Main highlights

NAC - the better cysteine: L-cysteine is an amino acid that serves as a building block for proteins. NAC is a precursor of L-cysteine as it is converted into L-cysteine in the body. Since L-cysteine oxidizes very quickly and thus loses its effect, NAC is preferred to increase L-cysteine levels in the body as it is more stable and is oxidized more slowly. NAC also has better bioavailability than L-cysteine, so it can be absorbed and used better by the body.
German production: our N-acetylcysteine NAC capsules are manufactured exclusively in Germany to the highest quality standards. They are free from any additives. To ensure optimal quality, we do not test our acetyl cysteine capsules like other suppliers only for microbial impurities, but also for pesticide, aluminium and heavy metal residues. Of course, our product is non-GMO and suitable for vegans: inside.
From fermentation: for our NAC 600 capsules (n-acetyl-l-cysteine) we use 100% pure NAC powder from fermentation. It is not produced synthetically like almost all other products. As a basis for fermentation, we use corn and not soy. Good to know: Sulphur-containing amino acids have a typical smell that can be perceived as unpleasant. However, we rely on naturalness and have deliberately opted against odour-binding additives.
Antioxidant glutathione: gluthathione is a powerful antioxidant that provides protection against free radicals and plays an important role in detoxifying harmful substances. It consists of the amino acids L-glutamic acid, L-cysteine and glycine and is found in almost all cells of the body. L-Cysteine in turn plays an important role in the formation of glutathione. Since our body cannot produce enough L-cysteine itself, it must be supplied (for example in the form of NAC).
Always there for you: We want to inspire you - that's why we develop innovative products based on the needs of our customers. We make sure to carefully combine and dose the ingredients so that the ingredients develop their effect optimally. We are happy to advise and support you in your goals.

Tested quality. The presence of a sulphuric smell, which is perceived by most people as unpleasant and sometimes as a taste, does not indicate a change in the supplement, but is typical of NAC (which contains sulphur). The smell is therefore a sign of the naturalness of the N-acetylcysteine-containing product. Bandini Pharma's NAC 220 capsules are based on a rigorous selection of raw materials. Our product is of course GMO-free.
NAC capsules 600 mg - L-cysteine is quickly absorbed by the body and combines with N-acetyl to enhance its effect. The minimum additional intake of acetylcysteine for adult men and women is 600 mg per day.
Discover N-acetyl cystone: Acetylcysteine, known as NAC, is a derivative of the amino acid cysteine and a precursor of glutathione. It is usually found in protein foods such as meat and eggs. Finally, acetylcysteine intervenes in various body functions to keep you fit all year round.
Choose our N-acetyl cysteine NAC - Our purely vegetable NAC contains 220 capsules for a supply of +7 months. Our strong formula consists of 600mg N-Acetyl Cysteine per capsule to provide you with sufficient daily intake.
