The baby’s health depends on carefully following the instructions below. Use only as directed by a medical professional. Proper hygiene, preparation, dilution, use and storage are important when preparing infant formula. Powdered infant formulas are not sterile and should not be fed to premature infants or infants who might have immune problems unless directed and supervised by a doctor. Discuss with parents which formula is appropriate for the baby.
Discuss with parents whether they need to use cooled, boiled water for mixing and whether they need to boil clean utensils, bottles and nipples in water before use.
WARNING: Do not use a microwave oven to warm formula. Serious burns may result.
Refer to the product label for the most accurate information.
The baby’s medical professional will provide instructions for the correct amounts of water and powder. Pour the required amount of water into the bottle. Add the correct amount of powder, cap the bottle and shake vigorously.
If instructed to use the scoop in the can, each unpacked, level scoop delivers approximately 4.5 g of powder. Store DRY scoop in can.
Fat provides 47% of total calories in HCY 1. The fat content is similar to the fat content of human milk¶ and consists of a four-oil vegetable blend of palm olein oil (44%), soy oil (19.5%), coconut oil (19.5%), and high oleic sunflower oil (14.5%) along with ARA and DHA from single cell oils (2.5%). This fat blend provides a fatty acid profile similar to the fatty acid profile of breast milk¶.
¶ Comparison based on fatty acid profile of typical mature U.S. breast milk.
Protein equivalents provide 13% of total calories in HCY 1. The product provides the essential amino acids (except methionine) as well as nonessential amino acids (see Amino Acids table); 52% of the amino acids are essential amino acids. Since the product contains no methionine, care must be taken to provide enough methionine from breast milk, infant formula or other foods to support growth.
|Essential Amino Acids||Per 100 g Powder|
|Nonessential Amino Acids||Per 100 g Powder|
|Aspartic acid, mg||1300|
|Glutamic acid, mg||2600#|
# Added as glutamine.
Carbohydrate provides 40% of total calories in HCY 1. The carbohydrate blend is corn syrup solids, modified corn starch and sucrose (table sugar). The sugar in the product helps neutralize the taste of the amino acids. HCY 1 is suitable for someone with lactose intolerance.
Vitamins and Minerals
Vitamin and mineral levels in HCY 1 meet U.S. Food and Drug Administration requirements per 100 Calories for vitamins and minerals as mandated by the U.S. Infant Formula Act and the associated Code of Federal Regulations 21 C.F.R. part 107.1004. Amounts of B vitamins have been increased above levels in routine infant formulas for cofactor production. An increased level of choline, an essential nutrient important for brain development and the normal functioning of cells1-2, is provided. Calcium, iron, zinc, manganese, and copper levels are higher in order to help meet the needs for these minerals when low-protein solid foods are introduced.
