Introduction

Naringin is a flavonoid used as a dietary supplement, which is marketed in products for athletes, is promoted as enhancer of other supplements, increases physical capacity and as a “fat burner” for weight loss, among other effects. Objective: To evaluate the available evidence of the effect of oral naringin supplementation in combination with physical activity and / or exercise on clinical responses compared with physical activity and exercise alone.

Material and Method

A systematic search was carried out in electronic databases. Data sources were Science Direct, MEDLINE, PubMed, Web of Science, Cochrane Central Register of Controlled Trials, SPORTDiscus. Selection of studies was publications aiming to study the effects of naringin in combination with exercise or physical activity. Data extraction and synthesis method: Two reviewers analyzed data; data extracted: authors, year of publication, study design, universe of study, intervention and relevant results; quality was quantified with the PEDro scale. The review was carried out following the PRISMA guidelines.

Results

Three clinical trials were identified (mean PEDro score of 8.3). Naringin improves physical activity time and decreases fatigue time, and subjectively improves physical condition but was not statistically better than placebo.

Conclusions

Studies show contradictions about the effects of the combination on physical fitness.
