A plain guide to creatine for beginners: what it does, how much monohydrate to take, whether to load, when to take it, and which common myths do not hold up.
Creatine works, and it is the best-studied supplement for people who train. Take 3 to 5 g of creatine monohydrate every day, at whatever time you will remember. Loading (about 20 g a day split into 4 doses for 5 to 7 days) fills your muscles faster but is optional. Expect 1 to 3 lb of water weight early on. In healthy people it does not harm the kidneys or cause dehydration, but check with your doctor first if you have kidney disease or any medical condition.
Creatine is the one supplement most coaches will tell a beginner is worth buying. It is cheap, it has been studied for decades, and it does something real: it lets you squeeze a little more work out of hard sets, which over months adds up to a little more strength and muscle.
It is also surrounded by myths about kidneys, hair, and cramps, and by confusing advice about loading and timing. This guide covers what creatine does, how much to take, when to take it, and what it will and will not do for you.
Your muscles store a small amount of creatine as phosphocreatine. During short, hard efforts, like a set of 8 squats, phosphocreatine helps regenerate the energy your muscles burn fastest. Those stores run low within seconds of hard work.
Supplementing raises how much creatine your muscles hold. With fuller stores, you can often get an extra rep or two on a hard set, or keep reps up better across several sets. That is the whole mechanism. Creatine does not build muscle on its own. It lets you do slightly more training, and the extra training does the building.
The evidence for that is solid. The International Society of Sports Nutrition's 2017 position stand, led by Kreider, concluded that creatine monohydrate is effective when combined with training and safe in healthy people. A 2022 meta-analysis by Delpino and colleagues found that creatine plus resistance training increased lean mass more than resistance training alone.
Take 3 to 5 g of creatine monohydrate per day. That is the maintenance dose recommended in the ISSN position stand, and it is enough for nearly everyone. A level teaspoon of most powders is close to 5 g, but check the label of the one you buy.
| Your situation | Daily dose | Notes |
|---|---|---|
| Most beginners | 3 to 5 g | Any time of day, every day |
| Larger, heavily muscled lifters | 5 g | The top of the range is plenty |
| Want results faster (optional) | 20 g for 5 to 7 days, then 3 to 5 g | Split the 20 g into four 5 g doses |
More than 5 g a day does not help once your muscles are full. The extra is simply excreted.
Buy plain creatine monohydrate. It is the most studied form by a wide margin, and it is usually the cheapest. Other forms cost more without better evidence. Micronized monohydrate just mixes more easily.
No. Loading is optional. A 2021 review by Antonio and colleagues on common creatine misconceptions made this point directly: loading is not required.
Here is the difference:
After a month, both approaches end up in the same place. Loading only gets you there sooner. Some people get an upset stomach from 20 g a day, which is one reason many beginners skip it. If you do load, splitting the dose across meals helps.
Whenever you will remember to take it every day. Creatine works by keeping your muscle stores topped up over weeks, not by giving you a boost in the hour after you take it. Taking it before versus after training makes little practical difference.
What matters is consistency:
Probably a little, at first. Creatine pulls water into your muscle cells, so many people gain 1 to 3 lb in the first few weeks, more quickly if they load. This is water stored inside muscle, not fat, and it is not the puffy, bloated look people sometimes worry about.
If you are cutting, expect a small early jump on the scale and judge progress over weeks. If you are bulking, do not count that jump as muscle gain.
Creatine has a reputation problem that the research does not support. The Antonio 2021 review went through the most common claims one at a time.
In healthy people, no. Studies have not found kidney harm at normal doses. One source of confusion is that creatine can raise creatinine on a blood test, which is a marker doctors use to estimate kidney function. A higher number caused by creatine does not mean your kidneys are struggling, but tell your doctor you take it so they can read your results correctly.
This claim traces back to one small study that found a change in a hormone linked to hair loss. It did not measure hair loss, and the finding has not been established by later research. There is no good evidence that creatine makes you go bald. Our guide on whether creatine causes hair loss covers that study and a 2025 trial that measured hair directly.
No. The research does not show that creatine causes dehydration or muscle cramps. Drink normally and pay attention to thirst, as you would anyway when training.
Talk to your doctor before taking creatine if you:
This is not medical advice. If anything about your health makes you unsure, ask your doctor before you start.
No, and this is the most important point in the whole guide. Creatine amplifies training. It does not replace it. The extra rep it gives you only matters if your program is built to use it.
A typical result looks small session to session. Say you are on a goblet squat in a range of 8 to 12 reps:
| Session | Without creatine (typical) | With creatine (typical) |
|---|---|---|
| 1 | 50 lb × 10, 9, 8 | 50 lb × 10, 10, 9 |
| 2 | 50 lb × 10, 10, 9 | 50 lb × 11, 10, 10 |
| 3 | 50 lb × 11, 10, 10 | 50 lb × 12, 11, 11 |
The numbers here are illustrative, not from a study. The point is the pattern: a rep here and there, compounding over months. If you train inconsistently, do the same weight for the same reps every week, or stop sets far from failure, creatine has nothing to amplify.
The basics still decide most of your progress:
Alexandros is an iPhone app that works like a personal weightlifting coach you talk to in a chat. It does not track supplements, so creatine is on you. What it handles is the part creatine depends on: making sure your training keeps progressing so the extra reps have somewhere to go.
You log a session by describing it in plain English, like "goblet squat 3 sets with the 50, 12, 11, 11, last set was hard," and it turns that into structured sets with an effort rating. Recommendations use double progression through a rep range set by your goal and the type of lift, adding a rep when you are inside the range and adding weight when you reach the top with at least a rep in reserve. Ask "How has my squat progressed?" and you get a chart of top weight, estimated one-rep max, and volume from your actual log. If you start creatine, that chart is the honest way to see whether anything changed over the next few months.
No. There is no need to take breaks from creatine. Taking 3 to 5 g a day continuously is the standard approach in the research. If you stop, your muscle stores drift back to normal over several weeks, and you lose the small water-weight gain with them.
Yes. The same dose of 3 to 5 g a day applies, and the same benefits for training apply. The early water-weight gain is usually small and is stored in muscle, not as visible bloating.
They may benefit more than most. Because meat and fish are the main dietary sources, vegetarians and vegans often start with lower muscle stores, so supplementing tends to raise them more.
Yes, but keep expectations in proportion. As a beginner, you will make fast progress anyway from learning the lifts and training consistently. Creatine adds a little on top. Get the training right first.
