Supplements play an important role in the lives of athletes, helping them to improve their training and athletic performance. They are becoming more and more popular, so it is worth knowing how to make them. Below you will find the most important information about the substances that are included in the composition of dietary supplements. Be sure to read on!

What do dietary supplements for athletes contain?

Athletes need additional nutrients to achieve peak performance. Dietary supplements are a great addition to the diet because they provide important ingredients that normal meals alone cannot provide in sufficient amounts. Dietary supplements can speed up muscle recovery, increase endurance, improve concentration, and support an athlete’s overall development.

Dietary supplements for athletes consist mainly of proteins and amino acids, but they also contain other chemical compounds such as Caffeine and creatine.

Protein in dietary supplements for athletes

Protein is an essential ingredient for athletes, as it is the building block of muscles. It can come from a variety of sources, such as whey, casein, soy or legumes. In addition, protein supplements may contain various additives such as vitamins, minerals, creatine, fiber or pro- and prebiotics, depending on the purpose and intended effect.

Taking protein supplements is very important because they support muscle building and recovery after intense training.

Amino Acids in dietary supplements for athletes

Amino Acids  are also very important for athletes, as they are basic components of proteins and play an important role in the body’s metabolic processes. In dietary supplements for athletes amino acids perform several important functions – they increase muscle recovery, improve endurance and build muscle mass.

Most often in the composition of dietary supplements you will find BCAAs (Branched Chain Amino Acids), i.e. amino acids with branched side chains that the body cannot produce itself. These include leucine, isoleucine and valine.

Popular ingredients in dietary supplements for athletes

In the world of dietary supplements for athletes, there are a number of popular ingredients that can influence the achievement of better training results and improve recovery. Four important substances are worth mentioning: Beta Alanine, Whey Protein Concentrate, Caffeine and Creatine. Each of these ingredients has its own unique properties and benefits for athletes. Below you will find descriptions of their effects.

Dietary supplements for athletes

Beta Alanine

Beta Alanine  is a chemical compound that belongs to the group of amino acids produced by the body. It is a β-amino acid, which means that its structure is such that the amino group is attached to the β-carbon atom in relation to the carboxyl group.

The main function of Beta-Alanine is to stimulate the production of carnosine in the muscles, which helps prevent the formation of Lactic Acid, which is responsible for muscle soreness after exercise. In addition, Beta-Alanine reduces the feeling of fatigue and muscle soreness after exercise. Carnosine acts as an antioxidant and can help remove excess metals from the human body.

Beta-Alanine is used in the production of dietary supplements for athletes who specialize in very intense physical activities. Although carnosine has many beneficial properties, it is supplemented with Beta-Alanine because carnosine is rapidly broken down after absorption through the digestive tract.

Whey Protein Concentrate

Whey Protein Concentrate (WPC) is produced by processing sweet whey using advanced ultrafiltration technology at low temperatures. The result is a product with a protein content of at least 80%.

WPC is used by athletes because it is rich in essential amino acids necessary for building muscle tissue. It also contains branched-chain amino acids, which stimulate the regeneration of muscle tissue and initiate anabolic processes.


Caffeine is an alkaloid that stimulates the central nervous system. It is obtained by extraction from plant seeds, but it is also produced synthetically by chemical synthesis.

Caffeine acts primarily as a stimulant, which in turn can contribute to prolonged exercise. It increases the performance of the body, quickly eliminates the feeling of fatigue and dilates blood vessels. Caffeine is available in the form of pills and also in powder form.


Creatine is an organic chemical compound that occurs naturally in muscles. On an industrial scale, it is obtained by chemical synthesis.

Creatine is used in dietary supplements for athletes because it plays an important role in supplying the muscles with energy during intense physical activities.
