We know what you’re thinking—“Creatine? Isn’t that just for bros and bulking season?” Nope, Creatine for Fertility is where it’s at, my friends.

We fell down a science-rabbit hole (as one does), and guess what we found? Let’s just say creatine might be on of the the unsung hero of the fertility world.

Here at Aphrodite Fertility, we’re not about throwing supplements at you unless they’re vetted, validated, and very much not wasting your money. But creatine? She’s got range. And research.

Let’s break it down.

Creatine 101: What It Actually Does (No Dumbbells Required)

Creatine is a naturally occurring compound made in your liver, kidneys, and pancreas—and also found in foods like red meat and seafood. Most people know it as a muscle and performance enhancer, but what most people don’t know is…

Your ovaries, uterus, brain, and placenta all use creatine to produce energy.

Yes. The organs that fuel conception and pregnancy are some of the most creatine-hungry in your body.

So if you’re TTC (trying to conceive), and especially if you’re plant-based or eating less meat, your creatine levels might be lower than ideal—which could be impacting your fertility without you realizing it.

How Creatine Supports Female Fertility (It’s More Than Just Gains)

According to studies (like this one from the NIH), creatine plays a role in:

• Cellular energy production (aka giving your eggs the oomph they need)
• Ovarian health (improving the energy environment around your follicles)
• Egg quality (especially important for women 30+)
• Endometrial function (a well-fueled uterus = better implantation potential)
• Early embryo development (and that’s the real game-changer)

Creatine During Pregnancy: Why the Science Is Getting Excited

Newer research (like this gem from the Hudson Institute) suggests creatine supplementation during pregnancy may:

• Protect the fetal brain and other vital organs during birth
• Support placental function
• Help buffer against birth-related complications

Which means we might be looking at a future where creatine is a standard prenatal supplement—right up there with folate and iron.

Is Creatine Safe to Take While Trying to Conceive?

Short answer? Yes—with a few caveats.

Creatine is one of the most-researched supplements on the planet. Decades of studies have shown it’s safe for long-term use in adults.

But here’s the fertility-specific take:

• Stick to creatine monohydrate (the OG, most-researched form)
• Typical dosing: 3–5g daily (ideally taken with food or post-workout)
• Always clear it with your doctor or fertility practitioner, especially if you’re on meds or have kidney issues

Bonus: You don’t need to cycle it or “load” it like a bodybuilder. We’re building babies, not biceps.

Who Might Benefit Most?

• Women over 30 (hello, mitochondria support)
• Vegans and vegetarians (less dietary creatine = bigger potential benefit)
• Anyone dealing with low energy, brain fog, or inflammation while TTC
• Women in high-stress or high-performance lifestyles (yes, we’re looking at you, Ms. Type A.)

But Will Creatine Actually Make Me More Fertile?

It’s not a magic bullet. (Sorry. We looked.)

But it’s a key part of your fertility ecosystem—supporting the metabolic engine behind everything from egg maturation to uterine lining prep.

If you’re already doing acupuncture, supporting hormone balance, managing stress, and eating nutrient-dense foods? Creatine might be that final jigsaw piece.

Creatine Is For Women.

We’re calling it now: Creatine is about to go viral in women’s wellness.

It’s science-backed, safe, relatively inexpensive, and—unlike some $90 fertility powders—actually does something.
