What It Actually Is
Saffron is a spice derived from the stigmas of the Crocus sativus flower, traditionally used in cooking and, in supplement form, studied for mood and antioxidant support.
What Research Generally Shows
Saffron has a growing research base, primarily around mood support, with a smaller body of research on antioxidant activity.
The Honest Gap
Research commonly uses doses around 30mg — the smallest of the six blend ingredients' typical studied amounts, and the one most plausibly within reach of the 570mg total. Even so, the exact amount here isn't disclosed.
