Creatine Loading Timeline: Loading vs Low-Dose
Studies show two ways to raise muscle creatine by about 20%: a short loading phase or a lower daily dose taken for longer.1 This tool shows when each protocol, as used in research, typically reaches that point from your start date, and flags the body mass change if you have a weigh-in coming.
Two protocols, same end point
Both protocols reach a similar rise in muscle creatine; loading gets there in about a week, the low-dose approach in about four weeks.1,3 My creatine article notes that the low-dose approach may suit athletes who want to avoid a rapid jump in body mass or divided high doses.2
Safety
The 2017 ISSN position stand concluded that short- and long-term supplementation, including studies of up to 30 g/day for 5 years, is safe and well tolerated in otherwise healthy individuals; this is not a recommendation to use high doses.6
