During seasonal changes, the body consumes more vitamins and minerals that need to be replenished with adequate amounts of fruits and vegetables in the diet in conjunction with multivitamin dietary supplements . ESI created Multicomplex, a line of multivitamins and multiminerals that are ideally taken in warmer months when the body needs more liquids, and in colder months when vitamins are needed to protect the body from seasonal illnesses and in periods of physical and mental stress. Multicomplex is available in three formulas, each suitable for the different needs of adults, children, seniors and athletes. However, if you suffer from an Iron deficiency , ESI offers Ferrolin C : an Iron supplement with the addition of Vitamin C and Folic Acid to help aid the body’s ability to fully absorb the supplement’s beneficial properties. All of ESI’s multivitamin supplements are formulated to support high digestibility.
