I'm Alex. I started reading supplement research the day I realized my cabinet of pills cost more monthly than my groceries - and that I couldn't explain what half of them actually did.
Nutri Grader's method is boring on purpose: read the label, check what peer-reviewed research supports at what doses, verify third-party testing, and grade accordingly. The marketing story never enters the grade.
One thing we are not: doctors. Nothing here is medical advice - supplements can interact with medications and conditions, so run any changes past a healthcare professional who knows your history.

We sign up for and actively use every tool we write about. Each product is scored across four pillars — ease of use, features, value for money, and support — each rated from 1 to 5. The overall score is the average of those four numbers, always on a clear 5-point scale.
Some of our links are affiliate links, which means we may earn a commission when you sign up through us. This funds our testing. It never influences a score or ranking — a low-scoring tool with an affiliate program still gets a low score. You will find tools rated below average on this site, on purpose.
