Filter the shelf
Products are only meant to appear when the catalog lists at least 8g protein and fewer than 180 calories per serving.
About 180cal
A tighter way to shop protein.
Most marketplaces make you compare calories, protein, serving size, and availability one tab at a time. 180cal starts with one nutrition constraint first: at least 8g protein and under 180 calories per serving.
The storefront filters products before they reach the shelf, then lets shoppers build a shortlist before opening Amazon for checkout.
Constraint first
Every product is intended to clear at least 8g protein and under 180 calories per listed serving.
Profile aware
Height and weight can shape product priority when shoppers choose to save a profile.
Amazon handoff
180cal keeps discovery and cart planning lightweight, while final purchase actions happen on Amazon.
How the storefront works
Built for fast snack comparison, not vague nutrition browsing.
Keep comparison fields close
Each product page keeps the nutrition facts, Amazon ASIN, serving assumption, source labels, ingredient notes, and reviewed date together.
Personalize without blocking
A saved height and weight profile can influence product priority, but browsing and Amazon handoff still work without an account.
Hand off to Amazon
180cal supports discovery and cart planning. Live seller, price, delivery, returns, and checkout decisions happen on Amazon.
