What Is Glutathione?
Glutathione is a powerful antioxidant that your body makes on its own. It's built from three building blocks (amino acids) called cysteine, glycine, and glutamic acid, and it's found in nearly every cell in your body. As we get older — or if we've been dealing with illness or stress — our natural glutathione levels tend to drop. That's why some patients benefit from taking it as a supplement.
How Does It Work?
Glutathione protects your cells by neutralizing harmful molecules called free radicals. Think of free radicals as microscopic troublemakers that damage your cells, speed up aging, and can contribute to illness. Glutathione also helps your body flush out toxins and heavy metals. On top of that, it supports your DNA, helps repair tissues, boosts energy production, and keeps your immune system running well.
What Will It Do for Me?
Glutathione works at the cellular level, which means its effects aren't always immediately obvious — but many patients notice improvements in energy, mental clarity, and how they feel overall. Some also see improvements in skin tone and brightness, since glutathione has been shown to reduce cellular damage in the skin. Results vary from person to person and usually build up over several weeks of regular use.
Who Is It Best For?
Glutathione is a great fit for patients taking GLP-1 medications like semaglutide or tirzepatide. These medications put extra demands on your metabolism, and glutathione can help by reducing oxidative stress, supporting your liver, and potentially easing some of the stomach-related side effects that can come with GLP-1 use. It's also a solid option for patients who have finished their GLP-1 program and want to maintain the progress they've made.
How Do I Take It?
The standard dose is 200 mg injected just under the skin (subcutaneously), three times a week — for example, Monday, Wednesday, and Friday. Each dose is drawn from a 200 mg/mL, 30 mL vial. There are no food restrictions or specific timing rules, though many patients prefer to take it in the morning or early afternoon. Be sure to rotate your injection site each time to avoid irritation in one spot.
Are There Side Effects?
Glutathione is generally very well tolerated. The most common side effects are mild and happen at the injection site — things like minor redness, swelling, or tenderness. A small number of patients experience occasional nausea or headaches, especially in the first few weeks. Allergic reactions are rare, but if you notice any signs of one, contact your provider right away.
Is It Right for Everyone?
Glutathione is not recommended if you have a known allergy to any of its ingredients. It's also not recommended for people with asthma, as it may trigger airway tightness (bronchospasm) in those who are sensitive.
