Quit smoking without nicotine

  • Removes acetaldehyde from saliva during smoking.
  • Reduces the adverse effects of smoking if you are not able to quit.
  • Contains xylitol, which improves oral health. Poor oral hygiene increases local acetaldehyde formation.

Acetium lozenges contain L-cysteine, which is a natural amino acid. L-cysteine effectively binds acetaldehyde from saliva and forms a harmless compound that can be excreted from the body.

L-cysteine removes over 90 per cent of the acetaldehyde dissolved into saliva during smoking. The recommended dosage is 1 or 2 lozenges during smoking.

*Acetium lozenges do not reduce other adverse effects of smoking, nor do they remove carcinogens other than acetaldehyde. It is recommended to quit smoking due to all its adverse effects.

A Finnish innovation

Developed and manufactured in Finland, the Acetium lozenge is free of the side effects of conventional smoking cessation methods, such as nicotine dependency or possible adverse effects of medication.

How does Acetium work?

The effectiveness of Acetium lozenges in smoking intervention has been evaluated in two clinical trials (1, 2). Regular use of the lozenge during smoking increases the likelihood of quitting by a factor of 1.5 compared to a placebo (2).

Acetium lozenges contain L-cysteine, a natural amino acid that efficiently binds acetaldehyde dissolved in saliva from cigarette smoke and converts it into a harmless compound (3).

Acetium® lozenges contain no harmful ingredients. In addition to L-cysteine, the lozenges contain a small amount of xylitol to reduce the production of acetaldehyde by bacteria in the mouth and improve oral hygiene.


The active substance of lozenge is slow dissolving L-cysteine (3 mg/tablet). Other ingredients: xylitol (250 mg/tablet) (E967), sorbitol (224 mg/tablet) (E420), smoke flavor, anise flavor, magnesium stearate (E470b), silicon dioxide (E551). Tablet weight 500 mg. Does not contain lactose, gluten or nicotine.

What is acetaldehyde?

Normal saliva does not contain acetaldehyde (3). Acetaldehyde is a carcinogen (4) and one of the harmful substances in tobacco smoke. The Acetium lozenge removes up to 90% of smoke-derived acetaldehyde in saliva.
