Certainly! Here's a brief and empathetic response you can use:
"I understand your concerns about the marketing of supplements. However, it's important to recognize that many people turn to healthier lifestyles for deeply personal reasons, often influenced by their experiences. For instance, witnessing numerous cancer cases within a family can be a powerful motivator to explore healthier diet choices. While skepticism towards certain commercial practices is valid, let's also acknowledge the genuine health-seeking journeys that many individuals embark on for the well-being of themselves and their loved ones."
