Collagen supplements, without the overclaiming

What collagen supplements actually are

Collagen is a structural protein your body makes. Supplements are made by taking collagen from an animal or marine source and hydrolysing it, which breaks the long chains into much shorter peptides. That is what makes a collagen powder dissolve into coffee instead of turning into gelatin.

Once swallowed, hydrolysed collagen is digested much like other dietary protein. The open research question is whether the resulting peptides and amino acids influence the body’s own collagen production in a way that produces a noticeable result, and that is genuinely not settled.

How to check a claim rather than trust it

This is the most useful thing on this page, and it works for any supplement sold in Canada, mine included.

• Find the NPN, an eight-digit Natural Product Number, on the label.
• Look it up in Health Canada’s Licensed Natural Health Products Database, linked in the sources below.
• Read the "recommended use or purpose" field. That is the claim Health Canada actually licensed. Anything a seller says beyond it, including anything I might say, is not covered by that licence.

If a product has no NPN, it has not been licensed for sale as a natural health product in Canada. That on its own is worth knowing before you buy.

Powder or liquid

This is mostly a practical question rather than a scientific one. Powder is cheaper per serving and mixes into whatever you are already drinking. Liquid formats are pre-measured and easier to keep up with, which is not a small thing given that consistency is the part most people fail at.

If you are going to forget a scoop every second morning, the more expensive format you actually take is the better buy.

What I will and will not tell you

I will tell you what is in the tub, what it is licensed for, what it costs per serving, and what customers report. I will not tell you it will change your skin, because I do not know that and neither does anyone selling it to you with confidence.

Collagen is also protein, so if you are buying it purely as a protein source, compare it on grams per serving against the options on my protein page. It usually loses that comparison on price, and that is worth knowing before you spend.
