How it works
Supplement research, structured.
Evellan turns scattered product pages into one comparable format — so choosing a supplement takes minutes, not evenings.
Three focused steps
From scattered tabs to a clear shortlist.
Choose a step to begin, or follow the full process from search to shortlist.
- 01
Search
Search by product, ingredient, brand, or category. Every listing is normalized into the same structured format, so results are directly comparable from the first click.
Search the marketplace - 02
Compare
Select up to five products and see them side by side: price per serving, ingredient amounts, formats, certifications, testing, and reviews — with the meaningful differences called out.
Start a comparison - 03
Choose
Set shopping preferences like budget, format, and testing requirements. Matching products explain exactly why they fit — and the alternative finder shows what you would trade off.
Build your shortlist
Product scoring
A transparency score you can audit
Every product gets a 0–100 shopping-transparency score computed from listed data. It is not a health or efficacy rating — and every point is explainable.

How we verify products
Badges are earned with documentation and review — they can't be purchased, and organic recommendations can't be sponsored.
Verified Brand
The company completed identity and business verification with our team.
Product Information Verified
Listed ingredients, amounts, and serving details were checked against the product label.
Third-Party Tested
Independent lab testing documentation is on file and reviewable.
Certification Verified
Claimed certifications (NSF, Informed Sport, USDA Organic…) were confirmed with the certifier.
This demo runs on a fictional catalog; badges shown illustrate the verification system.
Where the AI fits — and where it doesn't
The shopping assistant compares listed product data: prices, servings, ingredients, formats, and testing. It explains its reasoning, and its recommendations can't be bought by brands. It does not diagnose, prescribe, or make health claims — for medical questions, always consult your physician or another qualified healthcare professional.
