Maqui and Omega 3: effects on lipid profile, oxidative stress levels and psycho-physical items in human subjects


Aims: to assess short-term efficacy of supplementation with Maqui (Aristotelia Chilensis (Mol.Stuntz)), a polyphenol with antioxidant power, and EPA/DHA concerning metabolism, oxidative stress and mental/physical state. Patients and Methods: a pilot prospective observational clinical/laboratory study was performed on 17 apparently healthy subjects (8 males and 9 females, mean age 47 years). All subjects received for two months: a) Maqui 600 mg per day and b) 360 mg of EPA and 240 mg of DHA (salmon oil) daily. At day 0 and day 60 all subjects underwent nine laboratory tests related to inflammation, metabolism (lipid profile mainly) and oxidative stress parameters. Pre-post treatment weight and BMI was calculated. A few physical and mental parameters were assessed by means of Short-Form 12 questionnaire. Statistical analysis was applied to the resulting data through Wilcoxon test and t-paired test. Results: laboratory results before and after Maqui + EPA/DHA supplementation were respectively (mean and p-value for the comparison): total cholesterol 228.8/199.8 mg/dl, p=0.23; low density lipoproteins 127.4/122.1 mg/dl, p=0.13; high density lipoproteins 59.1/57.6 mg/dl, p=0.25; Reactive C Protein 0.18/0.09 mg/dl, p=0.32; triglycerides 106.1/91.1 mg/dl p=0.09, glycemia 92.9/92.8 mg/dl p= 0.92; total free radicals 338.0/303.6 U.Carr., p=0.002; serum anti-oxidant capacity 2075/2190 umol/l, p= 0.04; oxidized lipoproteins 641.8/553.1 uEq/l, p=0.10. SF12 physical and mental items (mean values and SD) were 51.2 (+/- 6.2) and 41.2 (+/- 3,3) at day 0 and 54.6 (+/- 11.6) and 47.2 (+/- 9.7) at day 60 respectively. One case of transient constipation was recorded. Conclusions: daily supplementation with Maqui 600 mg + Omega 3 fatty acids (EPA 360 mg + DHA 240 mg) in apparently healthy middle-aged subjects resulted in a statistically significant improvement of oxidative stress parameters. An overall (non statistically significant) improvement of dysmetabolism biomarkers was achieved. Mental and physical parameters have mildly improved.
