There are many other nutrients that are available in all-natural products. Some of the most important nutrients include the vitamins A, C, and E, selenium, and ginkgo biloba. These all-natural ingredients offer benefits to the entire body and improve overall health. For instance, studies have shown that nutrients like selenium and ginkgo biloba can reduce the risk of age-related eye diseases, such as macular degeneration and cataracts. This research is encouraging, because it means there is a possibility that all-natural therapies can improve eye health and vision loss.
