What is zinc?

Zinc is an essential trace element that the human body cannot produce itself. This means that it must be supplied through food or in the form of supplements to ensure optimal supply. Zinc has enjoyed regular use since ancient times and has always been one of the most widely used supplements. It is involved in a variety of important processes in the body (1,2,3,4) and is an essential component of over 300 vital enzymes. An adequate supply of zinc provides numerous benefits to the human organism. Researchers have demonstrated through numerous studies the positive influence of zinc on the body's production of important anabolic hormones (5,6,7). Studies have also shown that the trace element plays an important role in the optimal metabolism of protein, fat and carbohydrates (8,9). For athletes in particular, these two aspects are of enormous importance. They enable both muscle building and fat burning (8,9). This in turn means that a zinc deficiency could have a direct negative influence on these processes (9). Another aspect that should be of particular interest to athletes is accelerated regeneration after training. This is related to the fact that zinc is urgently needed for the repair of training-induced microtraumas in muscle tissue (10).

Zinc is also used in the field of dermatology, for example, to counteract skin impurities (11) and has already been successfully used in studies on test subjects with certified depression (12). In addition, zinc has an antiviral effect (1) and has been shown to improve the function of the immune system in various scientific settings (1,13). A functioning immune system greatly decreases susceptibility to infectious diseases (14). Zinc is a component of a variety of enzymes responsible for the breakdown of pollutants, heavy metals, and toxins in the body. Through this key role, the trace element could potentially significantly support the body's natural detoxification processes in one study (15).

The trace element is also an essential component of the body's antioxidants, and increased zinc intake can therefore support the neutralization of free radicals in the body (16). Elevated levels of free radicals can damage the body's cells and DNA. In addition, they are associated with the development of a variety of diseases (17). Because free radicals accelerate the body's aging process, elevated levels of endogenous antioxidants are considered by many scientists to be a natural anti-aging therapy (18,19).

Athletes have an increased zinc requirement due to regular physical exertion and the increased loss of minerals and trace elements through sweat. Vegetarians and vegans also often have difficulty meeting their zinc needs because they do not consume animal sources of zinc. However, a predominantly plant-based diet has an additional effect with regard to zinc. It is rich in phytates. These inhibit the absorption of zinc in the digestive tract, which makes it even more difficult for the body to obtain an optimal supply. Zinc requirements increase with age, and the body also needs larger amounts of zinc during pregnancy (20).

Why Zinc Bisglycinate

In zinc bisglycinate, the zinc atom is bonded to two amino acid molecules. This structure is much less attacked by gastric acid and also survives the enzymes in the duodenum largely undamaged. In the small intestine, a very high percentage of zinc bisglycinate is absorbed into the bloodstream by special transport systems. Compared to zinc gluconate and zinc citrate, zinc bisglycinate boasts a bioavailability that is over 40% higher.

Zinc Bisglycinate by GN Laboratories provides all the benefits of the essential trace element in the form best utilized by the body. So you can be sure that your body is always optimally supplied.

Important: Zinc is considered an essential trace element and a deficiency can result in many negative consequences. However, an overdose of zinc can also lead to many negative consequences (1,20). For this reason, supplementation should always be done with caution.
