L Ornithine HCl is an amino acid that is considered an essential part of the diet, and is required for a number of functions within the body. L Ornithine is useful as a building block for the proteins used in the growth and repair of tissue, and also carries out a number of services within the body including acting as a precursor of the pituitary gland. For anyone engaged in a long term physical training plan, getting the right dietary balance is absolutely essential. The body requires the right kind of nutrients in order to perform and develop correctly, and whether these come from food or from supplements, they are needed for many purposes. L Ornithine is a naturally occurring amino acid that can be found in small quantities in a variety of foods including meat and seeds. For maximum benefits however, it is necessary to supplement the diet with additional sources of L Ornithine in order to enjoy its full effects. Amino acids like Ornithine are used in the cells as the building blocks for proteins, which are used to repair and build new tissue. Ornithine also has a number of other benefits that make it even more useful than other amino acids for anyone who is in training. L Ornithine metabolises in the body, and this is necessary for keeping tissue supple and flexible and is particularly required in the heart for maintaining healthy tissue throughout the cardio vascular system and ensuring that the heart muscle is able to work effectively.
