Could Vitamin B-12 Shots Be Your Weight Loss Solution?

Myth Busters Series: Separating Food & Exercise Facts from Fiction

There are thousands of clinics across the nation that offers vitamin B-12 injections as part of their weight loss program. Proponents of these shots claim that they give you more energy, increase your metabolism, and therefore help you shed unwanted pounds. Sounds great, right? So why aren’t all overweight individuals getting vitamin B-12 shots help with their weight loss?


What does vitamin B-12 do for the Body?

Vitamin B-12 is a water-soluble B complex vitamin that is found naturally in numerous food items, including meats, fish, and dairy products. Along with being commonly added to many food items, B-12 is available in several different forms as a supplement. The body needs this vitamin to keep nerve and red blood cells healthy and to make DNA. It also helps prevent and treat a type of anemia called megaloblastic anemia, which causes severe weakness and fatigue.

So how can Vitamin B-12 help you lose Weight?

Unfortunately, the experts will tell you that this is just another quick-fix weight loss fad, one that will probably bring your hopes to lose weight down, more than your unwanted pounds. Research shows that unless you have a vitamin B-12 deficiency (which is rare considering it is found naturally in so many foods), getting vitamin B-12 shots will not help you to lose weight.

There is, however, the possibility that someone may be unable to properly absorb vitamin B-12 from natural food sources. In which case, supplementation could be needed and possibly aid in weight loss. Your doctor can determine whether or not you have an inability to absorb vitamin B-12 from natural food items.

USDA’s Recommendations for Vitamin B-12

The recommended dietary allowances (RDAs) are 2.4 micrograms daily for adults and adolescents aged 14 years and older, 2.6 micrograms daily for adult and adolescent pregnant females, and 2.8 micrograms daily for adult and adolescent lactating females. Because 10-30% of older people do not absorb food-bound vitamin B12 efficiently, those over 50 years of age should meet the RDA by eating foods fortified with B12, or by taking a B12 supplement. Supplementation of 25-100 micrograms daily has been used to maintain vitamin B12 levels in older people. A doctor and pharmacist should be consulted for use in these higher applications.

Ultimately, if you’re looking to lose weight avoid the quick fix solutions. If there was a wonder drug out there that magically helped shed extra pounds, everyone would be at a healthy weight.
