N-Acetyl-L-cysteine, 60 capsules

NAC plus N‑Acetyl‑L‑Cysteine for sulphur supply and cellular protection

The amino acid L‑cysteine is a source of sulphur for our body. It is important for the formation of many proteins (e.g. creatine and insulin) and can stabilise their structure by forming disulphide bridges.

Around 500 amino acids exist in nature. 20 of these amino acids act as building blocks for the proteins found in the human body; they are referred to as “fundamental amino acids”. These fundamental amino acids are divided into the categories “essential”, “semi‑essential” and “non‑essential”. Cysteine, a semi‑essential amino acid, can be synthesised by the body from L‑methionine. However, under certain conditions this synthesis is not sufficient to meet requirements. Cysteine, like methionine, is one of the two fundamental sulphur‑containing amino acids. N‑Acetyl‑L‑Cysteine, abbreviated NAC, is the acetylated form of cysteine.

N‑Acetyl‑L‑Cysteine (NAC) as a food supplement offers several advantages compared with L‑cysteine: it is better tolerated, has higher bioavailability and is less prone to oxidation. After ingestion, NAC can be converted into cysteine, which is part of certain body proteins. In addition, cysteine is one of the precursors of glutathione, which is produced by the biosynthesis of the amino acids cysteine, glycine and glutamic acid.

Vitals, our new brand from 2025

We are constantly on the lookout for brands that represent our ideals: highest quality, the consistent omission of unnecessary additives such as titanium dioxide or porcine gelatin, excellent value for money and absolute reliability in delivery to us and thus to our customers.
This is very difficult because such companies are extremely rare among the mass of dietary supplement manufacturers now on the market. But we have once again managed to find one with Vitals from the Netherlands!

Address of the manufacturer: Vitals Voedingssupplementen BV, Pieter Lieftinckweg 29, 1505 HX Zaandam, Netherlands. E-mail: kundendienst@vitals.eu.
