Collagen Low Dalton: What Molecular Weight Means for Collagen Peptides

How long does it take to notice a difference?

Trials generally measure skin changes over weeks, not days. The 2018 study above assessed participants at 6 and 12 weeks. Results vary, and some people notice no change.

Does it matter what you mix it with?

It may, though evidence is limited. One human study found that taking collagen peptides with yoghurt raised blood levels of several collagen-derived peptides compared with water. That was a single study using a different product, so treat it as an interesting lead rather than a rule.

Who should check with a professional first?

Anyone who is pregnant or breastfeeding, takes regular medication, has a food allergy or has a medical condition should speak to their GP or pharmacist before starting a supplement. Bovine collagen is not suitable for vegetarians or vegans.
