One of the main sources of minerals and vitamins are vegetables and fruits. They have a great importance in helping the body to finish some of its necessary functions, and are usually found in a multivitamin.
The most important thing is to recognize the signs of nutritional deficiency. You can consume individual vitamin, a multivitamin or mineral but only with advice or permission by nutritionist. Do not take them on your own because it could cause an imbalance or even overdose.
