Though people in Western nations have been taking dietary supplements and multivitamins for years, researchers have only recently begun looking into the benefits of distributing such products in underdeveloped countries, like those in sub-Saharan Africa. However, a new meta-study indicates that a special powdered formula may help prevent anemia among underfed children worldwide.

Published in the Cochrane Systematic Review, the report describes using a special powdered mixture to feed children between 6 months and 2 years old. The formula contains zinc, iron and vitamin A, among other vital nutrients.

How did the authors come up with the mixture? They analyzed the findings of eight previous reports, which had been conducted among undernourished children in Asia, Africa and the Caribbean.

Adding such a nutrient powder to a child’s meals reduces his or her risk of anemia by one third, the review stated, adding that such supplementation also lowers the risk of iron deficiency by one half.

Among U.S. adults, vitamin supplements play an important role in delivering essential vitamins and minerals to those who need them.
