Visit the shopHow we write and check our content
Based on published sources
Our articles draw on published studies, health organisations and manufacturer safety guidance, and we link to sources where we can.
Careful with health claims
We describe what research suggests without overstating it, and we point out when evidence is limited or mixed.
Information, not medical advice
Our content is general and educational. Please talk to a doctor before starting, especially if you are pregnant, have a heart condition or take medication.
Kept up to date
We review and update articles over time. If you spot something wrong or out of date, let us know and we will look into it.
How the site is funded
Light Life is free to read. We cover our costs through advertising and affiliate links on our shop pages, which may earn us a small commission at no extra cost to you. This never changes what we write about a product or therapy.
We also run sister sites for readers in the United States and Australia, so some general guides appear in more than one place.
