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.
A healthy adult vegan can consume as much as 5 grams daily. If you are suffering from any of the disease states listed above, check with your doctor first for proper dosing, which can be as high as 5-10 grams. Creatine is not recommended for children under the age of 18 or for anyone with kidney or liver disease.
