What is it

Delphinidin is an anthocyanidin pigment that gives blue and purple colors to many fruits and flowers, including blueberries, pomegranates, blackcurrants, and grapes. It is typically present as glycosides like delphinidin-3-rutinoside or delphinidin-3-glucoside.

Vascular/metabolic support (anthocyanin family)

Limited Evidence

Anthocyanin-rich diets are associated with cardiometabolic benefits in cohort studies; small trials of standardized anthocyanin extracts show modest endothelial effects.

How it works

Like other anthocyanins, delphinidin and its glycosides have antioxidant and anti-inflammatory properties. Preclinical work suggests effects on endothelial function, glucose handling, and tumor cell signaling. Bioavailability of the intact glycosides is low, and many in vivo effects are attributed to microbial metabolites that enter circulation.

Dosage

No RDA. Anthocyanin trials use 80-320 mg/day total; delphinidin is one of several anthocyanidins consumed.

When and how to take it
