This Is When to Get Vitamin B12 Injections, According to Experts

Rumor has it that vitamin B12 shots will give you a much-needed energy boost and ability to focus more. There are even claims that it's supposed to help increase your metabolism, so it's no surprise that this claim has many among us very much intrigued. But how much of this is actually true?

According to the National Institutes of Health, vitamin B12 is a nutrient that keeps the nerve and blood cells healthy, makes DNA, and prevent megaloblastic amenia, which is known to make people tired and weak. "The B12 vitamin is necessary for proper red blood cell development and formation," says Ehsan Ali, MD, the Beverly Hills Concierge Doctor. "Red blood cells hold and transport oxygen throughout our body."

Ali explains that it is primarily naturally found in red meats, so vegetarians may have problems naturally including this essential vitamin in their diet.
