Core Macronutrient Ingredients in Isosource 1.5 Cal
Isosource 1.5 Cal is a calorically dense, nutritionally complete formula designed for individuals who require supplemental or sole-source nutrition via oral or tube feeding. The foundational ingredients can be broken down into the primary macronutrient categories: protein, carbohydrates, and fats. The specific formulation can vary slightly depending on the regional product version (e.g., with or without fiber).
Protein Sources
The protein in Isosource 1.5 Cal is a high-quality blend of milk and soy proteins. This combination provides a complete amino acid profile to support lean body mass and other metabolic functions. Key protein ingredients often include:
- Milk protein concentrate: A dairy-derived source of protein.
- Soy protein isolate: A highly purified, plant-based protein.
- Sodium and calcium caseinates: Milk proteins that help provide a complete protein source.
Carbohydrate Sources
For energy, Isosource 1.5 Cal relies on a mix of easily digestible carbohydrates. These ensure a steady energy release, which is important for individuals who are ill or recovering. The main carbohydrate ingredients are:
- Corn syrup and maltodextrin: Easily absorbed carbohydrate sources that provide energy without excessive volume.
- Sucrose: Included in some versions for flavor and an additional energy source.
Fat Sources
The formula's fat content is strategically composed to aid absorption and provide essential fatty acids. A key feature is the inclusion of Medium Chain Triglycerides (MCTs), which are easily digested and absorbed directly into the bloodstream. Notable fat ingredients are:
- Canola oil: The primary fat source, rich in monounsaturated fats and the omega-3 fatty acid ALA.
- Medium chain triglycerides (MCTs): Derived from coconut and/or palm kernel oil, they enhance lipid absorption, especially for patients with malabsorption issues.
- Other vegetable oils: Some formulations may include sunflower or rapeseed oil.
Vitamins, Minerals, and Fiber
Isosource 1.5 Cal is formulated to be nutritionally complete, meaning it contains a wide array of vitamins and minerals to meet or exceed daily requirements when consumed in sufficient quantities. It also features a blend of fibers to support digestive health and bowel function.
Vitamin and Mineral Fortification
The formula contains a comprehensive vitamin and mineral blend to support overall health. Examples of these ingredients include:
- Vitamins: Vitamin A (palmitate and beta-carotene), Vitamin C (sodium ascorbate), Vitamin D3 (cholecalciferol), Vitamin E (dl-alpha-tocopheryl acetate), Vitamin K1, B vitamins (Thiamine, Riboflavin, Niacin, B6, B12), Folic Acid, Biotin, and Pantothenic Acid.
- Minerals: Potassium, calcium, sodium, magnesium, iron (ferrous sulfate), zinc, manganese, copper, iodine, selenium, molybdenum, and chromium.
Fiber Content
For products containing fiber, a blend of soluble and insoluble fibers is included to support digestive regularity.
- Soluble fiber: Ingredients such as fructooligosaccharides (FOS) and inulin are present to help with digestive health.
- Insoluble fiber: Pea fiber is commonly used to aid normal bowel function.
- Acacia gum: Another source of soluble fiber found in some versions.
Additives and Other Ingredients
Beyond the core nutrients, Isosource 1.5 Cal also includes several additives to maintain its consistency, palatability, and nutritional stability. These are present in small quantities but are essential for the product's function.
- Water: The primary solvent for all ingredients.
- Emulsifiers: Soy lecithin and other emulsifiers help keep the fat and water-based components mixed evenly.
- Stabilizers: Carrageenan and other stabilizers prevent the formula from separating.
- Amino Acid Derivatives: L-carnitine and taurine are included, which play roles in metabolic processes.
- Flavoring: Vanilla flavor is added to certain formulations to improve oral palatability.
Comparison of Isosource 1.5 Cal and Isosource Fibre 1.5
There are several versions of Isosource formulas, and the ingredient lists can differ. Here is a comparison focusing on the presence of fiber, a common point of variation.
| Feature | Isosource 1.5 Cal (standard) | Isosource Fibre 1.5 | Notes |
|---|---|---|---|
| Fiber Content | Some formulas do not contain fiber | Contains a blend of soluble and insoluble fibers, typically 15-16 g per 1000 mL. | The presence of fiber is a key distinction. |
| Macronutrient Profile | Provides calories from protein, carbs, and fats. | Similar to the standard version but with added fiber contributing to the carbohydrate content. | Both are calorically dense at 1.5 kcal/mL. |
| Digestive Health Support | Provides complete nutrition without specific fiber benefits. | Includes a fiber blend (pea, FOS, inulin) to support normal bowel function and digestive health. | The fiber version is better for patients needing bowel management. |
| Low Residue Status | Often considered a low-residue diet. | Not a low-residue diet due to its fiber content. | Important consideration for certain medical conditions. |
Conclusion
The ingredients in Isosource 1.5 Cal are carefully selected to provide a complete and calorically dense nutritional solution. The formula's base includes a robust combination of milk and soy proteins, energy-supplying carbohydrates from corn syrup and maltodextrin, and a fat blend featuring easy-to-absorb MCTs and heart-healthy canola oil. Fortified with a full spectrum of essential vitamins, minerals, and often a beneficial fiber blend, Isosource 1.5 Cal serves as a critical nutritional tool for patients with high energy demands, fluid restrictions, or other conditions requiring complete nutritional support. However, due to slight variations between product versions, especially concerning fiber content, it is crucial for healthcare professionals and users to always check the specific product label. Important: Isosource 1.5 Cal is for use under medical supervision and is not for parenteral (intravenous) use.
