Legion Creatine Review (2026): Our Thoughts

Legion creatine is a favorite among our older adult supplement testers. We chose the brand’s micronized creatine as our pick for best creatine monohydrate for men. And Legion's gummies earned best creatine gummies on our list of best creatine for women.

As muscle mass changes, so does creatine storage in the muscles.¹ Creatine supplements can help build muscle. They also may reduce age-related muscle loss. This is more likely when you add resistance training. In our September 2026 Supplement Survey, we asked older adults why they take creatine. "Reducing age-related muscle loss” and “staying strong enough for everyday activities” were their top two reasons.²

In this Legion creatine review, we share how the brand's powder and gummies performed in our tests. We evaluated both for taste, ingredients, price, and mixability.

Why we recommend Legion creatine

We recommend Legion because it provides ingredient information and third-party testing results. The Food and Drug Administration (FDA) doesn't approve supplements before they go to market. So we look for brands that independently test ingredients and quality.

“Testing supplements ensures their potency and purity in the creation of the product before ever recommending anything,” said Katie Whitson, RDN, LDN, MS, a registered dietitian in Thornton, Colorado.

Certified personal trainer Mike Matthews founded Legion in 2014. Matthews wrote, “I know what it’s like wandering the aisles of GNC, wondering what’s good and what’s not." He created Legion to make high-quality supplements "based on sound science." His other goal is "to sell them honestly and at a fair price." Legion launched a scientific advisory board in 2026 to help guide its supplement research. Our testers liked that Legion goes out of its way to provide clarity to its consumers. It even posts the full Labdoor reports on its website.

Legion’s creatine gummies and micronized creatine powder earned high testing scores. Our testers praised the taste, packaging, serving size, and value.

How we tested Legion creatine

Here’s what our panel of testers looked at to judge if Legion creatine was worth taking and recommending.

Legion Creatine Gummies: Candylike creatine

Testers gave Legion’s gummies 5/5 for taste. They said the flavorful gummies made it easier to take creatine every day. They also found the container convenient to bring on the go. Each Legion serving has 5,000 milligrams (5 grams) of creatine.

Our experience with Legion Creatine Gummies

Legion’s gummies made a strong first impression, earning a 5/5 with our testers. “It smells good, it looks legit,” one tester said. These gummies also earned 5/5 for simple instructions because all you need to do is take four gummies per day. You just might need to squint to read the label. “It’s not the smallest print I’ve seen,” one tester reported, “but I did need my glasses.” 

The creatine gummies tasted pleasant enough to earn another 5/5 for flavor. “It’s easy to chew, and it tastes good,” one tester said. “There is a thin sugary coating that’s sweet but not too sweet.” Testers added that the sour strawberry flavor “tastes like bubblegum or kids’ toothpaste.” The gummies are bubblegum pink, to match. Legion achieves this color through beetroot powder. 

Testers reported no side effects—not even an aftertaste. Legion Creatine Gummies contain sweeteners such as maltitol syrup, a sugar alcohol. Depending on which flavor you choose, the amount of added sugar varies. The lemon drop flavor has 10 g of added sugar per serving.

“This is easy and tasty,” one tester said. “I could take this on the go, which makes it easy to add to my routine.” The only thing our testers didn’t love about Legion Creatine Gummies was the price. One serving of four gummies costs around $1.46. That's more per serving than many creatine powders we tested. But it's less than many other creatine gummies.

Legion Micronized Creatine Monohydrate: Mixable powder with fun flavors

Legion’s micronized creatine comes in a sleek black tub. Micronized means the creatine has been processed into smaller particles for mixability. Like Legion's gummies, this creatine powder delivers 5,000 mg of creatine per serving. Testers were impressed not only with the packaging, but with the lack of artificial dyes.

• Form: Powder
• Added sugar: 0 g

Pros and cons

Pros

• Affordable cost per serving
• No added sugar
• Transparent allergen information
• Testers enjoyed the fruit punch flavor

Cons

• Powder doesn’t mix in completely

• Not eligible for purchase with health savings account (HSA) funds

Our experience with Legion Micronized Creatine Monohydrate

Our testers gave Legion's creatine powder the same high flavor ratings as the gummies. But they liked the powder's price a lot more. Testers rated both taste and price 5/5. A one-scoop serving of Legion creatine powder costs about 50 cents. It's one of the most affordable creatine supplements we tested.

The micronized creatine monohydrate earned a 4.5/5 for first impressions. “The pink color is really pretty in the water,” said one tester. "The package is really beautiful in general.” Our testers said the instructions were clear and user-friendly. The print was large enough to read with glasses.

Testers rated the fruit punch flavor 5/5. “I like the taste a lot. It’s not overly in your face,” one tester said. “It tastes like a very diluted fruit punch.” The light pink color comes from fruit and vegetable juices, not artificial dyes.

