🔬Recovery & Adaptation

L Glutathione Reduced

L-glutathione (reduced) is a potent antioxidant that helps protect cells from oxidative stress, supporting recovery and adaptation.

What Does L-Glutathione Reduced Do?

L-Glutathione is often referred to as the body's "master antioxidant." In the context of a pre-workout, the reduced form is used to combat the oxidative stress generated during high-intensity training, facilitating faster adaptation and recovery.

  • Oxidative Stress Reduction: It directly neutralizes reactive oxygen species (ROS), protecting muscle cells from the damage that occurs during heavy lifting.
  • Nitric Oxide Potentiation: When combined with L-Citrulline, it helps prevent the breakdown of nitric oxide, leading to longer-lasting muscle pumps and better nutrient delivery.
  • Enhanced Recovery: By mitigating the inflammatory response immediately after exercise, it helps reduce delayed onset muscle soreness (DOMS) and systemic fatigue.
  • Cellular Adaptation: It supports the body’s ability to adapt to training stimuli by maintaining a healthy redox balance within the muscle tissue, ensuring you're ready for your next session.

Clinical vs. Gym Bro Dosing

TierDoseNotes
Threshold100mgBasic antioxidant maintenance and general health support.
Clinical250mgThe standard dose for recovery and performance support.
Performance500mgOptimized for synergistic pump effects when stacked with Citrulline.
High1,000mgMaximum daily intake typically seen in clinical studies for detoxification.

Key Insight: While 250mg is the recommended clinical dose for recovery, the real magic happens when you stack L-Glutathione with 2-8g of L-Citrulline. Research suggests this specific combination sustains nitric oxide levels significantly longer than taking Citrulline alone, extending your pump well into the post-workout window.

Side Effects & Warnings

  • Digestive Issues: Some users may experience mild stomach upset, bloating, or cramping, especially if taken on an empty stomach.
  • Sulfur Smell: Because glutathione contains sulfur, high doses can occasionally cause a temporary sulfurous odor in breath or sweat.
  • Zinc Interference: Chronic, very high-dose supplementation (over 1,000mg) may potentially impact zinc absorption over time.

Tip: Always ensure you are using the "reduced" form of L-Glutathione. The non-reduced (oxidized) form is poorly absorbed by the human digestive tract, making it largely ineffective for performance purposes. Look for branded versions like Setria for maximum bioavailability.
