Preparation & Storage

Directions for Preparation and Use
Maxamaid must be consumed in conjunction with natural protein, fluid and other nutrients in quantities prescribed by a physician or dietitian to meet protein and general nutrient requirements.

The recommended intake of Maxamaid will vary depending on the age, bodyweight and medical condition of the individual. Intake should be adjusted to maintain normal growth and development. For accuracy, Maxamaid should be weighed on a gram scale. The daily intake of Maxamaid should be divided into equal portions and distributed throughout the day.

Maxamaid is best served with meals. Make a paste of the prescribed amount of powder with a small volume of chilled water. Gradually add sufficient water to make the desired volume. It is recommended that Maxamaid be prepared at a 1 to 7 dilution (e.g. 35 g (approx 1/4 cup) of powder plus 245 mL (approx. 8 fl oz) of water) and advanced to a 1 to 5 dilution (e.g. 35 g (approx 1/4 cup) of powder plus 175 mL (approx. 6 fl oz) of water). These dilutions are guidelines only. Maxamaid may be given in a more concentrated form (e.g. drink or paste). If so, water or diluted drinks should be offered at the same time. For best taste, consume immediately. Larger volumes of prepared drink mix should be refrigerated and used within 24 hours or preparation.
