In this conversation, Chris and Prof John Nolan discuss the measurement and correlation of carotenoid levels, specifically macular pigment optical density (MPOD). They explore the challenges of measuring MPOD directly and the limitations of current clinical devices. They also discuss the correlation between skin carotenoid levels and MPOD, debunking the claim that there is an 8% correlation. Prof Nolan explains that there is a 30-40% correlation between skin carotenoid levels and MPOD, making it a valuable tool for assessing carotenoid status in patients. They also touch on the importance of accurate and validated measurements for making informed clinical decisions. In this conversation, Prof John Nolan discusses the importance of accurate information and scientific evidence in the field of eye care and supplementation. He emphasizes the reproducibility of measurements of macular pigment optical density (MPOD) and the ability to make informed decisions based on these measurements. Prof Nolan also highlights the need for honesty and transparency in the supplement industry, particularly regarding the formulation and certification of products. He calls for a commitment to quality and the use of evidence-based science to benefit patients.
