What is L-arginine 1000 mg?

L-arginine 1000 mg from EssentialSeries is a food supplement in vegetable capsules made with the base form of the amino acid L-arginine.

L-arginine is a conditionally essential amino acid. This means the body can manage without getting it from food under normal conditions, but when demand is particularly high, it needs to come from the diet.

Our L-arginine 1000 mg capsules are made without ingredients of animal origin, which means:

Our product is 100 % suitable for vegetarians and vegans.

Why buy L-arginine from HSN?

Completely plant-based

Amino acids are traditionally obtained by processing raw materials of animal origin: mainly bird feathers and mammal fur.

At HSN, we’ve eliminated raw materials of animal origin from all our amino acids. That’s why:

Our L-arginine is produced from plant sources. These undergo a fermentation process using yeast to obtain amino acids, which are then selected and purified to bring you a product suitable for vegetarians and vegans.

What’s more, the capsules, which are normally made from gelatine, have been replaced with a plant cellulose derivative.

With HSN, you can count on quality amino acids.

What products can I take with L-arginine 1000 mg?

Other amino acid products, such as citrulline malate and L-ornithine.

A satisfied customer says:

Ideal to complete your pre-workout.

Raúl | 08/08/2023

If you are looking for a quality pre-workout, with a proven effect on nitric oxide, it works very well, if you combine it with a source of caffeine, it is ideal for this purpose.

Si buscas un pre entreno de calidad, con un efecto sobre el óxido nítrico demostrado funciona muy bien, si lo combinas con alguna fuente de cafeína, pues ideal para tal propósito.

L-arginine 1000mg

Good product

I liked the product, it is good value for money. The composition is good without a thousand extra ingredients added and focusing on the essential amino acid. They are somewhat large capsules, but they can be taken well without noticing any taste.

Me ha gustado el producto, tiene buena relacion calidad precio. La composición es buena sin mil ingredientes extra añadidos y centrandose en el aminoacido esencial. Son cápsulas algo grandes, pero se pueden tomar bien sin notar ningun sabor.
