The study was designed as a randomized, placebo-controlled trial with follow-up at 3 months. The study is in accordance with the Declaration of Helsinki and was approved by the Institutional Bioethical Committee of the National Hellenic Research Foundation. All the study participants received informative material, filled a questionnaire regarding the self-assessment of their health status and nutritional habits, and signed their written informed consent. In total, excluding the participants that did not return for the follow-up (dropouts), 122 apparently healthy volunteers of age 29-85 were followed, with 43 of them being randomly assigned in the placebo subgroup and 79 receiving the composition of the present invention.

All the study participants received informative material, filled a questionnaire regarding the self-assessment of their health status and nutritional habits, and signed their written informed consent. Patients eligible for the inclusion criteria were randomized into two groups: the group of healthy adult volunteers that received a capsule with the active formulation and those the received the placebo (a capsule with only the carrier substance magnesium stearate) In total, excluding the participants that did not return for the follow-up (dropouts), 122 apparently healthy volunteers of age 29-85 were followed, with 43 of them being randomly assigned in the placebo subgroup and 79 receiving the composition of the present invention.

| Effect of the formulation on oxidized proteins' levels | Oxidative stress states can be indicative of an impaired antioxidant defense. The study focused on the assessment of oxidative stress status by the protein carbonyls' levels before and after the intervention. | 3 months |
| Measure | Description | Time Frame |
|---|---|---|
| Analysis of the effect of the formulation on oxidized proteins' levels adjusted for sex, age, and lifestyle habits of the sample as assessed in the study's questionnaire | Analysis adjusted for specific parameters to reveal potential confounders of the primary outcome of the intervention. | 3 months |
| Correlation of levels of oxidized proteins and measured 20S proteasome levels |
