Understanding ProSource Product Variations
ProSource is not a single product but a brand offering several protein supplements designed for different dietary needs, often under medical supervision. This variety means that the calories and protein content differ based on the specific formulation. The most common types include liquid supplements, powdered proteins, and specialized formulas like those for tube feeding or low-carb diets. Because ProSource is primarily used in clinical settings, such as for individuals with malnutrition, wound healing needs, or renal disease, it's essential to check the specific product label for accurate information.
ProSource Liquid Protein Formulas
Liquid ProSource supplements are highly concentrated and are a popular choice for their low volume and high nutrient density. These are often consumed as a 'protein shot' or added to other foods and beverages.
- ProSource Plus Liquid Protein: A standard 30mL serving typically contains 100 calories and 15 grams of protein. It is formulated with a blend of hydrolyzed collagen and whey protein isolate to provide a complete amino acid profile. This formula is suitable for a wide range of patients and is lactose and gluten-free.
- ProSource Liquid (Original): An earlier version of the liquid supplement offers 100 kcal and 10 grams of protein in a 30ml sachet, using a blend of collagen hydrolysate and whey protein isolate.
- ProSource NoCarb Liquid Protein: For those on carbohydrate-restricted diets, a 30ml serving of this variant provides 15 grams of protein with 0 grams of carbohydrates, resulting in fewer calories than the 'Plus' version. This makes it an ideal option for specific medical conditions.
ProSource Powdered Protein
Unlike the pre-measured liquid forms, ProSource also offers a powdered supplement for greater mixing versatility.
- ProSource Protein Supplement Powder: A typical serving of this dual-action powder provides 6 grams of protein. It combines fast-acting whey protein and slow-digesting casein protein to support muscle repair and enhancement. It is unflavored and can be mixed into hot or cold foods and drinks without clumping. Since the powder contains minimal carbohydrates and fats, the calorie count per 6-gram serving would be approximately 24 calories, based on the standard 4 calories per gram of protein.
Specialized ProSource Formulas
For specific medical applications, specialized formulas are available.
- ProSource TF (Tube Feeding): This formula is designed for enteral feeding and contains 11 grams of protein and approximately 44 calories per 45ml serving. It has a water-like consistency to prevent tube blockage and is lactose and gluten-free.
- ProSource Jelly: A dessert-like option used in clinical settings, each 118ml serving provides 20 grams of protein and only 90 calories, making it a protein-rich, low-calorie choice.
How to Calculate Nutritional Values
To calculate the calories from protein in any ProSource product, use the conversion factor of 4 calories per gram of protein. For example, a product with 15 grams of protein from collagen and whey isolate contributes $15 imes 4 = 60$ calories from protein. The remaining calories would come from other macronutrients, such as carbohydrates and fat.
Example calculation: ProSource Plus Liquid Protein
- Nutritional content (per 30ml): 15g Protein, 11g Carbohydrates, 0g Fat.
- Calories from Protein: $15 imes 4 = 60$ calories.
- Calories from Carbohydrates: $11 imes 4 = 44$ calories.
- Total Calories: $60 + 44 = 104$ calories (rounding may cause slight variation from listed 100 kcal).
Comparison of ProSource Products

| NoCarb Liquid Protein | 30ml | 15g | <75 | No carbohydrates | Renal dialysis, carb-restricted diets | Lower calorie count |
| TF (Tube Feeding) | 45ml | 11g | 44 | Low volume, water-like consistency | ICU/tube-fed patients | Prevents tube blockage |
| Jelly | 118ml | 20g | 90 | Gelatinous dessert | Post-op bariatric, elderly | Palatable, low volume |
Conclusion: Choosing the Right ProSource Product
The nutritional profile of ProSource varies greatly depending on the product, underscoring the importance of checking the specific formula's label. From the high-protein, compact liquid 'shots' to the versatile powdered versions, each is designed to meet specific nutritional and medical requirements. For individuals needing a rapid protein and calorie boost, the concentrated liquid forms like ProSource Plus are effective. For those with carbohydrate restrictions or other specialized needs, variants like ProSource NoCarb or TF are more appropriate. The powdered protein offers flexibility, while the jelly provides an alternative for specific patient groups. Always consult a healthcare professional, especially when using these products for medical purposes, to ensure the correct formulation is chosen for your dietary needs. For general wellness or workout recovery, the specific nutritional goals should guide the product selection.
