You may have heard of people taking vitamin B12 supplements of shots. This may leave you wondering if you would benefit from B12 vitamin shots or supplements. B 12 is necessary for the development of red blood cells, proper neurological functions, and anemia prevention. Vit B-12 is also needed for the production of DNA. While weight loss clinics claim to have marvellous results from delivering Vitamin B-12 shots and supplements, there is no hard scientific evidence to back this up.
You probably aren’t B 12 deficient (a simple blood test can let you know if you are), and your body is going to store all the extra vitamin B until you need it at a future date. While a vitamin B shot may help you if you are truly anemic or deficient (which can be determined by a blood test), it will not improve your metabolism or make you more energetic if you are already getting enough B 12 Vitamin. Make sure you ask your doctor before you start taking any sort of B-12 shots or taking large doses of supplements because too much vita B-12 can interfere with the effectiveness of particular medications you may be taking.
