Ever scroll past a “miracle ingredient” and wonder ...“does any of this actually work”?
I’m Marianna Khanivetskaya, a biomedical scientist and chemist, here to unpack the real science behind wellness trends. From skincare to supplements and TikTok hacks to “biohacks,” I break down what’s proven, what’s hype, and why some things work while others just sound good.
Real facts, real context. No pseudoscience.
Creatine has officially rebranded. What used to be a dusty bodybuilding supplement is now a full-blown wellness product, sold for brain fog, focus, and “feeling better”. But as creatine has moved into the mainstream, it’s also started showing up in pastel packaging and forms that don’t always deliver what they claim.In this episode, I break down what creatine is, how it works, and what the evidence really shows when it comes to strength, memory, and cognitive benefits. I look at why creatine affects your muscles and brain differently, what the clinical data actually shows on cognitive effects, and why dosing and context matter far more than most people realise.I also unpack why results can feel inconsistent, why certain formats raise more questions than answers, and why some of the longest-standing concerns around creatine have managed to stick around despite the evidence.If you’ve come across creatine recently or seen the hype around creatine and thought, “Is it just another supplement having a very good marketing moment?”, this episode will give you everything you need to know about it, without oversimplifying what’s actually a more nuanced picture.https://www.instagram.com/forsciencessake_https://www.tiktok.com/@forsciencessakehttps://x.com/forsciencessake

You’re Probably Using Red Light Therapy Wrong
Red light therapy has become one of the most polarising tools in the wellness space. Some people dismiss it as expensive LEDs and clever marketing. Others treat it like a universal fix for skin, pain, recovery, and everything in between. Yet the results people report are wildly inconsistent, even among those using similar devices.
In this episode, I look at why red light therapy has ended up in this strange place, why the same claims can sound both convincing and questionable, and why people approaching it with equal enthusiasm can walk away with completely different results. We’ll look at what the research actually measures, how those findings are often interpreted, and where those interpretations start to drift.
If you’ve ever considered getting a red light therapy device and thought “Does this actually work?” or tried it and wondered “…or am I just doing it wrong?” , this episode will give you a clearer way to think about it. One that finally makes sense of the noise, without the hype.

Collagen Supplements: Do They Actually Work?
Collagen is taken by millions of people: mixed into coffee, added to smoothies, treated like a long-term investment. And yet no one seems to agree on whether it actually does anything.
In this episode, I look at how collagen is absorbed, why where it comes from, how much you take, and how long you stick with it matter far more than most people realise. I also unpack why results around collagen feel so inconsistent from person to person, and why expectations around it tend to run way ahead of what it can realistically deliver.
If you’ve ever taken collagen and thought “am I doing this wrong… or is it even worth it...?”, this episode will change how you think about it.

Retinol is everywhere, but almost no one understands what it actually does, and most people are using it wrong. In this episode, I break it down: how one molecule shapes yourvision, immune system, and skin, and why it became the internet’s favourite anti-ageing ingredient. I walk through how retinoids truly work, why irritation happens, and the practical way to use them without compromising your skin barrier.
If you’ve ever wondered why your “glow routine” sometimes backfires, this is your science-first explanation.
