<\/p>\nIf you’ve been taking collagen supplements without seeing much difference, you’re not alone. Many popular collagen products may not work as promised, and a leading expert has explained exactly why.<\/p>\n
Professor Mohammad Najlah, Professor of Pharmaceutics and Nanomedicine, told GB News: “Collagen can support smoother, firmer skin, but only in very specific forms.”<\/p>\n
The problem boils down to absorption, according to Professor Najlah. Numerous collagen supplements fail because their molecules are simply too large for the body to take in properly, or they’re not delivered in a stable enough format.<\/p>\n
“Most collagen powders are made of molecules that are simply too big to be absorbed, so they never reach the skin,” he said.<\/p>\n

So what about all those products boasting Type I, II, or III collagen? According to Professor Najlah, it’s largely marketing noise.<\/p>\n
“The idea of ‘the best type of collagen for anti-ageing’ is actually misleading. The ‘types’ of collagen Type I, II, III don’t matter when you ingest them,” he said.<\/p>\n
The reason is simple; once you swallow collagen, your body breaks it all down into tiny peptides, regardless of what type it started as.<\/p>\n
“What does matter is the exact tripeptide sequence and whether your body can absorb and use it,” Professor Najlah explained.<\/p>\n
He added that only specific bioactive tripeptides, delivered in a form that actually survives the digestive process, have been shown to support skin elasticity, hydration and a smoother appearance.<\/p>\n
The real question isn’t whether a product is “better than collagen” but whether your body can actually absorb and use what you’re taking.<\/p>\n
“What makes a meaningful difference are specific, bioactive tripeptides that can support fibroblast activity when delivered in an absorbable form,” Professor Najlah said.<\/p>\n
Many standard collagen products simply don’t offer this level of precision. <\/p>\n
The key lies in advanced delivery systems that protect these specific peptides, so they survive digestion and reach where they’re needed.<\/p>\n
