🔬 Study Buddy is our ongoing series where we read the actual peer-reviewed research behind supplement ingredients and translate it into plain language, including the less flattering parts. This first post covers what a peer-reviewed study is, how to read one, and the four questions that filter out most supplement marketing.
Most supplement marketing leans on two things: science-sounding language and pictures of attractive people. Sometimes there's a study cited. Often there isn't. When there is, it's usually a single small trial that got a press release and no follow-up.
We thought we'd try something different.
Study Buddy is our ongoing series where we sit down with the actual peer-reviewed research behind the ingredients in our All-In-One Greens and translate what it says into something you can use. Not what the marketing says. Not what someone on TikTok said. What the research actually shows, including the parts that are less flattering than we'd like.
This first post is the groundwork. What a peer-reviewed study is, how to read one without falling asleep, and what to watch for when someone tells you "studies show" anything.
Why We're Doing This.
The supplement world has a noise problem.
There's so much information out there, and so much of it sounds like marketing dressed up in science clothing. Words like "clinically proven," "research-backed," and "scientifically formulated" get thrown around with very little behind them.
The thing is, real research does exist. There are thousands of well-designed studies on the ingredients we use, and a lot of them are genuinely interesting. They're also dense, technical, and written for other scientists. Which means most people don't read them. Which means the marketing wins by default.
We want to change that, at least for our small corner of the conversation.
The goal of Study Buddy is not to turn you into a scientist. It's to give you enough context that the next time someone makes a confident claim about a supplement, you can ask the right question. Where's the study? Who did it? On how many people? For how long?
Those four questions filter out about 90% of supplement marketing.
What a Peer-Reviewed Study Actually Is.
A peer-reviewed study is research that other scientists have reviewed before it got published.
That sounds simple. The detail that matters is the word "before." Peer review is not a friendly thumbs-up. It's a process where independent experts (usually three to five of them, often anonymous) read the study carefully, look for flaws, question the methodology, challenge the conclusions, and decide whether the work is solid enough to publish.
A lot of studies don't make it through. The ones that do have been pressure-tested by people who weren't involved in the research and have no reason to be nice about it.
This is the bar we look for when we say something is science-backed. Not a blog post. Not a podcast clip. Not a quote from a doctor on Instagram. An actual paper that survived peer review and got published in a credible journal.
How to Read a Study Without Losing Your Afternoon.
Studies have a structure. Once you know the parts, you can skim a paper in 5 minutes and walk away with the gist.
The Abstract.
The short summary at the top. What the researchers were testing, how they tested it, and what they found. If you only read one section of any study in your life, read this one. Most abstracts are 200 to 300 words and tell you almost everything you need.
The Introduction.
The "why we did this" section. The researchers explain the background, reference earlier studies, and lay out the specific question they were trying to answer. Useful for context. Skippable if you're in a hurry.
The Methods.
The "how we did this" section. Who participated (humans or animals, how many, what ages, what sex). What they were given. How much. For how long. How the researchers measured the results.
This is the most important section after the abstract. It tells you whether the study actually applies to you. A study on 22 male college athletes drinking three protein shakes a day for two weeks is interesting, but it might have nothing to say about a 47-year-old woman taking a greens powder for six months.
The Results.
The data. Numbers, charts, statistical tests. You don't need to understand every figure. You just need to know two things: did the thing being tested have a measurable effect, and was that effect statistically significant (which is researcher-speak for "probably not just due to chance").
The Discussion.
The "what does this mean" section. This is where the researchers explain what they think their results suggest, where they acknowledge the study's limitations, and where they compare their findings to other research. It's often the most readable part of the whole paper. It's also where you'll spot honest researchers being honest about what their study did and didn't prove.
What We Watch For.
Not every study is equally reliable. Some are strong. Some are barely worth the paper they're printed on. Here's what we look at before we treat a study as meaningful.
Sample size. Bigger is better, with caveats. A study on 1,000 people tells you more than a study on 10. But 50 well-chosen participants in a tightly run trial can be more useful than 500 loose ones. We pay attention to both the number and the quality.
Who the participants were. A study on 22-year-old male college athletes is interesting if you're a 22-year-old male college athlete. If you're not, the results may not apply to you in the way the headline suggests. We look for studies on populations that actually match the people we're writing for.
Length of the trial. Two weeks is too short for most supplement effects to show up. Six months tells you something real. We weight longer trials more heavily.
Human studies versus animal studies. Animal studies are useful for early research and mechanism (figuring out how something might work). Human studies tell you whether it actually works in people. We lean on human studies for any practical claim.
Funding source. If a supplement company funded a study on their own supplement, that doesn't automatically make the study biased. Plenty of industry-funded research is solid. But it's worth knowing, and we always check.
Meta-analyses and reviews. These are studies of studies. Researchers pool the data from many smaller trials and ask, when you put it all together, what's the pattern? A good meta-analysis is more reliable than any single trial. When we can find one, we lean on it.
Where it was published. Some journals have rigorous standards. Others publish almost anything for a fee. We pay attention to where the work showed up.
The Difference Between a Study and a Claim.
Here's the move you'll see constantly in supplement marketing.
A small study with 20 people shows that ingredient X had a modest effect on outcome Y. The marketing then says "studies show ingredient X helps with Y," and quietly drops the part about it being one study with 20 people that hasn't been replicated.
Both statements are technically true. They are not equally informative.
When we cite research in Study Buddy posts, we'll tell you the size of the study, how long it ran, who was in it, and where it came from. If we lean on a meta-analysis, we'll tell you how many trials it pooled. If we cite a single small trial, we'll tell you why we think it matters anyway, and what's still unknown.
You'll be able to decide for yourself how much weight to give each piece of evidence. That's the whole point.
What's Coming Next.
The next Study Buddy post takes apart a peer-reviewed study on Cordyceps militaris, one of the six functional mushrooms in our formula. We'll walk through what the researchers did, what they found, and what it might mean for the energy and endurance claims you see attached to cordyceps everywhere.
After that, we'll work our way through the rest of the ingredient list. One at a time. Same format. Honest assessments, including the ones where the evidence is thinner than we wish it were.
One Last Thing.
Science is not a stack of certainties. It's a slow, messy, self-correcting process of asking better questions and updating what we believe.
The goal of this series is not to convince you that the ingredients in our greens are magic. (They're not magic. Nothing is magic.) The goal is to show you the real research, in plain language, and to trust you with what it says.
If you've ever looked at an ingredient label and wondered what any of it actually does, this is the series we wrote for you.
