Pure Encapsulations M-R-S Mushroom Formula offers support for the immune system, liver, heart and blood. Antioxidants are naturally found in plant-based foods. Cooking often destroys much of their antioxidant content, so its best to eat fruits and vegetables raw in order to gain the maximum benefit. If you dont eat a lot of raw plant-based foods, Pure Encapsulations' M/R/S Mushroom Formula by Pure Encapsulations may help you boost your intake. There are many possible causes of a worn-down immune system. These causes include a poor diet heavy in processed foods, nutritional deficiencies, illnesses, medication use, or exposure to toxins. You may be able to strengthen your immune system by increasing your antioxidant intake. Antioxidants are beneficial molecules that help prevent free radicals (harmful molecules) and toxins from harming your body and weakening immunity. Antioxidants also may improve your cardiovascular health while supporting the liver. If you get sick often or easily, you may have a weak immune system. Your immune system normally fights off invaders to keep you from getting sick. However, when it's not strong enough to do the job, you may become ill. Occasional minor illnesses, such as the common cold, arent usually a big concern, but they can interfere with your daily life and comfort. Recommended use: 1 capsule daily with a meal, or as directed by a healthcare professional.
