Ingredients: Water, Betaine, Diglycerin, Butylene Glycol, Niacinamide, 1,2-Hexanediol, PEG-60 Hydrogenated Castor Oil, Lilium Candidum Callus Culture Extract, Carbomer, Arginine, Ethylhexylglycerin, Adenosine, Sodium Hyaluronate, Disodium EDTA, Hydroxyethylcellulose, Malt Extract, Glycerin, Prunus Persica (Peach) Fruit Extract, Crataegus Cuneata Fruit Extract, Xanthan Gum, Pyrus Communis (Pear) Fruit Extract, Dipotassium Glycyrrhizate, Magnolia Officinalis Bark Extract, Musa Sapientum (Banana) Fruit Extract, Hedera Helix (Ivy) Extract, Vanilla Planifolia Fruit Extract, Rosa Damascena Callus Culture Extract(30ppm), Glycine Soja (Soybean) Oil, Phosphatidylcholine, Fructan, Caprylyl Glycol, Hydrogenated Lecithin, Palmitoyl Tripeptide-5, Sodium Phosphate, Sodium Ascorbyl Phosphate, PEG-40 Hydrogenated Castor Oil, PPG-26-Buteth-26, Polysorbate 20, Lecithin, Palmitoyl Tetrapeptide-7, Acetyl Octapeptide-3, Palmitoyl Pentapeptide-4, Palmitoyl Tripeptide-1, Acetyl Hexapeptide-8, Copper Tripeptide-1

Largest reductions (18-20%) occurred in the high-dose group after 1 and 2 weeks Combined dose groups significantly reduced the ratio by 14% after 1 and 2 weeks The decreases observed in oxidized:reduced GSH as a result of oral liposomal GSH supplementation are likely indicative of a general systemic reduction in oxidative stress levels. Plasma levels of 8-isoprostane (a marker of oxidative stress) decreased after liposomal glutathione supplementation

Mean values are based on one kitten per replicate, seven replicates in CON, and six replicates in LMSM and HMSM on d 0

The experiments were conducted independently at least three times
