What is L-ornithine?

L-ornithine is a so-called semi-essential amino acid, formed from the amino acid arginine in liver metabolism. Together with other amino acids, L-ornithine is needed to synthesise important enzymes in the organism. The non-proteinogenic amino acid is an important intermediate in liver metabolism, and thus plays a crucial role in the urea cycle as a carrier substance. It is known, that L-ornithine plays important functions in detoxification in liver and cell metabolism. Although the organism is able to produce L-ornithine to some degree, production decreases with age. L-Ornithine capsules from ZeinPharma® can balance this deficiency well, and thus provide your body with an optimal supply of this important amino acid.

Natural and highly bioavailable

To ensure adequate supply of the amino acid L-ornithine, it is recommended to use it as a dietary supplement. Your advantage is that with L-Ornithine capsules from ZeinPharma® you receive first-class and tested product quality in standardised form. This gives you the security even with a longer-term intake.


Those who take supplements should always make sure that they can be well absorbed by the organism and introduced into the cell metabolism. It has been shown that L-ornithine in free form, as it is also contained in the capsules of ZeinPharma®, is absorbed particularly well by the body and gets absorbed by the intestinal mucosa. This bioavailability is an important indicator of a dietary supplement. The capsules from ZeinPharma® therefore always provide you with an optimal supply of the important amino acid L-ornithine.

100% natural from fermentation

In order to ensure optimal bioavailability for the body cells, at a supplementation with L-ornithine, the high product quality is crucial. The capsules of ZeinPharma® contain 100 % natural L-ornithine from fermentation. In this reliable process, L-ornithine is synthesised through controlled enzymatic reactions from the amino acid L-arginine. It is a standardised and strictly monitored manufacturing process that always provides you with excellent product quality in every capsule. With the ZeinPharma® capsules, give your body pure, natural L-ornithine with excellent bioavailability.

What you should know about how L-ornithine works in your metabolism

Cell metabolism cannot function smoothly without the presence of L-ornithine. Because the amino acid supports the body in numerous important functions. For instance, L-ornithine is involved in various detoxification processes of the body. As part of the urea cycle in liver metabolism, the organism gets rid of the waste products with the help of L-ornithine of the toxic ammonia. Because without L-ornithine as a carrier substance, the toxic ammonia could not be converted to urea. In this complicated chemical process, ammonia is bound to the amino acid L-ornithine. Together with water, urea is formed, which can then be excreted in the urine. In addition, L-ornithine is also involved in the construction of many other amino acids and can also be converted into a variety of other amino acids.

L-ornithine and L-arginine are closely related

In cell metabolism, the functions of Ornithine and Arginine cannot be separated in interaction. Chemically, the two amino acids are very similar in terms of structure. In the urea cycle, the amino acid L-ornithine is formed from L-arginine. Under the influence of both amino acids, there is also the activation and release of growth hormone and insulin. These two hormones, in turn, are essential for cell energy production, muscle building and fat burning. With ZeinPharma® L-Ornithine capsules, you will receive an innovative product that will help you sustain these anti-aging processes in your body.

Benefit from the high degree of purity

Each and every new batch undergoes rigorous quality control in our in-house laboratories. Only when all the tests have been passed properly, the capsules go on sale. The L-ornithine in the capsules of ZeinPharma® is at least 99 percent pure. The production is based on the natural model in the body, where L-ornithine is also obtained through enzymatic reaction of L-arginine. The remaining one percent is due to chemically pure water, which must be used in the manufacturing process. This almost negligible amount of water is completely safe within the dosage and has no effect on capsule and body.

Provide your body with valuable L-Ornithine

If you consume three capsules of ZeinPharma ®L-ornithine daily, you provide your body with 1176 mg of pure L-ornithine to. This daily intake recommendation is suitable as a dietary supplement over a longer period. The raw materials come exclusively from controlled, non-animal sources for the production of ZeinPharma® L-Ornithine capsules. Therefore, the capsules are particularly suitable for people who prefer the vegetarian or vegan diet. Especially vegetarians or vegans may be particularly affected by the deficiency of certain amino acids, including L-Ornithine. With the addition of ZeinPharma® L-Ornithine capsules, you have the advantage of being able to prevent deficiencies.
