Poor eyesight is one of the most common complaints as people age, and many rely on corrective glasses without ever looking into what else might support long-term eye health. Saffron for eyesight has drawn scientific interest: this culinary spice has been studied for a possible role in supporting vision, particularly in people with age-related macular degeneration.
What Does the Research Say About Saffron and Eye Health?
Early-stage clinical research has looked at whether saffron may support eye health, including in people with age-related macular degeneration, or AMD (a leading cause of vision loss in older adults). In a small clinical study, patients with early AMD who took about 20 mg of saffron daily for three months showed improvements on an objective test of retinal function known as flicker sensitivity, along with some reports of clearer vision (Falsini B, et al. “Influence of Saffron Supplementation on Retinal Flicker Sensitivity in Early Age-Related Macular Degeneration.” Investigative Ophthalmology & Visual Science, 2010; 51(12):6118-6124; PMID: 20688744; follow-up findings in Piccardi M, et al. “A Longitudinal Follow-Up Study of Saffron Supplementation in Early Age-Related Macular Degeneration: Sustained Benefits to Central Retinal Function.” Evidence-Based Complementary and Alternative Medicine, 2012;2012:429124; PMID: 22852021). These are encouraging but preliminary results from small trials, not proof that saffron treats or cures AMD or any eye disease. Saffron supplements are not a substitute for regular eye exams or medical treatment, and anyone with vision changes or a diagnosed eye condition should be evaluated and treated by an eye doctor before adding any supplement.
How Saffron May Support Retinal Function
Dr. Silvia Bisti, a researcher who has studied saffron’s effects on the retina, has suggested the spice may influence genes involved in regulating the cell membrane’s fatty acids, a mechanism researchers believe could play a supportive role in visual function. Saffron is often used as a spice in a variety of foods, but based on these early findings, scientists are exploring whether saffron extracts might one day serve as a complement to standard treatment for AMD patients — always under a doctor’s guidance, not in place of it.
Saffron contains carotenoid antioxidants, known as crocin and crocetin. Antioxidant activity in crocin is thought to be potent and may help limit the formation of lipid peroxidase (damage to tissues that can contribute to several diseases). Some research also suggests saffron may help partially restore the activity of superoxide dismutase (SOD), one of the antioxidant enzymes in the body that reduces oxidative stress. Researchers are studying whether this spice may help support the activity of this enzyme in patients with AMD.
Should You Try Saffron for Eyesight?
If you feel your vision needs support, saffron may be worth discussing with your doctor as a possible complement to your eye care routine — but it should never replace proper diagnosis and treatment, and you should not exceed recommended amounts without medical advice.
