Pharmacokinetics Clinical Trial
Official title:
Pharmacokinetic Profile of N-Acetyl Cysteine in Self-reported Healthy Men and Women
The study compares three different formulations containing N-Acetyl Cysteine, with regards to acute absorption over a 24-hour period, following single ingestion. The formulations are traditional N-Acetyl Cysteine, N-Acetyl Cysteine Ethyl Ester, and a product containing a combination of N-Acetyl Cysteine Ethyl Ester, glycine, and two minerals with antioxidant potential (selenium and molybdenum) that might enhance the effect of N-Acetyl Cysteine Ethyl Ester. Subjects will report to the lab on three different occasions to consume the products, using a randomized cross-over design, and blood will be collected periodically (for the initial 8 hours and then again at 24 hours) per standard, routinely used pharmacokinetic /pharmacodynamic study protocols for evaluation of circulating glutathione concentrations. The hypothesis for this study is that the combination of N-Acetyl Cysteine Ethyl Ester + glycine will yield the greatest increase in glutathione, followed by N-Acetyl Cysteine Ethyl Ester, followed by N-Acetyl Cysteine. These findings will provide initial evidence specific to the bioavailability of these treatments following a single acute ingestion and may guide future recommendations regarding routine use.
One method of enhancing the uptake of N-Acetyl Cysteine following oral ingestion is to use the ethyl ester form, referred to as N-Acetyl Cysteine Ethyl Ester, which exerts remarkable antioxidant potential . N-Acetyl Cysteine Ethyl Ester is also available as a dietary supplement, has been well-investigated and known to be much more effective than traditional N-Acetyl Cysteine, in terms of elevating glutathione levels. In addition, recent work indicates that inclusion of the amino acid glycine along with very high dose N-Acetyl Cysteine results in an increase in glutathione, which may have health enhancing benefits for a variety of conditions. Such an elevation in glutathione may provide for antioxidant benefits which can reduce oxidative stress and possibly aid various aspects of overall health, as oxidative stress is associated with disease and aging.
