Collagen Supplements Explained: A Plain-English UK Guide

Collagen is one of the most heavily marketed supplement ingredients, and one of the most confusingly described. Labels say "hydrolysed", "peptides" and "type I", and packaging often implies more than the rules allow. This guide explains what collagen is, what those words mean, where it comes from, and how to read a collagen label.

It does not make claims about what collagen does for your skin or joints, because there are no authorised health claims for collagen itself in Great Britain.

What Is Collagen?

Collagen is a protein. It is a major structural part of the body, found in skin, bones, tendons, cartilage and other tissues, and the body makes its own. Collagen supplements provide collagen from another source, usually an animal.

Like other proteins, collagen you swallow is broken down during digestion. What happens to it afterwards, and whether it makes a measurable difference to the body, is a subject of ongoing research rather than settled fact.

What Does "Hydrolysed" Mean?

Whole collagen is a large molecule. Hydrolysed collagen has been broken down into smaller pieces, called peptides, to make it easier to mix and take. On labels you may see it written as "hydrolysed collagen", "collagen peptides" or "collagen hydrolysate". These generally mean the same thing.

Where Does Collagen Come From?

Supplement collagen is made from animal by-products, most commonly:

  • Bovine: from cattle, usually hides or bones
  • Marine: from fish skin or scales
  • Porcine: from pigs

This has practical consequences. Collagen supplements are not suitable for vegetarians or vegans. Marine collagen is a fish allergen. If you avoid certain foods for religious or ethical reasons, the source matters, so check the label or ask the brand.

Products sold as "vegan collagen" do not contain collagen. They generally contain other ingredients, such as vitamins, minerals and amino acids, marketed as supporting the body's own collagen. That is a different product, and it is worth knowing the difference before you buy.

What About the Research?

There are studies on collagen supplements, including on skin and joints. Treat them with care. They vary in size and quality, some are funded by the companies that make the products, and results are mixed. A study is also not the same as an authorised claim. That is why this guide does not say what collagen will do for you, and why you should be cautious of any product that does.

Where Do Vitamin C and Biotin Come In?

Many collagen products add nutrients that do have authorised claims. In Great Britain:

  • Vitamin C contributes to normal collagen formation for the normal function of skin, as well as blood vessels, bones, cartilage, gums and teeth.
  • Biotin contributes to the maintenance of normal skin and normal hair.

These claims are about vitamin C and biotin. They are not claims about the collagen itself, and they apply only when the product contains enough of the nutrient. Check the amounts on the label.

Gummies, Powders or Capsules?

Collagen powders often provide several grams of collagen per serving. Gummies and capsules usually provide less, because of how much fits in each one. That does not make one format right or wrong, but it does mean you should compare the amount of collagen per serving and the cost per day, rather than assuming products are equivalent. Gummies also contain a small amount of sugar and often other ingredients, so read the full label.

Who Should Check First?

Speak to your GP or pharmacist before taking collagen if you:

  • are pregnant or breastfeeding
  • take prescribed medication
  • have a medical condition
  • have a fish, beef or gelatin allergy or intolerance

This is general information, not medical advice.

How to Read a Collagen Label

  • Source: bovine, marine or porcine, and whether it suits your diet and beliefs.
  • Hydrolysed or not, and the type if stated.
  • Amount of collagen per serving, in milligrams or grams, and how many gummies or scoops make a serving.
  • Vitamin C and biotin amounts, if included.
  • Other ingredients: sugars, syrups, gelling agents and colours.
  • Allergens and diet information.
  • Claims: be cautious of products that promise specific results.

Where RISE Fits

RISE Collagen Complex Gummies contain 500mg of hydrolysed bovine collagen per gummy, with vitamin C (48mg) and biotin (50µg). The serving is one gummy a day, and a bottle holds 90. They are orange-flavoured and made in the UK, with no artificial colours. They contain bovine collagen and gelatin, so they are not suitable for vegetarians or vegans. The full ingredients and nutritional information are on the product page.

You can pair them with a hair, skin and nails formula in The Glow Ritual, or browse our glow range.

Frequently Asked Questions

Are collagen gummies vegan?
No. Collagen comes from animals, so collagen gummies are not vegetarian or vegan. Plant-based products sold as "vegan collagen" do not contain collagen.

What is hydrolysed collagen?
Collagen that has been broken into smaller peptides. It is the form most supplements use.

Do collagen supplements work?
Studies exist, but results are mixed and there are no authorised health claims for collagen itself. We do not make claims about what it will do for you.

How much collagen is in a gummy?
It varies by brand. Check the amount per serving on the label. RISE Collagen Complex Gummies contain 500mg per gummy.

Can I take collagen with other supplements?
Often yes, but check that you are not exceeding the daily intake of any nutrient across everything you take. If you are unsure, ask a pharmacist.


Food supplements should not replace a varied, balanced diet and a healthy lifestyle. Do not exceed the recommended daily intake. Keep out of reach of children. If you are pregnant, breastfeeding, taking medication or have a medical condition, speak to your doctor before use.
