On October 14, Consumer Reports published testing showing some popular protein powders contain lead levels 15x over California's safe limits. Naked Nutrition (7.7 µg), Huel (6.3 µg), and several others got "AVOID" ratings.
I was using one of the contaminated brands daily. Spent the weekend analyzing the data and built this tool to help people:
- Check if their current brand is safe
- Find verified-clean alternatives based on their needs
- Understand the Consumer Reports rankings
Tech stack: Vanilla JS, no framework (wanted it fast and simple). Quiz uses client-side logic, no backend needed. Storage via localStorage for quiz state.
Also wrote detailed articles breaking down why plant proteins tested worse (soil absorption), which certifications actually matter (NSF Certified for Sport, Clean Label Project), and symptoms of lead poisoning from chronic exposure.
The hardest part was distilling 23 products + complex heavy metal data into a simple 60-second quiz without oversimplifying the safety concerns.
Happy to answer questions about the data, methodology, or implementation. Feedback welcome!
