XMet Maxamum Preparation

Maxamum must be consumed in conjunction with natural protein, fluid and other nutrients in quantities prescribed by a dietitian or physician to meet protein and general nutrition requirements. Fat, carbohydrate and low protein sources may be used to supply needed calories and to fulfill essential fatty acid requirements.

Maxamum intake will vary depending on the age, body weight and medical condition of the individual. Intake is adjusted to maintain normal growth and development.

Maxamum is best served as a chilled drink with meals. Make a paste of the prescribed amount of powder with a small volume of water. For accuracy, Maxamum should be weighed on a gram scale. Gradually add sufficient water to yield the prescribed volume. It is recommended that Maxamum initially be reconstituted at a 1 to 7 dilution (e.g. 100 g of Maxamum and 700 mL of water). It can however be given in a more concentrated form (e.g. at a 1 to 5 dilution or in paste form), according to taste preferences. Additional fluids should then be offered at the same time.
Reconstituted formula should be stored in the refrigerator and used within 24 hours.
