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.
Once muscle creatine stores are saturated, studies indicate that you only need to take 3 to 5 grams of creatine monohydrate per day in order to maintain elevated creatine stores. Most of the creatine is taken up by muscle during the first 2 to 3 days of the loading period.
