In a recent segment on Good Morning Britain, Dr. Amir Khan, an NHS GP, addressed the growing popularity of collagen supplements, often marketed as a 'fountain of youth.' He explained that while collagen is vital for skin, hair, and joint health, its production declines with age. Despite claims of miraculous benefits, Dr. Khan emphasized that the scientific evidence supporting these supplements is weak, particularly for skin and hair improvements. He noted that many studies showing positive results are funded by the collagen industry, raising questions about their validity. While collagen supplements may offer modest relief for joint pain, especially in individuals with arthritis, they should not replace a nutritious diet rich in natural collagen sources such as chicken skin and bone broth. Dr. Khan encouraged individuals to focus on lifestyle factors—like maintaining a balanced diet, getting adequate sleep, and avoiding smoking—as more effective means of supporting collagen production. He concluded that while collagen supplements might provide some benefits, expectations should be realistic, and they are not essential for everyone.
