Glutathione
Ingredient · In our Glutathione Injection
Glutathione (L-glutathione)
Glutathione is an antioxidant your cells make on their own, from three amino acids. It's popular for "glow" and detox. The evidence that injecting it helps healthy people is limited, and we'd rather say so up front.1,3
Photo is an illustration, not the medicine. The glutathione in this medicine is made in a lab.
Glutathione is not FDA-approved for skin, energy or general wellness. Studies of injected glutathione are small and inconsistent, and a 2026 review flagged open safety questions.3 Our glutathione is compounded by a licensed pharmacy, and compounded drugs are not FDA-approved.4
The studies below used FDA-approved products or other forms. Our compounded version hasn't been studied in trials, and results may differ.
What it is
Glutathione helps your cells neutralize oxidative stress and recycle other antioxidants like vitamin C. Your body makes it from three amino acids: cysteine, glutamate and glycine.1
Why it's in this product
Some people seek glutathione hoping for brighter, more even skin or more energy. In lab studies it can shift pigment production in skin cells, which is where the "glow" idea comes from.2,3 Whether that translates into visible results from an injection is still an open question.
What the studies in people show
- Randomized trial, oralSupplements raised the body's glutathioneIn a 6-month placebo-controlled trial in 54 adults, oral glutathione (250 or 1,000 mg a day) raised glutathione levels in blood, and levels fell back to baseline a month after stopping.1 This shows it can be absorbed, not that it improves how you feel or look.
- Systematic reviewSome skin lightening, mostly from pills and creamsA 2025 systematic review found that several small randomized trials of oral glutathione, and 0.5% glutathione cream, modestly reduced skin melanin compared with placebo.2
- Review, injectionInjected glutathione: modest, inconsistent resultsA 2026 review of intravenous glutathione found limited evidence of modest, variable skin changes, mostly from small studies that often added vitamin C, making it hard to know what glutathione did on its own.3
What we don't know yet
Whether injected glutathione improves skin, energy or health in healthy people, what dose or schedule makes sense, and how safe repeated injections are over time.3
Safety, in plain English
Possible risks raised in the medical literature include allergic reactions and, with intravenous use, concerns about the liver, kidneys and hormones that haven't been well studied.3 Your clinician will go over these with you.
