The term “Jevity formula” refers to a product line manufactured by Abbott Nutrition, a leading provider of medical foods. Contrary to a typical formula that follows a standard equation, Jevity is a brand name for a family of nutritional supplements formulated to provide complete and balanced nutrition for individuals who cannot consume enough nutrients orally. Primarily utilized for enteral (tube) feeding, these formulas contain a specific blend of carbohydrates, proteins, fats, dietary fiber, and essential vitamins and minerals tailored to various patient needs.
The Core Components of the Jevity Formula
A Blend of Macronutrients
At its core, every Jevity formula is composed of macronutrients designed to support overall health and weight maintenance. Protein is typically sourced from caseinates (milk-derived) and soy protein isolates, providing essential amino acids for tissue repair and lean body mass maintenance. The primary carbohydrate sources are corn maltodextrin and corn syrup solids, which supply readily available energy. Fats are included to provide concentrated energy and essential fatty acids, often from a blend of canola oil, corn oil, and medium-chain triglycerides (MCTs).
The Role of Fiber and Prebiotics
A key differentiating feature of Jevity is its fiber content, which includes a mix of soluble and insoluble fibers, along with fructo-oligosaccharides (FOS).
- Moderating Bowel Function: The blend of fiber helps to regulate bowel movements, which can be particularly important for tube-fed patients who may experience issues like constipation or diarrhea.
- Promoting Gut Health: The inclusion of FOS acts as a prebiotic, stimulating the growth of beneficial bacteria in the colon. This helps to support a healthy digestive tract and improves overall gastrointestinal function.
Vitamins and Minerals
To ensure complete nutritional support, Jevity formulas are fortified with a wide spectrum of essential vitamins and minerals. The specific composition and quantities meet or exceed the Recommended Dietary Intakes (RDIs) for a full day's nutrition, ensuring that patients receive the necessary micronutrients for their recovery and health. The vitamin and mineral content is carefully calibrated to the formula's caloric density to provide balanced nutrition.
Comparing Different Jevity Formulations
Abbott offers various Jevity formulas, each with a different caloric density to suit specific patient requirements. The number in the product name corresponds to its caloric density in calories per milliliter (Cal/mL).
| Feature | Jevity 1.2 Cal | Jevity 1.5 Cal | 
|---|---|---|
| Caloric Density | 1.2 Cal/mL | 1.5 Cal/mL | 
| Typical Use | Patients needing high protein and moderate calories, or those intolerant of hyperosmolar feedings. | Patients with fluid or volume restrictions who need more calories in a smaller serving. | 
| Protein Content | High protein (e.g., 18.5% of calories). | High protein (e.g., 17% of calories). | 
| Fiber Content | Fortified with a balanced fiber blend, including FOS. | Higher concentration of fiber and FOS compared to the 1.2 version. | 
Who Benefits from a Jevity Formula?
Healthcare professionals prescribe Jevity for a variety of conditions where patients cannot consume adequate nutrition on their own. These include:
- Long- or Short-Term Tube Feeding: For patients recovering from surgery, trauma, or illness that prevents oral intake.
- Supplemental or Sole-Source Nutrition: Used as a complete nutritional source when oral intake is impossible or supplemented with regular food for additional nutrients.
- Oral Feeding for Altered Taste Perception: Some formulas can be consumed orally by patients whose sense of taste is altered, often due to cancer treatment.
- Weight Management: The calorically dense formulas assist in helping patients gain or maintain a healthy weight.
- Bowel Management: The fiber content is particularly beneficial for patients prone to diarrhea or constipation, helping to normalize bowel function.
Administration and Precautions
Jevity formulas are typically ready-to-use liquids, available in containers designed for tube feeding, such as Ready-to-Hang bottles, as well as oral-friendly cartons. It is crucial to use Jevity under medical supervision, as a healthcare provider will determine the appropriate formula, flow rate, and volume for a patient's specific needs.
Common side effects associated with enteral feeding, including the use of Jevity, can include nausea, diarrhea, constipation, bloating, and cramping. A healthcare team, including a registered dietitian, can help manage these side effects by adjusting the feeding schedule or formula. It is essential to note that Jevity is not for intravenous (IV) use and should not be used by individuals with galactosemia, a rare genetic disorder. All medical foods require careful handling to prevent contamination, and proper preparation instructions must be followed. Abbott Nutrition provides detailed information on their Jevity products.
Conclusion
In conclusion, the Jevity formula is not a generic term but a specific line of fiber-fortified, complete, and balanced nutritional products from Abbott. The different formulations, such as Jevity 1.2 and 1.5, cater to various caloric and protein requirements for patients needing enteral or supplemental nutrition. Due to its specialized nature, its use should always be guided by a physician or qualified healthcare professional to ensure safe and effective nutritional support.
