Our Multi-Complete 45 contains all of the vitamins and minerals that are in our original multivitamin formula PLUS 45 mg of iron daily and an increased level of vitamin B-12 (1,000 mcg 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 Tablets
