What is glutathione?
Glutathione is a molecule made from three amino acids, produced naturally in nearly every cell of your body. It's often called the body's "master antioxidant" for the central role it plays in your natural defense system — helping protect cells from oxidative stress.* The "reduced" form (L-glutathione reduced) is the active, ready-to-work state your body uses to help neutralize free radicals.
What is oxidative stress — and why does it matter?
Every day, your body is exposed to free radicals — unstable molecules produced by intense training, environmental factors, and everyday metabolism. When free radicals outpace your body's defenses, the result is oxidative stress. Antioxidants like glutathione help counter this by supporting your body's natural ability to neutralize free radicals.*
What does a glutathione supplement do?
Supplementing with L-Glutathione may help support antioxidant activity throughout the body. It's designed to support:*
- Cellular health and recovery — supporting your cells day to day*
- Neutralizing free radicals from exercise, stress, and the environment*
- Overall wellness and vitality — supporting how you feel and function*
Why athletes and active people use glutathione
Intense training is one of the biggest everyday sources of oxidative stress. Many active people add antioxidant support to help protect cells from the oxidative stress that comes with hard training, environmental exposure, and daily life — and to support their natural recovery process.*
