Main highlights

L-arginine high dose: with 6000 mg per day, the L-arginine capsules ensure the best possible supply of the body with this special amino acid. We use a high-quality arginine in the base form, which can be optimally absorbed by the body thanks to its basic (alkaline) pH value.
Taking 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.
Made in Germany and laboratory tested: the production of L-arginine capsules takes place exclusively in Germany. As part of our quality assurance, we have the L-arginine capsules regularly analyzed by an independent food laboratory.
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: our L-arginine capsules contain pure L-arginine (in base form) with an L-arginine content of full 100%. Other arginine forms contain significantly less L-arginine - for example, L-arginine HCL contains only 83% and L-arginine AKG (AAKG) even only 54% L-arginine.

We have the capsules regularly examined by an independent laboratory and can therefore guarantee first-class quality. Image in the picture gallery.

Main highlights

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 exclusively in Germany. As part of our quality assurance, we have the L-arginine capsules regularly analyzed by an independent food laboratory.
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.
Arginine and citrine: 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.

Main highlights

Premium raw materials: We use high-quality L-Arginine in the "base" form. Unlike L-Arginine HCL, it is not bound to hydrochloride, but 99.7+% pure L-arginine. Our arginine with citrulline comes from vegetable fermentation from corn (GMO-free). It has a basic pH value, which makes it particularly compatible and digestive friendly. In addition, we use citrulline which has a depot function because it is gradually converted into L-arginine.
Made in strictly controlled plants and without undesirable additives and 100% vegan: Free from flavouring and colouring agents, undesirable stabilisers and (of course) lactose-free, gluten-free, free from preservatives and genetically modified ingredients (GMO-free).
Excellent value for money: High quality L-Arginine base with L-citrulline. High dose with 3000 mg L-arginine and 426 mg L-citrulline per daily dose (3 x 2 capsules). With 365 capsules.
Every production batch is laboratory-tested: Many manufacturers rely on the specifications of their raw material suppliers. A few have their products checked by a laboratory. Nature Love goes one step further: we let the raw material or product of each individual production batch be tested by an independent German laboratory.
