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.

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

Vegetable raw material: our vegan L-arginine is obtained by fermentation from sugar cane and Jerusalem artichoke, without genetic engineering and free from additives. It is a purely plant-based, semi-essential, proteinogenic amino acid for optimal care.
Vegan and without unnecessary additives: our L-arginine capsules stand for high quality and are purely plant-based. They contain no added flavours, dyes, stabilisers or gelatin and are also GMO-free, lactose-free, gluten-free and free from preservatives. Whenever it is technologically possible, we deliberately refrain from using additives for a product as natural as possible.
VIT4EVER Quality: The Vit4ever range offers a wide range of dietary supplements for different needs. Our products are made from high-quality raw materials and produced in carefully selected EU factories to ensure consistently high quality. Vit4ever - German brand quality since 2016.
Pure L-arginine: Our L-arginine capsules contain only L-arginine in the high-quality base form with a purity of 99.7%. Compared to other dosage forms such as L-arginine HCL (≈ 83% L-arginine content) or L-arginine alpha-ketoglutarate (≈ 54% L-arginine content), the base form offers the highest proportion of pure L-arginine.
L-arginine high dose: our high-dose L-arginine provides 6000 mg of pure L-arginine base per daily serving and thus ensures an optimal supply of this proteinogenic amino acid. We only use high-quality L-arginine in the base form, which has a neutral, basic pH value compared to L-arginine HCL. This makes our product particularly suitable for people who value a pure and readily soluble arginine quality.
