Nutrition Geeks wins 3 of 5 rounds, WillPowders wins 1, 1 tied
This is a close one: both are clean, grass-fed bovine collagen powders with Type I and III collagen. Nutrition Geeks wins because each scoop gives you 14g of collagen against 10g, it costs less per gram (4.0p against 5.8p), and delivery is free and next day. WillPowders is a good choice if you prefer a smaller 10g serving and a pack that lasts 40 days.

Or shop WillPowdersCollagen 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:
