Is Glutathione an effective anti-ageing supplement?

Glutathione is a powerful antioxidant that plays a crucial role in the body. It helps protect cells from damage, supports the immune system, and aids in detoxification processes. Glutathione levels can decrease due to various factors such as aging, stress, and exposure to toxins.

Supplementation with glutathione or its precursors (like N-acetylcysteine) has been proposed for various health benefits, including:

Boosting antioxidant levels

Glutathione is a potent antioxidant that can help neutralize free radicals in the body.
Supporting liver health: Glutathione plays a role in detoxification processes in the liver.
Improving skin health: Some believe that glutathione can lighten skin by reducing melanin production, though this use is controversial.

Supporting immune function

Glutathione may help strengthen the immune system.
Reducing symptoms of Parkinson’s disease: Some preliminary research suggests that glutathione might help reduce symptoms of Parkinson’s disease when given intravenously.

However, there are several considerations and potential downsides to glutathione supplementation:


Oral supplementation of glutathione might not be very effective because it’s broken down in the digestive system before it can be absorbed. Liposomal forms or other delivery methods might be more effective.
Potential side effects: Some people might experience side effects like bloating, cramps, and allergic reactions.
Cost: Glutathione supplements can be expensive.

Lack of long-term studies:

While some short-term studies suggest benefits, long-term effects and optimal dosages are not well-understood.

If you’re considering glutathione supplementation

Consult with a healthcare professional: Before starting any supplement, it’s essential to discuss it with a doctor or another healthcare provider to ensure it’s appropriate for your individual circumstances.

Consider your goals: If you’re looking to address a specific health concern, research whether glutathione supplementation has been shown to be effective for that issue.

Quality matters: If you decide to take a supplement, choose a reputable brand and consider third-party testing for purity and potency.

In summary, while glutathione supplementation might offer some health benefits, it’s essential to approach it with caution and be informed about potential risks and benefits. Always consult with a healthcare professional before starting any new supplement.
