Why Do People Take Collagen?

Collagen is the most abundant protein in the body, making up around a third of its total protein. It's the main structural protein in skin, bones, tendons and cartilage, and the body's own production slows as we get older.

Collagen supplements are made from hydrolysed collagen peptides: collagen broken down into small chains of amino acids such as glycine, proline and hydroxyproline so it dissolves easily in a drink. Most people take them as part of a daily routine alongside a balanced diet.

What a collagen supplement can and can't promise

In Great Britain, supplements can only make health claims that are on the government's approved register. Collagen itself has no approved claims, so be wary of any brand that promises to remove wrinkles or fix joint pain. Here's what can be said:

  • Protein contributes to the maintenance of muscle mass and to the maintenance of normal bones. A high-protein collagen powder like our top pick (12.6g protein per serving) counts towards your daily protein.
  • Vitamin C contributes to normal collagen formation for the normal function of skin, bones, cartilage and blood vessels.
  • Biotin contributes to the maintenance of normal hair and skin, which is why some people pair collagen with a biotin supplement.

How We Score Collagen Supplements

Every product gets a score out of 10 for 5 criteria. Each criterion is weighted by how much it matters to someone buying collagen, and the weighted scores add up to the overall score you see on each review. We base scores on the product label, the brand's list price, delivery terms and verified customer reviews. The letter grade follows the score: A+ is 9.5 or more, A is 9.0, B+ is 8.0, and so on.

What To Look For

Four things separate a good collagen supplement from an expensive one.

✓

A full dose in one serving

Most published studies use 2.5g to 15g of collagen peptides a day. Check how many grams of collagen you get per serving, not per pack. Capsules often contain under 1g each, so you'd need a handful a day to match one scoop of powder.

✓

Hydrolysed peptides, Type I & III

"Hydrolysed" means the collagen has been broken down into peptides that dissolve easily. Type I and Type III are the main types found in skin. Bovine collagen provides both, and marine collagen is mainly Type I.

✓

A short ingredients list

The best powders list one ingredient: collagen peptides. Sweeteners, flavourings and sugars add cost and make the powder harder to use in savoury food or coffee. Better filtering also means less smell and taste.

✓

Price per serving, not price per pack

A cheap tub with small servings can cost more per day than a bigger one. Divide the price by the number of full servings. Across our top five, the price ranged from 57p to £2.43 per serving.

What to avoid

  • "Vegan collagen". It doesn't exist. These are plant blends with no collagen in them.
  • Gummies and capsules that give you a fraction of a gram per serving.
  • Miracle claims like "erases wrinkles" or "cures joint pain". These claims aren't permitted in the UK.
  • Unknown marketplace sellers with no UK address or ingredient details.

Thirty Seconds to Spot a Good Collagen Label

Turn the pack over before you buy. The front sells the product; the back tells you what's in it.

Good signs

  • Grams of collagen per serving, not per pack
  • One ingredient: hydrolysed collagen peptides
  • The collagen type and source (bovine or marine)

Walk away

  • A dose in milligrams, or several capsules for one serving
  • Sweeteners, sugars or flavourings near the top of the list
  • Promises about wrinkles or joint pain, which aren't permitted in the UK

Pros

  • Best value we found: 57p per 14g serving
  • 14g serving sits at the top of the studied range
  • Collagen only: hydrolysed bovine peptides, no additives
  • Triple filtered, so it's virtually odourless and tasteless
  • Over 90% protein (12.6g per serving)
  • Made in the UK
  • Free Next Day Delivery

Cons

  • Only available online
  • Not suitable for vegans or vegetarians
Choose it if you want a full-strength daily dose for the lowest price per serving, and an unflavoured powder you can add to coffee, tea or a smoothie.

Our Verdict

Nutrition Geeks Collagen Glow Up is our top pick because it wins on the two things that matter most in a collagen powder: how much collagen you get per serving and what each serving costs. At 57p for 14g it's cheaper than every other product we compared, and the label is a single ingredient. It's over 90% protein, and protein contributes to the maintenance of muscle mass and normal bones. The only real downsides are that it's online-only and not vegan.

Pros

  • Generous 13g serving
  • Type I & III bovine collagen

Cons

  • Costs more per gram of collagen than our top pick (4.9p vs 4.0p)
  • Delivery costs £2.90 on orders under £30

Choose it if you want a simple UK-made collagen and plan to subscribe or buy several tubs at once.

Our Verdict

Wellgard is a solid, single-ingredient bovine collagen made in the UK, with a generous 13g serving. It loses out to our top pick on price per gram at full price, and on delivery, which costs £2.90 unless you spend £30.

B7.8/10
Rheal Vegan Collagen Support
  • Suitable for vegans

Frequently Asked Questions About Collagen

How much collagen should I take a day?

Most published studies on hydrolysed collagen peptides use between 2.5g and 15g a day. Powders make it easy to reach the higher end of that range in one scoop, while capsules usually need several a day to get close. Always follow the dose on the label.

Is marine or bovine collagen better?

Both are mainly Type I collagen, and bovine collagen also contains Type III. Bovine collagen is usually cheaper per gram, which is why most good-value powders use it. Marine collagen suits pescatarians. Neither is suitable for vegans.

Is there such a thing as vegan collagen?

No. Collagen only comes from animal sources. Products sold as "vegan collagen" are plant blends of vitamins, minerals and amino acids, and contain no collagen. Vitamin C contributes to normal collagen formation for the normal function of skin, which is why many of these blends include it.

Can I get enough collagen from food?

Bone broth, fish skin and slow-cooked cuts of meat contain collagen, but amounts vary a lot and most modern diets include little of them. A powder gives you a measured amount each day.

When is the best time to take collagen?

Any time of day. Consistency matters more than timing, so most people add it to the same drink every morning, such as coffee, tea or a smoothie. Unflavoured powders are easiest to fit into a routine.

Can you take too much collagen?

Collagen is a protein and there's no set upper limit, but stick to the dose on the label. Some people notice mild fullness or bloating at high doses. If you're pregnant, breastfeeding, taking medication or have a medical condition, speak to your GP or pharmacist first.
