What are collagen peptides?

introduction

Collagen peptides are a frequently mentioned term in the areas of nutrition, skin, and connective tissue care. But what are they, how do they work—and why is marine collagen often highlighted?

Definition and production

Collagen peptides, also called hydrolyzed collagen , are formed when long-chain collagen molecules are broken down into short amino acid chains .
This hydrolysis process facilitates absorption in the small intestine because the smaller peptides are easier to digest.

Once absorbed, these peptides are available to the body as building blocks for connective tissue such as skin, cartilage and bones.

Scientific findings

Studies show that regular intake of hydrolyzed collagen can have positive effects on skin moisture, elasticity and joint function .
Examples from scientific journals (including Skin Pharmacology and Physiology , 2014; Osteoarthritis and Cartilage , 2012) indicate improved skin elasticity and support of normal cartilage structure .
These results are promising, but do not represent a cure or preventative claim .

Possible areas of application

• Skin & connective tissue: Supports the natural skin structure and moisture balance

• Joints & Cartilage: Supplying the body with important amino acids for connective tissue

• Bones & Muscles: Supplementing your daily protein intake

Why marine collagen is particularly valued

Fish collagen (marine collagen) offers several benefits:

• Low molecular weight → good bioavailability

• Rich in type I collagen , which is also found in human tissue

• Sustainable origin : Extracted from fish skins and scales that would otherwise remain unused

Intake and use

Collagen peptides are tasteless and dissolve in cold or warm drinks such as water, tea, coffee or smoothies.
Depending on the product, we recommend about 5 to 10 g per day , combined with vitamin C , which supports the body's own collagen production .

Ballstad Salmon Collagen – Example of Quality

• Norwegian origin: Strict standards for purity and sustainability

• Type I collagen: Obtained from high-quality salmon skin, for good absorption

• Sustainable & free from additives: No fillers or artificial colors

This product stands for clean origin and scientifically sound production without promising any medical effects.
