CBD Dosage Calculator
A health and wellness calculator that determines appropriate CBD dosage recommendations based on body weight, reason for use, and product concentration specifications — designed for a CBD product company to embed on their e-commerce site.
The Challenge
The client had a complex Excel formula sheet that calculated CBD dosages based on multiple factors — body weight, condition severity, product concentration, and administration method. They needed this converted into a customer-facing tool that could be embedded directly on their Shopify store.
The Solution
We built a clean, modern web calculator with an intuitive form interface. Users select their parameters and instantly receive personalized dosage recommendations with clear safety messaging. The app includes input validation and error handling to ensure accurate medical-adjacent calculations.
Results & Impact
The embedded calculator increased average time on product pages by 2.5 minutes and contributed to a 15% increase in conversion rate for the CBD product line within the first month.
Key Features
Body weight-based calculations
Condition-specific dosing
Product concentration inputs
Safety validation checks
Clean medical-grade UI
Embeddable widget design
Project Deep Dive
This project required careful attention to both technical accuracy and compliance. The original Excel calculator used a matrix of dosage recommendations based on body weight ranges, condition types, and product concentrations. While the math was straightforward, presenting medical-adjacent recommendations on a public website required careful safety messaging and disclaimer integration.
We worked closely with the client's compliance team to ensure every recommendation included appropriate safety language, and built in validation checks that flag unusual input combinations. The calculator was built as a self-contained widget that could be embedded on any Shopify product page via a simple snippet, matching the store's existing visual design.
The result was a tool that not only answered the most common customer question — "how much should I take?" — but also served as a powerful conversion tool by keeping customers engaged on the product page and guiding them toward the right product and quantity for their needs.
Technologies Used
"Our customers used to email us asking about dosages. Now they use the calculator on our site and add products to their cart immediately. It's our best-performing page for conversions."
