Attenuation of Sound Waves. When sound travels through a medium, its intensity diminishes with distance. In idealized materials, sound pressure (signal amplitude) is only reduced by the spreading of the wave. Natural materials, however, all produce an effect which further weakens the sound.
There is no established dose. Many different dosages of creatine supplements have been used in studies. For athletic performance, some people start with 10 grams to 30 grams of creatine a day. This is followed by a maintenance dose of 2 grams to 5 grams of creatine a day. Natural food sources of creatine include meat, poultry, and fish.
Typically, you take only 5 grams at a time. If you're in a loading phase, space your 5 gram servings evenly throughout the day. Competitive bodybuilders vary dramatically in the timing of their creatine consumption. Ideal times are before and after a workout! The reason for the varied timing of taking creatine is that it works almost any time of day. Just as it takes a week to load up in your system, one study showed it remained effective even for several weeks after stopping creatine. So take it when it's most convenient for you.
