Overweight
Conditions
Brief summary
The objectives of this clinical study are to determine the tolerance of dietary supplement Valedia (blend of plant extracts) through the evaluation of several parameters : * Various blood biological parameters for tolerance (preprandial): blood glucose, insulin, fructosamine, total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, oxidized LDL, us-CRP, creatinine, ASAT, ALAT, gGT, phosphatase alcaline, bilirubine, urea. * Urinary parameters: urea, creatinine. * Hemodynamic parameters: heart rate and blood pressure. * Cardiac function: ECG. * Weight.
