Green Tea "Blocks" Beta-Blocker --
A new study shows that drinking green tea can drastically reduce the amount of a beta-blocker (nadolol, Corgard) absorbed into the bloodstream. Beta-blockers are typically taken to lower blood pressure, raising concern for people using green tea along with this beta-blocker and, possibly, related medications. Get the details, along with our tests of green tea drinks and supplements, in the update to the Green Tea Review >>
If you take a beta-blocker (which includes the popular drugs metoprolol (Lopressor, Toprol) and propranolol (Inderal)), be aware that chromium
may offer benefits. These interactions are explained in the Beta Blockers
article, which is part of the extensive Drug Interactions
section of our website (where you can look up interaction for other drugs you may be taking).
