Osmolite Tube Feeding Formula

Osmolite is Abbott's isotonic, low-residue tube feeding formula for adults who need complete, balanced nutrition delivered through a feeding tube. Because it's isotonic, Osmolite is well tolerated by patients sensitive to formulas with a higher osmolality — a common concern for anyone managing long-term enteral feeding at home or in a facility. Every version is unflavored and nutritionally complete, meaning it can serve as a sole source of nutrition when prescribed.

The main decision when ordering is caloric density, and Osmolite comes in three strengths so you can match the formula to fluid needs and calorie goals. Osmolite 1.0 Cal (item 62691) provides standard calories with generous fluid, useful for well-hydrated patients or those needing higher volumes. Osmolite 1.2 Cal (62697, 62693, 64635) steps up the calories per milliliter — helpful when a patient needs more energy without a large increase in volume. Osmolite 1.5 Cal (62699, 64837) is the most concentrated, delivering the most calories in the least fluid, which suits patients on restricted volumes or those who tire during longer feeds.

Packaging matters as much as strength for daily use. Ready-to-Hang bottles and cartons (such as the 1000 mL and 1500 mL closed-system options) connect directly to a pump set, reducing handling and contamination risk during continuous or overnight feeding. The 8 oz. Ready-to-Use cartons (64635, 64837) are convenient for bolus or gravity feeding and easy to store, portion, and travel with.

Osmolite is a prescription-guided nutrition product, so confirm the caloric strength, volume, and feeding schedule with the ordering clinician or dietitian before switching formulas. Buying by the case keeps consistent stock on hand for patients on daily enteral support.
