Table of contents
What is L-Ornithine HCl powder?
L-Ornithine HCl powder from RawSeries is a vegan powdered supplement that contains only the amino acid L-Ornithine in its hydrochloride form.
L-Ornithine is an amino acid that participates in the urea cycle in the body and is interconnected with other amino acids like L-citrulline and L-arginine, an essential amino acid.
This is a supplement suitable for use in vegan diets.
Why take L-Ornithine HCl?
L-Ornithine is a non-proteinogenic amino acid involved in several regulatory processes in the body.
In the body, L-Ornithine is produced from L-arginine and converted into L-citrulline in the well-known urea cycle, the main metabolic process involving this amino acid.
Why buy L-Ornithine at HSN?
L-Ornithine is a very rarely isolated amino acid, and those who want to supplement their diet with it usually don’t have the option to do so without combining it with other amino acids.
At HSN we work with the highest quality pure raw materials, offering the widest catalog on the market of RAW format supplements so you can get the products you want to take alone and control your own supplementation.
Vegan amino acid
A vegan amino acid? Yes, it’s possible.
In the supplement market, pure amino acids have traditionally been sourced from animal origins, such as feathers and hair.
At HSN we use an alternative technology newly developed based on fermentation of plant sources to naturally produce amino acids from the nutrients intrinsic to the plant.
These amino acids are then filtered and purified to obtain a raw material of maximum quality and purity.
In HCl form, higher Ornithine proportion
L-Ornithine is combined with another compound to form a salt that improves its physical and nutritional properties.
L-Ornithine hydrochloride is a superior complex compared to many other amino acid salts, as it maintains a high proportion of the 'base' amino acid per unit.
78.4% of the total composition of L-Ornithine HCl is base L-Ornithine.
While other widely marketed salts, like L-Ornithine aspartate, don’t even provide 50% of their composition as the amino acid.
Use only quality supplements. Choose HSN!
Good dispersion
One of the big issues when using RAW amino acid supplements is their poor water miscibility.
With L-Ornithine in HCl form, this characteristic improves drastically, and thanks to its fine particle size, it disperses easily and evenly in water.
That’s why you only need 100-200 ml of liquid to suspend one serving of L-Ornithine HCl, whereas other forms require larger liquid volumes to avoid settling at the bottom of the mixing container.
100% L-Ornithine HCl, flavorless
Our L-Ornithine hydrochloride is a 100% pure supplement:
- No sweeteners.
- No flavors.
- No anti-caking agents.
In short, completely free of additives so you can enjoy the authentic pure product you want to use.
What does L-Ornithine powder taste like?
L-Ornithine powder tastes slightly bitter.
