Science Over Marketing
Every score is backed by peer-reviewed research. We don't accept payment for better grades, we don't rely on manufacturer claims, and we certainly don't guess.
The SuppMan Score
Your supplement receives a score from 0-100 based on four key pillars
Transparency
Are all ingredient amounts clearly listed? No proprietary blends hiding dosages?
Clinical Dosage
Effective dose at recommended serving size, considering multi-capsule products and dietary intake.
Bioavailability
Are ingredients in their most bioavailable forms with optimal absorption?
Safety & Purity
FDA compliance, third-party testing, absence of banned substances
Understanding Your Grade
