Flavanones, a subclass of flavonoids commonly found in citrus fruits such as oranges and grapefruits, have been investigated for their potential cardiovascular benefits. Several scientific studies, including epidemiological and experimental research, suggest that flavanones may be associated with improved heart health, primarily through their antioxidant, anti-inflammatory, and vasodilatory effects. These compounds, particularly hesperidin and naringenin, have been shown in animal and some human studies to reduce blood pressure, improve endothelial function, and decrease oxidative stress—factors that may contribute to the prevention or amelioration of heart disease and related "weakness" of the heart.

However, while laboratory and animal data are promising, the direct evidence from large-scale human clinical trials remains limited and not wholly conclusive. Most studies focus on general cardiovascular risk factors rather than specifically on "heart weakness" (a nonspecific term that may refer to conditions such as heart failure or reduced cardiac function). Thus, while there is a scientific rationale and some supportive data for flavanones in supporting heart health, the strength of the clinical evidence is moderate and does not yet firmly establish flavanones as a treatment for heart weakness. More rigorous, targeted human studies are needed to confirm their efficacy for this specific condition.
