L-ornithine 500mg - 120 capsules

L-ornithine: amino acid for physical performance, muscle building and fat reduction

Within the liver metabolism, L-ornithine is of central importance for the detoxification of the body. The amino acid is involved in the formation of urea and is needed to remove excess ammoniac from the liver.

L-ornithine is of great importance for the building processes of the muscles and the reduction of fats. That is why it is important during diets and exercising. It is able to prevent the ammoniac level in the blood from rising during exertion and prevents weariness.

Japanese researchers examined the influence of L-ornithine on the physical exhaustion. During this trial, 17 healthy test persons either received 2 grams of L-ornithine for seven days and 6 grams of L-ornithine on the eighth day or a placebo, followed by a physically exhausting bicycle ergometer training. The test persons, who had received ornithine, reported significantly less tiredness than the test persons, who had received a placebo. Furthermore, the female test persons showed a higher physical performance on the bicycle ergometer.

L-ornithine is also an important factor for the release of growth hormones. This is why it is a popular anti-aging product, which helps to provide a youthful appearance. It is able to activate the immune system and to support the defence processes against pathogenic germs, because it stimulates the formation of white blood cells.

Furthermore, L-ornithine has the potential to reduce stress and to improve the sleep quality, which was examined in a randomised double-blind study with participants who had been suffering from mild stress and tiredness. The test persons were divided into two groups. One group consumed 400mg L-ornithine daily; the other one received a placebo. The serum levels of cortisol (stress hormone) and dehydroepiandrosteronsulphate (DHEAS, adrenal cortex androgen) of all test persons were analysed. Additionally, mood and sleep quality were determined during the study. The result of the eight-week study showed significantly reduced cortisol and DHEAS levels. The feeling of anger decreased, whereas the sleep quality improved.

Vegetarians and vegans should ensure an adequate supply with L-ornithine, because the amino acid occurs primarily in animal-based food. Plant-based foods contain only traces of L-ornithine.
