Glutathione Master Antioxidant Therapy

Glutathione is a tripeptide (glutamate, cysteine, glycine) that your body produces in every cell. It's your primary antioxidant — neutralizing free radicals, supporting liver detox, and maintaining immune function. Levels naturally decline with age, oxidative stress, and illness.

Oral glutathione is broken down in the digestive tract before it can be absorbed into the bloodstream. Subcutaneous (SQ) delivery bypasses this degradation, achieving near-complete bioavailability and directly replenishing cellular glutathione pools.

Glutathione (200 mg/mL) is sold as a 1-month plan (10 mL, $169 one-time or $143.65 with auto-refill) or a 3-month plan (30 mL, $349 one-time or $296.65 with auto-refill) — the 3-month plan saves $158 vs. three 1-month orders. That is what ships and what you pay — your provider sets your dose when they write the prescription, so how long a plan lasts depends on the dose they prescribe. Auto-refill is optional, takes 15% off either plan and cancels anytime; free syringes, alcohol prep pads and cold-chain shipping are included on both.

Many patients report improved energy and skin tone within 4–8 weeks, with optimal antioxidant and skin benefits typically emerging around 8–12 weeks of consistent dosing. Immune and antioxidant effects are harder to measure subjectively but build over time. Individual results vary based on baseline glutathione levels and lifestyle factors.

Glutathione is a naturally occurring compound in the human body. Subcutaneous glutathione has a strong safety profile in clinical use. As with any injectable therapy, a licensed provider evaluates your health history before prescribing. Side effects are rare and typically mild.

Most people tolerate glutathione very well. When side effects do happen they're usually mild and short-lived — most often temporary nausea, dizziness, or a mild headache, plus some redness or stinging at the injection site. Allergic reactions are rare. Because glutathione can occasionally trigger wheezing, it isn't prescribed for people with a history of asthma. Your provider reviews your full health history first, and you can reach the care team any time something doesn't feel right.

Glutathione isn't right for everyone. It should be avoided by anyone with a history of asthma — it can trigger wheezing or bronchospasm — and by anyone with a known allergy to any component of the formulation. It is not used during pregnancy or breastfeeding. Your Affinity provider reviews your full health history during intake and won't prescribe it if it isn't safe for you.

No — there's no need to come into a clinic. Your treatment is given at home with a small, short needle into fatty tissue (abdomen or thigh), and we walk you through every step with video guidance and education. Most patients are comfortable with the process within the first few doses.
