B12 Shots are an excellent way to gain energy quickly and boost your overall health. B vitamins are essential for the body to function properly. They assist with metabolism and boost energy so you can be alert throughout the day. Other key benefits that B12 shots feature include:
Increased production of red blood cells
Increased energy and metabolism
Enhanced neurological health
B12 shots are administered intramuscularly in either the shoulder or buttocks. There are no toxic side effects that are associated with getting a B12 injection at appropriate levels. You may receive an occasional bruising and soreness at the injection site, but those symptoms normally subside within 1-3 days.
