Is a key electrolyte in the regulation of water and electrolyte metabolism, which translates into maintaining optimal fluid balance and stabilizing blood pressure in the body. Together with potassium, they form an ideal combination, as both are integral parts of the sodium-potassium pump, which actively moves sodium ions outside the cell and potassium ions inside. This balance maintains the potential difference at the cell membrane, which is essential for generating electrical impulses, transmitting nerve signals and initiating muscle contractions.

Carnitine is an organic compound made from the amino acids lysine and methionine. Thanks to L-carnitine, long-chain fatty acids can enter the mitochondria, the energy centers of the cell, where they are converted into the energy necessary for the body to work during exercise. However, the spectrum of action of L-carnitine is much broader. Among other things, the compound is responsible for buffering excess lactic acid in cells and aiding post-workout recovery.

Carbohydrate-electrolyte solutions are a key part of a strategy to rehydrate and provide energy to the body during exercise*.
