N-Acetyl Cysteine Powder by RawSeries is a vegan powdered dietary supplement based on N-acetyl Cysteine of vegetable origin.
N-acetyl cysteine is the acetylated version of the amino acid cysteine. This form of the amino acid alters its structure and characteristics. The amino acid has been obtained through fermentation processes from vegetable sources.
The dietary supplement is suitable for consumption by vegetarians and vegans as there has been no presence of elements of animal origin during the manufacturing process.
Want to know what makes the HSN supplement unique?
Amino acids are traditionally obtained in two ways:
- Treatment of animal tissues (such as duck feathers or mammalian hair).
- Chemical synthesis.

An emerging technology that has been widely used in Asian biotechnology laboratories for more than 10 years, using plant foods to obtain amino acids.
This is achieved by using yeasts that ferment carbohydrate-rich sources, such as corn.
The result is pure amino acids, without traces of other nutrients, and of vegetable origin.
N-Acetyl Cysteine Powder is an amino acid obtained through these vegetable fermentation processes.
N-acetyl cysteine is an amino acid that follows our RawSeries range philosophy.
100% pure raw materials, powdered products, free from additives that alter product concentrations.
N-acetyl cysteine contains only, and exclusively, pure amino acid.
A more durable format, our N-acetyl cysteine powder is a presentation that, thanks to its low daily required dose, can last for months.
With a single 150g bag you'll have N-acetyl cysteine for more than a year of use!

The plant origin of the amino acid and the complete absence of excipients make N-acetyl cysteine powder a product 100% suitable for vegetarians and vegans.
N-Acetylcysteine has an intensely bitter and acidic taste.

Good
Dani | 24/11/2025
An indispensable supplement in my daily routine. Does what it promises. Good value for money.

A critical customer says:
Difficult taste
Aitor | 06/06/2017
The smell and taste are very strong and acidic. It is necessary to take it with something strong, although as it is taken in small quantities it is not a problem. In tablets it would be easier to take.
