Your body’s masterantioxidant.

Glutathione is a tripeptide — a small molecule made of three amino acids: cysteine, glycine, and glutamic acid. It is produced naturally by the liver and is present in every cell in the human body. Glutathione is often referred to as the body’s “master antioxidant” because of its role in neutralizing free radicals, recycling other antioxidants, and supporting detoxification pathways.

No. Compounded injectable glutathione is not FDA-approved as a finished drug product. The FDA does not evaluate compounded medications for safety, effectiveness, or quality. The FDA has specifically warned against injectable glutathione products from unregulated sources. Rylo’s glutathione is prepared by a licensed US compounding pharmacy and requires a prescription from a licensed provider.

Oral glutathione has limited bioavailability — it is largely broken down during digestion before reaching the bloodstream. Injectable glutathione bypasses the digestive system, delivering the compound more directly. However, this route also carries different risks than oral supplementation, including injection site reactions and, in rare cases, more serious adverse events. Your provider will help determine the most appropriate form for you.

Common side effects include mild nausea, headache, and irritation at the injection site (redness, swelling, or soreness). Less common side effects may include diarrhea, flushing, or temporary stomach discomfort. Serious allergic reactions are rare but possible. The FDA has documented cases of adverse events with injectable glutathione from unregulated sources. Always use glutathione from a licensed pharmacy under medical supervision.

Glutathione plays several roles in cellular function: it neutralizes reactive oxygen species (free radicals), supports Phase II liver detoxification, helps recycle other antioxidants like vitamins C and E, and is involved in immune cell function. Glutathione levels naturally decline with age, stress, poor nutrition, and environmental toxin exposure. Research into supplementation is ongoing, and clinical evidence for specific health claims remains limited.

Individual responses vary significantly. Some patients report feeling more energy or noticing changes in skin appearance within a few weeks of consistent use. However, clinical evidence for specific timelines is limited, and results are not guaranteed. Your provider will monitor your response and adjust your protocol accordingly.

Injectable glutathione is not recommended for individuals who are pregnant or breastfeeding, have a known allergy to glutathione or any of its components, or have certain liver conditions. Always disclose your full medical history and current medications to your provider before starting treatment. Your provider will determine if glutathione is clinically appropriate for you.
