Our Process

How We Review Every Supplement

01

Research the Formula

We analyse every ingredient against published research — PubMed, Cochrane, clinical trials. Marketing claims are separated from actual evidence.

02

Verify Doses

We compare label doses to clinically published effective doses. Underdosed formulas get flagged regardless of how well they're marketed.

03

Assess Safety Profile

Drug interactions, contraindications, and safety warnings are disclosed in every review — even when the manufacturer omits them.

04

Give an Honest Score

Every supplement is scored 1–10 on ingredient quality, dose transparency, guarantee, value, and user feedback. We score honestly — including cons.
