BUILT FOR WOMEN · LESSON 1 OF 4

You’re running on a tank that’s 60–80% full.

Hi Klop,

For thirty years creatine sat on the guys’ shelf. Big tubs, big men on the label. The message was clear: not for you.

Here’s the deal. That message had it backwards.

What creatine actually is

It’s the fastest energy your muscles have. It recharges the fuel a muscle burns in the first few seconds of hard work — standing up from a low chair, carrying groceries up the stairs, catching yourself when you trip. About 95% of it lives in your skeletal muscle. The rest is in your brain and heart.

Why you’re probably low

Your body breaks down 1–2% of its creatine every single day, so you need 1–3 grams a day just to break even. Your body makes about half. Food has to cover the rest — and it mostly comes from red meat and fish. On a normal diet, your muscle stores sit only 60–80% full.

Why women are lower still

A research review on creatine across a woman’s lifespan found women carry 70–80% lower creatine stores than men and eat less of it, too. The people who were told creatine wasn’t for them started with the least.

Why it matters after 40

Adults lose 3–8% of their muscle every decade after 30, and the loss speeds up after 60. That muscle isn’t just for looks. It clears about 80% of the sugar from your blood after a meal. It’s what moves you. And it pulls on your bones every time you move.

Your takeaways

Your muscles hold 95% of your body’s creatine — it’s muscle fuel, not a guy thing.
A normal diet leaves your tank 60–80% full. Supplementing tops it up by 20–40%.
Women start with 70–80% less than men.
Muscle is your blood-sugar sponge: it handles about 80% of post-meal sugar.

But before you buy a tub, here’s the part nobody prints on the label: creatine on its own doesn’t do much.

I’ll show you the two-year study that proved it.

It's your turn now.
