Sometimes, the most profitable SaaS ideas don't come from brainstorming sessions or studying MRR charts. They come from staring at your own medicine cabinet in pure frustration.
As a builder, I despise inefficiency. Recently, I fell down the health supplement rabbit hole. I spent countless hours researching what to take, only to be met with a wall of conflicting information. Should I take Supplement A with B? Will they cause a bad reaction together? Does C cancel them out?
It was an incredibly complex and frustrating experience. But then, the founder instinct kicked in.
The Overwhelm is the Opportunity
Where there is massive data complexity surrounded by clashing information, there is a vast business opportunity. I realized that if I was this overwhelmed, millions of others—and more importantly, the wellness professionals trying to guide them—must be too.
People will gladly pay to turn data chaos into absolute clarity. So, I stopped researching and started coding.
Cutting Through the Noise with Data
I decided to build Vitabase—an AI recommendation engine built on top of a massive, heavily vetted database of supplements, drug interactions, and medical data.
The UX is dead simple: A user inputs their basic data (gender, age, body mass, and habits like smoking or coffee intake), and the engine analyzes the cross-interactions to spit out a highly personalized, clinically accurate recommendation matrix. No more guesswork.
Taking the First Step (The Architecture)
This is no longer just an idea. I've already started piecing together the core architecture. But getting an AI to parse complex medical data without hallucinating or crashing requires a very specific logic flow. It's far beyond a simple ChatGPT wrapper.
Since I don't want to turn this Indie Hackers post into a massive wall of technical documentation, I’ve detailed the initial system architecture, the database structure, and my exact roadmap on my personal blog.
If you're curious about how I'm structuring the backend to handle this kind of data load (and turning my frustration into a product), you can read the full technical breakdown here:

Hi Kevin Jang, Vitabase is at an ideal starting point for the record: you have named the personal frustration, begun coding, and published the first technical build log. I’m building Build Before 2030: a manually reviewed public record where makers claim a Founding 100 number, set one measurable 30-day milestone, and later add proof of what shipped. The first cohort is free. Vitabase feels like a strong fit. Interested? https://buildbefore2030.com
