Depending on the condition being investigated, symptoms may include fatigue, night sweats, unexplained weight loss, jaundice, or abnormal bruising
The field shows growing interest in novel delivery systems, including liposomal formulations, sublingual preparations, and buccal absorption methods, attempting to overcome the documented challenges of glutathiones poor gastrointestinal bioavailability
