The study aimed to assess the safety and, partially, the efficacy of dietary supplementation of a flavonoids-, DHA- and EPA-based natural supplement in non-ambulant DMD boys and in a cohort of LGMD and FSHD patients to compare its effect in MDs of different aetiology and to eventually highlight any differences in inflammatory involved pathways. To assess safety, patient's laboratory parameters were monitored and adverse events recorded, while efficacy was evaluated through performance scale questionnaire and strength measurement (6 minute walking test and Biodex System 4 Dynamometer parameter evaluation). This study was conceived as proof of principle for the safe use of flavonoids/omega3s-based compound as an adjuvant in the management of neuromuscular disorders; besides, its efficacy in alleviating symptoms linked to secondary effects of genetic mutation as inflammation, muscular pain and weakness was assessed.
