It has been demonstrated that consequences of malnutrition affect a situation of risk and have negative effects on the evolution of chronic obstructive pulmonary disease (COPD), accompanied by higher morbidity and mortality. The impact of malnutrition on the respiratory system affects the respiratory muscles, the lung parenchyma, and the immune system. In summary, the risk of complications can lead to a worsening of the quality of life of the COPD patient. Also, dyspnea as the main symptom of COPD is the one that produces the greatest loss of quality of life, especially in older patients. The components of our authorized food supplement improve the quality of life of the patient. These components maintain the strength and energy of the patient, help the body to recover and regain its optimal state, help improve the immune system, help reduce the side effects of therapies associated with the control or cure of cancer and help correct nutritional deficiencies. This is the reason why this experimental study aims to improve the quality of life in patients with COPD with a CAT score>15.

This study is developed in two phases: pilot phase and experimental phase. The pilot phase is preliminary and progressive in order to demonstrate a sufficient effect of improving the quality of life of patients and to be able to continue in an experimental phase with more investigational sites and more patients, and to evaluate other secondary objectives.

Once the pilot phase is finished, an intermediate analysis of the results will be carried out to evaluate the magnitude of the variation in quality of life at 3, 6, 9 and 12 months. If the expected success expectations are achieved and it is approved by the Ethics Committee, the study will continue to the experimental phase.

Inclusion Criteria:

• Adults: men and women ≥ 18 years.

• Patients who are trained to give informed consent.
• Patients must agree to perform study visits and procedures with precise instructions.

Exclusion Criteria:

• Comorbidities, which due to their severity or progression, may interfere with the results, such as cancer, hematological disorders, severe heart or liver failure, kidney failure on dialysis, tuberculosis (TB) or AIDS, or other pulmonary pathologies such as pulmonary thromboembolism ( PE), pulmonary fibrosis, or relevant bronchiectasis.
• In Pulmonary Rehabilitation treatment or in treatment for smoking.
