Protein drinks are a simple and effective way to replenish vital amino acids stores, especially on training days, as well as a good way to add a little extra protein to your diet to help build and maintain lean muscle mass. However, you might want to take a closer look at your favorite product.
June 3, 2010 — Popular protein drinks with names like Muscle Milk and EAS Myoplex — favorites of teens, gym rats, boomers, and pregnant women — can contain potentially unsafe levels of heavy metals and other harmful substances, according to an investigation by Consumer Reports.
”Consuming these kinds of protein drinks on a regular basis can in some cases create the risk of chronic exposure, even at low levels, to heavy metals such as cadmium and lead that can pose health problems, particularly to vulnerable people,” says Andrea Rock, the Consumer Reports editor for the investigation. Among vulnerable people are children under age 18, pregnant women, and people with diabetes or chronic kidney conditions, she says.
Lab Tests on Protein Drinks
For the study, Consumer Reports had an independent laboratory test 15 protein drinks, including ready-to-drink formulas and powders meant to be mixed with milk, juice, or water. Three servings of the products tested provide from 27 to180 grams of protein.
Testing for contaminants — including arsenic, cadmium, lead, and mercury — found most products to be in the low to moderate range. But three products cause concern, Rock says, because people who have three servings a day could be exposed to higher levels of three substances — arsenic, cadmium and lead. Some products surpass the maximum limit proposed by the U.S. Pharmacopeia (USP). The USP sets voluntary standards for health products.
Consumer Reports says these three products are of special concern:
- EAS Myoplex Original Rich Dark Chocolate Shake has an average of 16.9 micrograms of arsenic in three servings — more than the 15 micrograms a day that is the proposed USP limit. It has an average of 5.1 micrograms of cadmium for three servings — above the USP limit of 5 micrograms a day.
- Muscle Milk chocolate powder, at three servings, contained all four of the metals, and three metals were found at a level that was among the highest of all 15 products tested. Cadmium levels were 5.6 micrograms — above the 5-microgram limit. Lead was 13.5 micrograms — above the USP limit of 10 micrograms. The arsenic averaged 12.2 micrograms — near the 15-microgram daily USP limit.
- Muscle Milk vanilla crème had 12.2 micrograms of lead per three servings — above the 10-microgram daily limit. It has 11.2 micrograms of arsenic — close to the 15-microgram daily limit.

When dermatologists treating you for skin cancer warn you about not getting enough sun for fear of not getting enough vitamin D, you know something is up. Read on…
Long considered just a supplement consumed with calcium for bone health, this humble vitamin may have untapped potential in fighting or preventing disease, suggests an explosion of new research. Not only has it shown promise in reducing the risk of, among other things, diabetes, pancreatic cancer, breast cancer and cardiovascular disease, but it also seems to improve infertility, weight control and memory…
Next week, hope and hype may collide. An Institute of Medicine committee will convene in Washington to discuss whether the recommended daily intake of vitamin D and calcium should be increased. There, researchers overwhelmed by the vitamin’s potential will square off against skeptics who say much more study is needed before people are urged to take vitamin D supplements. Getting the newly suggested amounts would be difficult otherwise…
Some researchers are advocating at least 600 IU a day, with an upper limit of 10,000 IU. Giving impetus to this push are the facts that many people seem to be deficient and that the nutrient appears to play a role in many conditions…
Vitamin D has long been known to be crucial to bone and muscle health by improving calcium absorption in the intestines and the way calcium is regulated in bones.
More recent research shows that receptors for it are found in almost every organ and tissue system in the body, suggesting that deficiencies may affect many types of cell functions.
When exposed to sunlight, the skin makes the vitamin, but not everyone spends the five minutes a day or so outside that is necessary for synthesis — and many more people today wear sunscreen to prevent skin cancer…
The July issue of the Annals of Epidemiology(09)X0007-4, devoted to vitamin D research, links the vitamin to lower risks of cancers of the breast, colon, ovaries and prostate. Animal and lab studies also demonstrate its importance in many of the cellular mechanisms that control cancer, such as cell growth, cell death, inflammation and DNA repair…
