Arginine is a proteinogenic amino acid that plays an important role in the human body.

Amino acids are the building blocks of proteins and perform numerous vital functions in the body.

Arginine belongs to the semi-essential amino acids, which means that the body can produce it itself under normal circumstances, but in certain situations, such as illness or stress, an additional supply may be required.

One of the best-known functions of arginine is its role in the synthesis of nitric oxide (NO).

In biological processes, arginine is enzymatically converted to NO in the body.

NO is a molecule that promotes the dilation of blood vessels, aiding blood flow and tissue oxygenation.

Citrulline is a non-essential amino acid found in water and melon varieties, as well as in small amounts in the human body.

One of its most notable properties is its role as a precursor to L-arginine.

Because the conversion of citrulline to arginine is gradual, arginine is continually made available in the body.

In contrast, pure arginine can often be broken down quickly.

Due to the increased availability of arginine that results from the conversion of citrulline, the body can produce NO effectively.

A scientific study demonstrated that the combination of arginine and citrulline results in an increase in plasma arginine levels, compared to taking arginine alone (1) .

By taking L-Arginine + L-Citrulline capsules from ZeinPharma® you can optimally support your daily supply of arginine.

Protein block

Provide yourself and your body with the protein building block L-arginine in an optimal way through the quality capsules of ZeinPharma®. It is an amino acid that is used in the body to build proteins, since proteins are compounds  made of several amino acids. Up to 15 percent of our body mass is protein, as for instance the muscles, skin, connective tissue, enzymes and blood cells.


Nobel laureate L-Arginine

With L-Arginine you get a highly regarded amino acid, since in 1998 it helped the three scientists Robert F. Furchgott, Louis J. Ignarro and Ferid Murad to win a Nobel Prize in Medicine. Scientists had explored the relationship between nitric oxide – which can be produced in the body from L-arginine – and a healthy cardiovascular system. Therefore, the knowledge about the potent amino acid is still relatively new. However, since the Nobel Prize was awarded, attention for the amino acid has steadily increased.

L-arginine dilates the blood vessels

L-arginine can help improve the function of your vessels. In the body it is a source of nitrogen. From this, nitric oxide can be formed, which directly influences the walls of the blood vessels as a messenger substance. It causes the blood vessels to dilate and allow the blood to flow through unhindered.


A limited function of the vessels occurs in numerous diseases or life circumstances, such in smokers, diabetics or heart disease. Scientific studies have shown that eating L-arginine can improve the function of the blood vessels and dilate the blood vessels.



Help your body to be optimally supplied with L-Arginine because it is one of the “semi-essential” amino acids. This means that the body can produce L-arginine itself only to a certain extent. However, in order to fully meet the body’s natural amino acid requirement, L-arginine must be externally supplied.


In physical stress situations such as stress, illnessor even sports, the body may have an even higher demand for L-arginine and other amino acids. In such a case, it is important to pay more attention to an adequate supply of the amino acid. The positive properties on the blood vessels make it also popular for active people and athletes.

L-arginine in its free form as a base –

far superior!

With the base you acquire an L-arginine, which is far superior to its related form, namely the L-arginine HCL in conventional articles. There are big differences between the two types available on the market. One of these differences is the pH: L-arginine HCL is acidic, while the base is basic. As a rule, basic foods are better tolerated by the body than acidic ones.

Highest possible purity: 100% arginine

ZeinPharma® L-Arginine Capsules give you the purest L-arginine. The base of the amino acid is 98.5 to 100 percent pure. The L-arginine capsules provide you with 500 mg of the pure amino acid per capsule. This makes the base more pure than the L-arginine HCL. Because this usually only has a content of 25 to 83 percent. Thus, the L-arginine base capsules provide you L-arginine in the best way!

Made without chemicals!

If you are looking for high quality L-arginine, ZeinPharma®’s fermented L-arginine in base form is exactly what you are looking for. Fermentation uses yeast to form L-arginine. You can therefore  be assured that the L-arginine base is free from animal components and hence also animal allergens. In contrast, the chemically produced L-arginine is often produced on the basis of animal sources. Here not only animal, but also chemical residues can endanger the purity of L-arginine.
