"Load 20 grams a day for a week" is some of the most repeated creatine advice out there. It works — but it's a shortcut, not a requirement. Here's how to decide whether it's worth it for you.
Written by Vita Globe Editorial Team | Reviewed against ISSN position stands and peer-reviewed research
Do you need to load creatine?
No. Loading — about 20 g a day (0.3 g/kg) split into four doses for 5–7 days — fills your muscles with creatine in about a week[1]. But taking about 3 g a day with no loading reaches the same muscle creatine level in about four weeks[2]. Loading is useful if you want results quickly; skipping it means fewer doses, less chance of stomach upset and a smaller early change on the scale[3].
Caveat: Either way, you need to keep taking 3–5 g a day afterward. Loading without consistent daily use won't keep your muscles saturated.

What is a creatine loading phase?
Creatine works once your muscle stores are full, or "saturated." A loading phase is a short period of high intake designed to get there fast. The ISSN describes the standard protocol as about 0.3 g of creatine monohydrate per kilogram of body weight per day — roughly 20 g for many adults — split into four doses for 5–7 days, followed by a maintenance dose of 3–5 g per day[1].
Loading vs. no loading: what the research shows
The key study here is from 1996. Researchers compared two approaches: a rapid load of 20 g/day for 6 days, and a low dose of about 3 g/day for 28 days. Both reached a similar final muscle creatine level — the low-dose group just took about four weeks instead of one[2]. The same study found that after loading, about 2 g/day was enough to keep stores elevated[2].
The ISSN's review of common creatine questions reaches the same practical conclusion: loading isn't necessary, but it speeds up saturation, which may matter if you want benefits sooner[3].
| With loading | Without loading | |
|---|---|---|
| Daily amount | ~20 g for 5–7 days, then 3–5 g | 3–5 g from day one |
| Time to full muscle stores | ~1 week | ~3–4 weeks |
| Doses per day | 4 during loading | 1 |
| Early water weight | More noticeable | Smaller, gradual |
| Stomach upset risk | Higher | Lower |
Pros and cons of loading
Pros:
- Benefits start sooner — useful before a competition, a new training block or a test.
- It's well studied and safe for healthy adults at the recommended amounts[1].
Cons:
- Four doses a day is harder to stick to.
- Big doses are more likely to cause stomach upset or diarrhea[3].
- Faster, more noticeable water-weight gain in the first week[1].
- You use through a container much faster.
The honest summary
- Loading is a speed boost, not a requirement.
- Both approaches end up in the same place.
- Most people can simply start at 3–5 g a day and be patient.
Who should load, and who should skip it?
Loading may make sense if: you have an event or training block coming up within the next few weeks and want the benefit quickly.
Skip it if: you have a sensitive stomach, you're in a weight-class sport or watching the scale, you want the simplest possible routine, or you're taking creatine for general health and healthy aging.
How to do a creatine loading phase
- Days 1–7: about 0.3 g/kg/day (roughly 20 g for a 150-lb adult), split into four doses of about 5 g spread through the day[1].
- Take doses with meals to help with stomach comfort.
- Day 8 onward: drop to 3–5 g per day and keep it consistent[1].
With gummies, loading means a lot of gummies — about 16 per day with a 5 g/4-gummy product. That's why most gummy users skip loading and just take one daily serving. Not sure about your daily amount? See How Much Creatine Should You Take a Day?
Our option
Vita Globe Sugar-Free Creatine Gummies
Built for the no-loading approach: one 4-gummy serving gives you 5 g of creatine monohydrate, the top of the daily maintenance range. Sugar-free, third-party tested, in four flavors.
Frequently asked questions
What happens if you don't load creatine?
It just takes longer — about three to four weeks at 3–5 g/day — to reach full muscle stores. The end result is the same[2].
Is loading creatine safe?
For healthy adults, the ISSN considers short-term loading at recommended amounts safe[1]. People with kidney issues should talk to a doctor before taking creatine at any dose.
Do I need to load again if I stop creatine?
Muscle stores return to baseline over several weeks after stopping. When you restart, you can load again or just resume your daily dose.
Can I take 10 g a day instead of loading?
A middle-ground dose will saturate stores faster than 3–5 g, but splitting it into two doses may be easier on your stomach[3]. There's no need to exceed 5 g a day long-term for most people[1].
