So how much protein is enough? A lot depends on your activity levels.

Amino acids are necessary for the development and maintenance of our muscles and many organs. How hard we work these areas will effect how much amino acids we need. For most people, 25 to 35 grams of protein are adequate to handle our needs. Men, who generally have a higher percentage of muscle then women, generally need a bit more.

People who are physically active need more. In particular, athletes who take part in stressful workouts need a lot more to help their bodies in general, and muscles in particular, to recover. The greater the stress on the muscles and organs the more protein, and amino acids, you need.

For instance, body builders taking part in very stressful workouts may need as much as a gram of protein for each pound of their body weight. At such high activities, amino acids supplements are a great idea.
