Dr Khan explained that whilst collagen is essential for skin, hair and joints, supplements don't work as advertised."When you take a collagen supplement, your body will break it down," he told host Kate Garraway. "Your gut will break it down into its component parts, which are amino acids."A major study looking at 23 randomised controlled trials initially showed skin improvements, but Dr Khan revealed the shocking truth. "Once they pulled out the studies that were funded by the collagen industry, there was no benefit to your skin, your hair, and your nails," he said.The doctor said supplements might help with arthritis-related joint pain but warned people are missing out on proper nutrition. He recommended natural sources like chicken skin, bone broth, lentils and beans instead.Dr Khan's followers backed his findings, with one saying joint pain had improved but hair hadn't. Another joked: "There's no sat nav directing the collagen supplement directly to your wrinkles!"His final verdict was clear: "If you're expecting collagen peptides to erase wrinkles or transform your appearance... the science simply doesn't support that."READ THE FULL STORY: TV doctor gives collagen 'truth' warning as millions take supplement‌
