Diatomaceous earth (food grade)

Tier 3 — weak evidence · Detox claims · Silica

Marketed for "detox" and silica content, but no trial evidence supports any health benefit. Made from fossilized algae and used mainly as a pest control product. The food-grade form is generally considered safe to consume, but no therapeutic claims are supported by science. Your money is better spent on supplements with actual clinical evidence.

Dose: No evidence-based dose; no clinical benefit demonstrated
