Yes, Jevity is Formulated for Lactose Intolerance
For many patients, the answer to "Is Jevity lactose-free?" is a reassuring yes, meaning it is suitable for those with lactose intolerance. This is because the manufacturing process removes the milk sugar, lactose, which is what causes digestive issues for lactose-intolerant individuals. This makes Jevity a safe and digestible option for tube-fed or orally supplemented patients who lack the enzyme lactase needed to break down milk sugars. However, the crucial point to understand is that being lactose-free is not the same as being dairy-free, and Jevity contains milk protein ingredients.
The Critical Difference: Lactose Intolerance vs. Milk Allergy
Many people confuse lactose intolerance and milk allergies, but they are two very different conditions, each with distinct implications for diet. Jevity's formulation highlights this distinction perfectly.
- Lactose Intolerance: This is a digestive issue caused by a deficiency of the enzyme lactase, which is needed to digest the sugar lactose found in milk. Symptoms are typically gastrointestinal and include gas, bloating, and diarrhea. A lactose-free product like Jevity is processed to remove this sugar, making it tolerable for these individuals.
- Milk Protein Allergy: This is an immune system response to the proteins found in milk, most commonly casein and whey. An allergy can cause a range of symptoms, from mild reactions like hives and rashes to severe, life-threatening anaphylaxis. Because Jevity contains casein, it is unsafe for anyone with a milk protein allergy.
Jevity’s Milk-Derived Ingredients
To provide complete nutrition, Jevity uses milk-derived proteins known as caseinates. Caseinates are an excellent source of protein, but they come from milk. A common formula variation, Jevity 1.5 Cal, lists its protein sources clearly on its ingredient label as "Sodium Caseinate" and "Calcium Caseinate," followed by the allergen warning "Contains milk and soy ingredients".
Here are some of the key ingredients found in Jevity formulas:
- Water
- Corn Maltodextrin and Corn Syrup Solids
- Sodium Caseinate (milk protein)
- Calcium Caseinate (milk protein)
- Canola Oil
- Soy Protein Isolate
- Fructooligosaccharides (FOS) and dietary fiber
- Medium-Chain Triglycerides (MCT)
- Soy Lecithin
- Essential vitamins and minerals
Who Should Avoid Jevity?
While suitable for lactose intolerance, there are several groups of people for whom Jevity is not appropriate. It is vital to consult a healthcare provider to determine if Jevity is right for your specific dietary needs.
Contraindication for Galactosemia
One absolute contraindication for Jevity is galactosemia, a rare genetic disorder where the body cannot properly metabolize galactose. Since lactose is made up of glucose and galactose, individuals with galactosemia must avoid all products containing lactose, even trace amounts. Although Jevity is lactose-free, it is still not considered safe for those with galactosemia due to potential for trace galactose and other metabolic considerations. The manufacturer explicitly warns against its use in these cases.
Comparison of Milk Sensitivity Conditions
| Feature | Lactose Intolerance | Milk Protein Allergy | Galactosemia |
|---|---|---|---|
| Underlying Cause | Digestive issue (lack of lactase enzyme) | Immune system response to proteins (casein, whey) | Genetic metabolic disorder (inability to process galactose) |
| Body's Reaction | Gastrointestinal distress (bloating, gas, diarrhea) | Allergic reaction (hives, swelling, potentially anaphylaxis) | Accumulation of toxic galactose metabolites, damaging organs |
| Suitability for Jevity? | Yes, Jevity is suitable for lactose intolerance. | No, Jevity contains milk protein (casein) and is unsafe. | No, Jevity is contraindicated for galactosemia. |
| Dietary Requirement | Avoid lactose; some tolerance is possible. | Avoid all dairy completely, including milk proteins. | Avoid all sources of galactose entirely. |
Consulting a Healthcare Professional
Before using Jevity or any specialized nutritional product, a healthcare professional, such as a doctor or registered dietitian, must be consulted. They can help determine the appropriate formula based on a patient's full medical history, dietary needs, and any existing allergies or metabolic conditions. Do not make assumptions based solely on the "lactose-free" label if there are concerns about milk allergies or other sensitivities.
Conclusion
In summary, Jevity is considered lactose-free and is suitable for individuals with lactose intolerance because the milk sugar is removed during processing. However, it is fundamentally a milk-based product, containing casein, and is not dairy-free. This means Jevity is not safe for those with a milk protein allergy. The product is also explicitly contraindicated for patients with galactosemia. Always verify product ingredients with your healthcare provider to ensure it aligns with all dietary requirements before consumption. For the most current ingredient information, always refer to the official Abbott Nutrition product label or packaging.

The Difference Between Lactose and Casein Explained
Lactose is a sugar, while casein is a protein; both are found in milk. Lactose intolerance is a digestive issue, whereas a casein allergy is a potentially life-threatening immune response. In Jevity, the lactose sugar is removed, but the casein protein remains, making it safe for lactose-intolerant individuals but dangerous for those with a milk protein allergy.
