Abstract: Nutritional supplements which are especially useful for consumption (either orally or enterally) by glucose intolerant individuals. More specifically, sugar-free nutritional supplement formulations for glucose intolerant patients include docosahexaenoic acid (DHA), L-arginine, one or more edible fats and/or oils in an amount sufficient to provide between about 25 to about 60% of the total caloric value of the formulation, non-sugar carbohydrates in an amount sufficient to provide from about 2% to about 30% of the patient's daily energy requirements, proteins and/or amino acids in an amount sufficient to provide from about 5% to about 50% of the human's daily energy requirements, an artificial sweetener in an amount to impart a desired sweetness to the formulation, and a mineral and vitamin package containing minerals and vitamins in amounts sufficient to provide at least 10% of the recommended daily value (RDV) of each mineral and vitamin in the package.
