False

It is true that athletes (endurance and weight lifting) need a bit more protein than a sedentary person, however this need can easily be met by consuming a well balanced diet.

The main sources of protein are meat and alternates such as poultry, fish, eggs, legumes, tofu, and peanut butter. Milk, yogurt and cheese also contribute protein to the diet. As long as athletes meet the recommended intake of 2-3 servings of meat and alternates and 2-4 servings of milk products (adult recommendations from Canada's Food Guide to Healthy Eating) they should be meeting their needs.

Protein supplements generally are a poor investment. If you consume more protein than you body needs, it will be stored as fat. And the extra protein may not be leaving enough room for all the carbohydrates that provide energy for endurance and weight training. Too much protein also increases the risk of dehydration.

So instead of turning to protein supplements, visit a Registered Dietitian or nutritionist to help plan a winning diet.
