A spice extract (Crocus sativus), with no dose disclosed.
Saffron Stigmas Extract, from Crocus sativus, is more commonly studied for mood and eye health than cardiovascular outcomes specifically, though it carries general antioxidant properties.
Typical studied intakes for saffron extract run around 30mg daily on their own — the smallest of the six blend ingredients by typical research dose.
As part of the undisclosed 570mg blend, we can't confirm the actual amount used in Vasoryn.
