Cyanocobalamin is a man-made form of vitamin B12. It is used to prevent and treat low blood levels of this vitamin. Vitamin B12 helps to utilize fats and carbohydrates for energy and make new proteins. Vitamin B12 is important in the maintenance of our metabolism, blood cells, and nerve function. Most people get enough vitamin B12 in their diet, but some need supplementation. Certain health conditions such as intestinal or stomach problems, poor nutrition, cancer, HIV, pregnancy, old age, veganism, and alcoholism can cause vitamin B12 deficiency. Low levels of vitamin B12 can lead to fatigue and anemia in milder cases. More serous B12 deficiencies have the potential to impair heart and neurological function, leading to a wide range of serous symptoms, including but not limited to tinnitus, severe joint pain, memory problems, depression, anxiety, poor muscle function, ataxia, and changes in reflexes. Infertility can also occur in individuals with insufficient B12. Early intervention and treatment of B12 deficiencies are key to maintaining healthy bodily function.
