Ganoderma lucidum, Tremella fuciformis and Auricularia auricula-judae show particular promise for supporting cardiovascular health, with actions including:
One clinical study reported a polysaccharide extract of G. lucidum to reduce chest pain, palpitations and shortness of breath in patients with coronary heart disease (5.4g/day) while triterpenoid ganoderic acids from Ganoderma tsugae have demonstrated cardioprotective properties through reduction in oxidative stress and T. fuciformis polysaccharides have been shown to help protect the cells lining the blood vessels, damage to which is an important contributory factor in the development of cardiovascular disease1-5.
Cordyceps species also show significant cardioprotective properties and are approved in China for the treatment of arrythmia, at least partially due to their adenosine content. In addition, cordycepin has been shown to prevent ischaemia and reperfusion injury in animal models6-8.
Polysaccharide extracts of G. lucidum, T. fuciformis and A. auricula-judae/Auricularia polytricha (1-3g/day) can provide useful cardiovascular support and be used at higher levels or in combination with G. lucidum ethanolic extract or cordycepin-rich Cordyceps in more severe cases.
