Our top choice for best overall creatine supplement comes from Thorne. To round out the rest of our best available, we enlisted the expertise of a registered dietitian.
Creatine is one of the most popular sports supplement on the market, thanks to its impressive benefits for performance and strength.
It’s also widely available, with one review estimating that creatine supplements pull in around $400 million in sales annually around the globe (1).
However, not all creatine supplements are created equal, and with so many options available, finding a high quality supplement can be challenging.
Here’s everything you need to know about 10 of the best creatine supplements.

Creatine is a compound produced by your body and found naturally in a variety of foods, including milk, meat, and seafood (1).
It’s also a widely used supplement. Creatine monohydrate, which consists of a creatine molecule paired with a water molecule, is the most common and best-researched type of creatine supplement (1, 2).
Some supplements combine creatine with other compounds intended to increase absorption or boost performance, such as magnesium, citric acid, malic acid, or hydrochloride.
Potential benefits
Creatine can increase levels of phosphocreatine, a compound your body uses to form adenosine triphosphate (ATP). Your body breaks down ATP for energy (3).
For this reason, people typically use creatine supplements to enhance performance in high intensity exercise.
Creatine supplements have been shown to increase strength, promote muscle growth, and reduce muscle damage (1, 4, 5).
Some research has found that creatine could also help reduce mental fatigue, protect brain function, and slow signs of aging (3, 6).
Though more studies are needed, some research in humans and animals also suggests that creatine may be beneficial for blood sugar regulation (7).
Uses
Creatine is a widely available supplement that is typically found in capsule or powder form.
It is also sometimes added to sports supplements, such as pre-workout drinks, alongside other ergogenic aids, including caffeine and amino acids.
Experts generally recommend taking creatine supplements daily, either before or after working out, and using a higher dose for the first 5–7 days followed by a maintenance dose thereafter (8).
One of the most commonly reported side effects of creatine is a short-term increase in fluid retention, which may be the result of creatine’s osmotic properties (3, 22).
Creatine supplementation has also been consistently associated with weight gain, especially during the loading phase. However, this may due to increases in muscle mass and water retention rather than an increase in body fat (22, 23, 24).
Some other anecdotal side effects often reported with creatine supplementation are (3, 22):
digestive issues
dehydration
muscle cramps
kidney or liver problems
However, according to the International Society of Sports Nutrition (ISSN), there is no evidence that creatine causes any of these side effects (3).
Additionally, the ISSN notes that both short- and long-term supplementation with creatine are considered safe and effective for improving exercise performance and preventing or reducing the severity of injuries (3).
When selecting a creatine supplement, be sure to consider the ingredient list and dose provided. It’s also a good idea to select a product that has been third-party tested.
Ingredients
Check the ingredient label carefully and look for products free of artificial flavors, sweeteners, colors, and fillers whenever possible.
However, note that some supplements may contain added carbs or protein, which can help increase the retention of creatine (3).
Dose
You should also pay close attention to the dosage of creatine supplements.
Experts generally recommend starting with a loading phase of 20–25 g per day for 5–7 days to increase muscle stores of creatine and then using a maintenance dose of 3–5 g per day thereafter (8).
Third-party testing
If possible, you should also choose supplements that have undergone third-party testing and are certified by an organization such as NSF or Informed Choice to ensure safety and quality.
Some companies may also provide a COA upon request, which offers detailed information about the purity and potency of products.
If you’re a competitive athlete, choose a product that is certified safe for sport. Organizations such as NSF and Informed Sport provide certifications that ensure products are free of substances that are banned by most professional sporting organizations.

Research shows that creatine is safe and effective for healthy adults, even if you take it every day.
According to one review, creatine has not been associated with significant negative side effects, even when taken in high doses of up to 30 g per day for 5 years (3).
What happens if you stop taking creatine?
Once you stop taking creatine, your body’s levels of stored creatine may decline, which could lead to changes in energy levels, strength, and body composition.
Should beginners take creatine?
Creatine is safe and effective, even for beginners. Experts generally recommend starting with a loading phase of 20–25 g per day for 5–7 days and then using a maintenance dose of 3–5 g per day thereafter (8).
Does creatine make you gain weight?
Most creatine supplements are calorie-free or very low in calories and are therefore unlikely to contribute enough calories to cause weight gain.
However, one of the most common side effects of creatine is water retention in the first few days of supplementation. While you might see your weight increase initially, research doesn’t suggest that creatine causes long-term water retention or subsequent weight gain (22).
Creatine has also been linked to increases in muscle mass, which could lead to an increase in weight.
Who shouldn’t take creatine?
Because creatine in the blood is an important measure for liver and kidney function, people who have liver or kidney conditions or are taking medications for liver and kidney function should talk with a trusted healthcare professional before taking creatine supplements (25).
Additionally, people who are pregnant, breastfeeding, or taking any prescription medications, especially medications that affect blood sugar levels, should consult a healthcare professional before adding creatine to their wellness routine.
