Summary

This study looked at whether a liposomal coating helps the body absorb more vitamin C and glutathione from a liquid supplement. Twenty healthy adults took both a regular and a liposomal version, and their blood levels were measured over 8 hours. The goal was to see if the liposomal technology improves absorption.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Vitamin C and Glutathione (liposomal and non-liposomal forms)
What this could lead to
If liposomal technology boosts absorption, it could lead to more effective vitamin C and glutathione supplements.
What could go wrong
This is a very small, early-stage study in 20 healthy adults, so results may not apply to the general population or people with health conditions.
