Vitamin B-12 injections for weight loss: Do they work?
Are vitamin B-12 injections helpful for weight loss?
Answer
from Katherine Zeratsky, R.D., L.D.
There's no evidence that vitamin B-12 in any form — including vitamin B-12 injections — enhances weight loss. One study published in 2005 suggested that people who took a number of different supplements, including vitamin B-12, gained weight more slowly over a 10-year period than did those who took no supplements. However, many factors must be considered when interpreting the study results, including the fact that people who take dietary supplements tend to be more health conscious — which may contribute to better weight management.
If you're hoping to lose weight, resist the lure of quick and easy solutions. What counts is a healthy lifestyle. Enjoy healthier foods and include physical activity in your daily routine.
