About Nature’s Sunshine Defense Maintenance
Your body faces daily exposure to environmental stressors, processed foods, and other factors that can challenge your natural defenses. Defense Maintenance provides comprehensive nutritional support by combining essential antioxidant vitamins and minerals with a powerful blend of traditional herbs and nutrient-rich vegetables. This carefully formulated supplement is designed to support your body’s natural defense mechanisms through multiple pathways.
The foundation of Defense Maintenance lies in its potent antioxidant vitamin complex. Each two-capsule serving delivers 784 mcg RAE of vitamin A (as beta-carotene), 240 mg of vitamin C, and 88 mg of vitamin E. These three vitamins work synergistically to help protect cells from oxidative stress and support normal immune function. Vitamin A supports the health of mucous membranes, your body’s first line of defense, while vitamin C contributes to immune cell function and collagen formation. Vitamin E helps protect cell membranes from free radical damage.
Essential Minerals for Immune Support
Defense Maintenance also provides important trace minerals that play crucial roles in immune function. The formula includes 10 mg of zinc and 50 mcg of selenium, both essential for maintaining normal immune system activity. Zinc is involved in immune cell development and function, while selenium acts as a cofactor for important antioxidant enzymes in the body. These minerals work together with the vitamins to provide comprehensive nutritional support.
Powerful Herbal and Vegetable Complex
What sets Defense Maintenance apart is its 398mg proprietary blend of carefully selected herbs and vegetables. This complex includes traditional herbs like astragalus root, which has been valued in traditional Chinese medicine for supporting the body’s natural defense systems. Reishi mushroom, often called the “mushroom of longevity,” contains beta-glucans and other compounds that may support immune function.
The formula also features concentrated cruciferous vegetables, including broccoli flowers and cabbage leaf. These vegetables contain glucosinolates, sulfur-containing compounds that support the liver’s natural detoxification processes. Cruciferous vegetables have been extensively studied for their role in supporting overall health and providing antioxidant benefits.
Nutrient-dense grasses like barley grass and wheat grass contribute additional vitamins, minerals, and chlorophyll to the formula. These green superfoods provide concentrated nutrition and may help support energy levels and overall vitality. The inclusion of pau d’arco inner bark, schisandra fruit, and eleuthero root rounds out the herbal complex with adaptogenic and traditionally supportive plants.
