Supports liver health

Nonalcoholic fatty liver disease (NAFLD) is a common chronic disease caused by excessive fat accumulation in the liver. Over three months, glutathione supplementation resulted in improved liver enzymes, lower triglycerides, and lower HbA1c, a blood sugar level marker. The researchers concluded that glutathione promotes liver metabolism and improves NAFLD. Further research is recommended.

Improves insulin sensitivity

Insulin is a hormone that transports glucose from the bloodstream to body cells. Obesity and other metabolic conditions increase the risk of insulin resistance, which can progress to type 2 diabetes. In one small study, researchers discovered that patients with type 2 diabetes had lower levels of glutathione than healthy controls. Another study suggested that glutathione deficiency may play a significant role in the pathophysiology of type 2 diabetes.

Reduces oxidative stress

Glutathione is an antioxidant that neutralizes free radicals and reduces oxidative stress, which can harm cells and lead to disease. In a clinical trial, daily glutathione supplementation increased glutathione levels in red and white blood cells by an average of 30 to 35% and reduced oxidative stress.

Reduces the impact of aging on skin

In one study, researchers discovered that glutathione supplementation was more effective than placebo in improving wrinkles, reducing pigmentation, and increasing skin elasticity. Additional research is recommended.
