ReadHow these pages are written
- We do not invent statistics, study results or dosages. Where a number cannot be verified, the point is made qualitatively instead.
- Where the evidence is early, small or mixed, we say that plainly rather than rounding it up to a claim.
- Nothing here says or implies that any food or drink treats, prevents or cures anything.
- Mostly we compare mechanisms and formats rather than brands. Where a page does name competing products, it says at the top that SOLR is one of them, uses only figures each brand publishes on its own site, and writes "not published" wherever a figure is missing, including against SOLR.
- Everything here is general information, not medical advice. For anything specific to you, ask a GP or pharmacist.
If you came here from the product side of the site, the ingredients page sets out what is in a can of SOLR and why.
