I think pinning it is better. Here's what some AI thingy says:
Oral glutathione doesn't absorb well 'cause your stomach breaks it down. Some studies say it can raise blood levels a little, but not enough to matter. Liposomal or sublingual might work better, or injecting it.
Enzymes eat it up: Glutathione is a tripeptide, and enzymes in the gut break it down before it gets into your blood.
Poor Absorption: Even if it stays whole, it doesn't always get into the bloodstream.
Better options:
Liposomal: Wrapped in liposomes to protect it.
Sublingual: Under the tongue, straight to the blood.
IV: Straight into the blood.
Boosting pills:
Vitamin C: Helps recycle glutathione.
Healthy Fats: Might help absorption.
Precursors: Like NAC, to help your body make it.
Overall, pills aren't great because they don't absorb well.
