Evidence grades. Every ingredient above is graded A–D based on the strength of the human clinical trial record. A-grade ingredients have multiple well-designed RCTs converging on the same effect. D-grade ingredients are mostly pre-clinical with no published human efficacy data — they're listed for completeness, not endorsed. See the methodology page for details.
