HealthGuard, a service of NewsGuard, helps you identify trustworthy sources of health news and information as you browse the web — and warns you when you encounter links to sites with unreliable health or medical information. You can think of HealthGuard as a trusty sidekick to keep you away from untrustworthy health advice, and to point you toward more trustworthy sources, as you browse the web.