Legion’s Micronized Creatine Monohydrate powder earned a 4.5/5 for mixing because it didn’t mix entirely. “It doesn’t dissolve perfectly,” one tester said. “You can see the powder sort of falling down and then settling at the bottom of the bottle.” Despite the powder settling at the bottom, testers said it didn't taste gritty or chalky.

What are the benefits of Legion creatine?

Creatine has been studied extensively for its role in retaining muscle mass. But some people also take creatine to boost energy and brain function. “The brain uses creatine as an energy source, and the thought is that creatine may support cognitive function and memory and processing speed,” said Amy Goldsmith, RD, a Maryland-based registered dietitian and owner of Kindred Nutrition and Kinetics. Early research suggests creatine may help with attention and memory. But more studies are needed.³

Legion primarily markets its creatine products for muscle strength, growth, and recovery. But creatine alone won’t help you build muscle. To reap the full benefits, resistance training is key while taking creatine.⁴ 

Creatine supplements like Legion’s may support bone health in women. But this research is still ongoing. Menopause causes a decline in estrogen, which can lead to a loss of bone density.⁵ Strength training can support muscle and bone health. Researchers continue to study whether adding creatine can further improve bone density.

What are the potential side effects of Legion creatine?

Studies suggest creatine is generally well tolerated by healthy adults when taken as directed.⁶ Most creatine studies are based on healthy adults who stay within the recommended daily serving size of 3–5 g.⁷ Still, check with your doctor before supplementing with creatine. Your doctor can help make sure you're not taking any medications that might interact negatively with creatine. 

Registered dietitians we spoke with warn mostly of kidney complications. “People with kidney disease or taking medications that affect the kidney should speak with their physician before taking creatine supplements,” said Reema Kanda, RD at Hoag Orthopedic Institute in Irvine, California. “Long-term studies have suggested creatine is safe for short-term use in adults with mild kidney challenges.” 

Evidence on creatine safety in people with existing kidney conditions is limited. Talk with your doctor before taking creatine if you have kidney disease or take medications that affect kidney function. One published case report described kidney failure in a person taking creatine.⁸ A case report alone cannot establish that creatine caused the kidney failure.

Some Legion flavors have added sugar, while others have steviol as an added sweetener. Stevia can cause minor GI distress in some people. One of our older adult testers also reported minor nausea when taking creatine on an empty stomach. Follow the serving instructions on the product label and ask your doctor whether creatine is appropriate for you.

How to take Legion creatine

Legion Creatine Gummies include four gummies per serving. For Legion Micronized Creatine Monohydrate, one scoop of powder is one serving. Empty the scoop into 10–12 ounces of water and stir until mixed. 

While many people take creatine before a workout, you don’t have to. Creatine has a cumulative effect. The experts we spoke to said consistency matters most. Taking creatine at the same time each day may help you add it to your routine.

Who should consider Legion creatine?

Legion creatine is transparent about its third-party testing. The brand is honest about any artificial dyes used in its products (none), added sugars (some), and other ingredients (usually fruit juice). Allergen information is well-labeled. 

Our testers found the tub of micronized powder simple to open and the gummy container portable. The only issue our testers had with Legion’s packaging was the print. On the gummy bottle especially, they said it was small and a tad difficult to read. 

Legion’s gummy prices are on the higher end for a creatine supplement. But its creatine powder is one of the more affordable supplements we tested. Legion also offers a discount if you sign up for a subscription.

You should consider Legion creatine if you:

• Prefer a tasty flavored creatine
• Want 5,000 mg of creatine per serving
• Are seeking a creatine free of artificial dyes

You may consider other options if you:

• Want a creatine powder that comes in individual serving packets
• Want a powder that mixes perfectly
• Are looking for a more affordable creatine gummy

Frequently asked questions

Is Legion good creatine?

Both Legion Micronized Creatine Monohydrate and Legion Creatine Gummies earned high scores from our testers. The 5,000 mg serving of creatine monohydrate in both products falls within the commonly studied daily range of 3,000–5,000 mg. Legion creatine is a favorite among our testers for flavor, packaging, ingredients, and cost. 

Which is the most trusted creatine brand?

When comparing creatine brands, look for transparent ingredient labels and independent testing from recognized organizations like USP, Informed Choice, or NSF. Brands without testing approval from those organizations can still be trusted. But look for brands with transparent ingredient lists and third-party testing results that are easy to find.

Is Legion creatine safe?

Legion creatine products have undergone third-party testing through Labdoor. Creatine is generally considered safe for healthy adults when taken as directed. But it may not be appropriate for everyone. Talk with your doctor before starting creatine, especially if you have kidney disease or take prescription medications.

Is it safe to take creatine with citalopram?

Research on taking creatine with selective serotonin reuptake inhibitors (SSRIs), including citalopram, is limited. The available studies do not establish that this combination is safe for everyone.⁹ Talk with your doctor or pharmacist before combining creatine with citalopram.
