A study recently concluded at the University of Montreal in Canada and reported by MedicalNewsToday.com reveals that protein supplements are overused and show little to no impact on athletic performance.

Martin Fréchette, a University of Montreal graduate and researcher in the school's Department of Nutrition, studied 42 athletes from various sports along with their nutrition habits and supplement use. Not only did most of the athletes in the study have little to no knowledge of the role of protein supplements, 70 percent admitted that they didn't think their performance would suffer if they quit using the products. The researcher also found that there is little to no data available about any benefits protein supplements provide.

"No less than 81 percent of athletes taking supplements already had sufficient protein from their diet," said Fréchette. What's more, he said, consumers of supplements had levels of sodium, magnesium, niacin, folate, vitamin A and iron that exceeded the acceptable norms.

"This makes them susceptible to health problems such as nausea, vision trouble, fatigue and liver anomalies," said Fréchette. He stresses that supplements come with certain risks. "Their purity and preparation aren't as controlled as prescription medication," he said. "Sports supplements often contain other ingredients than those listed on the label. Some athletes consume prohibited drugs without knowing."

Other studies have shown that 12 to 20 percent of products regularly used by athletes contain prohibited substances. Fréchette observed a particular interest by the athletes on the efficiency, legality and safety of those drugs. Still, nine athletes out of 10 reported using food supplements on a regular basis. They reported that they consume an average of 3.35 products: energy drinks, multi-vitamins, minerals and powdered protein supplements.

Fréchette found their knowledge of food supplements to be weak. "The role of proteins is particularly misunderstood," he warned. "Only one out of four consumers could associate a valid reason, backed by scientific literature, for taking the product according."

Before starting a supplement regimen, it's a good idea to research the various products and consult with a trainer before beginning use. It's also important to note that many ‘reputable' supplements have proven to be not only effective, but completely safe as well. A fitness professional or trainer can assist individuals in finding which protein supplement, if any, is right for their level of activity and personal fitness goals.
