L-Glutathione, reduced, free acid, is a potent antioxidant used to protect cells from oxidative stress and maintain cellular health. It is available in a 100-gram bottle and is commonly used in biochemical research for its role in reducing free radicals and reactive oxygen species (ROS). As a critical component of the body’s defense mechanisms, glutathione helps detoxify cells, boost immune function, and maintain the integrity of cellular structures. In addition, it is widely used in various research areas, including cancer research, metabolic studies, and neurobiology. Glutathione is essential for reducing disulfide bonds, facilitating protein folding, and maintaining cellular balance under stress conditions.
