Signal 22% of consumers use large language models for health and wellness, 26% among Gen Z

Summary

McKinsey reports that 22 percent of consumers use large language models for health and wellness topics, a share that rises to 26 percent among Gen Z. This sits alongside the wider spread of health technology, as many consumers already track sleep, glucose, and heart health with wearable devices. Younger people are also more likely to look beyond medical professionals for health information, and in a 2024 McKinsey survey 38 percent of Gen Z said they turn to social media for it. The report treats this broadening of information sources as part of the technology that is making more health topics accessible and measurable. For companies, it means that how products are described across digital and AI channels increasingly shapes health-related choices.
