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 are 10 of the best creatine supplements.

What is creatine?

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).

A comparison of the best creatine supplements

Here’s a quick look at how our top picks compare:

How to choose

When selecting a creatine supplement, be sure to 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).

You should also pay close attention to the dosage of creatine supplements.

Experts generally recommend starting with a loading phase of 20–25 grams per day for 5–7 days to increase muscle stores of creatine and then using a maintenance dose of 3–5 grams per day thereafter (8).

If possible, you should also choose supplements that have undergone third-party testing and are certified by an organization like 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.

Potential risks and side effects

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, 20).

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 (20, 21, 22).

Some other anecdotal side effects often reported with creatine supplementation are (3, 20):

• 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).

Frequently asked questions

Is it OK to take creatine every day?

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 grams 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 grams per day for 5–7 days and then using a maintenance dose of 3–5 grams 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 (20).

Creatine has also been linked to increases in muscle mass, which could lead to an increase in weight.

The bottom line

Creatine supplements are available in a variety of forms, flavors, and dosages.

When searching for the right product for you, be sure to check the ingredient label and dosage carefully.

Ideally, you should purchase products that have undergone third-party testing or have a COA available upon request.
