Creatine for Cyclists: My Experience After 3 Years of Using It

Before I get into this, full disclosure: I’m not a doctor or nutritionist. I’m just a cyclist who got curious about creatine, did some research, tried it, and formed opinions. Take this as one person’s experience, not medical advice.

Okay, with that out of the way – creatine is interesting stuff. And weirdly controversial for how much science is actually behind it.

What Is This Stuff Anyway?

Creatine is a compound your body already makes naturally. It’s stored mostly in your muscles and helps produce ATP – basically your cells’ energy currency. You also get small amounts from eating meat and fish.

The supplement form is usually creatine monohydrate, which is just a concentrated version. It’s been around forever, studied extensively, and is one of the few supplements that actually does what it claims to do.

Why I Started Taking It

Honestly? Curiosity and a steep learning curve on strength training. About three years ago I added weightlifting to my routine to complement cycling. A trainer suggested creatine and I figured why not try it.

I was skeptical at first. Most supplements are garbage – expensive placebos at best. But creatine has decades of research behind it, and the consensus is pretty clear: it works for strength and power output.

What I’ve Actually Noticed

In the gym: I can push harder on my last few reps. Recovery between sets feels slightly faster. Is it dramatic? No. But it’s noticeable, especially during heavy compound lifts.

On the bike: Here’s where it gets murkier. Creatine is mainly for short, high-intensity efforts – think sprints and hard attacks, not steady endurance work. I noticed it helps with the last punch at the end of a group ride or the kick to the line in a race. For just riding along at moderate intensity? Probably doesn’t do much.

Weight: I gained about 3-4 pounds of water weight when I started. This is normal – creatine pulls water into your muscles. Some cyclists don’t like this because extra weight affects climbing. I haven’t found it to be a problem, but I’m not a skinny climber type anyway.

How I Take It

I skipped the “loading phase” that some people recommend (20 grams a day for a week). It’s supposed to saturate your muscles faster, but I couldn’t deal with the stomach issues. Just 5 grams a day from the start worked fine for me – took a few weeks longer to fully kick in but zero digestive problems.

Timing doesn’t seem to matter much based on research. I just mix it into my post-workout shake so I don’t have to think about it.

I use plain creatine monohydrate – the cheap stuff. All those fancy forms like “creatine HCL” or “buffered creatine” don’t appear to work any better according to studies. Just companies trying to justify higher prices as far as I can tell.

The Side Effects (For Me)

Water retention: Like I said, gained a few pounds initially. It levels off after a week or two.

Thirst: I drink more water now. This could be the creatine or it could just be that I’m more conscious of hydration. Either way, stay hydrated.

Stomach issues: Only when I tried the loading phase. At 5g/day I’ve had zero problems.

Kidney concerns: This is the big worry people have. The research doesn’t support it for healthy people – there’s like 30 years of studies showing creatine is safe for normal kidneys. But if you have existing kidney issues, obviously talk to a doctor first.

Busting Some Myths

“Creatine is a steroid” – Nope. Completely different thing. Steroids are hormones. Creatine is an amino acid compound. Not even in the same category.

“It causes dehydration” – Actually no. Studies don’t support this. But you should probably drink more water anyway since creatine draws water into muscles.

“You’ll lose all your gains when you stop” – Partially true. You’ll lose the water weight, and your short-term power output might dip slightly. The actual muscle you built stays. I’ve cycled off a few times and this matches my experience.

“Only meatheads use creatine” – Kind of dumb. It helps with any activity requiring high-intensity efforts. Sprinting, jumping, attacking in races, lifting heavy things. Plenty of endurance athletes use it for those explosive moments.

Is It Worth It for Cyclists?

Depends on what kind of cyclist you are:

If you do strength training: Yeah, probably worth it. The evidence for improved strength output is solid.

If you’re a sprinter or crit racer: Could help with those high-power efforts.

If you’re purely a long-distance endurance rider: Less clear benefit. Steady-state cardio isn’t really what creatine is for.

If weight matters a lot (climbing, long events): The 3-5 pounds of water weight might be a concern. Personal call on whether the strength benefits outweigh it.

What I Actually Use

I buy the big tubs of creatine monohydrate from whatever brand is cheapest at the time. Optimum Nutrition, NOW Foods, MyProtein – they’re all fine. It’s a commodity product; the cheap stuff is the same as the expensive stuff.

At 5 grams per day, a 500g tub lasts like 3 months and costs maybe 15-20 bucks. Dirt cheap for something that actually works.

The Bottom Line

After three years, I’m still taking creatine and plan to continue. The strength benefits in the gym are real. The potential benefits for high-intensity cycling efforts seem real too, though harder to isolate. The downsides are minimal.

Is it necessary? No. Can you be a great cyclist without it? Absolutely. But it’s cheap, safe, backed by science, and gives a small edge in certain areas. That’s more than you can say for most supplements out there.

Just don’t expect miracles. It’s a marginal gain, not a magic pill. But in a sport where we obsess over marginal gains, it’s one of the few legal supplements that actually delivers.
