Methodology

Explains heavy-metal concerns in protein powders and how to interpret published tests — never invents ppm results.

Evidence rules

• No invented laboratory results, certifications, or customer reviews
• No medical advice; ingredient education is not a diagnosis
• No claim that Cantein is low-FODMAP, heavy-metal-free, or condition-specific without linked evidence
• Do not duplicate articles across EMD domains
• Cantein.com remains the primary e-commerce brand

Open research requirements

Compact-keyword landing pages (≈400–500 words, exact intent in title/H1/URL) will be added from the content backlog after SERP checks — not mass-generated thin posts.
