Amino acids are the building blocks of the enzymes and proteins that help complete almost every major and minor function within the human body. In other words, they are critical to your health. Ornithine is one of twenty amino acid your body uses and is particularly useful for digestion and detoxification processes.
While some so-called body-building supplements that are based on artificial chemicals or protein powders may prove less than effective (or even harmful!), there are natural options that are both safe and powerful. N-acetyl cysteine, for instance, is a naturally-occurring amino acid that can reduce fatigue and decrease muscle damage during intense workouts.
