I’ve been formulating a gut health product for eight months. Two months stuck in regulatory delays. Before this, I spent eight years in food tech strategy, working on revenue models and pricing psychology for brands I won’t name here.
I thought I understood the supplement industry.
I didn’t understand shit.

The First Thing I Learned: I’d Been a Sucker
Month two of formulation, I’m reading ingredient labels differently. I stopped caring about promises. I started calculating manufacturing costs.
Gut health supplements that taste like candy. Protein powders with thirty ingredients when they need five. “Proprietary blends” that let brands hide actual doses behind marketing copy.
I kept asking myself: why does everything designed to fix digestion include ingredients that make digestion worse?
Then I learned about gummy supplements. 20 to 30% active ingredients. The rest? Sweeteners, gelatin, fillers. Tablets run 50 to 60% fillers.
The protein powder I’d been using for two years? I learned manufacturers spike products with cheap amino acids to game nitrogen tests. Less actual protein than the label claims.
I’d spent thousands of dollars on premium supplements. Third-party tested. Clean labels. GMP certified.
I’d been paying for filler.
The Second Thing: My Gut Wasn’t Broken
Month four. I’m testing formulations on myself because that’s what you do when you’re building something and regulatory approval is still months away.
I cut out everything I’d been taking. The protein powder. The probiotics that tasted like dessert. All the supplements with ingredient lists I could barely pronounce.
Three days later, the bloating I’d been living with for two years stopped.
The afternoon crashes where I’d need coffee just to function? Gone.
Turns out my gut wasn’t broken. I was just feeding it science experiments designed to keep me buying more science experiments.
Your gut is an ecosystem. Bacteria break down what you eat into things your body can actually use. When that system works, protein becomes muscle. Nutrients get absorbed. Energy happens.
When it doesn’t, protein just sits there. Fermenting. Creating inflammation. Getting wasted.
Recent reviews describe the gut microbiome as a metabolic organ that influences nutrient absorption, metabolism, and gut barrier function. When it’s compromised, you get malabsorption and inflammation instead.
Most gut health products keep you buying. That’s the design.
And I know this because I spent four months looking at the economics.
The Third Thing: The Business Model Is the Problem
Month six. I’m trying to figure out pricing.
A customer who finds a solution and stops buying isn’t valuable. A customer who keeps searching, keeps trying new brands, keeps hoping the next one will work? That’s worth $485 billion in 2024.
The digestive health supplement market alone is already near $18.9 billion as of 2025 and continuing to grow.
I kept thinking: surely someone regulates this.
They don’t. Not really.
In a 2023 JAMA Network Open analysis of sports supplements, 40% had no detectable amount of the labelled ingredient. A 2025 lab analysis published by Niagen Bioscience found that only 5 of 21 Amazon-purchased NAD+ products met label claims. Eleven showed no detectable NAD+ at all.
Nothing fundamentally changed. The industry got better at marketing.
Why would it change? Why would anyone rush to fix a problem that pays this well?
What I Couldn’t Unsee
Month eight. Formula locked. Waiting on regulatory approval.
I couldn’t keep buying supplements designed to keep me searching.
That’s when GUTSY stopped being a formula and became infrastructure.
Protein only works if your gut can process it. Same with nutrients. Everything you’re optimising sits on top of this foundation. If the foundation is broken, nothing else matters.
So we built differently. Proper dosing of digestive support. No common allergens irritating gut lining further. Formulated for consistency because gut health isn’t fixed in 30 days.
Most brands won’t make these choices. They’re expensive. And they work, which means people stop buying.
We made them because I got tired of being the customer who kept searching.
Two Months in Regulatory Hell
That’s where I am now. Two months of delays. The formula works. I know it works because my body works differently now. The bloating that felt normal for years? Gone. The sense that I was doing everything right but my body wasn’t responding? Fixed.
But I can’t sell it yet because paperwork moves slower than gut bacteria.
So I’m writing this instead.
Your supplement stack is probably backwards. All the protein optimisation, all the macro tracking, all the expensive powders only matter if the system processing them actually functions.
That bloating isn’t normal. That exhaustion despite “doing everything right” isn’t just stress. That sense that your body isn’t actually using what you’re giving it?
You’re right.
I spent eight months learning I was right too.
