But as we age, collagen in our skin can become damaged or may be produced at a lower rate. When the degradation of collagen outpaces the rate of replacement, signs of aging may become evident.
Bioactive type I collagen peptides, plus natural vitamin C,
provide antioxidant support and aid in normal collagen formation.*
With a hint of strawberry flavor, this collagen powder is wildly delicious.
As a general rule, the smaller the peptide, the faster and more complete the intestinal absorption—the best absorption occurs when collagen is broken into peptides of three amino acids or fewer.
We test and re-test our Marine Collagen at standards that are significantly stricter than international measures of quality, and that meet California Proposition 65 safety standards. Need more proof? Check for yourself www.nordicnaturals.com/cofa.
There are over 20 different types of collagen found in the human body, but about 90% is made up of types I, II, and III. Type I collagen is the most abundant in the human body and can be found in skin and other tissues.
Collagen fiber formation begins with three chains of amino acids (polypeptides).
These polypeptides wind together to form a triple helix. Vitamin C is an important co-factor required for the formation and stability of the collagen triple helix.
Individual triple helical strands form inter-molecular bonds—lining up end-to-end, forming a collagen fibril (meaning
Small, hydrolyzed collagen peptides are easily absorbed by the body and stimulate the body’s own collagen-producing cells—fibroblasts, osteoblasts (bone), and chondroblasts (cartilage)—to secrete collagen.* They also supply the necessary building blocks (amino acids) for collagen production.
As we age, the proteins (including collagen) that compose the tissues in skin, joints, bones, blood vessels, etc. can become damaged, degraded, or may be produced at a lower rate.
Vitamin C is an important co-factor required for the formation and stability of collagen.* It’s also a powerful antioxidant capable of neutralizing free radicals.*
A peptide is two or more amino acids linked together in a chain.
Hydrolyzed collagen is collagen that has been broken down into small components (peptides) through a process called hydrolysis. These peptides can then be easily absorbed by the body.
Nordic Naturals Marine Collagen is sourced from the skins of sustainable wild cod, which are caught for human consumption.
Type I and type III collagens are both ‘fibril-forming’ collagens and are very similar in general structure and amino acid composition. In humans, type III collagen is often found in the same tissues as type I (namely the skin), but in much smaller amounts. The type I collagen used in Nordic Naturals Marine Collagen is the most abundant type in both the human body and in the cod skins it comes from.
While there have not been sufficient studies comparing the effects of type I and type III collagen, several studies have suggested that the most bioactive peptide of collagen—the peptide that best promotes building connective tissue—is made up of three amino acids: glycine-proline-hydroxyproline. Type I collagen has a higher prevalence of gly-pro-hydroxyproline units, and thus a greater potential than type III collagen to yield these bioactive peptides.
Because type I collagen may be a richer source of bioactive collagen peptides and is made from an environmentally responsible source (fish skin), Nordic Naturals selects this form of collagen for our Marine Collagen.
