Portable device for glutathione measurement

Professor Kouretas has patented a method for the assessment of GSH in a single drop of human capillary blood (Registration Number: TX 8-580-623) which is collected from the finger (Figure 1).

The multi-year research activity of FoodOxys scientific team led to the creation of a database with the metabolic profiles of 4,000 people. The database is a unique, intangible asset of the company from which the normal distribution of GSH levels in human population has been derived (Figure 2). Therefore, based on the values measured by the device, each person is classified into one the following categories:

Category I: Values 3.5-6.0 (Normal)
Category II: Values < 2.5 (Pathological)
Category III: Values 2.5-3.5 (Potential presence of metabolic disorder)
Category IV: Values > 6.0 (High values, attention required)

Figure 2. Normal distribution of GSH levels in human population.

Red: Very low values – hazardous to health
Orange: Low values – attention required
Green: Increased values – attention required
Dark green: Normal values – Maintain a balanced diet

As previously mentioned, the need for dietary antioxidants depends on the endogenous GSH levels (Figure 3). Dietary antioxidants contribute to the maintenance of normal GSH levels, thus promoting human health.

Figure 3. The relationship between the endogenous GSH concentration (μmol/g Hb) and the amount of antioxidants required to be obtained through the diet.

Based on the above, the quantity of the dietary antioxidants that are essential on a daily basis is calculated. The necessary amount of antioxidants can originate from a combination of food products that have been assessed for their antioxidant content.

Finally, a personalized nutrition plan is created by the company’s specialized staff based on the requirements and needs of each person.
