Bettervits Collagen Complex is an easy two-capsule routine with added vitamin C, biotin and hyaluronic acid. But capsules can only hold a small amount of collagen, and Bettervits doesn't state how much is in a serving. Nutrition Geeks gives you 14g of collagen a day for 57p, against £1.17 a day for the capsules. Choose Bettervits only if you'd rather swallow capsules than mix a powder.

Or shop BettervitsCollagen 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.
Four things separate a good collagen supplement from an expensive one.
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" 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.
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.
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.
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:

Most published studies on collagen peptides use 2.5g to 15g a day. A capsule holds well under a gram of powder, so two capsules can't come close to a 14g scoop, and Bettervits doesn't give the figure.
Both packs last 30 days. Nutrition Geeks is £16.99 and Bettervits is £35 at its one-off price, so the capsules cost about twice as much per day for far less collagen.
Both deliver free. Nutrition Geeks arrives the next day; Bettervits estimated two to four days when we checked.
Bettervits adds vitamin C, which contributes to normal collagen formation for the normal function of skin, plus biotin, vitamin E, hyaluronic acid and turmeric. Nutrition Geeks is collagen only.
Capsules need no mixing and have no taste. A powder takes a few seconds to stir into a drink.
Capsules are convenient, but each one holds well under a gram of powder. Most published studies use 2.5g to 15g of collagen a day, which is far easier to reach with a scoop of powder than with capsules.
Bettervits doesn't state the amount of collagen per serving on its product page. The serving is two capsules a day, alongside vitamin C, vitamin E, biotin, hyaluronic acid and turmeric.
Both last 30 days. Nutrition Geeks costs £16.99 (57p a day) and Bettervits costs £35 (£1.17 a day) at their one-off prices.
Yes. Vitamin C contributes to normal collagen formation for the normal function of skin, so some people take it alongside collagen. Check the labels so you don't exceed the recommended amounts.
