Three to four weeks at 5 g per day. That is how long muscle creatine stores take to fill from a standard daily dose, and it is the number to plan around.

A loading protocol compresses it to 5 to 7 days, at the cost of taking four servings a day. Neither route changes the end point, only how fast you reach it.

This page is not a ranking

Nobody notices anything in week one, and any page telling you otherwise is describing something other than creatine saturation. Here is the actual timeline, including the part where nothing happens.

The short answer

At 5 g per day, expect 3 to 4 weeks to reach full muscle saturation. With a loading protocol, 5 to 7 days. Week one on a standard dose is, by design, uneventful.

The standard route: 3 to 4 weeks

Initially, ingesting smaller amounts of creatine monohydrate (e.g., 3-5 g/day) will increase muscle creatine stores over a 3-4 week period, however, the initial performance effects of this method of supplementation are less supported.

Kreider et al. (2017), Journal of the International Society of Sports Nutrition 14:18

The ISSN position stand notes that the early performance effects of a standard 3 to 5 g daily dose are less well supported, which is a fair warning that the first fortnight is quiet.

The fast route: 5 to 7 days

The most effective way to increase muscle creatine stores is to ingest 5 g of creatine monohydrate (or approximately 0.3 g/kg body weight) four times daily for 5-7 days.

Kreider et al. (2017), Journal of the International Society of Sports Nutrition 14:18

Four servings a day means 20 g daily for 5 to 7 days. With gummies that is 12 gummies a day, which is a real cost in both pouches and willingness. Loading is optional, not required.

The timeline

Period At 5 g per day With a loading phase
Days 1 to 7 Stores rising from a 60 to 80 percent baseline. Nothing to notice Saturation reached at 20 g/day
Week 2 Still filling Maintaining at 5 g/day
Weeks 3 to 4 Saturation reached Maintaining
Ongoing 5 g/day holds stores full Identical. The routes converge
If you stop 4 to 6 weeks back to baseline 4 to 6 weeks, same

Whichever route you take, the destination and the decay are identical. Loading buys about three weeks, once.

Why the scales might move first

Creatine draws water into muscle cells, so early weight change of roughly 0.5 kg to 1.5 kg is common in the first few weeks. That is water, not tissue, and it stabilises. It is a sign the compound is being taken up rather than a result in itself.

The experiment that actually settles the loading question was run decades ago, and a recent review restates it:

For example, in the classic 'loading' vs. daily 'maintenance' dose comparison study by Hultman et al., creatine accumulation in muscle was similar (~ 20% increase) after participants consumed 3 g/day for 28 days or 20 g/day for 6 days.

Antonio et al. (2021), Journal of the International Society of Sports Nutrition

The same 20 percent increase either way. Loading changes how fast you arrive, not where you arrive, and 28 days at a normal dose reaches the same place as 6 days at nearly seven times the dose.

How Supps does it

A pouch of Supps is 90 gummies, which at one serving of three a day is 30 days, and happens to be about the length of the standard saturation window. Each serving is 5 g of creatine monohydrate. Every batch is independently tested by RSSL and Eurofins UK, with measured results at our lab results page, in grams, for every batch.

Creatine increases physical performance in successive bursts of short-term, high intensity exercise. This benefit is obtained with a daily intake of 3 g of creatine. Three Supps gummies provide 5 g.

Frequently asked questions

How long does creatine take to work?

3 to 4 weeks at 5 g per day, which is how long muscle stores take to reach saturation. A loading protocol of roughly 20 g per day reaches the same point in 5 to 7 days.

How long until I see results from creatine?

Plan for 3 to 4 weeks on a standard 5 g daily dose. The research itself notes that early effects from this approach are less well supported, so a quiet first fortnight is expected rather than a sign something is wrong.

Do I need to load creatine?

No. Loading reaches saturation in 5 to 7 days instead of 3 to 4 weeks, and that is the only difference. Both routes end at the same place and both decay over the same 4 to 6 weeks if you stop.

Why do I feel nothing in week one?

Because muscle stores start around 60 to 80 percent full on a normal diet and rise gradually at 5 g per day. Creatine is a stored reserve rather than a stimulant, so there is no acute effect to feel.

Is the early weight gain fat?

No. Roughly 0.5 kg to 1.5 kg in the first few weeks is water drawn into muscle cells, and it stabilises.

How long do the effects last if I keep taking it?

Stores stay full for as long as you take 5 g per day. If you stop, they return toward baseline over 4 to 6 weeks.
