Abstract: Background: Older adults are at a greater risk of developing sarcopenia due as a result of reduced mobility, malnutrition, dietary changes, and select diseases. Currently, there are no systematic reviews analyzing the effects of supplementation with leucine alone or as part of a supplement, either with physical exercise or without physical exercise in the elderly with sarcopenia. We aim to systematically review the evidence in intervention studies on the effect of supplementation with leucine, either alone, together with other supplements or together with other supplements and PE in the elderly with sarcopenia.  Materials and methods: Bibliographic searches related to the topic were conducted in three databases (Pubmed/Medline, Cochrane and SciELO) looking for articles published prior to December 2020. This review includes intervention studies in older adults over 60 year of age with a history of sarcopenia where researchers reported on the effect of leucine supplementation, with or without physical exercise, related to disease treatments or outcomes.  Results: The systematic review identified three intervention studies examining the effect of leucine without physical exercise, one of leucine with physical exercise, seven of leucine paired with another nutrient and without physical exercise, and twelve of leucine paired with another nutrient and physical exercise. The results found that leucine supplementation alone and without physical exercise did not improve markers of sarcopenia, whereas interventions pairing leucine with supplements, particularly protein-supplements enriched with leucine, are a promising treatment for the improvement of sarcopenic markers, whether they are with or without physical exercise. Conclusions: Leucine supplementation, specifically paired with protein supplements, both with and without physical exercise, was found to be an effective dietary intervention for the improvement of sarcopenia. Further dietary interventions are necessary to calculate effective dosage quantities for both leucine and nutrient supplementation as an integral part of the treatment.
