The sensitive tissues of the eyes are particularly vulnerable to the ravages of free radicals. That's why antioxidants play such important roles in maintaining eye health. Swanson Standardized Lutein & Bilberry combines two of nature's most effective eye-specific antioxidants to help maintain healthy vision. Each softgel provides 20 mg of standardized bilberry extract and 6 mg of lutein. For greater vision protection, pair bilberry and lutein supplements with Swanson Ultra Zeaxanthin, a carotenoid that offers demonstrated health benefits to the macula and lens of the eye.
