Boost Optimum (fka Isocal) Reviews of Nutrient Information

Some elderly or patients suffering from disease, trauma, or premature birth may be unable to consume food orally. Some examples may be burn victims, cancer patients, or other chronic illness victims. In such cases, they have to depend on tube feeding (also known as enternal nutrition) to deliver adequate calories and nutrients. Boost Isocal is a specially formulated nutrient solution to use in either tube-feeding or oral consumption to meet a person’s nutrient and energy needs.  



Boost Optimum Isocal Liquid can be consumed by mouth or tube.

Do note that Boost Optimum liquid or the isocal powder (mixed with water) can be taken as an oral supplementation. Nutritionists may though suggest Ensure Life, Ensure Plus, etc as a more common milk feed. Boost Optimum Isocal Liquid is recommended for those with lactose intolerance or to avoid diarrhoea problems associated with lactose. It is also recommended as an isotonic feeding to avoid problems associated with diets of high osmolar concentrations.  Hence many caretakers tend to have Isocal products for tube feeding purposes. It also contains MCT oil which facilitates digestion and absorption of fats. 100% of United States’ RDA (Recommended Dietary Allowances) are fulfilled in 2000 kcals of Boost Optimum Isocal.

Nutrient Information

Boost Optimum liquid or Boost Optimum powder is a lactose-free, isotonic formula. There are 1,060 calories in a single serving size of 1,000 ml. It is designed as overall, complete tube-feeding formulas that are high in carbohydrates, protein, fats, and vital nutrients and minerals for a person’s daily nutritional requirements. A single serving of 1,000 ml contains 45 % daily value of carbohydrates and 68 % daily value of protein and fat. It contains more than the recommended daily value of vitamin C,  B-12, B-6, E, riboflavin, niacin, and pantothenic acid and is adequate in a variety of other nutrients and minerals.

Preparation and Administration of Boost Isocal Liquid by Nestle

Boost Optimum Isocal liquid comes as a Ready-To-Drink or ready-to-use formula that requires no mixing or preparation before feeding. Boost Optimum powder would require mixing with water prior to use. For oral consumption, just drink like any milk drinks. For tube feeding, caretakers should check that the tube is clean. It should be administered at room temperature as a slow, continuous drip according to the rate per hour prescribed by a physician. Caretakers must note to adjust the rate to ease unwanted side effects or according to the comfort level of the patients. Caretakers can either use a bag filled with the formula and hanging above the patient, to allow the formulate to drip slowly through the feeding tube via “gravity feeding”, or he/she can use a pump that controls the rate of delivery. Once feeding is complete, regular flushing of the tube is recommended to prevent clogging and to keep the tube clean.

Side Effects and how to adjust

Tube feeding may have unpleasant side effects of diarrhea, constipation or nausea and vomiting. This is especially so when a patient first start tube feeding as his/her body adjusts to the formula. Boost (Isocal) is designed without milk (lactose) to reduce the occurrence of diarrhea or side effects for those who are lactose intolerant. It is isotonic to avoid problems associated with diets of high osmolar concentrations.


If not opened, Boost Optimum liquid need not be refrigerated. Boost Liquid and Boost Optimum Powder should be kept in a dry, cool place away from direct sunlight. Once opened or mixed, Boost solutions should be kept refrigerated. At room temperature, it should be used within 6 or 8 hours. Do provide ample water to prevent dehydration, side effects, and other complications. To prevent aspiration, conduct the feeding with an individual sitting up at an angle of at least 30 degrees and this should continue 30 to 60 minutes after feedings.
