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.
Creatine is a natural substance that turns into creatine phosphate in the body. Creatine phosphate helps make a substance called adenosine triphosphate (ATP). ATP provides the energy for muscle contractions.The body produces some of the creatine it uses. It also comes from protein-rich foods such as meat or fish.art of the reason for creatine's popularity might be its accessibility. Creatine powder, tablets, energy bars, and drink mixes are available without a doctor's prescription at drug stores, supermarkets, nutrition stores, and over the Internet.
