If you are researching collagen peptides in Canada, you may be comparing powders, capsules, marine or bovine collagen, possible skin and joint benefits, and how to identify a properly licensed Canadian product.
Collagen peptides are hydrolyzed fragments of collagen protein designed for oral consumption. Unlike experimental injectable peptides, licensed oral collagen peptide products can legally be sold as natural health products in Canada.
What Are Collagen Peptides?
Collagen is a structural protein found throughout connective tissues such as skin, cartilage, tendons and bone. Collagen peptides are produced by hydrolyzing collagen into smaller peptide fragments. You may also see products described as hydrolyzed collagen or collagen hydrolysate.
Collagen peptide supplements are commonly sold as powders, capsules, liquids and gummies. Their source can vary, including bovine, porcine and marine collagen.
What Are Collagen Peptides Used For?
Skin Research
Human trials have studied oral hydrolyzed collagen for skin hydration, elasticity and visible signs of skin aging. A 2023 systematic review and meta-analysis included 26 randomized controlled trials and 1,721 participants. It reported improvements in skin hydration and elasticity compared with placebo, while also identifying bias in the available studies and calling for larger trials.
Joint and Cartilage Research
Collagen supplements have also been studied for joint health. Some licensed Canadian collagen products carry authorized uses related to osteoarthritis-associated joint pain.
Hair and Nails
Some licensed formulations in Canada have authorized claims related to healthy nails or hair strand thickness. These claims apply to the specific licensed product and formulation, not automatically to every collagen powder.
What Results Have Researchers Studied?
Research has measured outcomes including skin hydration, elasticity, wrinkles, joint discomfort and physical function. Results vary by formulation, dose, study length and population.
Collagen supplements should therefore be judged by evidence for the specific use and formulation rather than broad claims that every collagen product produces the same result.
Collagen Peptides vs Regular Collagen
Collagen peptides are hydrolyzed collagen. The hydrolysis process breaks the larger collagen protein into smaller peptide fragments. Gelatin is also derived from collagen but has different processing and physical properties.
Are Collagen Peptides Legal in Canada?
Yes. Health Canada licenses natural health products containing hydrolyzed collagen. Licensed products receive an eight-digit Natural Product Number (NPN), which lets Canadians verify that Health Canada has authorized the product for sale under the Natural Health Products Regulations.
The federal Licensed Natural Health Products Database contains multiple active collagen peptide licences, including oral powders and other formats containing hydrolyzed collagen.
How to Choose Collagen Peptides in Canada
Check the NPN
Look for an eight-digit NPN on a Canadian natural health product and verify it in Health Canada’s Licensed Natural Health Products Database.
Check the Collagen Source
Determine whether the collagen is bovine, marine or another source, especially if you have dietary preferences or allergies.
Compare the Amount Per Serving
Products vary widely in the amount of hydrolyzed collagen supplied per serving. Compare the medicinal ingredient panel rather than scoop size alone.
Check Added Ingredients
Some formulations include vitamin C, biotin, hyaluronic acid, flavours or sweeteners. These can change the product’s authorized claims, nutritional profile and suitability for you.
Looking for Collagen Peptides in Canada?
We are building our Canadian product directory. Tell Peptides Canada what type of collagen peptide product you are looking for and we can use your request to help identify relevant Canadian options.
Collagen Peptide Safety
Follow the directions and risk information on the specific licensed product. Health Canada product licences show that some collagen formulations may cause mild gastrointestinal discomfort and may include additional cautions depending on their ingredients and intended use.
People with allergies should check the collagen source and full ingredient list. Product-specific directions take priority because formulations differ.
Collagen Peptides Canada FAQ
Can you legally buy collagen peptides in Canada?
Yes. Licensed natural health products containing hydrolyzed collagen are legally sold in Canada. Look for an NPN and verify the specific product in Health Canada’s database.
Are collagen peptides the same as injectable peptides?
No. Collagen peptide supplements are hydrolyzed protein products consumed orally. They should not be confused with experimental injectable compounds commonly discussed in peptide therapy.
Do collagen peptides help skin?
Randomized trials and meta-analyses have reported improvements in measures such as skin hydration and elasticity. Study quality varies, and results should not be treated as guaranteed for every product.
Are marine collagen peptides better than bovine collagen?
They come from different sources and can have different collagen profiles. The best choice depends on the product, intended use, dose, dietary preference and evidence supporting the specific formulation.
How do I know if collagen peptides are approved for sale in Canada?
Check the package for an eight-digit NPN and search that number in Health Canada’s Licensed Natural Health Products Database.

Research Collagen Peptides Before You Buy
Collagen peptides are one of the peptide categories Canadians can purchase as licensed consumer health products. Check the NPN, collagen source, dose, ingredients and authorized claims before choosing a product.
