Homocysteine reduction: NAC has been shown to lower plasma homocysteine levels by 11.5% at a dose of 1,800 mg/day in patients with hyperhomocysteinemia, likely through a disulfide exchange reaction (Ventura et al., Pharmacology, 2003) [66]
Liposomal glutathione exists as a compound that researchers developed by enclosing glutathione within liposome particles, which protect the substance during its time in the human body
Why the caution
Liposomal Delivery: Enhanced Absorption: Liposomal formulations are designed to encapsulate glutathione, improving its absorption in the digestive tract and potentially increasing bioavailability
Similarly, oral glutathione supplements have historically been considered poorly bioavailable, though newer formulations (liposomal, sublingual, S-acetyl) aim to improve this [1][12]
If you plan to take in between meals, then make sure to keep at least 2 hours of time gap
