Biomarkers are substances present in blood serum or in other body fluids and tissues. their recognition can be an indicator of “aging”.
The main biomarkers now identified are:
• Chronic inflammation
• protein glycation
• Deficit of methylation
• Mitochondrial aging
• Hormonal imbalances
• Alteration of the profile of essential fatty acids
• Genetic polymorphisms
• Alteration of digestive enzyme function
• Oxidative stress
The study of some of these markers is performed with blood samples followed to the correction of altered parameters through the use of nutraceuticals or nutritional supplements.
