What Are the Side Effects of PreserVision AREDS?
Skin can become yellow due to the beta-carotene in PreserVision AREDS, while severe hemorrhaging is rare, according to WebMD. Venous blood clotting, blurred vision, dizziness, nausea and breast tenderness are also rare. PreserVision is a supplement containing antioxidant vitamins and minerals, according to Bausch + Lomb. PreserVision AREDS2 retains the original PreserVision formula but substitutes zeaxanthin and lutein for beta-carotene.
PreserVision AREDS contains vitamins A, C, E, zinc and copper, a combination that slows age-related macular degeneration development, explains Bausch + Lomb. The acronym refers to a 10-year study of age-related eye disease conducted by the National Eye Institute. Its results showed that patients with AMD in moderate to advanced stages who took two supplement pills each morning and two each evening with meals experienced slowed progression of the disease, which causes vision loss.
Based on the subsequent five-year study AREDS2, Bausch + Lomb replaced vitamin A, the source of beta-carotene that caused skin discoloration, with the nutrients zeaxanthin and lutein, notes the company. The dosage of PreserVision AREDS2 is one supplement soft gel each morning and one each evening with meals.
Zeaxanthin and lutein function as antioxidants in the eyes and decrease the risk of age-related macular degeneration and cataracts, according to the American Optometric Association. People normally gain these nutrients from foods such as cooked kale, collards, spinach, broccoli and eggs.
