Summary
Glutathione isn't just another supplement, it's the master antioxidant your body depends on for performance, recovery, and longevity. In this episode, I break down the science behind glutathione and why I've made it part of my daily stack for nearly a decade.
We cover how glutathione neutralizes free radicals, supports detoxification, strengthens your immune system, and protects mitochondria, the power plants of your cells. You'll hear what the latest research shows about oral glutathione (yes, it works), why consistency is key, and how it directly impacts your recovery, energy, and even skin health.
I also share exactly how I use it, when I double up while traveling, how I stack it with pre-workouts for better pumps, and why I recommend fermented, clinically studied forms like CellShield.
If you want to train harder, recover faster, and slow down biological aging, this is a must-listen.
What's Discussed:
(00:04) The Importance of Glutathione Supplementation
(06:41) Beneficial Effects of Glutathione Supplementation
(11:08) Glutathione and Training Recovery
(16:53) Glutathione, Sleep, and Stress
