  1. Dietary Supplements are products that are sold to supplement the diet and provide naturally occurring vitamins, amino acids and other nutrients commonly found in our food. They are legal and can be bought at Health food outlets and even drug stores in Canada

    Dietary supplements

  2. Do Supplements Work?? They are generally considered safe but it is questionable about how valuable they are in building fitness since a proper diet can provide the same nutrients. Most of the claims by company’s who manufacture supplements are not backed up by the research done on them. In fact, a lot of the research shows athletes who use supplements have no significant improvement in fitness compared to those eating a balanced diet. The ingredients in supplements are found naturally in food.
  3. Are they worth the money?? Like a sponge that can only absorb so much liquid, the body can only absorb so many nutrients at a time. Taking mega doses such as found in most supplements, results in much being wasted. A proper diet can provide the amount of nutrients needed to train in most cases.
  4. The terms steroids, “roids” or “juice” usually refer to anabolic steroids, which are synthetic (man-made) substances similar to the male sex hormone testosterone. The term “anabolic” refers to muscle growth. Anabolic steroids combined with intense training, can produce an increase in muscle mass and physical strength enhancing sport performance. Users typically take a pill form or use a hypodermic needle to inject steroids directly into the blood stream. Some may come in a cream that is applied directly on the skin.

Athletes who compete clean are at a disadvantage and may feel pressure to do roids to even the playing field. Most sports amateur and pro sport organizations have rules that ban steroid use.
