Decoding Your Product's Health Score
Every product in Elemental receives a health score based on rigorous analysis of lab-tested contaminant data. But what do these scores really mean? Let's break it down so you can make confident, informed decisions.
The Three-Tier Color System
Elemental uses a simple, intuitive color-coding system:
- Green (Safe): All contaminants are well below safety limits set by the FDA, EPA, and international health organizations. These products are safe for regular use.
- Amber (Caution): One or more contaminants approach or slightly exceed recommended limits. While not immediately dangerous, you may want to limit use or choose alternatives.
- Red (Avoid): Contaminant levels significantly exceed safety thresholds. We recommend avoiding these products, especially for children, pregnant individuals, or those with sensitivities.
How We Calculate Scores
Our scoring algorithm considers:
- Contaminant Types: Some toxins (like lead, arsenic, PFAS) are weighted more heavily due to their health impacts
- Concentration Levels: How much of each contaminant is present compared to safety limits
- Number of Contaminants: Products with multiple concerning substances score lower
- Recent Testing: We prioritize the most recent lab data and flag products when new tests reveal concerns
Understanding Contaminant Data
When you view detailed contaminant information, you'll see:
- Contaminant Name: The specific substance detected (e.g., "Lead," "PFAS," "BPA")
- Level Detected: The concentration found in testing (measured in ppb, ppm, or µg/L depending on the substance)
- Safety Limit: The maximum recommended level from regulatory bodies like the FDA or EPA
- Percentage Over/Under: How the detected level compares to the safety limit
Common Contaminants to Watch
Here are some of the most frequently detected contaminants and what they mean:
- PFAS (Forever Chemicals): Used in non-stick coatings and water-resistant products. Linked to immune system issues and cancer.
- Lead: Found in old pipes and some cosmetics. Particularly dangerous for children's development.
- BPA/BPS: Plastics additives that can disrupt hormones. Common in food containers and water bottles.
- Arsenic: Can contaminate water supplies and rice-based products. Long-term exposure increases cancer risk.
What If My Favorite Product Scores Poorly?
Don't panic! A low score doesn't mean you'll get sick from occasional use. Consider these factors:
- Frequency of Use: Products you use daily matter more than occasional items
- Exposure Route: Ingested products (food, water) have more impact than topical ones
- Individual Sensitivity: Children, pregnant individuals, and those with health conditions should be more cautious
