Athletes often turn to performance-enhancing products to change their body shape, energy levels and muscle volume. One of the ingredients of such supplements is inosine, a nucleoside contained in muscle tissue. The potential benefits of inosine are related to the fact that it acts as a building block for DNA and RNA, helping healthy nerve branches grow from nerves damaged in the brain and spinal cord. It can also help in preserving adenosine triphosphate (ATP), the main form of useful energy in your body. However, its real clinical benefits are still being studied.

Pre-workout supplements designed to improve your athletic performance and provide additional support during exercise have become popular among gym visitors and trainers. As sales of sports nutrition supplements continue to skyrocket, many fitness experts have begun to wonder if these pre-workout products really work, or are they all just hype?

Vigorous exercises can strengthen the health of the heart, lose weight and improve the shape, but also because of them, from one to three liters of fluid comes out with sweat during an intense workout.

Although sweating is a way to maintain a normal internal body temperature (the body cools down), sweat leaches out a large amount of important minerals and dehydration can occur. Isotonic drinks allow you to quickly restore the loss of elements, which prevents some injuries and weakness as a result of training.

Creatine is a natural substance made up of amino acids, the building blocks of protein. Creatine is produced in the liver, kidneys, and pancreas; 95 percent of it is found in the muscles, and the rest is in the brain and heart. In addition to being naturally occurring, small amounts of creatine are also found in foods such as meat and seafood. Synthetic versions are also sold as additives.
