EGCG simply slows the clearance of naturally circulating norepinephrine a far gentler mechanism that elevates metabolic rate without triggering the cardiovascular stress response associated with stimulants
Adjustments were made for individual traditional cardiac risk factors (age, gender, diabetes mellitus, systolic blood pressure, former or current cigarette smoking, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol), extent of CAD, left ventricular ejection fraction, history of MI, baseline medications (aspirin, statins, -blockers, and ACE inhibitors), and renal function by estimated creatinine clearance
While glutathione injections are popularly marketed for skin brightening and anti-aging benefits, there are no proven clinical trials confirming their effectiveness for such cosmetic purposes
