Immunocal is a specially formulated protein derived from whey. It contains glutathione building blocks. How does Immunocal work? The immune system is incredibly complex, but a major cornerstone relies on its ability to obtain a molecule called glutathione. Glutathione exists in every cell of your body and is essential for life and critical for health. This molecule is constantly being used up in dozens of your body's functions and is difficult to replace. Glutathione is your body's master antioxidant, its chief detoxification enzyme and is literally food for the immune system. Immunocal is a natural source of the glutathione precursor cysteine for the maintenance of a strong immune system. Many natural products are available that claim to help your immune system, but very few have undergone the rigorous testing and published human trials that Immunotec has accomplished over the years. Over forty published scientific and medical articles attest to its remarkable credibility. Besides its ability to raise glutathione and all the benefits that come with it, Immunocal proteins have a very high BV (Biological Value).
