  • The only extensively hydrolysed formula for infants to contain galacto- and fructo-oligosaccharides (GOS/FOS), which encourage the growth of friendly bacteria in the gut1-2 and have also been shown to reduce allergic manifestations over 5 years3.
  • The Aptamil Pepti range is the UK's most palatable EHF range4-5. Aptamil Pepti is whey-based and contains lactose for superior palatability, compared with a casein-based hydrolysate6.
  • Aptamil Pepti 2 is formulated with extra calcium, vitamin D and iron to meet the requirements of infants with cow's milk allergy. 

Q. How does Aptamil Pepti 2 help manage the symptoms of CMA?

A. An extensively hydrolysed formula (EHF) is usually recommended for mild or moderate cases of CMA. This is because the proteins have been broken down to make them easier to tolerate and digest. Aptamil Pepti 2 is an extensively hydrolysed whey-based formula containing 80–85% short chain peptides and 15–20% free amino acids.

Q. Why is Aptamil Pepti made with whey?

A. Aptamil Pepti is 100% whey-based to give it a more palatable taste.

Q. What age is Aptamil Pepti 2 suitable for?

A. Aptamil Pepti 2 is suitable from 6 months of age to complement a cow's milk free weaning diet.

Q. How long should a baby stay on Aptamil Pepti 2?

A. All babies are different. If an infant is still experiencing symptoms by 6 months of age, Aptamil Pepti 2 can be used. Most babies grow out of their allergy between 1 and 3 years old, particularly if they have delayed symptoms after ingesting cows’ milk. Others may take a bit longer.

Q. Is Aptamil Pepti 2 suitable for babies with other dietary requirements?

A. This product is not suitable for vegetarians as it contains LCPs sourced from fish.

Q. Is there anything unusual about the preparation of the formula?

A. Due to the specialist formulation, there may be some separation of prepared feeds on standing. It should be shaken well before use.

Q. How does Aptamil Pepti 2 differ from Aptamil Pepti 1?

A. Clinically, the products are the same. They have the same hydrolysate and all the evidence to support the clinical efficacy of Pepti 1 is applicable to Pepti 2. However, nutritionally, Pepti 2 has been specially formulated to provide the increased levels of key micronutrients, such as calcium and iron, required from 6 months. Increased levels of calcium are particularly relevant to infants who are on a dairy-free diet due to CMA, as the majority of an infant’s calcium intake usually comes from dairy. In addition, iron stores start to deplete between 4 and 6 months in infants, so a dietary source of iron is important.
