Terms to know>>

• Chelated: Chelated minerals are attached to amino acids that facilitate absorption by the body. Taking minerals with food can have a similar effect, but if you have trouble absorbing minerals, chelated forms are more consistent, reliable sources.
• Natural: Typically, natural supplements don't contain artificial colors, flavors, sweeteners, or preservatives.
• Whole foods: Nutrients have been extracted from natural, unprocessed food, and not made up in the chemistry lab. According to Jennifer Nevels, NMD, "whole-foods" vitamins can be less potent than synthetic supplements, but the body may absorb them more easily. If you choose a whole-foods vitamin, go organic to avoid ingesting concentrated amounts of pesticides and other harmful chemicals.
