Ornithine is a non-proteinogenic amino acid, which means it is not typically used for muscle protein synthesis but plays a crucial role in metabolism. In the body, it is closely related to arginine and the urea cycle, where it helps remove toxic ammonia. In the world of sports nutrition, it has become popular primarily due to claims that it can naturally stimulate the hormonal system.
Glycine is a non-essential amino acid, which, in terms of chemical structure, is the simplest of all 20 amino acids commonly found in proteins. Although the body can synthesize it itself, it plays several specific and indispensable roles in an athlete's body. However, is its supplementation significant for athletic performance?
Taurine is a non-proteinogenic amino acid and a derivative of the amino acid cysteine, which has become a very popular ingredient in many sports and energy drinks in recent decades. Although it is found in the human body in high concentrations in the brain, heart, and muscles, its exact role still remains partially a mystery to science.
L-citrulline is a non-essential (not necessary to be consumed in food) non-proteinogenic (not a building block for muscles) amino acid that occurs in human diet only in small quantities. Its main natural source is watermelon, but the body can also synthesize it itself. In the field of sports nutrition, citrulline has gained great popularity due to its ability to increase arginine levels in the body and support nitric oxide (NO) production.
D-Aspartic Acid (DAA), found in the body in the form of aspartate, is an amino acid that is often presented as a means to increase energy and delay fatigue. But what does modern sports science really say about it?
Learn the science behind beta-alanine: how it works, how much to take, and why it can help you during high-intensity exercise.
Suplementace dusičnany se stala jedním z nejvíce zkoumaných témat moderní sportovní vědy. Zatímco v minulosti byly dusičnany považovány za pouhý vedlejší produkt metabolismu, dnes víme, že hrají klíčovou roli v regulaci krevního průtoku, svalové kontrakce a buněčné energetiky. Hlavním přírodním zdrojem těchto látek ve sportovní výživě je šťáva z červené řepy. Pojďme se podrobně podívat na konkrétní vědecké studie, které zkoumaly vliv dusičnanů na lidské tělo, a na reálné výsledky, kterých sportovci dosáhli.
