Peptamen® Junior


The Peptamen® Junior family of semi-elemental enteral and oral formulas offer complete nutritional support and improved feeding tolerance for patients with conditions such as malabsorption, diarrhoea, feeding intolerance to standard enteral formulas, delayed gastric emptying, short-bowel syndrome, and pancreatic insufficiency.

Whey-peptide formulas, such as Peptamen® Junior, have been shown to achieve improved outcomes for patients who are unable to digest or absorb standard enteral formulas.1

Peptamen® Junior Advance, Peptamen® Junior Liquid and Peptamen® Junior Powder are all supported by clinical evidence. The Peptamen® range is also the only family of 100% whey peptide formulas for the early years to adulthood.


Facilitates gastric emptying:

  • While casein-based feeds can precipitate in the stomach,2 whey-based formulas like Peptamen® Junior remain liquid
  • Peptamen® Junior, with its hydrolysed 100% whey protein and MCT content, significantly improves gastric emptying and reduces the frequency of vomiting vs. casein-based formulas3

Optimises absorption:

  • Whey-based feeds may help patients with difficulties digesting or absorbing standard diets to reach their nutritional goals and improve health outcomes1
  • Peptamen® Junior is made with 53–60% of fat as MCT, which may help improve digestion and absorption4
  • Peptamen® Junior has low to moderate osmolarity, which may help reduce the risk of osmotic diarrhoea5,6
  • In a 1-year prospective study, Peptamen® and a regular diet with oral nutritional supplements significantly increased height and weight velocity when compared to the previous year7
  • In a study of children with severe growth failure, Peptamen® (28 days, every 4 months) significantly increased bone density z-scores after 1 year vs. those fed a high-calorie diet only8
  • All products in the Peptamen® Junior range have pH levels between 6 and 79
  • SmartFlexTM – recyclable, collapsible, semi-rigid enteral bottle, utilising an advanced sterilisation process, offers improvements in safety and handling
