How it works
Three steps to a confident choice
No twenty open tabs. No squinting at labels. The research, structured.
Step 1 of 3
Search
Find supplements from participating brands — by product, ingredient, or category.
Step 2 of 3
Compare
Compare ingredients, servings, price per serving, testing, and certifications side by side.
Step 3 of 3
Choose
Find products that match your shopping preferences — budget, format, dietary needs.
Compare with confidence
Every product, broken down the same way
Marketplace listings are normalized into the same structured facts panel, so you can put any products side by side and see what actually differs.
- Ingredients & amounts
- Price & price per serving
- Serving count & format
- Certifications
- Third-party testing
- Customer reviews
AI-powered discovery
An assistant for shopping, not a search box
Ask for cheaper alternatives, more servings, or the biggest difference between two products. The assistant works from listed product data and always shows its reasoning.
- Compare any products in plain language
- Find alternatives that match your preferences
- Understand what actually differs between labels
The assistant helps you shop and compare. It never gives medical advice.

We'll organize the label details into a clear side-by-side.
Demo preview — link analysis uses simulated extraction for now.
Trust
How we verify products
The marketplace is built around transparent product information — badges are earned with documentation, never bought.
Verified brands
Brands complete identity and business verification before listing.
Label-checked information
Listed ingredients and amounts are checked against product labels.
Testing on file
Third-party testing badges require reviewable lab documentation.
This demonstration catalog is fictional — product imagery and brand logos are placeholders, and verification badges here illustrate how the trust system works.
