About Liam

My name is Liam Kratos. I read the research behind the things being sold to you, and I write down what it actually says. Including, and especially, when that means something does not work.

The training behind it

Natural nutrition, aromatherapy, herbal medicine, orthomolecular therapy and orthomolecular nutrition, all five completed at Dutch higher professional education level. I keep learning every day, because the research does not stand still either.

Why this site exists

Knowledge about your own body should be free. Not free as bait for something else. Just free, so anybody can live well and spend their attention on what they actually want to do, instead of on working out who is lying to them.

There is a second half to it. The best products and the best food there is, at the lowest price we can make it. We would rather earn something small in the open than something large quietly, and what we earn we write down.

And the reason any of this is needed: almost everybody who ends up here has already bought something that did nothing. A supplement after a reel, a posture corrector, an expensive stack. That money does not come back. What is left is caution, and caution is the thing this site is trying to answer.

How the research here is read

Every analysis starts with a PubMed search that I print alongside it, so you can run it again yourself. I read research in people, not cell cultures and not mice, unless I say explicitly that is what a finding rests on.

Null results get the same space as positive ones. If I cannot trace a claim to a published, indexed source, I do not make the claim.

How bad are sugary drinks, and how do you drink one least badly?

In trials where adults were given one sugary drink a day on top of their normal diet, they gained 0.83 kg. Taking one a day away gave half a kilo back. And when you do have one, what is already in your stomach decides how big the sugar spike is.

Is chewing gum bad for you? What your body thinks is coming

The worry is that chewing gum makes your body release insulin as if food were coming, which would matter if you are fasting. Chewing does send that signal, with saliva and gut hormones. When researchers measured the insulin, it had not moved.

Why third-party testing matters

Independent lab testing is the only practical way to check a supplement contains what its label claims. Published analyses keep finding ones that do not.
