The study conducted by German consultancy, analyze & realize, featured 199 healthy adults aged 18-70 who reported at least three colds in the previous six months.

Placebo groups took either a 4.5g daily larch arabinogalactan supplement of or a placebo for 12 weeks.

Participants recorded common cold episodes in a diary and rated 10 predefined infection symptoms. The episodes were all confirmed by doctors.

“The present study demonstrated that larch arabinogalactan increased the body’s potential to defend against common cold infection. While the immunomodulatory effect of arabinogalactan can be assumed, its mechanism of action remains to be elucidated,”​ the researchers said.

After publication, a Lonza spokesperson said the study was a breakthrough for the ingredient and would be used as a global marketing tool.
