Fatigue, weakness, increased susceptibility to infections, and oxidative stress-related issues may indicate a deficiency in glutathione, a vital antioxidant in the body. While glutathione itself doesn’t cause symptoms, imbalances are associated with various medical conditions. Deficiency is linked to liver disease, neurodegenerative disorders, and immune system dysfunction. Addressing glutathione deficiencies through supplementation or lifestyle changes is crucial for overall health and cellular well-being. Persistent symptoms should prompt consultation with healthcare professionals for proper evaluation and guidance.
