Creatine isn’t just for bodybuilders—and it’s not just a “bulking” supplement. In the world of CrossFit, where explosive power, recovery, and endurance matter just as much as strength, creatine is one of the most researched and effective performance aids out there.
And while it’s a year-round staple for many athletes, summer is an especially smart time to make creatine a part of your routine.
What Is Creatine, and What Does It Do?
Creatine is a naturally occurring compound found in muscle cells. It helps produce ATP (adenosine triphosphate), the energy currency your muscles use during high-intensity, short-duration activities like Olympic lifts, box jumps, and sprint intervals.
Supplementing with creatine increases your muscle stores of phosphocreatine, allowing for faster ATP regeneration. The result? Improved strength, power output, and training volume.
In a CrossFit context, that means heavier lifts, more reps, faster times, and better recovery between sets and sessions.
Why Creatine Matters in the Summer
Summer heat adds a layer of stress to your training. You’re sweating more, possibly training outdoors, and pushing your endurance through the roof. Here’s how creatine supports your body during the hotter months:
- Supports hydration: Creatine draws water into muscle cells, helping keep them hydrated during hot, high-output workouts.
- Enhances recovery: Summer often brings more frequent or longer training sessions. Creatine helps reduce muscle damage and supports faster post-WOD recovery.
- Boosts performance: When you’re pushing hard under the sun, every bit of extra strength and stamina counts.
Contrary to myth, creatine doesn’t dehydrate you. In fact, it may support better hydration at the cellular level—just be sure to drink adequate water, especially in the heat.
How to Take Creatine for Maximum Benefit
- Daily dosage: Take 3 to 5 grams of creatine monohydrate per day. Consistency is more important than timing.
- Loading phase? Optional. Some choose to take 20 grams per day (split into 4 servings) for 5-7 days to saturate muscles faster, but it’s not necessary for effectiveness.
- With or without food? Creatine is best absorbed when taken with a meal or post-workout shake that includes carbohydrates and protein.
There’s no need to cycle off creatine—it’s safe for long-term daily use in healthy individuals.
