As the world scrambles to find a cure for COVID-19, health experts have suggested boosting the body’s immune system may help minimize the effects and hasten the recovery from the disease. Nutraceuticals are the pharmaceutically blended products that possess both nutritional as well as the medicinal value. Such a product is designed to improve the immune system and help us fight dangerous viruses like COVID-19. There are different types of immune cells which work in a synchronized manner to identify, locate, capture and to destroy the pathogens. Enormous oxidative stress which the pathogens generate needs to be combated with a powerful antioxidant payload which is usually concentrated in immune cells. For example, Vitamin C is present at 100 times higher concentration inside immune cells than that in blood and while these cells fight infection, concentrations go still higher. The ally of Vitamin C in such situation is Glutathione, the master antioxidant. Vitamin C and Glutathione work in sync and re-generate each other. Glutathione is produced by the body itself however; age, pollution, infections cause blood glutathione levels to deteriorate. Supplementing Vitamin C with Glutathione or with Glutathione precursors like N-Acetyl Cysteine (NAC) helps boost immunity and offers better ability to fight against infections.
