Vida Glow

Smaller fragments, faster uptake. Ordinary hydrolysed collagen is broken into peptides of varying lengths that the gut breaks down further. Tripeptides, three amino acids long, are the fragments that appear in the blood after collagen is eaten and that signal fibroblasts to make new collagen. Pro Collagen+ supplies them directly, which is the basis of the brand's five-times-stronger claim.

Tested, with numbers. Vida Glow publishes the results of its studies as percentages and timeframes, 42% fewer wrinkles in 21 days in the 2024 Pro Collagen+ study, rather than adjectives. The study is brand-funded and, at the time of writing, awaiting publication, which is the honest caveat.

Sourced responsibly. Collagen comes from the skin of open-water farmed fish in Europe, from suppliers certified by the Aquaculture Stewardship Council, Best Aquaculture Practices and Global G.A.P.

This is a supplement, not skincare. It works through nutrition, alongside your topical routine rather than instead of it. Daily use for eight to twelve weeks is where the study effects sit; a sachet now and then will not show much.

Flavourless and heat-stable. Pro Collagen+ goes into coffee, tea or water without changing the taste, which is most of the reason people keep taking it.

Who should check first. Fish allergy rules it out. Pregnant or breastfeeding, speak to your practitioner before starting any supplement. Not suitable for vegetarians or vegans.
