Also discard if the solution appears cloudy, contains particles, has been left at room temperature for more than 48 hours, or is past the 28-day mark
Studied in oxidative stress, antioxidant response, cellular defense, and glutathione-dependent pathway models
The main differences include FDA approval, dosing consistency, manufacturing standards, and medical oversight
