B12 Shots: Pros & Cons

Vitamin B12, also known as cobalamin, is a water soluble vitamin vital for performing many body functions, including building DNA, supporting brain and nervous system function, and synthesizing fatty acids.  B12 plays a key role in energy, growth and appetite.  Most commonly, it is found in dairy and animal products. Since B12 naturally accelerates the rate of metabolism, it is becoming a big weight loss craze in the form of injectable shots. The following highlights some pros and cons of B12 shots:

Pros:

-Improved absorption via injection into the muscle and rapid release into the bloodstream (particularly useful for those with malabsorption problems)

-Boosts energy and metabolism, thus decreasing fat storage

-Retains nearly all the B12 vs. pill form

-Boosts mood & concentration by increasing levels of serotonin (especially helpful with depressed patients)

-Thins the blood to prevent stroke & maintain cardiovascular health

-Treats B12 deficiency & anemia and possibly effective for age-related macular degeneration

Cons:

*No scientific proof of weight loss effects

-Expensive: about $65 per shot plus sometimes ~$200 for an initial consultation with a physician)

-Helpful only to people with a B12 deficiency

-Should be supervised by a physician and is not advised for long term use

-Should NEVER replace a healthy diet

-Excess B12 is excreted in the urine (aka. a waste)

-Common side effects: mild diarrhea, nausea, pain at injection site, swelling sensation, headache, joint pain (rare cases: rapid heart rate, coughing, chest pain)

-Can interfere with the effectiveness of some medications (eg. Chloramphenicol might decrease the effects of B12 by decreasing new blood cells)

-Not advised for people with Leber's disease (hereditary eye disease) or sensitivity to cobalt or cobalamin

It is also important to note that people who opt for B12 shots are typically those already conscious about their weight or following a strict diet (such as a vegan or vegetarian diet); therefore, B12 will provide them with increased energy, allowing them to exercise more frequently and harder. The result? Weight loss.

The bottom line is that more research needs to be done in this area.  Although B12 injections are not likely to harm your health, the most important thing is to eat a healthy, balanced diet and include physical activity in your daily routine.  Before choosing expensive shots with possible side effects, try incorporating more foods that are rich in B12.  Resist the lure of quick and easy solutions, and work for your health.  You're worth it.
