Best Creatine Supplements of 2025

Why Creatine Actually Works (Unlike Most Supplements)

Let's be honest: most supplements are overhyped garbage. Creatine is different.

The International Society of Sports Nutrition calls it "the most effective ergogenic nutritional supplement currently available to athletes." That's not marketing—that's based on over 500 studies spanning 25+ years.

Here's what creatine does in plain English: Your muscles run on a molecule called ATP (adenosine triphosphate). When you're lifting heavy or sprinting, ATP gets depleted fast. Creatine acts as a backup battery, helping your muscles recharge ATP quickly so you can squeeze out a few more reps or sprint harder.

The result? More strength, more muscle growth, better performance. And unlike sketchy "muscle pills," creatine is naturally found in meat and fish—your body already makes about 1 gram per day.

The Research is Crystal Clear

Here's what happens when you take creatine while training:

• Strength gains: Studies show 5-15% increases in maximal strength and work output
• Muscle mass: Expect to gain 2-4 pounds of lean mass in the first month (yes, some is water, but muscle cells need water to grow)
• Sprint and power: Better performance in activities under 30 seconds (weightlifting, sprints, jumping)
• Injury reduction: Athletes taking creatine actually had lower injury rates in studies—probably because stronger muscles protect joints

Doesn't work for endurance? That's mostly true. Marathon runners won't see much benefit. But if you're lifting, doing HIIT, playing sports with bursts of power, or trying to build muscle—creatine works.

Monohydrate vs. HCL: The Truth About "Fancy" Forms

Walk into any supplement store and you'll see a dozen types of creatine. Here's the real difference:

Creatine Monohydrate = The Gold Standard

This is the form used in 95% of research. It's:

• 90% pure creatine by weight (the other 10% is water)
