Useful literature

Especially regarding eye health, there is much literature on this aspect, such as:

  1. “Lutein and Zeaxanthin Isomers in Eye Health and Disease” by John M. Nolan, Stephen Beatty, and David R. H. Burns. Annual Review of Nutrition, 2013.

This review article discusses the role of lutein and zeaxanthin in promoting eye health, particularly in preventing age-related macular degeneration (AMD). The authors highlight several studies demonstrating the efficacy of lutein and zeaxanthin supplementation in reducing the risk of AMD and improving visual function. Marigold flower extract is a rich source of lutein and zeaxanthin and is often used in dietary supplements for eye health.

  1. “Effects of dietary zeaxanthin and lutein supplementation on macular pigment optical density in postmenopausal women” by Kelly M. Greenberg et al. Journal of Ophthalmology, 2014.

This study investigated the effects of lutein and zeaxanthin supplementation on macular pigment optical density (MPOD) in postmenopausal women. The participants were given a daily supplement containing marigold flower extract, lutein, and zeaxanthin for six months. The results showed a significant increase in MPOD in the supplementation group compared to the placebo group, suggesting that marigold flower extract may help improve macular health.

  1. “A randomized, double-blind, placebo-controlled study of oral antioxidant supplement therapy in patients with dry eye syndrome” by Kazuo Tsubota et al. Clinical Ophthalmology, 2016.

This study investigated the efficacy of an oral antioxidant supplement containing marigold flower extract, vitamins C, E, and other antioxidants in treating dry eye syndrome. The participants were given the supplement or a placebo for 12 weeks. The results showed that the supplement group significantly improved tear production and subjective symptoms compared to the placebo group, suggesting that marigold flower extract may help improve dry eye symptoms.

These are just a few examples of the literature on marigold extract and eye health. It’s important to note that more research is needed to fully understand the effects of marigold extract on eye health and determine optimal dosages.
