How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

Purified anthocyanins improved FMD in healthy humans in the 2019 experimental program.
Experimental context and source evidence
- evidence_access
- Primary indexed abstract reviewed; full methods, figures, exact doses or endpoint-specific species assignments may remain unextracted.
- experimental_contrast
- {"intervention": "Purified anthocyanin preparation", "comparator": "Control preparation", "endpoint": "Purified anthocyanins improved FMD in healthy humans in the 2019 experimental program.", "effect_direction": "increase", "combination": "single", "conditions": []} Explicit extracted experimental comparison; source-derived draft.
- experimental_model
- Human purified-anthocyanin comparison, distinct from blueberry, metabolite association and mouse-injection experiments.
- interpretation_status
- Source-derived extraction of a fact-checked reference; access is explicit, not independent raw-data verification.
- limitations
- Exact dose-series values not extracted from accessible abstract. Mouse metabolite dosing is not human mediation proof.

**Metabolite-mediated vascular activity has been tested.** A 2019 program compared purified anthocyanins, blueberries and control preparations in people, related circulating metabolites to FMD, and tested selected metabolite administration in mice. Purified anthocyanins improved FMD, while fiber/mineral/vitamin control drinks did not show the same effect. Human associations, mouse interventions and blood-cell gene-expression changes are different evidence layers. They support further metabolite research; they do not prove every correlated molecule is necessary or sufficient in humans. [Rodriguez-Mateos et al., 2019](https://pubmed.ncbi.nlm.nih.gov/30772905/).
