Collagen powder is sold with a great deal of promise attached to it. This article makes none. What follows is what is physically in the tub, how to read the label, and how to work out whether one is better value than another, because those are the questions a shop can actually answer.
Whether a supplement is right for you is a question for a doctor or a pharmacist, not for us.
What it is
Collagen is a protein. The powder sold in tubs is hydrolysed collagen, sometimes called collagen peptides, which means the protein has been broken into shorter chains so it dissolves in liquid instead of setting into jelly.
Most of it is made from bovine hide. Marine collagen, made from fish, also exists. The good products have one ingredient on the back and nothing else.
Reading the label
Four numbers tell you nearly everything.
- Serving size. This varies enormously between brands and it is the number that makes comparison difficult. Ten grams and twenty grams are both common.
- Collagen per serving. Should be close to the serving size if the product is pure. If a 10g scoop contains 6g of collagen, something else is in the tub.
- Servings per container. Net weight divided by serving size. Worth checking, because the front of the pack advertises weight and the back advertises servings.
- Ingredients. A single line is a good sign.
Why tubs are hard to compare
Two products we stock make the point. One uses a 10g daily scoop and holds 250g, giving 25 servings. Another uses a 20g scoop and holds 284g, giving about 14. The second tub is heavier and has fewer servings in it.
So compare on cost per serving, not cost per tub and not cost per gram. Divide the price by the number of servings on the back of the pack. That is the only figure that reflects what a month actually costs you.
We put the serving count and the collagen per serving in the description of every supplement we list, so you can do that arithmetic without opening the box.
Halal, kosher and sourcing
Because most collagen is bovine, sourcing matters to a lot of people in Uganda. Halal certification is not a default; it is a specific certification that appears on the pack, and a product without the mark should not be assumed to carry it.
Other marks you may see are about different things entirely. Grass-fed and pasture-raised describe the cattle. NSF Certified for Sport means the batch has been tested for substances banned in competition, which matters if you are a tested athlete and is otherwise a sign of batch testing.
How people take it
Unflavoured collagen dissolves in hot or cold liquid and is close to tasteless, which is why it is usually stirred into tea, coffee, porridge or juice rather than drunk on its own. Stir while you pour to avoid lumps.
Follow the serving on the pack. More is not a strategy.
Two honest cautions
First, collagen is an incomplete protein. It does not contain all the essential amino acids, which is why reputable packs say in small print that it supplements a balanced diet rather than replacing dietary protein. Some print it as a formal notice.
Second, check the allergen line. Several are made in facilities that also handle milk, fish and tree nuts, and that is stated on the back.
If you are pregnant, breastfeeding, taking prescription medication or under medical supervision, speak to a doctor before starting any supplement. Products of this kind are not suitable for under-18s.
