Whether you take 3 supplements or 30, Stack Precision helps you understand what's making a difference.

Taking supplements but not sure what's helping?

Most people build their stack from blog posts and recommendations, then take everything on faith. Stack Precision connects what you take to how you feel so you can see what's actually making a difference.

Already tracking? Get smarter about it.

You're consistent and intentional. But spreadsheets and notes don't find patterns for you. Stack Precision uses AI to surface correlations between your supplements, timing, and daily health scores.

Have genetic data? Go deeper.

Upload your 23andMe, AncestryDNA, or whole genome file and see why certain supplements may work better for your body. Your genetic variants add an explanatory layer to the patterns AI uncovers.

Searching for answers on your own?

Fatigue, brain fog, pain, gut issues. If you've been trying things and not sure what's working, Stack Precision gives you a structured way to track, test, and iterate with your own data.

Track, understand, improve. Repeat.

The more you track, the more patterns AI can uncover. Genetics makes it even sharper.

Use AI to Uncover Patterns

Your private AI assistant looks for patterns between your supplements, timing, and health journals. Ask anything about your data and explore evidence-informed insights tailored to your profile. Add genetic data from 23andMe, AncestryDNA, or a whole genome file for a deeper layer of insight into why your body responds the way it does.

You choose exactly what data AI can see. Your name is never sent.
Responses cite research and evidence tiers, not just opinions.
AI chat setup showing data sharing controls for stacks, journal, and genetics
Cohort details showing supplement dosage ranges and medians
Community Trends showing supplement usage by genetic cohort

See what others with your profile are taking.

Community Trends shows anonymized supplement patterns from people who share your genetic variants. See what they take, at what doses, and how it compares to your stack.

Fully opt-in. Fully anonymized. Always your choice.

65% of people with MTHFR variants take L-Methylfolate. Do you?
I was able to make my genetic test results work for me for the first time with Stack Precision. I identified specific things I can do to improve my daily routine and supplement stack and I'm feeling great!

Jeff Goodman, founder of Stack Precision

I spent years trying to figure out why I felt terrible.

Food intolerances. Chronic pain. Brain fog. Doctors ran standard panels, found nothing, and suggested I manage stress better. When I finally dug into the genetic data I already had and started mapping my variants to supplements, things changed measurably.

Stack Precision is the tool I wished existed when I was still guessing. I have 20+ years in tech across startups and Fortune 200 companies. I built it because I know what it feels like to have answers hiding in data that nobody is helping you read.
