Our Story
We built Stack because we were tired of guessing
Supplements shouldn't be one-size-fits-all. Yet the industry has spent decades selling generic multivitamins — broad-spectrum pills designed for no one in particular. You take them hoping something sticks. That's not health optimization. That's a coin flip.
The problem with generic multivitamins is simple: your body isn't generic. Your nutrient needs depend on your diet, lifestyle, health goals, genetics, and what's actually happening in your bloodstream. A 25-year-old marathon runner and a 50-year-old desk worker shouldn't be taking the same thing.
Stack takes a different approach. We start with a detailed health assessment — a quiz that maps your goals, lifestyle, diet, and health history. From that data, our AI builds a supplement stack tailored specifically to you. Not a category. Not a persona. You.
For those who want to go deeper, we offer optional blood testing through our partnership with SiPhox Health. A simple at-home test measures key biomarkers, and we use that data to refine your stack with clinical precision.
Two phases. One goal.
Phase 1
Quiz-Based Stack
Take the health assessment. Get your personalized stack recommendation in minutes. We ship your first month immediately — no waiting, no blood draw required. This is your data-informed starting point.
Phase 2
Blood-Enhanced Stack
Add the optional SiPhox blood test. In about 10 days, we'll have your biomarker data. Your stack gets refined — supplements adjusted, doses dialed in, new additions if the data calls for it. This is precision.
Precision over personalization.
Evidence over marketing.
What We Stand For
Three pillars. Zero compromises.
Evidence-First
Every recommendation is grounded in peer-reviewed research. We don't follow trends — we follow the data.
Radical Transparency
You'll know exactly what's in your stack, why it's there, and what the research says. No proprietary blends. No hiding behind labels.
Nothing More, Nothing Less
We only include what your body actually needs. No filler ingredients, no "just in case" additions. Precision means restraint.
