What is L-Arginine HCl Powder?
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.
Why buy L-Arginine HCl at HSN?
Vegetable origin
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.
100% RAW
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!
Good solubility
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.
How to combine L-Arginine HCl powder?
You can combine it with Citrulina
How does L-Arginine HCl powder taste?
Arginine powder has a bitter and slightly salty taste.

A satisfied customer says:
Overall very good.
Miguel | 07/01/2024
Results are noticeable after two weeks, with a slight increase in endurance and strength, especially in aerobic activities.

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
