Glutathione · Antioxidant support
Glutathione: Your body's own antioxidant, as one part of a bigger plan.
Glutathione is the main antioxidant your body makes for itself, built from three amino acids and found in nearly every cell. At Integrated Functional Health it is an optional addition to a plan built on nutrition, sleep and stress regulation, the foundations that shape your own glutathione every day.

Glutathione in brief
Glutathione is the antioxidant your cells make from three amino acids. It neutralizes free radicals, helps recycle other antioxidants such as vitamin C, and plays a central role in how the liver processes substances. Supplemental glutathione is designed to add to the body's own supply, though how much reaches the cells is still being studied.
- What it is: The body's main internal antioxidant, made from three amino acids.
- How it is taken: A small injection under the skin, twice a week.
- Often explored for: Antioxidant support, energy and overall wellbeing.
- How long: A course of about eight weeks.
- Status: Compounded by licensed pharmacies; not an FDA approved product.
What it is
What is Glutathione?
Glutathione is a small molecule made from three amino acids: glutamate, cysteine and glycine. Your cells build it themselves, every day, and it is present in almost every tissue, with especially high amounts in the liver. Scientists often describe it as the body's master antioxidant because so many other protective systems depend on it.
Your own production depends on what you eat (particularly protein foods that supply cysteine), how well you sleep, and how much strain your body is under. Glutathione is also sold as an oral supplement and given in clinics by IV. The version offered through IFH is a small injection under the skin, prepared by an independent licensed pharmacy and prescribed by an independent licensed provider who decides whether it suits you.
How it works
How Glutathione works
Every cell makes energy, and making energy produces unstable molecules called free radicals as a byproduct. In small amounts they are normal and even useful. When they build up faster than the body can neutralize them, the result is called oxidative stress, which can wear on cells over time.
Glutathione is one of the body's main ways of keeping that balance. It neutralizes free radicals directly, and it helps recycle other antioxidants, such as vitamin C, so they can keep working. In the liver it also attaches to many substances the body needs to clear, making them easier to remove through normal processing.
Your body manages its glutathione supply carefully, making more when it needs it. How much an injection under the skin adds to the levels inside your cells has not been well studied.
What it may support
What people explore Glutathione for
Antioxidant balance
May support the body's own defenses against everyday oxidative stress.
Normal liver processing
Glutathione is central to how the liver handles and clears many substances.
Energy and wellbeing
Some people explore it as part of a plan for steadier energy.
A broader plan
Works best alongside protein, vegetables, sleep and stress regulation.
How it is used
What taking Glutathione looks like
Your independent licensed provider sets your dose and adjusts it over time. Here is what the routine involves.
- Form: A small injection under the skin of the abdomen, thigh or upper arm. Rotate the spot each time.
- How often: Twice a week, spaced a few days apart.
- How long: A course of about eight weeks, after which your provider reviews how you are doing.
- Dose: Your provider sets the dose that suits you.
- Storage: Follow the storage instructions from your pharmacy.
What the research says
The evidence, plainly
Glutathione itself is one of the best studied molecules in human biology. Supplemental glutathione is a different question, and the human evidence for it is modest and mixed.
For years, researchers believed glutathione taken by mouth was mostly broken down in the gut. A four week trial of daily oral glutathione (Allen and Bradley, 2011) found no meaningful change in markers of oxidative stress. A larger six month trial (Richie and colleagues, European Journal of Nutrition, 2015) found that daily oral glutathione did raise levels in the blood and in cells. The two results point in different directions, and neither looked at how people felt.
Injections under the skin have been studied far less than oral or IV forms, and there are no large trials of this route. The honest summary: it is a reasonable thing to explore within a plan, and not something the research has settled.
Safety
Who it suits, and what to watch for
It may not be right for
- A known allergy to glutathione or any ingredient in the preparation
- Asthma, especially with inhaled forms, which can tighten the airways
- Sensitivity to sulfites
- An organ transplant with immunosuppressive medicines
- Current chemotherapy or radiation, or a history of cancer
- Severe kidney or liver impairment
- Anyone who is pregnant or breastfeeding
- Current use of cocaine or methamphetamine
Your provider reviews your full health history and current medications before prescribing.
Possible side effects
- Redness, soreness or swelling where you inject
- A small bump or bruise at the injection site
- Mild stomach upset or bloating, which is uncommon
- Rash or itching, which is uncommon
- Allergic reactions, which are rare
If a side effect is severe or does not settle, contact your provider. For wheezing, trouble breathing, swelling of the face or throat, or other signs of a serious allergic reaction, call 911.
How it fits your plan
More than a prescription
Your own glutathione depends on daily life: the protein you eat, the vegetables on your plate, the hours you sleep, alcohol, and how long your stress response stays switched on. That is why glutathione is never the plan by itself at IFH. Our functional health coaching works on those foundations directly, and they are what support your own production every day.
Regulate, Integrate, Optimize is the thread. When your nervous system moves out of constant alarm, sleep and recovery improve and the body has room to do its own upkeep. Functional genomics can show tendencies in the genes that shape your antioxidant pathways, so coaching can be more specific to you. Lab work at a local Labcorp or Quest location and professional grade supplements are there if you want them, to round out the plan.
Good to know
The details that matter
- Glutathione for injection is prepared by licensed compounding pharmacies. It is not an FDA approved product and has not been reviewed by the FDA for safety, effectiveness or quality.
- It is prescribed only after an independent licensed medical provider reviews your health history and decides it is appropriate. Your provider also sets your dose.
- Your medication is prepared by an independent licensed pharmacy and shipped to your door, in most states.
- Tell your provider about every medication and supplement you take, especially transplant medicines or anything for cancer care.

Questions
Questions about Glutathione
If my body already makes glutathione, why add more?
For many people, the most effective step is helping the body make its own: enough protein, plenty of vegetables, good sleep, less alcohol and a calmer stress response. Some people choose to add glutathione alongside those habits. Your provider can talk through whether it makes sense for you.
Is an injection better than a capsule?
An injection bypasses digestion, which is the main reason people choose it. Oral glutathione has more research behind it than injections under the skin, and that research is mixed. Neither route has been shown in large trials to make people feel better, so it is worth keeping expectations realistic.
What might I notice?
Some people report feeling more energetic; others notice nothing obvious. Antioxidant support works quietly, in the background, so it is not something most people feel from one day to the next. A full course paired with steady habits, such as good sleep and protein at each meal, gives a fairer picture than any single week.
How is it different from NAD+?
Both are molecules your cells make and use every day. Glutathione is mainly about antioxidant protection. NAD+ is mainly about how cells turn food into energy. They are sometimes used side by side. Your provider will talk with you about which, if either, fits your health and your goals.
How do I get started?
Book a 30 minute consultation with Matt DeWild, RN, at the clinic or by telehealth. You will talk about your goals and your history, and Matt will explain how the medical assessment with an independent licensed provider works. There is no cost for the consultation and no obligation.
