A creatine loading phase is optional and primarily useful for rapidly increasing tissue saturation, such as in specific military protocols requiring quick readiness.

“loading will get you so really what you're looking to do is saturate your phosphor creatin stores in your muscle cell and you can do that through loading or you can do it through maintenance phase if you do it through loading it'll saturate in five to seven days if you do it through maintenance it'll take about 3 to four weeks”

“it's really I guess if you were somebody who'd never taken it before and you've got like a big athletic event coming up and you really want to be on it for it that could make sense”

“While a “loading dose” was once recommended, most experts don’t think this is necessary.”

“in 1992 uh Roger Harris came up with a seminal uh um um protocol where you just mentioned this loading phase it's the most viable rapid way to really saturate your skeletal muscle this has nothing to do with the bone or the brain and so that's 20 grams a day for about 7 days is usually what's recommended uh a bit of new information you only need to do that for two days and then your muscles are saturated”
