Key Benefits and Actions*

  • Soy-free liposomal format with supportive nutrient cofactors
  • May help support the body’s healthy free-radical defenses
  • May help support liver health
  • May help support a healthy immune system

Optimal Liposomal Glutathione Plus by Seeking Health provides 350 mg of reduced glutathione per serving, along with vitamins and minerals that are essential for the body’s glutathione recycling process. Glutathione is an important antioxidant that is naturally found in every cell in the body, providing protection from free radicals and peroxides. Within the body, glutathione is produced from three amino acids: L-cysteine, glycine and L-glutamic acid. Glutathione is also present in many dietary sources, though its amino acid precursors are more abundant in foods. This antioxidant is essential in helping the body’s cellular defenses and immune system function at full capacity.*

Glutathione is present in the body in two forms: reduced and oxidized. The oxidized form can be recycled and converted back into the reduced form via important enzymatic reactions within the body. This oxidation-reduction cycle requires certain vitamins and minerals as cofactors, such as riboflavin and selenium. Molybdenum is involved in sulfate-sulfite conversion, a process that can affect glutathione levels if not functioning efficiently. Optimal Liposomal Glutathione Plus includes these complementary nutrients to support healthy glutathione levels.*

In the body, glutathione acts as a cell protectant. It may be involved in helping to maintain normal protein structures within the body, marking certain molecules for elimination as waste in the liver, and in important enzymatic reactions needed for neutralizing potentially damaging free radicals throughout the body. It may support detoxification pathways and healthy functioning of the liver, kidneys, lungs, and intestinal tract.*

Optimal Liposomal Glutathione Plus uses a unique liposomal delivery method to support optimal absorption of this reduced glutathione and help to protect the fragile molecule through the digestive tract. A liposome is a tiny phospholipid vesicle that mimics the body’s own cell structure. Liposomes may be better absorbed across cell membranes in a way that is not possible for ordinary water-soluble or fat-soluble nutrients. Our liposomes are composed of non-hydrogenated phospholipids, derived from GMO-free sunflower oil. This is a soy-free product.*

Not sure yet

I’ve only been using this a few weeks and only every few days. It tastes awful. I haven’t noticed any negative effects so I’ll stick with it.
