Support for a healthy cardiovascular system
Some of the key research suggests that quercetin supports the function of the endothelium, the interface of the vascular system where oxygen and carbon dioxide are exchanged. Quercetin has been highlighted as a compound that holds potential in helping to maintain the normal structure and function of endothelial tissue.
Support for respiratory function
Quercetin showed a propensity for helping respiratory function of guinea pigs when challenged with a substance to which the guinea pigs had been sensitized. Additionally, a recent mouse model has shown that quercetin may support healthy airway function by maintaining a healthy balance of immune system cells within the respiratory system.
Allergic response
Quercetin helps down regulate the allergic response by reducing histamine release. Supports mast cell and basophil integrity.
Bromelain - In vitro trials have shown bromelain can alter immune cell secretion of cytokines in a way that would be favourable for maintaining balance in the immune system. Several clinical studies have revealed the effects of bromelain on the musculoskeletal system, joint health, circulation and respiratory health.
