Getting B-12 injections seems to be a hot new fad, but is it necessary? Find out here from Nutrition Diva.
Q. Getting B-12 injections seems to be a hot new fad. Can B-12 shots really boost your energy? Are they safe? Could you get the same benefit from an oral supplement?
A. Taking B-12 can definitely help boost your energy if you have a B-12 deficiency. Fatigue is a common side effect of B-12 deficiency. And injections are more effective than oral supplements for people whose bodies don’t manufacture “intrinsic factor” because this substance is required for absorption of the nutrient through the digestive tract.
The real question is how many of the starlets and reality show stars who swear by their weekly B-12 shots are actually deficient in B-12 and unable to manufacture intrinsic factor? My guess is very, very few.
This reminds me of a great scene from the movie The Birdcage. The Nathan Lane character is about to go on stage and having a complete meltdown, until his assistant (played by Hank Azaria) comes to the rescue with a “Pirin tablet.” Turns out that the Pirin tablets are actually aspirin tablets, with the “a” and “s” scraped off. But, because the character believes it to be a powerful nerve-calming drug, they get the job done.
Similarly, I suspect that the benefits of B-12 injections for healthy people are mostly imaginary. Fortunately, B-12 injections (like “Pirin” tablets) are relatively harmless.
