However, tolerability of supplements could be a limitation, and their universal use is not supported by the heterogeneity of previous studies, especially in patients without malnutrition. <jats:italic>Methods:<\/jats:italic> This study is a randomized, controlled, open, parallel, 3\u2010arm clinical trial comparing supplementation with protein powder dissolved in liquids to aim at 36 g of protein per day, energy and protein supplements to aim at 37.6 g of protein and 500 kcal per day, or no intervention in normally nourished or mildly undernourished patients. Outcomes were serum albumin, prealbumin, retinol\u2010binding globulin, and body mass index, among others. Postoperative complications were also recorded. <jats:italic>Results:<\/jats:italic> Ninety patients aged 83.8\u00b1 6.6 years were included. The mean ingested amount of supplements was 41.1% \u00b1 20.6% in the protein powder supplement group and 51.4% \u00b1 13.2% in the energy protein supplement group (<jats:italic>t<\/jats:italic> = 2.278, <jats:italic>P<\/jats:italic> = .027). Postoperative supplements had no effect on the nutrition status during in\u2010hospital follow\u2010up, as assessed by serum albumin (<jats:italic>P<\/jats:italic> = .251), prealbumin (<jats:italic>P<\/jats:italic> = .530), retinol\u2010binding globulin (<jats:italic>P<\/jats:italic> = .552), or body mass index (<jats:italic>P<\/jats:italic> = .582). Multivariate analysis showed that length of hospital stay with an established complication until its resolution (\u03b2 = .230, <jats:italic>P<\/jats:italic> = .031), total hospital stay (\u03b2 = .450, <jats:italic>P<\/jats:italic> &lt; .001), baseline body mass index (\u03b2 = .204, <jats:italic>P<\/jats:italic> = .045), and total daily ingested proteins per body weight (\u03b2 = .252, <jats:italic>P<\/jats:italic> = .018) were predictive variables on the change in serum albumin (<jats:italic>R<\/jats:italic> <jats:sup>2<\/jats:sup> = 0.409, <jats:italic>F<\/jats:italic> = 11.246, <jats:italic>P<\/jats:italic> &lt;
