The Science Behind Wirecutter's Wellness Picks: What Makes These Brands Different

Wirecutter doesn't just pick products because they're popular or well-marketed. Every recommendation is backed by rigorous testing, scientific research, and expert consultation. Here's what separates Wirecutter-approved wellness brands from the rest—and why these standards matter for your health.

Wirecutter's Testing Methodology

The Process

Before any product earns Wirecutter's approval, it goes through:

• Research phase: 20-40 hours reviewing scientific literature, expert opinions, and existing reviews
• Selection phase: Narrowing 50-100 products down to 10-15 finalists based on criteria
• Testing phase: Weeks or months of real-world use by multiple testers
• Expert consultation: Interviews with doctors, scientists, and industry experts
• Re-testing: Periodic reviews to ensure recommendations stay current

Time investment: 100+ hours per product category

Result: Only the best products make the cut.

What They Test For

• Effectiveness: Does it actually work as claimed?
• Safety: Are there health risks or concerns?
• Durability: Will it last or break quickly?
• Ease of use: Is it intuitive or frustrating?
• Value: Is the price justified by quality?
