Every piece goes through the same process, and the grade you see at the top is the output of it. Here is the whole thing, so you can judge it yourself.
The scale
The three grades
A
Well established
Multiple randomised controlled trials, or a strong systematic review, pointing the same way. The effect is real and we can usually say roughly how big it is.
Example: resistance training improving strength and function as you age.
B
Reasonable
Consistent observational evidence, or small or mixed trials leaning one direction. Worth doing if it is cheap and safe, but do not expect certainty.
Example: earlier and more consistent sleep timing helping daytime alertness.
C
Unproven
Traditional use, mechanism arguments, animal studies, or a couple of small trials that disagree. We include these because you will meet them anyway, and you deserve to meet them labelled.
Example: most single-herb claims advertised on social media.
From question to page
What happens before something gets published
Start from the real question
Topics come from what people actually ask, not from what ranks well in search.
Go to the strongest evidence first
Systematic reviews and trials before blog posts. If a claim only exists in marketing copy, that fact goes in the piece.
Grade it before writing
The grade is assigned against the criteria above, before the piece is written, so the writing cannot talk itself up.
Say the size of the effect
A real but tiny benefit is described as a real but tiny benefit. This is where most health writing quietly cheats.
Flag interactions and cautions
Anything that could interact with common medication, or is not appropriate in pregnancy or for children, is marked.
Revisit when evidence moves
Grades can change. When one does, the piece says what changed and when.
No. It is health education. It does not diagnose, does not replace your doctor, and does not tell you to change any medication. Where something needs a clinician, we say so.
