Studies document the effects of collagen
What does science say about Copenhagen Health's collagen products?
In 2023, Rousselot published an in-depth report on the efficacy and impact of the collagen peptides (Peptan) that we use in Marine Collagen Pro Edition , Bovine Collagen Pro Edition , Marine Collagen+ and Bovine Collagen+ respectively. The report summarizes the results of a number of scientific studies conducted by researchers from both European and international universities.
All studies were double-blind (neither participants nor researchers knew who received which treatment), randomized
(participants were randomly assigned to groups) and placebo-controlled (the treatment was compared to an inactive placebo).
Below we will present the findings from the studies that
included in the report.

Marked reduction of wrinkles
In 2022, researchers at the University of São Paulo investigated
the effect of Peptan from cattle (bovine collagen) on wrinkles. The study involved 60 women aged 45–60 years, and after 90 days of treatment with Peptan, wrinkles around the eyes were reduced by an average of 13%, while wrinkles around the mouth were reduced by 10% (Campos et al, 2022).
Compared to the placebo group, where there was only a modest reduction, the study showed that Peptan effectively reduces wrinkles and has a positive anti-aging effect on the skin.
After 90 days of treatment with Peptan, the wrinkles around
The wrinkles around the eyes of the participants in the Peptan group were reduced by an average of 13%. Wrinkles around the mouth were reduced by 10%.

Significant improvement in skin moisture levels
A study conducted in Japan in 2008 examined the effects of Peptan F (fish) on skin moisture levels. 33 women aged 40–59 participated, and after 8 weeks of daily intake of Peptan F/marine collagen, participants experienced an average increase in skin moisture levels of 12% (Asserin et al, 2015). In addition, they found that the skin’s ability to retain moisture remained unchanged.
Skin moisture levels increased significantly in the Peptan group (average 12% after 8 weeks) compared to
A high level of moisture is important for improving skin elasticity and structure.

Reduced the breakdown of skin collagen fibers
A 2012 study conducted in France involved 106 women and focused on the effect of Peptan on skin collagen content. The results showed that Peptan increased the amount of collagen in the skin by an average of about 9% after 12 weeks, leading to firmer and fuller skin. In addition, Peptan reduced the fragmentation of collagen fibers by 31.2% after 12 weeks, making the skin stronger and more intact (Bossier, 2023).
The statistics show that the collagen content in the Peptan group increased by 9% over a period of 12 weeks, while the collagen content in the placebo group remained unchanged.
The statistics show that Peptan reduced collagen fragmentation by an average of 31.2% after 12 weeks, resulting in a stronger collagen structure compared to the placebo group.

The women in the studies experienced after 12 weeks on average:
