Scientists were able to determine the level of human vitamin C without a blood test

The most common way to determine the concentration of substances in the body on the current day is a blood test. It not only allows you to find out the content of vitamins, hormone levels and other indicators of human health but also can help diagnose diseases and the presence of dangerous viruses. However, this method is invasive, that is, it requires direct penetration into the body, and not everyone often has the opportunity to take a blood test. People with diabetes, for example, have to carry portable devices with them that can measure their blood sugar. Over the past few years, scientists have begun to create wearable sensors that allow you not to take a blood test to determine the concentration of a single substance. One of these recently introduced researchers from the United States and Switzerland.

Vitamin C sensor

Scientists have been able to develop a device that can measure the level of vitamin C in the human body, without direct penetration under the skin. They made a sensor that can detect the content of this vitamin in regular sweat! It allows you to monitor the level of this substance without a blood test and thus maintain it within acceptable limits.

Vitamin C Test

To realize this idea, the researchers placed a special enzyme on one of the sensor electrodes, due to which the vitamin C molecules that enter the sensor react with oxygen. Then the sensor measures the change in current, which occurs due to the fact that with an increase in the concentration of vitamin C, part of the oxygen is spent on their oxidation. In other words, the device does not work with vitamin C itself, but with the change in current that occurs due to this reaction. And already on this indicator makes conclusions about the content of substances in the body.

The device is specially designed so that in the place of contact with the skin cause increased perspiration – otherwise, it simply will not work. For example, if you put on such a sensor in the winter, you can not sweat at all, and the vitamin content will not be calculated. However, the sensor is designed so that even small particles of sweat are enough to determine the level of a substance in the human body.

To test the performance of the device, scientists conducted additional studies, calculating the level of vitamin C in an invasive way – the indicators turned out to be the same. Volunteers were also involved who put the device on hand before taking tablets containing vitamin C and before drinking orange juice, which has a high content of this substance. Experiments have shown that changes in the sensor readings correlate quite well with vitamin C intake.

Vitamin C Benefits

Why even monitor the content of such a substance in the body? Vitamin C is a powerful water-soluble antioxidant. In the human body, it is necessary for the synthesis of collagen.

If a person has low levels of vitamin C, he may later have problems not only with blood vessels but also spots on his skin and weak bones. Therefore, if doctors find out about this, they are asked to donate blood periodically to monitor the content of this substance.

Vitamin C

Regular consumption of foods rich in this vitamin helps the human body protect itself from scurvy (a disease that occurs when vitamin C is deficient). Increasing immunity, it develops resistance to pathogens of infection and cleanses the body of harmful, contributing to inflammatory processes.

How to increase vitamin C levels?

To do this, you need to eat foods rich in vitamin C – for example, sweet red pepper, orange, and lemon. Kiwi fruits are also an excellent source of antioxidant vitamin C, providing 154% of the daily intake of this essential vitamin. Eating foods rich in vitamin C contributes to the body’s immunity to infectious agents. Fresh strawberries are also an excellent source of vitamin C. 100 grams of these berries contain 58.8 milligrams of this vitamin, which is 98% of the recommended daily intake.

In the future, a method discovered by American and Swiss doctors can help determine the concentration of many substances in the human body without a blood test. The main thing is to choose the right catalyst – with the help of which a chemical reaction will start, and the device can thus measure the substance content.
