Glutathione supplements are gaining popularity for promises ranging from glowing skin to anti-aging effects. However, medical experts warn that most of these claims lack strong scientific backing.
Glutathione is a naturally occurring substance produced in the liver. It is made from three amino acids: glycine, cysteine, and glutamic acid.
It plays a vital role in tissue repair, protein production, and supporting the immune system.
Glutathione is widely marketed for improving skin clarity, slowing aging, and supporting heart and liver health.
However, experts say there is no clear scientific evidence confirming its effectiveness for these uses.
Despite its popularity in supplements and skincare products, research supporting these benefits remains limited.
Where has it shown potential?
According to researchers, glutathione may have a specific medical use.
Experts note that glutathione can help reduce nerve damage caused by the cancer drug cisplatin when administered intravenously (IV).
This treatment is only effective in certain patients and must be carried out under strict medical supervision.
Safety, side effects, and risks
Glutathione supplements are considered possibly safe at a dose of 500 mg per day for up to two months. However, data on long-term safety is limited.
Possible Side Effects
-
Inhalation may be safe, but research is incomplete
-
Topical use may cause itching or allergic reactions
-
IV injections may lead to a sudden drop in blood pressure
Who should avoid it?
Certain groups are advised to exercise caution or avoid glutathione altogether.
At-Risk Individuals
-
Pregnant or breastfeeding women due to insufficient safety data
-
Asthma patients, as inhalation may worsen symptoms
-
Individuals considering glutathione shots without medical supervision
Dosage remains unclear
Experts highlight that there is no reliable scientific guidance on the correct dosage of glutathione.
They also stress that natural supplements are not always safe and should not be used without consulting a doctor.
