That is why you must choose collagen powder that contains collagen from fish
Collagen powder can be extracted from various sources such as cattle or pig, but collagen from fish is preferable for several reasons:
- Collagen from fish is absorbed more easily by the body than other sources
- Collagen from fish consists of type-1 collagen which makes up 80-90% of the body’s total collagen proteins
- Less climate-damaging than other sources (if it originates from sustainable fishing)
1. Collagen from fish is absorbed more easily by the body than other sources
The higher the bioavailability, the more efficiently collagen is absorbed into the body. Studies indicate that collagen from fish is absorbed up to 1.5x better in the body than collagen from cattle (bovine). It simply means that more of the collagen you consume is absorbed into the body.

Collagen from fish consists of type-1 collagen, which makes up 80-90% of the skin’s total collagen proteins
There are over 28 different types of collagen in the body. The most common type is Type-1 collagen, which makes up 80-90% of the skin’s total collagen proteins. Marine collagen consists exclusively of type 1 collagen. With marine collagen, you get as much type-1 collagen as possible. Collagen from cattle typically contains both type-1 and type-3, which are found to a lesser extent in the skin.
Less harmful to the climate than other sources (if it comes from sustainable fishing)

Worldwide, food production accounts for 25% of global climate emissions1, but some foods cost more in the climate account than others. Therefore, it does matter for the climate which source your collagen comes from.
Did you know that: Nutrinic is the only Danish collagen brand that is certified by ASC, which is the leading certification scheme for sustainable fish farming. Our collagen is a surplus product from food production and would otherwise be discarded.
Fish production has a smaller CO2 footprint than cattle production2. But different fish and shellfish can have varying climate impacts and animal welfare. Therefore, we recommend that you look for collagen powder that is sustainability certified by ASC or MSC.
