Health condition and Intervention

Section to complete information about the primary medical condition(s) or problem(s) studied and, a characteristics of the intervention(s).

Health condition(s) or Problem(s) studied:

Healthy volunteers

Intervention(s):

Group I ADIPONEXIN (Experimental): 2 capsules of ADIPONEXIN will be administered every 12 hours, by oral route, for 90 days with meals containing oil or fats (4 capsules in total). The capsule is a probiotic formulation that combines the action of the probiotic bacteria Lactobacillus reuteri with marine collagen peptides, hyaluronic acid, and the carotenoid astaxanthin Group II ReuteriBiotic (Experimental): Two ReuteriBiotic capsules will be administered every 12 hours, by oral route, for 90 days with meals containing oil or fat (4 capsules total). The capsule is a probiotic formulation that combines the probiotic bacteria L. reuterii with the prebiotic fructooligosaccharides and magnesium stearate as an excipient Group III Placebo (Control): Two microcrystalline cellulose capsules will be administered every 12 hours, by oral route, for 90 days with meals containing oil or fat (4 capsules total)

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Bioimpedance Measurements (Using the TANITA TANITARD-545 InnerScan PRO Segmental instrument will be measured the Subcutaneous fat vs. abdominal visceral fat, Body Mass Index (BMI), Waist circumference and Lean muscle mass). Mesurement time: At baseline, 45 days and, 90 days

Key secondary outcomes:

1. Clinical chemistry parameters (A Cobas 600 modular immunoassay autoanalyzer (Roche Diagnostics) will be used. The analysis will be performed on serum samples in Fasting glucose (mmol/L), Creatinine (umol/L), Cholesterol (mmol/L), Triglycerides (mmol/L), C-Reactive Protein-hs-CRP-(mg/L), IL-6 (pg/mL), Insulin (U/ml), TSH (mIU/L), Hb A1C(%), Testosterone (nmol/L), Estradiol F (pg/ML)). Measurement time: At baseline and, 90 days 2. Leptin (It will be determined by an ELISA test Human Leptin ELISA Kit (abcam ab108879)). Measurement time: At baseline and, 90 days 3. Adiponectin (It will be determined using the Human Adiponectin ELISA Kit (abcam ab314604)). Measurement time: At baseline and, 90 days 4. Oxytocin (It will be determined using the Oxytocin ELISA Kit (abcamab133050)). Measurement time: At baseline and, 90 days 5. Serum LPS levels (It will be determined using the ELISA test using the commercial ToxinSensorTM Endotoxin Detection System Version 11242021 kit). Measurement time: At baseline and, 90 days 6. Fecal Calprotectin levels (It will be determined using the fCAL test, 200T, cobas c 501/502, PCh 200 tests). Measurement time: At baseline and, 90 days 7. Hemodynamic parameters (Heart rate (beats per minute), Blood pressure (mmHg)). Measurement time: At baseline and, 90 days 8. Bacterial composition of the specific fecal microbiome (It will be determined by sequence studies of the 16S ribosome subunit (16S rRNA V3-V4) in stool samples. Taxonomic Profile and compositional analysis will be used. The taxonomic profile analysis will be performed using PICRUSt to determine the Inflammation Index, Alpha Diversity and Beta Diversity. The compositional analysis will be performed using the prediction analysis of functional markers (orthologous genes) from the study of the microbiome using LEfSe (Linear discriminant analysis Effect Size)). Measurement time: At baseline and, 90 days 9. Quality of Life (SF-36 Health Survey in Spanish). Measurement time: At baseline and, 90 days 10. Adverse events and its intensity (It will be measured by considering the presence of the adverse effect under four categories (No apparent adverse effect, Possible adverse effect, Similar to an adverse effect, Adverse effect) and its intensity classified into three categories (Mild, Moderate, Severe)). Measurement time: During the study, up to 90 days
