Glutathione food additive raw materials approved by relevant national departments must comply with GB standards, and product packaging must clearly indicate the health food approval number and health food product registration number. Its production process requires strict quality control to ensure that indicators such as heavy metals and microorganisms meet safety limits. According to current research, appropriate supplementation in healthy individuals has no significant side effects; however, patients with immunodeficiency or metabolic diseases should use it under the guidance of a doctor. The shelf life is typically 36 months; after opening, it should be sealed to prevent moisture absorption and clumping.
Glutathione food additive raw materials have superior biocompatibility and can be directly absorbed and utilized by the human body. In animal experiments, its antioxidant efficiency is dozens of times that of vitamin C, and it can synergistically enhance the protective effect of vitamin E. In practical applications, foods containing added glutathione show significantly improved vitamin retention during shelf life, while also improving product taste and reducing off-flavors caused by oxidation. Its powder form facilitates precise dosing in industrial production, reducing formulation adjustment costs.
