How every guide is made
The same four steps for every topic, so you can check our work instead of taking our word for it.
- Step 1
Start from the evidence
Each topic begins with current guidance from national health bodies and government agencies, and with published research where guidance is silent.
What you see: a named sources page in every guide.
- Step 2
Write it plainly
We turn long guidance documents into short steps, checklists and tables you can use at 3 a.m., without changing what the source says.
What you see: numbers and thresholds exactly as published.
- Step 3
Mark where we stop
Every guide separates general education from medical, legal or financial advice, and says clearly when to call a professional.
What you see: “when to call” guidance on every topic that needs it.
- Step 4
Date it and re-check it
Guidance changes. Each guide carries the date it was last checked, and facts that change, like phone lines and rules, are re-checked every year.
What you see: a “last updated” date on every sources page.
Standards we hold every product to
Trust should be checkable. These are the rules a Lumavo guide has to pass before it goes on sale.
- Every factual claim traces to a named, authoritative source.
- Figures and thresholds are quoted as the source publishes them.
- Every guide shows the month it was last checked.
- We never present a source as endorsing us. We cite; we are not affiliated.
- No invented reviews, ratings, customer counts or credentials.
- Health, legal and money topics always say when to get professional help.
