Yes, the expensive spice, and one of the few ingredients with human retina data.
Retina ClearIn plain words
Saffron is the dried stigma of the crocus flower. Crocin and crocetin give it colour and most of its studied activity.
Retina ClearWhat the evidence shows
A small trial published in 2010 gave people with early macular degeneration 20 mg of saffron daily and measured better retinal flicker sensitivity after a few months. Other small studies point the same way, but sample sizes are modest.
In this capsule
Saffron stigma extract is listed with no dose. The studied amount was 20 mg, and there is no way to check whether the capsule reaches it.
Watch-outs: Food amounts are safe. Very large doses can be harmful, and high doses are avoided in pregnancy.
Common question
Is saffron proven for eyes?
Promising in small studies, not proven. It deserves attention but not a guarantee.
