Why is zinc so important for the human body

Zinc has enjoyed great popularity as a dietary supplement for some time and belongs to the group of essential minerals. In other words, this means that the body cannot produce zinc itself. It is therefore dependent on zinc being supplied through food or in the form of supplements, as otherwise many functions in the human body cannot function properly. According to scientific studies, zinc is a key component of over 300 vital enzymes in the body (1,2,3). Among other things, it is required for wound healing, the correct functioning of the immune system, protein synthesis, carbohydrate and fat metabolism, the production of important anabolic hormones as well as cell growth and cell division (4,5). Conversely, this means that all these important bodily functions can be impaired without sufficient zinc intake. According to studies, the average diet of many people often does not provide sufficient amounts of zinc (6). To make matters worse, athletes who train intensively usually have an increased need for zinc, which often cannot simply be covered by food alone (7). A lack of zinc led to numerous deficiency symptoms in test subjects in various studies. These included symptoms such as lack of drive, poor concentration, reduced immune function, night blindness, impaired sense of taste and smell, delayed wound healing, brittle fingernails, hair loss and reduced levels of muscle-building hormones (8).

Benefits of zinc in weight training

In addition to general health, which contributes significantly to optimal muscle building, there are a whole range of benefits that are particularly important for strength athletes. As already mentioned, zinc is of crucial importance when it comes to optimal hormone levels. Wherever the body relies on hormones, zinc plays an important role, for example in the thyroid gland, pancreas, pituitary gland and sexual organs (8,9). This in turn means that an optimal level of the mineral has a positive effect on the metabolism in general as well as significantly influencing the production of hormones such as testosterone, which in turn has numerous important effects on muscle building (10). In studies, supplementation with zinc was able to help test subjects to optimize hormone production and thus achieve significantly better results in terms of their athletic performance and body composition (11). Bodybuilders and strength athletes also report accelerated regeneration between training sessions with zinc supplementation, which may be due to the fact that zinc is required for the repair of training-induced microtraumas (12).

Why zinc in citrate form?

The citrate form of zinc can offer several advantages for the human body compared to other forms of zinc. For one, zinc citrate is generally well tolerated by the gastrointestinal tract. Compared to other forms of zinc, such as zinc sulphate, studies have shown that gastric complaints or digestive problems occur much less frequently (13). Zinc citrate is more stable in the acidic environment of the stomach than some other forms of zinc. This enables better absorption in the intestine, as the zinc can pass through the stomach without losing its bioactive form (14). Another advantage is the bioavailability of zinc citrate. It is well absorbed by the human body and has excellent bioavailability. This means that the body can use the zinc from the citrate form efficiently and thus benefit optimally from it (14).

The GN Laboratories quality guarantee

At GN Laboratories, we only ever use the purest and highest quality ingredients on the market. This means that we can always guarantee the consistent quality of all our products, which always meet the highest standards. In addition, each of our products is regularly tested in the laboratory for the purity and quality of all its ingredients. In this way, we can guarantee that nothing stands in the way of an optimal effect.

Zinc is a mineral that plays an incredibly important role in the human body. If you consider the many functions that zinc influences in the human body, it quickly becomes clear why it has been an important constant as a supplement for many years. With Zinc Citrate, GN Laboratories supplies the mineral in an optimally absorbable form so that you can benefit from it to the full extent. Zinc Citrate from GN Laboratories - because in the end only results count.
