a16z longevity report surveys 500 Americans on health trends, from peptides to microplastics

The a16z report, based on a survey of 500 randomly selected U.S. consumers, argues the longevity movement went mainstream due to the pandemic and ChatGPT. Survey findings include 63% awareness of microplastics, 70% filtering water, 62% willing to pay more for non-toxic products, and 54% using wearables. The authors see opportunities in a "healthcare home" app, FDA-regulated peptide drugs, and cholesterol management, noting compounded peptides remain unapproved while tirzepatide generated nearly $44 billion in nine months of 2026.
