Health research, clearly explained

What really helps? Here is what research knows.

Vitamin D, magnesium, turmeric, fasting, acupuncture, sauna: almost every health topic comes with contradictory headlines and thousands of studies. We read the international research and explain in plain language what it has shown, how certain that is, and which questions are still open. Every statement leads back to its original source.

Freely accessible, independent and without advertising.

For everyone who wants to know exactly

The evidence, honestly graded.

Whether you want to do something for your own health, are supporting someone close to you, or are simply curious: for every substance and every method you will find here where it comes from, how it works in the body, what human studies have measured and which questions research still has to settle.

So that you can see at a glance how solid a statement is, each one carries its grade: established means measured in humans, plausible means supported by a mechanism, animal study or observation, and hypothesis means a link that is likely and still has to be tested.

The big picture

The body does not work in separate parts. We show the connections.

A study usually answers a single question: one substance, one measurement, one group of people. How persistent stress changes the hormone cortisol, what that has to do with inflammation and why the gut plays a part is rarely found in a single paper.

We make these connections — with specialised artificial intelligence that evaluates far more studies than any person could ever read. Every step in a chain carries its evidence, and where a gap remains, it is left open for all to see.
