When a person is considering taking a nutritional supplement, it is important for them to recognize the nutrients their body needs most and what various vitamins and minerals do. This may help them select the right product, experts say.

"Vitamins play a key role in building a healthy body from the inside out," said pharmacist Lauren Fallieras. "It is important to get these nutrients from a well-balanced diet, but it's not uncommon to fall short on select vitamins and minerals without even knowing it."

She said that it is important for individuals to educate themselves on the role each vitamin and mineral plays in the different aspects of their health. This will help them get a better idea of whether they would benefit most from a multivitamin or a more specific supplement, like vitamin D or calcium.

With this knowledge it may be possible for individuals to maintain balanced nutrition and support various areas of their health. Fallieras said that talking to a healthcare provider can help individuals learn exactly what their body needs and how to go about getting it, whether it be through diet or supplementation.
