Professional Performance Check

Professional Performance Check

Are you feeling stressed, unmotivated, tired, and unable to concentrate? More than 60% of people are stressed. Their work performance is reduced and their mental health suffers.

The comprehensive bundle is aimed at people who want to quickly and easily reach maximum professional performance. With a simple blood sample test, you can check your vitamin D and vitamin B12 blood levels.

The 'nerve vitamin' B12 enhances concentration and memory and is of particular importance in the case of a stressful work life.

Vitamin D deficiency leads to symptoms such as fatigue, lack of motivation, as well as circulatory problems and a weakened immune system. Hence professionals who mainly work in an office should have their vitamin B12 and vitamin D levels checked in order to prevent or remedy existing deficiencies.

  • Extensive check to help you maximise your job performance
  • Simple to use test kits to check your vitamin D and vitamin B12 level
  • Vitamin B12 is essential for the ability to focus and your memory
  • Vitamin D is essential for many bodily functions–lack of vitamin D can cause listlessness, lack of strength, and weakened immune system
  • Designed for professionals who tend to work inside and have limited access to direct sunlight

The Professional Performance Check contains the following tests:

Vitamin D 

Vitamin D, which is actually a hormone, is increasingly present in the media— and rightly so. According to various studies, most people working in an office suffer from vitamin D deficiency, despite its high importance for the vital functions of the human body. In more than 30 essential bodily functions alone it plays a key role. As up to 90% of vitamin D is produced by full body sun exposure, it is highly likely that these people suffer from a deficiency. Moreover, certain diets or other nutritional deficiencies may aggravate the vitamin deficiency. In many cases, the vitamin D level in people affected lies below 31 nanograms per milliliter (ng/ml) and thus below the minimum level advised by orthomolecular physicians. They recommend a vitamin D level of 40-60 ng/ml as a target value. You should check your vitamin D level several times per year.

Vitamin B12

You should not only pay attention to your vitamin D level. A vitamin B12 deficiency can also considerably reduce performance and stamina. Vitamin B12 is an essential vitamin. This means that the vitamin must be taken in by consuming certain foods as the human gut bacteria can only produce it in negligible quantities. In brief, this means that a deficiency is preprogrammed without a regular and sufficient intake through the diet. Vitamin B12 as a coenzyme contributes to many vital metabolic processes like nerve protection and nerve regeneration, cell division and cell respiration, synthesis of messenger substances and detoxification. In particularly stressful periods, your vitamin B12 requirement may even rise. For the release of the stress hormones noradrenaline and serotonin, lots of vitamin B12 is needed. On top of this, stress reduces the blood flow to the digestive organs and thus the metabolization of cobalamin (vitamin B12). Stress, in this context, means all types beginning from major mental effort and physical strain (physically demanding work and competitive sports) up to anxiety, lovesickness and grief or recurrent infections. Due to the functions of vitamin B12 and the additional demand in a fast-paced working environment, symptoms of a deficiency–reduced stress resistance, concentration problems and signs of fatigue–may result.
