N-Acetyl-L-cysteine, 60 capsules

NAC plus N-acetyl-L-cysteine for sulphur supply and cell 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 sulphur bridges.

There are around 500 amino acids found in nature. Twenty of these amino acids act as building blocks for the proteins found in the human body; they are known as ‘essential amino acids’ .  These essential amino acids are classified into the categories ‘essential’, ‘semi-essential’ and ‘non-essential’ . Cysteine, a semi-essential amino acid, can be synthesised by the body from L-methionine. Under certain conditions, however, this synthesis is insufficient to meet the body’s requirements. Cysteine, like methionine, is one of the two fundamental sulphur-containing amino acids.  N-acetyl-L-cysteine, or NAC for short, is the acetylated form of cysteine.

N-acetyl-L-cysteine (NAC) as a dietary supplement offers several advantages over L-cysteine: it is better tolerated, has higher bioavailability and is less prone to oxidation.  Once ingested, NAC can be converted into cysteine, which forms part of certain bodily proteins . Furthermore, cysteine is one of the precursors of glutathione, which is produced through 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: The highest quality, consistent omission of superfluous additives such as titanium dioxide or porcine gelatine, very good value for money and absolute reliability in delivery to us and therefore also to customers.
This is very difficult because such companies are extremely rare among the mass of manufacturers of food supplements that are now on the market. But we have managed to find them again, with Vitals from the Netherlands!

Manufacturer's address: Vitals Voedingssupplementen BV, Pieter Lieftinckweg 29, 1505 HX Zaandam, Netherlands. E-mail: customer service@vitals.eu.
