Every claim, graded.

How tiers get assigned

Tier reflects how confident Realised is in a claim, not just the type of study behind it. A meta-analysis with conflicting findings can sit at Moderate. A small RCT with a clean mechanism and replicated direction can sit at Strong. Each entry shows its tier reasoning: what evidence moved it up, what caveats hold it back, and where industry or publication bias may distort the picture.

Many entries have mixed tiers across dimensions. Vitamin D might be Strong for the underlying physiology, Moderate for clinical depression effect, and Emerging for respiratory infection prevention. We surface that split rather than flatten it.
