Glutathione—the body's master antioxidant for cellular defense—may be the key to good health, long life and sustainable vitality.* While a small amount of glutathione comes from our diets, most is produced in the body from individual amino acids derived from protein. As we age, however, we lose much of our ability to break down protein and form glutathione from individual aminos. Supplements are a great way to help maintain those healthy levels. All Swanson Glutathione products feature advanced Setria® Glutathione, a "reduced" form your body can recognize and readily absorb. And with our new high potency capsules, optimum antioxidant supplementation is easier than ever.
