How much creatine to take, by bodyweight and goal

1. 01

   The maintenance dose: 3-5 g/day, every day

   3-5 g/day of creatine monohydrate is the dose carried by the bulk of the trials and endorsed by the ISSN position stand (Kreider et al. 2017). Taken daily, it saturates muscle in ~3-4 weeks and then holds saturation. There is no need to take more: once the muscle store is full, extra creatine is simply excreted in urine. This single number, 3-5 g/day, is the answer for the large majority of people and the only dose you actually have to remember.

2. 02

   Scaling by bodyweight: ~0.03 g/kg/day

   When trials scale the dose to body size they use ~0.03 g/kg/day for maintenance (Kreider et al. 2017). That is ~1.8 g for a 60 kg person, ~2.4 g for an 80 kg person, and ~3 g for a 100 kg person. Because all of those fall below 5 g, a flat 5 g/day dose covers essentially everyone with headroom, which is why most products and protocols just use 5 g. Larger or higher-muscle-mass individuals sit at the top of that range but still well under 5 g.

3. 03

   The optional load: 20 g/day for 5-7 days

   Loading means 20 g/day split into 4 doses of 5 g for 5-7 days, then dropping to the 3-5 g/day maintenance dose (Hultman et al. 1996). It saturates muscle in ~1 week instead of ~4, so the only reason to load is speed, for example before a competition or a measured training block. The trade-offs are more GI upset (cramping, loose stools) and a faster ~1-2 kg water-weight gain. Splitting the doses across the day and taking them with food reduces the GI side effects.

4. 04

   Load or not? The final store is identical

   Hultman et al. 1996 settled this directly: a group loading at 20 g/day for 6 days and a group taking 3 g/day for 28 days reached the same final muscle creatine concentration. Loading is a shortcut to saturation, not a higher ceiling. For most people there is no reason to bother: 5 g/day from the start reaches full stores in under a month with no GI penalty. Reserve loading for when you specifically need the effect within a week.

5. 05

   Timing barely matters; consistency does

   Saturation depends on total daily intake accumulated over weeks, not on any single well-timed dose, so taking creatine pre- vs post-workout makes little practical difference. The one modest signal is a small post-workout advantage when co-ingested with carbohydrate and protein, via insulin-driven uptake (Antonio & Ciccone 2013), but the effect is minor relative to simply not missing days. Pick a fixed daily habit, with breakfast or with your post-workout shake, and keep it consistent.

6. 06

   No cycling, no off-weeks

   Creatine does not require cycling. The body does not down-regulate its own synthesis to a degree that justifies time off, and stores simply decline over ~4-6 weeks if you stop (Hultman et al. 1996). Long-term daily use at 3-5 g/day is well tolerated in trials up to 5 years (Kreider et al. 2017), with no adverse effect on kidney or liver markers in healthy people. If you stop, you do not need to re-load; just resume 3-5 g/day and stores refill over a few weeks.

7. 07

   How much is too much

   There is no benefit to exceeding the saturating dose: once muscle stores are full, additional creatine is excreted, so 10 g/day produces the same muscle saturation as 5 g/day while wasting product. Very high acute doses mainly cause GI distress. The ISSN considers 3-5 g/day for maintenance and short-term loading at 20 g/day safe in healthy adults (Kreider et al. 2017). People with diagnosed kidney disease should consult a clinician before supplementing, since creatine raises serum creatinine as a benign assay artifact that can complicate kidney monitoring.

What people ask us next.

Q01

How much creatine should I take per day?

3-5 g/day of creatine monohydrate, taken every day with or without food (Kreider et al. 2017, ISSN position stand). At that dose muscle stores saturate in ~3-4 weeks. Scaled to body size it is ~0.03 g/kg/day, which is under 5 g even for a 100 kg person, so a flat 5 g/day covers almost everyone. Taking more does not raise muscle creatine further; the excess is excreted.

Q02

Do I need to load creatine?

No, loading is optional. Loading (20 g/day split into 4 doses for 5-7 days, then 3-5 g/day) saturates muscle in ~1 week instead of ~4, but Hultman et al. 1996 showed the final muscle creatine concentration is identical whether you load or take 3 g/day for a month. Load only if you need the effect within a week; otherwise 5 g/day from the start avoids the extra GI upset and faster water-weight gain.

Q03

How much creatine should I take for my bodyweight?

Maintenance scales to ~0.03 g/kg/day (Kreider et al. 2017): ~1.8 g at 60 kg, ~2.4 g at 80 kg, ~3 g at 100 kg. Because every reasonable bodyweight lands under 5 g, a flat 5 g/day is the simplest dose that covers everyone with a margin. Heavier or more muscular people sit at the top of the per-kg range but still need well under 5 g.

Q04

When should I take creatine?

Timing barely matters because saturation depends on total daily intake over weeks, not on one well-timed dose. There is a small signal favoring post-workout intake with carbohydrate and protein via insulin-driven uptake (Antonio & Ciccone 2013), but the effect is minor next to simply taking it daily without missing days. Pick a fixed habit, breakfast or your post-workout shake, and keep it consistent.

Q05

Can I take too much creatine?

Exceeding the saturating dose has no upside: once muscle stores are full the excess is excreted in urine, so 10 g/day saturates no more than 5 g/day while wasting product, and very high acute doses mainly cause GI distress. The ISSN considers 3-5 g/day maintenance and short-term 20 g/day loading safe in healthy adults (Kreider et al. 2017). People with kidney disease should check with a clinician first.

Q06

Do I need to cycle creatine?

No. Creatine does not need cycling or off-weeks; long-term daily use at 3-5 g/day is well tolerated in trials up to 5 years with no adverse kidney or liver effects in healthy people (Kreider et al. 2017). If you stop, stores decline over ~4-6 weeks (Hultman et al. 1996), and you can simply resume 3-5 g/day without re-loading.
