Collagen is a protein found in the skin, bones, cartilage and connective tissue. As a food supplement it is most often sold as a powder in sachets. What does the information on the label mean?
Hydrolysed collagen
In supplements collagen is usually hydrolysed. This means the protein is broken down into shorter chains (peptides), so the powder dissolves well in water or another drink.
Types of collagen
- Type I – the most common type of collagen in the body.
- Type III – often found together with type I.
- Type II – found mainly in cartilage.
The label also shows the source: bovine, fish (marine) or chicken collagen. Fish collagen is not suitable for people with a fish allergy.
How much collagen is in a dose
Check how many grams of collagen one daily dose (one sachet or scoop) contains and how many doses are in the pack. The amounts differ a lot between products.
Why vitamin C is added
Vitamin C contributes to normal collagen formation for the normal function of the skin, blood vessels, bones, cartilage, gums and teeth. That is why many collagen drinks contain added vitamin C, for example from rosehip.
Other ingredients
Collagen drinks often also contain hyaluronic acid, plant extracts, flavours and sweeteners. All ingredients must be listed on the label in descending order by weight.
Example: Collagen with hyaluronic acid
One sachet of Biostile Collagen Powder + Hyaluronic Acid contains 5500 mg of bovine collagen type I and III, 3000 mg of fish collagen type I, 100 mg of bovine collagen type II, 50 mg of hyaluronic acid and 50 mg of vitamin C from rosehip (63 % NRV). Stir the sachet into a glass of water, one sachet a day. It comes in three flavours: pineapple, strawberry and mango. All products are in the category Collagen.
