Glutathione
Supplied by U.S. pharmacies.
Description
Glutathione Identity and Composition Facts
- Glutathione is a molecule synthesized within human cells from glutamate, cysteine, and glycine.[4]
- Miller's Pharmacy catalogs this formulation as an injectable preparation.
- The catalog listing does not establish an administration route such as intravenous, intramuscular, or subcutaneous injection.
Glutathione is a naturally synthesized tripeptide composed of glycine, glutamate, and cysteine that functions physiologically as an antioxidant.[4] Miller's Pharmacy catalogs this formulation as an injectable compounded medication. The cited Hauser trial does not establish wellness, recovery or detoxification benefits for this product.[1]
Biochemical Identity and Injectable Product Form
Its molecular structure consists of three bonded amino acids: glycine, glutamate, and cysteine. The Miller's Pharmacy catalog lists this item as an injectable preparation of compounded glutathione. The catalog entry identifies the item as an injection without establishing a subcutaneous, intramuscular, or intravenous delivery method.
Primary Clinical Research and Evidentiary Boundaries
In a randomized, double-blind, placebo-controlled pilot study, Hauser et al. evaluated intravenous (IV) glutathione in individuals diagnosed with Parkinson's disease.[1] Changes in clinical symptom scores in the active treatment group did not demonstrate statistical significance when compared with the placebo group.[1]
The findings from the Hauser et al. clinical trial cannot establish efficacy for elective wellness applications.[1] Investigational results in a Parkinson's disease cohort do not predict outcomes for healthy individuals seeking enhanced energy or muscle recovery.[1]
Regulatory Sourcing Standards and Quality Considerations
The Food and Drug Administration (FDA) issued an alert regarding the quality of active pharmaceutical ingredients used in compounded glutathione injectables.[2] FDA reported adverse events after intravenous glutathione compounded using supplement-grade ingredient from a particular supplier.[2] FDA says supplement-grade ingredients are inappropriate for injectable drugs and may contain impurities or endotoxins.[2]
The FDA notice does not verify the source or quality of this cataloged Miller’s product.[2] FDA recommends checking ingredient source with the compounder.[2]
Frequently asked questions
What is glutathione?
Glutathione is a molecule your body makes naturally.[4] It consists of three amino acids: glycine, glutamate, and cysteine. Normal cellular function does not prove that administering supplemental glutathione produces clinical benefits.[1]
What specific formulation does the pharmacy catalog describe?
The Miller's Pharmacy catalog lists a compounded glutathione formulation labeled for injection. The listing designates the preparation as an injectable drug but does not specify an intravenous, intramuscular, or subcutaneous administration protocol.
Are oral and injectable glutathione forms interchangeable?
The cited intravenous trial does not establish that oral or other injected forms are interchangeable.[1]
Does clinical research prove that injected glutathione improves energy or recovery?
The cited Hauser study does not establish energy or recovery benefits for this product.[1] A randomized pilot trial by Hauser et al. investigated intravenous glutathione in Parkinson's disease patients and found no statistically significant difference in symptom improvement compared to placebo.[1] Those study results do not substantiate wellness, detoxification, or athletic performance claims in healthy individuals.[1]
Why did the Food and Drug Administration issue an ingredient warning regarding glutathione?
The Food and Drug Administration (FDA) warned compounders against using dietary supplement-grade glutathione in injectable preparations.[2] FDA describes adverse-event reports consistent with endotoxin exposure after use of supplement-grade ingredient from a particular supplier.[2] The notice recommends checking ingredient source with the compounder.[2]

Regulatory Context and Safety Disclosures
FDA described reported reactions including fever, chills, dizziness, pain, shock and sepsis-like symptoms.[2] FDA said the reactions were consistent with endotoxin exposure.[2]
Compounded medications are not FDA-approved.[5] FDA does not verify the safety, effectiveness or quality of compounded drugs before marketing.[5]
