Our Multi-Complete 45 contains all of the vitamins and minerals that are in our original multivitamin formula PLUS 45 mg of iron daily. This product was developed for gastric bypass or sleeve gastrectomy patients who require a higher level of iron supplementation and would like to avoid taking a separate iron supplement. It is important to keep in mind that this product may NOT be taken at the same time as calcium to prevent absorption interference. Daily Dosage = 2 Capsules
