GCMAF 300mg Triple strength in vegetarian capsules. GcMAF is naturally occurring within a healthy immune system. It is responsible for activating Macrophages which eradicate bacteria, viruses and other unwanted cells within the body. When we become sick, the body's capacity to produce it's own GcMAF becomes inhibited. The accelerated release of nagalase enzymes prohibit glycoprotein cells from activating macrophages, thus rendering our immune system defenseless. This is where GcMAF can help. 300mg/capsule. Triple strength; 1 capsule per day.
