L-arginina HCl powder by RawSeries is a food supplement based on L-arginine hydrochloride from plant fermentation.
Our L-arginine comes from plant sources that have been treated through a natural fermentation process to obtain the amino acid.
L-arginine HCl powder is therefore a food supplement that is 100% suitable for vegetarians and vegans.
Amino acids from other companies in the food supplement industry are obtained from animal sources, such as mammalian and avian hair and feathers; or from synthesis.
More than 10 years ago, a fermentation-based amino acid extraction process was developed in Asia that has optimised the process of producing pure amino acids suitable for vegans.
HSN uses this technique to produce our amino acid-based food supplements, including our L-Arginine HCl powder.
This product is suitable for vegetarian and vegan diets.
The product has been developed from the pure form of L-arginine HCl, no additives, nothing.
Just the amino acid so you can combine it with whatever you want!
The product has been treated to obtain a micronised raw powder with a very small particle size.
This facilitates their dispersion in the medium and makes their miscibility easier, suspending the particles longer and reducing the % sedimentation.
You can combine it with Citrulina
Arginine powder has a bitter and slightly salty taste.

Excellent
Sergio | 20/11/2025
Very good difference is noticed both for weight training and running, taste a little weird the first time but is well tolerated, then you do not even notice.

A critical customer says:
Bad taste
Vidafitcondani | 22/03/2023
The effect is not so bad but the taste is very bad, with juice it can cover the taste a little bit... But not much
