Creatine: The Most Researched Supplement You’re Probably Not Taking (But Should Be)

At CrossFit Viroqua, we talk a lot about long-term health, strength, and performance, not shortcuts.

And when people ask me about supplements, I usually keep it simple:
Most people don’t need much.

But there is one supplement that consistently stands above the rest in terms of research, safety, effectiveness, and long-term benefit:

Creatine.

Let’s break it down.

What Is Creatine?

Creatine is a naturally occurring compound stored primarily in your muscles. Your body makes some of it in the liver and kidneys, and you also get it from food, mainly red meat.

Here’s the problem:

Most people don’t eat enough red meat to fully saturate their muscle creatine stores.
And if you are:

You are very likely under-consuming creatine.

Why People Who Don’t Eat Red Meat Need It Even More

Red meat is the richest dietary source of creatine.

If you don’t eat it regularly, your baseline muscle creatine levels are lower. That means:

Research consistently shows that vegetarians often experience even greater performance improvements when supplementing with creatine because they start from lower baseline levels.

If you’re training hard at CrossFit Viroqua but avoiding red meat, creatine is not optional, it’s strategic.

What Energy System Does Creatine Help?

Creatine fuels the ATP-PC (phosphagen) energy system.

This is the system responsible for:

Here’s what happens:

Your body uses ATP (adenosine triphosphate) as immediate energy.
ATP gets depleted rapidly during intense effort.

Creatine helps regenerate ATP faster.

That means:

And in CrossFit, that matters.

Benefits of Creatine (Beyond the Gym)

Creatine isn’t just about bigger lifts.

Research supports benefits in:

1. Increased Strength & Muscle Mass

More training volume = more adaptation over time.

2. Improved Recovery Between Sets

Better repeated efforts.

3. Brain Health

Creatine plays a role in cellular energy production in the brain. Studies suggest benefits in cognitive performance, especially under stress or sleep deprivation.

4. Healthy Aging

As we age, we lose muscle mass (sarcopenia). Creatine supplementation combined with resistance training helps preserve lean mass and strength.

For our Legends athletes (50+), this is huge.

How Much Creatine Should You Take?

The evidence-based dose:

3–5 grams per day

That’s it.

You do NOT need:

Some people choose to “load” with 20g/day for 5–7 days, but it’s not required. Taking 3–5g daily will saturate your muscles over a few weeks.

Consistency > loading.

Creatine Monohydrate vs Other Forms

Here’s the simple truth:

Creatine Monohydrate wins.

It is:

Other versions you’ll see:

None consistently outperform basic creatine monohydrate.

Many just cost more.

Look for:

That’s it.

Does Creatine Cause Weight Gain?

Yes, but not in the way people fear.

Creatine increases intramuscular water retention, meaning your muscles hold slightly more water inside the muscle cell.

This:

It is NOT fat gain.

Most people see a 1–3 pound increase initially. That is normal.

Is Creatine Safe?

Creatine is one of the most researched supplements in sports nutrition.

Decades of data show:

If you have pre-existing kidney disease, consult your physician first. Otherwise, for healthy individuals, it’s extremely safe.

Should You Take Creatine?

If you:

The answer is likely yes.

Creatine isn’t a magic pill.

But it is one of the few supplements that actually does what it promises.
