How we evaluate brands and products

At Health Protocol we aim to give you honest, useful guidance. Here's how our reviews and rankings are produced.

Our process

• We research each product using reputable, published sources.
• Where possible, we test products hands-on over a meaningful period.
• We assess effectiveness, ingredients/specs, value, and user experience.
• Ratings reflect our overall assessment against these criteria.
