes, like increased depression and anxiety Having abnormal heart problems, such as palpitations Poor dental health, including bleeding gums and mouth sores Digestive problems like nausea, diarrhea or cramping A poor appetite A more serious deficiency can also cause a form of anemia called pernicious anemia, a serious condition that can cause memory loss, confusion and even long-term dementia
Studies as early as 1998 validate the use of correct oral treatment as being equally effective as injections, with a conclusion that stated: In cobalamin deficiency, 2,000mcg of cyanocobalamin administered orally on a daily basis was as effective and may be superior for raising blood B12 levels as 1,000mcg administered intramuscularly on a monthly basis
However, the quality and safety standards of international pharmacies can be questionable
