Collagen type I and III

What does collagen type I and III mean?

Collagen is a structural protein that occurs in the body in several types. Type I is the most abundant and is found mainly in skin, tendons and bones; type III often occurs together with type I. Collagen for food supplements is usually made from bovine hide or fish – both sources provide mostly type I and III.

Type II, on the other hand, is typical of cartilage and is mostly made from chicken sternum. It is a separate product group and is not included here.

Hydrolysed collagen and peptides

Most products contain hydrolysed collagen, also called collagen peptides or collagen hydrolysate. The long protein chains are broken down into shorter peptides, so the powder dissolves even in cold drinks. Branded raw materials such as Peptan are named on the label.

Our range

• Osavi Collagen Hydrolysed Type I & III as a powder – unflavoured or with apple, raspberry, or cherry and strawberry.
• Skill Nutrition Hydrolysed Collagen Type I & III in pineapple, blood orange or grapefruit.
• Doctor's Best Collagen Types 1 and 3 as tablets with vitamin C, as a version with Peptan (3000 mg) and as a pure powder.

Vitamin C contributes to normal collagen formation for the normal function of skin, which is why many brands combine the two. Collagen itself is a protein; we do not attribute any particular effects to it here.

What to look for

• Source: bovine or fish – important if you avoid certain raw materials.
• Amount per serving: powders usually provide several grams per serving, tablets much less.
• Flavour and extras: unflavoured for stirring in, or flavoured; with or without vitamin C and sweeteners.
• Dose: follow the directions on the label.

Food supplements are not a substitute for a varied diet.

Frequently asked questions

What is the difference between collagen type 1 and type 2?

In products, type I (usually with type III) comes mostly from bovine hide or fish, type II mostly from chicken cartilage. They are different raw materials with a different composition.

Can I stir collagen powder into coffee?

Hydrolysed collagen dissolves in hot and cold drinks. Unflavoured versions are best for this.

Is marine collagen also type 1?

Yes, fish collagen consists mainly of type I. It is an alternative for anyone who does not want bovine collagen.
