The Master Antioxidant Your Liver Can't Make Enough Of

In this Supplement Ingredient Series episode, Nurse Doza breaks down glutathione — the master antioxidant your liver makes to fight inflammation, detox your body, and protect your brain. With roughly 1 in 4 people worldwide carrying a fatty liver, most are running on low reserves. Learn why glutathione is non-negotiable for energy, performance, and recovery — plus how to get your own vial to use at home. Featured Partner: SHED SHED delivers practitioner-grade glutathione in a vial you can use at home — the same master antioxidant Nurse Doza has administered through thousands of injections and IVs in clinical practice. Because the liver's ability to produce glutathione drops when it's fatty, inflamed, or overworked, supplementing directly is often the fastest way to restore energy, mental clarity, and detoxification pathways — exactly the mechanism discussed in this episode. 👉 Get your SHED glutathione vial here: https://tryshed.com 👉 Use code DOZA30 at: https://tryshed.com 5 Key Takeaways Glutathione is your body's master antioxidant. It's a tripeptide made in the liver that neutralizes free radicals, recycles other antioxidants like vitamin C and E, and powers detoxification pathways throughout the body. Your liver is the glutathione factory. Peer-reviewed research confirms the liver is the central hub for glutathione production and systemic distribution — when hepatic function drops, so does your antioxidant defense system. Fatty liver compromises antioxidant production. Global NAFLD prevalence estimates range from roughly 25–32% of adults, meaning a significant portion of the population has reduced capacity to make glutathione — which is exactly when fatigue, brain fog, and chronic inflammation start showing up. Oral glutathione has poor bioavailability. Because glutathione is broken down by enzymes in the digestive tract, injections and IVs bypass digestion and deliver the molecule directly into circulation — which is why Nurse Doza and many functional practitioners prefer this route. Glutathione isn't just a detox tool — it's a performance tool. Higher glutathione levels are clinically linked to better energy, sharper cognition, faster recovery, and lower systemic inflammation. That's why it's a cornerstone ingredient in Nurse Doza's practice.
