I keep a little fridge log for supplements because I like fewer unknowns, and this one is annoying me. My glutathione went from clear to faintly hazy between day 2 and day 6 in the cold. Seal intact, no floaters, temp bouncing between 37–39°F. It did not freeze. I flipped it upright, gave it a gentle swirl, and it stayed uniform-ish, just not crystal clear. My systems brain wants a rule: clear = fine, cloudy = discard. My practical brain says oxidation, humidity, and temperature swings are all variables, and one week is not a lot of data. I’m not looking for a verdict, just a reality check: if you’ve stored glutathione before, did yours ever go slightly cloudy and then clear up, or is that a hard stop for you?
