Clinical Trials and the Link to Device Development Drug delivery is often inseparable from the therapy itself
Regardless of whether you consume a triple cheeseburger or a supplement, it is natural to question any potential negative effects on your body
A clinical study involving 8 participants showed that 250mg of glucosamine administered for 8 weeks increased the expression of type I and III collagen and hyaluronan synthase.48 In a blinded RCT (n=53), a dietary supplement containing glucosamine, minerals, and antioxidants significantly decreased the number of facial wrinkles and fine lines.49 Systemic Glutathione Glutathione has antioxidative, antitumor, antiviral, and antimelanogenic properties.50 Oral and intravenous formulations have been used to decrease skin pigmentation and photoaging, but 2 recent systematic reviews of the literature, including 3 RCTs, did not find sufficient evidence to recommend their use in this setting.50,51 A more recent RCT (n=124), not included in the above systematic reviews, showed that 250mg of glutathione combined with 500mg of l-cystine for 12 weeks significantly reduced solar lentigines and hyperpigmented macules in Asian women
Yet these same pathways create problems elsewhere
