Background: COVID-19 left consequences in different organs from months to years requiring different types of rehabilitation. In fact, a severe loss in the lung function, and in the respiratory and peripheral muscle strength is commonly observed in post-COVID-19 patients. Objectives: Thus, the present study investigated whether 30 days of supplementation with a nutritional blend (ImmuneRecov®; composition: whey protein concentrate, astaxanthin, creatine, selenium, vitamin C, glutamic acid, tryptophan, magnesium) would help to minimize the respiratory (lung function) and muscular (respiratory and peripheral muscles) sequelae in post-COVID-19 patients.

Design: This is a non-controlled open label prospective clinical study. Methods: Fifty-eight post-COVID-19 patients were recruited and twenty-four accepted to take the nutritional blend, while twenty-four did not accept but required to participate in the evaluations and 10 refused to participate. So, the patients were evaluated before the 14th day after hospital discharge and after 30 days of use of the nutritional blend or control (no supplementation).
