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.
The remainder of the creatine in your body comes from dietary sources. Good dietary sources of creatine include wild game, lean red meat and some fish including tuna, herring and salmon. Approximately 2 to 3 pounds of raw meat or fish contain the equivalent of 5 grams of pure creatine. Cooking will break down creatine, leaving it less available for your body to absorb it.
