Benefits Glutathione exists in two primary states in the human body: Reduced (GSH) and Oxidized (GSSG). Reduced Glutathione is the "active" state possessed of an extra electron that neutralizes free radicals, protects cell membranes, and supports liver health.* Once glutathione neutralizes a free radical, it becomes "oxidized" (spent) and must be converted back by the body to function again. Reduced L-Glutathione skips that conversion, supplying your cells with supplemental antioxidant support.* *These statements have not been evaluated by the Food and Drug Administration.

Great Glutathione

I’ve been taking this L-Glutathione and the quality is top-tier for the price. The main ingredient is the "reduced" form, which is a huge benefit for absorption compared to cheaper versions. The 120 capsule size is great because it lasts four months, and the package is sturdy and well-sealed. I’ve noticed a real improvement in my skin clarity and a brightening effect that I didn't get from other brands. It’s a simple, high-potency supplement that offers a solid protective benefit for your daily routine

L glutathione reduced

I highly recommend this product for people with ME/CFS (and others of course) because we naturally have lower glutathione in our body's. I Have used this for many years and the quality is very good, the tablets size nice and potency is high. Good packaging. Helps reduce free radicals and oxidative stress. Taste nothing.

Someone recommended this to me to lighten the skin. I tried it twice and didn’t see any difference. Quality seems good. Ingredients I don’t know. Size of the capsule is normal. Packaging is done well. It doesn’t have any taste. Benefits I didn’t see any. It is veggie so that is a plus.

Recommend it for dark skins

California Gold Nutrition’s Reduced Glutathione 500mg is one of the products that I keep on ordering from iherb. Just right fit for my age as I’m near 40s. Packaging is good. It not too expensive plus it’s vegetarian/vegan so it’s good for diet. It’s a powerful antioxidant that contains free radicals and keeps my immune system strong. I highly recommend this product. Glutathione is an antioxidant found naturally in your body. Also known as GSH, it is produced by the liver and nerve cells in the central nervous system and is made from three amino acids: glycine, L-cysteine, and L-glutamate. Glutathione can help metabolize toxins, break down free radicals, support immune function, and more.

I liked this product and felt like it was high quality. I upgraded to a new supplement drink that has a full amino acid profile so I don’t need anymore. Or would re order.

Disappointing Packaging

Disappointing Packaging The item arrived safely, but the packaging was very disappointing. It didn’t feel secure or well-presented and wasn’t what I expected. Better packaging would help protect the item and create a much better first impression. I hope more care is taken with packaging in the future.
