Absolutely. Athletic Greens is tested thoroughly for heavy metals.
Every single batch is tested twice: once at the time of manufacture and again at the time of packaging.
In addition to the testing performed on every batch, once a year we take that testing one step further and do an even more extensive audit which includes testing for heavy metals.
And finally, Athletic Greens is NSF Certified, which means that an independent third party (NSF International) has tested our product to ensure there are no unsafe levels of heavy metals and other contaminants.
