Collagen: cost per 10 g serving
Collagen is best compared on cost per 10 g of hydrolysed collagen, a typical trial and label serving, because capsule products holding under 1 g each are often several times dearer per gram than powders. One honesty note before you spend anything: there are zero EFSA-authorised health claims for collagen. Enter price, pack contents and serving size below for the real cost.

How the calculation works
We divide the pack price by the number of servings, then scale the cost to a 10 g hydrolysed-collagen serving so powders, sachets and capsules all land on the same scale. We also show the cost per 30 days at one 10 g serving a day, which is the number that makes capsule formats look very different from the front-of-pack price. The 10 g yardstick is a pricing convention drawn from common trial and label servings, not a recommendation to take collagen.
Honesty note: the number of EFSA-authorised health claims for collagen is 0, per the EFSA, Nutrition and health claims register, as of 2026-06-11.

Frequently asked questions
Why price collagen per 10 g serving?
Most published collagen trials use daily servings in the range of 2.5 g to 15 g, with 10 g a common label serving for hydrolysed collagen powders, so we use 10 g as the comparison yardstick. Capsule products often contain only 1 g or less per capsule, which is why they usually work out many times dearer per gram than powder.
Does collagen actually work?
The regulator-grade answer: there are zero EFSA-authorised health claims for collagen, so products promising effects on skin, joints or hair go beyond what UK advertising rules permit. Some trials report benefits, but no claim has passed the EFSA evidence bar. This calculator only tells you the honest price; whether to spend at all is the bigger question, and your GP or pharmacist can help.
Are collagen capsules worth buying over powder?
Usually not on value. A typical capsule holds about 0.5 g to 1 g of collagen, so reaching a 10 g serving can mean 10 to 20 capsules. Run both products through the calculator and compare the cost per 10 g; the gap is often severalfold.
Do marine and bovine collagen cost the same?
Marine collagen is usually dearer per gram than bovine. Both are mostly type I collagen once hydrolysed. The calculator works for either; enter the price and the collagen grams per serving from the label and compare like for like.
