In addition, it consists of almost 100 % pure L-arginine, whereas arginine HCL only contains around 80 % L-arginine. L-arginine is a semi-essential amino acid that cannot be produced in sufficient quantities by the body in certain situations, such as during stress or intensive training, and must therefore be supplemented. It is the only precursor of nitric oxide (NO), which is responsible for the dilation of blood vessels. L-arginine is also an important component of the body's own collagen and an important building block of muscle proteins.

FAQ: L-Arginine
Where can I buy high-quality L-arginine?
You can recognize high-quality L-arginine by the fact that it ideally consists of only one single ingredient: the amino acid L-arginine (plus capsule shell for capsule products). Unnecessary additives such as flavorings, colorants, fillers, or sweeteners are deliberately avoided. This is exactly what we value at nutri+.

What is arginine good for – and who can benefit from taking it?
Many people ask: What is arginine good for? L-arginine is a semi-essential amino acid and the only precursor of nitric oxide (NO). Nitric oxide has a vasodilating effect and influences blood circulation.
Although our body can produce L-arginine itself, endogenous production may not be sufficient in certain situations. Injuries, stress, or intense training can increase the requirement, making additional intake through diet or supplements necessary.
How much L-arginine should you take per day?
The common recommendation for daily L-arginine intake is 5–6 g.
At higher dosages above 6 g per day, occasional side effects such as bloating or diarrhea may occur.
Can I combine L-arginine with L-citrulline?
Yes, the combination is very popular. L-arginine is directly converted into nitric oxide, while L-citrulline must first be converted into L-arginine, which then also produces nitric oxide. By combining the two amino acids, L-arginine is available to the body over a longer period of time.
You can find our L-Arginine L-Citrulline Mix Capsules here.
Who should not take L-arginine?
People with kidney, vascular, or liver diseases should only use L-arginine after consulting their physician. The same applies if you are taking blood pressure-lowering or vasodilating medications. Pregnant and breastfeeding women should also consult a doctor before taking L-arginine.
If you have low blood pressure, L-arginine should be dosed carefully and increased gradually.
