Core Components and Specialized Nutrients
Nutrison Advanced Peptisorb is a specialized, semi-elemental formula, meaning its components are broken down into smaller, easier-to-absorb molecules than standard feeds. The core of its formulation centers on highly digestible protein and fat sources, combined with a balanced blend of carbohydrates, vitamins, and minerals to provide complete nutrition for individuals who have difficulty with standard digestion.
Protein Source: Hydrolyzed Whey
The protein in Nutrison Advanced Peptisorb is derived from hydrolyzed whey protein, which is broken down into smaller peptide chains. This extensive hydrolysis is a defining feature, making the protein much easier to absorb in patients with compromised gut function. In fact, approximately 82% of the protein is composed of short-chain peptides, with the remaining 18% consisting of free amino acids to further optimize absorption. This composition minimizes the digestive effort required and reduces potential residue in the bowel, a significant advantage for those with intestinal disorders.
Fat Source: MCT and Soybean Oil
Unlike many standard enteral formulas that use long-chain triglycerides (LCTs), Nutrison Advanced Peptisorb incorporates a substantial amount of medium-chain triglycerides (MCT). MCTs are absorbed directly into the bloodstream from the intestinal tract, bypassing the lymphatic system that processes LCTs. This feature is particularly beneficial for patients with fat malabsorption due to conditions like pancreatitis or short bowel syndrome. The fat blend is comprised of both MCT oil (derived from coconut and palm oil) and soybean oil, providing both readily-absorbed energy and essential fatty acids.
Carbohydrate Source: Maltodextrin
The primary carbohydrate source is maltodextrin, a polysaccharide that is easily digestible and provides a balanced source of energy. The formula is also low in lactose, making it suitable for many individuals with lactose intolerance. The absence of added fibre ensures suitability for patients who require a residue-restricted diet.
Comprehensive Vitamin, Mineral, and Trace Element Profile
A full profile of essential vitamins and minerals is included to ensure complete nutrition when used as a sole source of nutrition. Key nutrients include:
- Vitamins: A, D, E, K, C, and a full range of B vitamins (Thiamin, Riboflavin, Niacin, Pantothenic acid, B6, B12, Folic acid, Biotin).
- Minerals and Electrolytes: Sodium, Potassium, Chloride, Calcium, Phosphorus, Magnesium, Iron, Zinc, Copper, Manganese, Fluoride, Molybdenum, Selenium, Chromium, and Iodine.
- Carotenoids: The formula is enriched with carotenoids (beta-carotene, lutein, lycopene), which are antioxidants that support overall health.
- Other Components: Choline, Taurine, and L-carnitine are also added for their nutritional benefits.
Comparison: Nutrison Advanced Peptisorb vs. Standard Enteral Formulas
| Feature | Nutrison Advanced Peptisorb | Standard Enteral Formula (e.g., Nutrison) | Rationale for Peptisorb |
|---|---|---|---|
| Protein Source | Extensively hydrolyzed whey protein, short-chain peptides and free amino acids. | Intact soy, pea, and whey proteins. | Predigested protein is easier to absorb in patients with impaired digestion/absorption. |
| Fat Source | 49% of fat from medium-chain triglycerides (MCT) and soybean oil. | Primarily long-chain triglycerides (rapeseed, sunflower, fish oil). | MCTs are absorbed directly, benefiting those with fat malabsorption. |
| Fiber Content | Fibre-free formula. | Can be with or without fiber; standard Nutrison is typically fibre-free. | Residue-restricted diet is necessary for many patients with GI impairment. |
| Digestion Effort | Minimal effort required due to semi-elemental nature. | Requires normal digestive function to break down larger molecules. | Reduces stress on a compromised digestive system. |
The Role of Key Additives
- Demineralized Water and Maltodextrin: These form the base of the formula, providing hydration and a primary source of carbohydrates for energy. Maltodextrin is a common and easily digestible carbohydrate source used in medical nutrition.
- Acidity Regulator (Citric Acid): Ensures the formula maintains a stable pH level.
- Vitamins and Minerals: The extensive list of micronutrients addresses the specific deficiencies that can arise from prolonged periods of poor digestion and absorption.
- Carotenoids (Beta-carotene, Lutein, Lycopene): These antioxidants help protect against cellular damage and support immune function, addressing potential deficiencies in critically ill patients.
- Taurine and Choline: These are conditionally essential nutrients that are vital for metabolic processes and cellular function, especially important for patients who are nutritionally stressed.
Conclusion
Nutrison Advanced Peptisorb's ingredient list is a testament to its specialized medical purpose. By utilizing extensively hydrolyzed whey protein and a high percentage of MCT oil, it effectively bypasses common digestive issues in patients with compromised gastrointestinal function. The inclusion of a complete vitamin and mineral profile, along with beneficial carotenoids, ensures that it can serve as a sole source of nutrition. This careful composition is what makes it a suitable and highly effective option for those with severe malabsorption or maldigestion, to be used under the strict supervision of a healthcare professional.
