This is a therapeutic nutritional product, not a routine formula. It is typically prescribed for infants with hypercalcemia, including conditions such as Williams syndrome or idiopathic infantile hypercalcemia, where dietary calcium and vitamin D intake must be minimized. Because complete restriction of these nutrients carries its own risks, Calcilo XD is always used under the direction of a physician or metabolic dietitian, who determines the concentration, volume, and any supplementation appropriate for the child.

Parents and caregivers often ask how to prepare it: like most Abbott powdered formulas, Calcilo XD is reconstituted with water to the dilution your care team specifies. Follow the mixing instructions on the can and your clinician's guidance exactly — the calorie and nutrient balance depends on correct preparation. The added iron helps support healthy development during the critical first year.

Because managed-diet products are used continuously and can be difficult to source locally, we stock Calcilo XD by the can so families can maintain a reliable supply. For other Abbott metabolic and specialty nutrition options, you may also want to review Paramount XD. As with any medical food, keep your prescribing clinician informed of your child's feeding and growth.
