milquetoast · Jul 22, 2010

Some heavy metals and such. Arensic, lead, cadmium and mercury were tested by Consumer Reports.

Here are the average amounts of metals we found in three servings of these protein drinks. The maximum limits for them in dietary supplements proposed by the U.S. Pharmacopeia are: arsenic (inorganic), 15 micrograms (µg) per day; cadmium, 5 µg; lead, 10 µg; mercury, 15 µg. Amounts at or exceeding those limits are in bold. Experts said three servings a day is common.

While a lot of people are criticizing the results due to lack of stated methodology, etc, it still highlights that protein supplements shouldn't be overdone.
