NOW® Immune Renew™ is a potent immune system supporting formulation containing Standardized Astragalus Extract and a High Beta-Glucan Proprietary Mushroom Blend. Astragalus has been shown in non-clinical studies to support a number of aspects of healthy immune function, including the enhancement of T-Cell and Natural Killer Cell activity. Natural killer cells are so named because they destroy unhealthy cells in the body virtually on contact. NOW's Proprietary Blend of eight organic mushrooms provides additional immune support due to its high 1,3 Beta Glucan content. 1,3 Beta Glucans are especially valuable to immune system response, though they're increasingly lacking in today's typical diet. Scientific studies have demonstrated that the 1,3 form of Beta Glucan found in mushrooms possesses remarkable abilities to support both innate and adaptive immunity. A strong, responsive immune system in the foundation of good health. Use NOW® Immune Renew™ to help support healthy immune function throughout the year.*
LIKELY USERS: Everyone seeking a healthy immune system; People on low carb diets or non-whole grain diets that are lacking dietary beta-glucans
KEY INGREDIENTS: Astragalus Root Extract Powder 70% polysaccharides (200 mg). Proprietary blend of 8 organically grown “medicinal mushrooms” (200 mg)
MAIN PRODUCT FEATURES: Vegetarian formula. Polysaccharides in these US-grown mushrooms grown on organic brown rice include 1,3 Beta-glucans and terpenoids. Beta-glucans may stimulate the immune system in different ways. Triterpenoids may act as mild anticoagulants. Each mushroom may have a different effect; for example, one may stimulate T-cells and another Natural Killer cells, aiding in immune defense. Mushrooms have reported beneficial effects on liver health and promoting normal cell growth.
ADDITIONAL PRODUCT INFORMATION: Some extracts from these kinds of mushrooms have been used medicinally in Japan and China. The mushrooms include Turkey Tail, Sun Mushrooms, Maitake, Cordyceps, Phellinus, Lion’s Mane, Reishi and Shiitake. The astragalus extract also contains naturally occurring astragalosides. Mushrooms may help maintain normal cholesterol and triglyceride levels
SERVING SIZE & HOW TO TAKE IT: For everyday use take one or two caps per day, either with meals or on an empty stomach.
COMPLEMENTARY PRODUCTS: Vitamin C to break down beta-glucan structures for better absorption, Inositol Hexaphosphate (IP-6), I3C, Pometrol, mixed carotenoids and antioxidants
CAUTIONS: Pregnant and lactating women and people using prescription drugs should consult their physician before taking any dietary supplement. Do not take with AIDS drugs or if you have an autoimmune disease. Use with caution if using anticoagulants or blood pressure medication, as these mushrooms may have mildly synergistic effects to those drugs. Do not use if you have mold or mushroom allergies (or any sensitivities to mushrooms, cheese, etc.), which can potentially result in hives, rashes, breathing difficulties (including dry mouth or throat), stomach distress, diarrhea, or any other unusual side effect.
