About this episode
What's the latest on Collagen?
The new series of Sliced Bread kicks off with an update on one of the wonder products most-requested by listeners. Presenter Greg Foot first looked at Collagen in 2022 and returns to the subject to find out what has changed in the scientific landscape since then. Could there be new evidence that it really can do what the manufacturers claim: rejuvenate skin, nails and hair - and even help with joint and bone health?
To find out, Greg is rejoined by the expert from that original episode four years ago, dermatologist Dr Emma Wedgeworth, alongside Professor Jayne Tierney from University College London who specialises in reviewing evidence.
Together they do a deep-dive on the latest science, including a new study from one of the brands featured in 2022, Absolute Collagen. Does it stand up to scrutiny?
