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 necessary. 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, thereby aiding blood flow and oxygenation of tissues.

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. Since the conversion of citrulline to arginine is gradual, arginine is continuously 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 effectively produce NO. A scientific study has shown that the combination of arginine and citrulline results in increased plasma arginine levels, compared to taking arginine alone1. By using the L-Arginine + L-Citrulline capsules by ZeinPharma® you can optimally support your daily supply of arginine.

Frequently asked questions

What is L-arginine and how does it differ from other amino acids?

L-lysine is a semi-essential amino acid that the body can only produce itself to a limited extent and should therefore be taken in with food. L-arginine is particularly important for building proteins and plays a role in various metabolic processes in the body.
L-Citrulline is an amino acid that occurs naturally in the body and is also found in certain foods. Compared to other amino acids, which are mainly building blocks for proteins, L-Citrulline is distinguished by its involvement in nitric oxide production, which can lead to dilation of blood vessels.
Generally, it is possible to open the capsules without danger. For example, the powder can be stirred into a drink or meal. If you do not like the taste, it may be useful to use a fruit juice instead of water, for example, to mask the taste.
The L-Arginine + L-Citrulline 500 mg capsules can be used alternatively to or between meals.
You can store the capsules at normal room temperature in a dry environment. As long as it is protected from direct sunlight, you are otherwise free to choose the storage location.
The L-Arginine + L-Citrulline 500 mg capsules can be used permanently without any risk. Usually there are no side effects.
Usually there are no side effects as long as the consumption recommendation is followed.
