Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Anthocyanidins are a class of flavonoids found in various fruits and vegetables, especially those with red, blue, or purple pigments (e.g., berries, grapes). Scientific interest in anthocyanidins (and their glycosylated counterparts, anthocyanins) has grown due to their antioxidant, anti-inflammatory, and vasoprotective properties. Several preclinical and clinical studies have examined their cardiovascular benefits. Anthocyanidins have been shown to improve endothelial function, reduce oxidative stress, and inhibit platelet aggregation—all relevant to cardiovascular health and potentially beneficial in conditions such as heart failure or "heart weakness."

A number of epidemiological studies have associated higher intake of anthocyanin-rich foods with reduced risk of cardiovascular disease. Some randomized controlled trials (RCTs) have demonstrated improvements in blood pressure, vascular function, and cholesterol profiles with anthocyanin supplementation. However, while these effects are promising, direct evidence for the use of isolated anthocyanidins to treat heart failure specifically is limited, and most clinical studies focus on surrogate markers (e.g., blood pressure, endothelial function) rather than hard clinical endpoints in heart failure patients.

Overall, the use of anthocyanidins for "heart weakness" is supported by a moderate level of scientific evidence, mostly extrapolated from broader cardiovascular research. Further large-scale, high-quality clinical trials are needed to confirm their efficacy specifically for heart failure or cardiac insufficiency.
