4 min read

Jevity is a fiber-fortified nutritional formula used under medical supervision for patients who cannot meet their needs through normal eating. By delivering a comprehensive blend of macronutrients, vitamins, and minerals, Jevity works to support overall health, aid in weight maintenance or gain, and promote healthy bowel function.

Quick Summary

Jevity functions by supplying essential calories, protein, fiber, vitamins, and minerals via a feeding tube or oral supplementation. It features a unique fiber blend with prebiotics to support gastrointestinal health and moderate bowel function, which is critical for patients requiring sole-source nutrition.

Key Points

Complete Nutrition: Jevity provides a balanced mix of calories, protein, and fat for patients unable to meet their nutritional needs orally.
Fiber and Prebiotics: It contains a unique fiber and scFOS blend that regulates bowel function and stimulates beneficial gut bacteria, promoting digestive health.
Fortified Micronutrients: The formula is enriched with a wide range of essential vitamins and minerals to prevent deficiencies and support overall health.
High Caloric Density: Some versions offer concentrated calories, helping patients with fluid restrictions gain or maintain weight in a smaller volume.
Supports Recovery: Jevity aids in recovery for patients post-surgery, with malnutrition, or those suffering from chronic illnesses.
Dual Administration: It can be administered via a feeding tube for sole-source nutrition or used as an oral supplement for those with altered taste perception.

The Foundation of Jevity: Complete and Balanced Macronutrients

At its core, Jevity is formulated to deliver a complete nutritional profile, providing all the essential macronutrients needed for bodily function. This carefully balanced composition ensures that patients who are unable to eat, or have increased nutritional needs, receive the calories, protein, and fat required for energy, tissue repair, and overall health.

Proteins: Jevity typically utilizes a blend of high-quality milk and soy proteins (caseinates and soy protein isolates). These proteins are essential for building and repairing lean body tissue, supporting immune function, and aiding in recovery. The inclusion of multiple protein sources ensures a complete amino acid profile.
Carbohydrates: The primary energy source in Jevity comes from corn maltodextrin and corn syrup solids. This carbohydrate blend provides a steady release of energy, preventing rapid fluctuations in blood sugar levels. This is particularly beneficial for tube-fed patients who require a consistent caloric supply.
Fats: The fat component is derived from a mix of canola oil, corn oil, and medium-chain triglycerides (MCT). This combination of long-chain and medium-chain fatty acids offers a balanced energy source. MCTs are particularly useful as they are easily absorbed and metabolized, providing a readily available source of energy for the body.

The Role of Dietary Fiber and Prebiotics in Jevity

One of the key differentiators of Jevity from many other nutritional formulas is its inclusion of a unique blend of dietary fiber and fructooligosaccharides (FOS), a type of prebiotic. This fiber blend is crucial for supporting gastrointestinal health and promoting regular bowel function, which can be a significant issue for patients on long-term enteral nutrition.

Jevity's fiber blend works in several ways:

Moderates Bowel Function: The combination of soluble and insoluble fibers helps to regulate stool consistency, addressing common issues like diarrhea and constipation.
Supports Beneficial Bacteria: The addition of prebiotics like scFOS (short-chain fructooligosaccharides) provides nourishment for the beneficial bacteria in the colon. This helps maintain a healthy gut microbiome, which is vital for digestive and immune health.
Promotes Overall Gut Health: By modulating the gut environment, Jevity's fiber blend reduces the risk of gastrointestinal complications often associated with tube feeding, leading to better patient tolerance and comfort.

The Micronutrient and Nutrient Fortification Process

In addition to its macronutrient profile, Jevity is heavily fortified with a wide array of vitamins, minerals, and conditionally essential nutrients. This fortification ensures that patients receive 100% of the recommended daily intake for a comprehensive list of micronutrients, preventing deficiencies.

These micronutrients are essential for:

Supporting Immune Function: Vitamins A, C, and E, along with zinc and selenium, play crucial roles in maintaining a healthy immune system, aiding the body's ability to fight off infections.
Metabolic Processes: B vitamins are vital cofactors in countless metabolic reactions, including energy production.
Muscle Maintenance and Repair: Minerals like calcium, phosphorus, and magnesium are critical for bone health, while antioxidants protect against cellular damage.
Cellular Function: Nutrients such as L-carnitine and taurine are included to support various cellular functions and overall patient wellness.

Jevity vs. Standard Formulas: A Comparison

To understand how Jevity works effectively, it's helpful to compare it to a standard, non-fiber-fortified formula, like Ensure (in its basic form). While both are complete nutritional formulas, their composition and target applications differ significantly.


Feature	Jevity (Fiber-Enriched)	Standard Formula (e.g., Basic Ensure)
Primary Feature	Fiber-fortified with prebiotics.	Typically fiber-free or low-residue.
Target Patient	Patients needing GI support, or prone to diarrhea/constipation.	General tube-feeding patients, or those requiring low-residue diets.
Gastrointestinal Effects	Promotes regular bowel function and beneficial gut bacteria.	Minimal GI effects, but can lead to bowel irregularities over time.
Macronutrient Profile	Balanced calories, protein, and fat.	Similar macronutrient balance, but without added fiber.
Purpose	Addresses GI issues while providing complete nutrition.	Provides general complete nutrition when fiber is not needed.

The Mechanism of Action and Clinical Applications

Jevity's mechanism of action is multifaceted. The formula is designed to be easily administered via a feeding tube (or orally for some patients). Once delivered, the macronutrients are absorbed to provide energy and building blocks for the body. The fiber and prebiotics move into the colon, where they are fermented by gut bacteria. This fermentation process produces beneficial short-chain fatty acids (SCFAs), which provide energy for colonocytes and contribute to overall gut health.

Clinically, Jevity is used for a variety of conditions, including:

Malnutrition: For patients who are malnourished or at risk of becoming so, Jevity provides a dependable source of complete nutrition.
Fluid Restrictions: Calorically dense versions like Jevity 1.5 cal can provide high energy in a smaller volume, benefiting patients with fluid restrictions.
Post-Surgery Recovery: Provides essential nutrients needed for healing and recovery.
Altered Taste Perception: Can be used orally for patients whose perception of taste is altered, making it difficult to consume regular food.

Conclusion

Jevity functions as a comprehensive nutritional support system, distinguished by its unique fiber and prebiotic blend that actively supports gastrointestinal health. Beyond just supplying calories, protein, and fat, the formula addresses specific patient needs related to bowel function, helping to moderate issues like diarrhea and constipation. By combining complete macronutrient delivery with a fortified vitamin and mineral profile, Jevity ensures that tube-fed patients and those with altered dietary needs receive balanced, well-tolerated, and effective nutritional therapy. This mechanism of action provides a dual benefit: meeting immediate caloric requirements while also nurturing long-term gut health, making it a reliable option in clinical nutrition.
