Main highlights

Take before training: L-arginine is ideal for taking before training and is therefore also included in many pre-workout supplements. We recommend 8 L-arginine capsules approx. 30 minutes before training.
Laboratory tested and made in Germany: the production of L-arginine capsules takes place in Germany and is therefore subject to the strict German guidelines for the production of dietary supplements. We have the capsules regularly examined by an independent laboratory and can therefore guarantee first-class quality - laboratory analysis certificate see picture gallery.
L-arginine high dose: 6000 mg pure L-arginine per daily dose. We use 100% L-arginine base, the arginine form with the highest bioavailability and a basic (alkaline) pH value - optimally tolerated for the body.
L-arginine from fermentation: cheap L-arginine is made from hair or duck feathers. On the other hand, we use a high-quality L-arginine, which is obtained by fermentation from vegetable raw materials and therefore 100% vegan.
100% L-arginine content: the NatureWell L-arginine capsules contain pure L-arginine base with an L-arginine content of 100%. Other forms contain significantly less L-arginine. For example, L-arginine HCL contains only 83% and L-arginine AKG (AAKG) even only 54% L-arginine.

Take before training: The amino acids L-arginine and L-citrulline malate are ideal for taking before training and are therefore also included in many pre-workout supplements. We recommend 8 capsules L-arginine + L-Citrullin 6000 approx. 30 minutes before training.
Optimal high dose: with a total of 6000 mg amino acids per day, the capsules ensure an optimal supply of the body with L-arginine and L-citrulline. The daily portion thus provides 33% more amino acids than ordinary L-arginine capsules with only 4500 mg.
Made in Germany and laboratory tested: the production of L-arginine capsules takes place in Germany. As part of our quality assurance, we have the L-arginine capsules regularly analyzed by an independent food laboratory.
Arginine and citrulline: the capsules contain a perfectly coordinated combination of the amino acids L-arginine and L-citrulline malate. The daily serving (8 capsules) provides 2400 mg L-arginine and 3600 mg L-citrulline malate, which in turn contains 2400 mg of pure L-citrulline.
Amino acids from fermentation: Cheap amino acids are often made from hair or duck feathers. We only use amino acids for L-Arginine + L-Citrullin 6000 capsules, which are obtained by fermentation from vegetable raw materials and therefore 100% vegan.
