KAL® L-Glutathione SR 500mg is a powerful antioxidant in a sustained-release vegetarian capsule. L-Glutathione is a common free peptide found in the body, which is formed by combining three amino acids: glutamine, glycine, and cysteine. As an antioxidant, it helps tackle free radicals in the body which can lead to oxidative stress.* Oxidative stress happens when there’s an imbalance in the production of free radicals and the body’s ability to fight them off. L-Glutathione also plays an active role in supporting healthy liver function, therefore helping to support the normal elimination of toxins in the body.* Additionally, it offers nutritive support for normal, healthy immune system response.* Our L-Glutathione comes in a sustained-release capsule, so it can slowly release in the body throughout the day. As always, you can trust KAL to bring you powerful supplementation and high-quality ingredients that are lab verified in-house for potency and purity—that’s our promise to you.
