Introduction to Elemental Formulas
Elemental formulas, like those in the Vivonex line, are designed for individuals with severely compromised digestive systems. They provide nutrients in their simplest, most easily absorbed form, namely free amino acids rather than complex proteins. This minimizes the work required by the digestive system, allowing patients with conditions like pancreatitis, extensive bowel resection, or intestinal failure to receive essential nutrition. While they share many similarities, the difference between Vivonex Plus and Ten is significant for clinical applications and patient tolerance.
Key Differences: Vivonex Plus vs. Ten
The primary distinction between Vivonex Plus and Vivonex T.E.N. is the fat content, which directly influences their suitability for different patient conditions. Both are powdered, unflavored, and can be used for either oral supplementation or tube feeding. They provide 1.0 kcal/mL when reconstituted and are designed for use under medical supervision.
Comparison of Fat Content
- Vivonex T.E.N.: This formula is characterized by a very low fat content, with approximately 3% of total calories derived from fat. This minimal fat load is ideal for patients with severe fat malabsorption or those requiring reduced pancreatic stimulation, as in cases of acute pancreatitis. In a standard 80.4g packet, Vivonex T.E.N. contains just 0.8 grams of fat. The fat source is safflower oil.
- Vivonex Plus: This version contains a slightly higher fat level, with about 6% of total calories coming from fat. This provides a more balanced profile while still being considered a low-fat diet suitable for many GI conditions. A standard 79.5g packet of Vivonex Plus contains 2.0 grams of fat, sourced from soybean oil.
Clinical and Nutritional Differences
The variation in fat content leads to different clinical indications and nutritional compositions, which are vital for a medical team to consider.
Nutritional Breakdown
Beyond fat, the formulas have slightly different macronutrient profiles:
- Vivonex T.E.N.: Provides approximately 15% of its calories from protein, 82% from carbohydrates, and 3% from fat. It is enriched with glutamine, a key amino acid for gut health.
- Vivonex Plus: Offers a higher protein equivalent at 18%, 76% from carbohydrates, and 6% from fat. It also contains glutamine, arginine, and branched-chain amino acids, which are beneficial for stressed, catabolic patients.
Indications for Use
While both formulas are used for severely impaired GI function, specific conditions may be better managed by one over the other:
Vivonex T.E.N. is best suited for:
- Acute Pancreatitis
- Chylothorax (a condition with leakage of lymphatic fluid)
- Severe fat malabsorption
- Pre-surgical bowel preparation
Vivonex Plus is often indicated for:
- Extensive bowel resection
- Malabsorption syndrome
- Transitional feeding from TPN
- Severely impaired GI function requiring a modest amount of fat
Comparison Table
| Feature | Vivonex T.E.N. | Vivonex Plus |
|---|---|---|
| Protein Source | 100% Free Amino Acids | 100% Free Amino Acids |
| Fat Content (per packet) | 0.8g (approx. 3% of kcal) | 2.0g (approx. 6% of kcal) |
| Primary Fat Source | Safflower oil | Soybean oil |
| Key Benefit | Extremely low fat for severe malabsorption or pancreatic sensitivity | Lower fat formula for compromised GI function |
| Clinical Uses | Pancreatitis, chylothorax, short gut | Extensive bowel resection, malabsorption syndrome |
| Caloric Density | 1.0 Cal/mL | 1.0 Cal/mL |
Choosing the Right Formula
Because of the delicate nature of severe gastrointestinal disorders, the selection between Vivonex Plus and T.E.N. should always be made in consultation with a healthcare professional. The decision hinges on the specific clinical picture, including the patient's capacity for fat digestion and tolerance. While T.E.N. offers minimal fat for the most sensitive systems, Plus provides a slightly more comprehensive nutritional profile while remaining low in fat. The enriched amino acid profile, including glutamine, in both formulas helps support gut health and aid recovery.

Conclusion
While both Vivonex Plus and Vivonex T.E.N. are nutritionally complete, elemental formulas based on 100% free amino acids, their primary differentiating factor is the level of fat content. Vivonex T.E.N. is the more restrictive, very low-fat option, designed for the most severely compromised patients with issues like pancreatitis or severe fat malabsorption. In contrast, Vivonex Plus provides a slightly higher but still low fat level, making it suitable for a broader range of GI issues where some fat tolerance is present. Ultimately, the choice depends on a careful clinical assessment of the patient's digestive capabilities and nutritional requirements, guided by medical expertise.
