Why Women are GLP-1 Users Are Suddenly Talking About Creatine
A practical, science guide to creatine for GLP-1 users worried about muscle loss.
The weighing scale has felt like a tiny platform of emotional terrorism ever since IVF pushed me to my heaviest weight. Weighing myself has been uncomfortable at best, but I wanted to make changes.
Which changes though?
In September 2025, I swallowed my anxiety and started gathering data. I committed to weight training four days a week and weighing myself once a week. For nine full months, I showed up, sweated, recovered, and lifted (heavy-ish).
The result? According to my smart scale, my lean muscle mass was steady or dropping.
DOMS (Delayed Onset Muscle Soreness) was ruining my life - even without getting to progressive overload. I was eating a decent amount of protein (ok, maybe it was a little bit low) - and the lack of progress made everything felt pretty pointless.
Sound familiar?
The Problem: I doing too much at once
I wanted to lose weight, drop fat, and build muscle simultaneously. In a body still recovering from intense hormonal shifts, that's a recipe for burnout.
After reading about how women and GLP-1 users are using more creatine - I fell straight into the rabbit hole, and it was a deep one! Creatine is one of the world’s most researched supplements - and this trend seems to have legs.
One month ago - I added it to my routine! And I have some results!
GLP-1 Weight Loss doesn’t have to be Lean Mass Loss
Your body burns both muscle and fat when you are dropping weight rapidly. When you lose a lot of muscle mass, you begin to feel physically weak, hit weight loss plateaus, and your basal metabolic rate plummets - making it harder for long term weight maintenance.
Now if you pair your GLP-1s with some weight training and enough protein- you get a magic formula. You start losing the fat weight while getting stronger - being able to recomposition your body to look leaner and feel stronger by the day.
Now if you are wanting to help yourself with a little boost in energy and to help you hit that gym a little bit harder - this is where creatine comes in!
What Actually Is Creatine? (It’s Not Just for Bodybuilders)
Creatine can be bitter, gritty and grainy, or it can be relatively flavorless if you do it right! After one month of consistency - my muscles are starting to look more toned, and I am able to lift more at the gym! (I am also vegetarian and creatine helps vegetarians immensely).
Creatine is a naturally occuring compound in our bodies that is made up of amino acids (build blocks of proteins) and it is basically used by our body to help our muscles generate ATP (Adenosine Triphosphate) - the energy our cells use. When we do things like lift weights, our ATP stores are depleted rapidly and creatine is like the battery backup that can help our bodies create more ATP quickly. This comes in clutch when you want to hit that extra last rep for faster muscle gains.
When you are eating significantly less food on a GLP-1, your cellular energy can take a massive hit. Creatine helps keep the lights on in your muscle tissue so you can actually train effectively.
Before you decide on adding creatine:
Because you are using a GLP-1 medication, you cannot just blindly throw supplements into your routine without understanding how they interact with your body. If you are wanting to add creatine to your regimen, talk with your doctor first! There are three critical medical realities they can help you navigate:
Baseline Kidney Monitoring: Creatine is filtered and excreted by your kidneys. Because GLP-1 medications significantly alter your fluid balance and appetite, your doctor needs to check your baseline kidney function before you start, ensuring your filtration system is running smoothly.
The “False Alarm” Lab Result: Because creatine naturally degrades into a waste product called creatinine, supplementing can cause a temporary spike in your blood work. To an unaware physician, elevated creatinine looks like a sign of kidney distress - even if your kidneys are perfectly healthy. Always tell your doctor you are taking creatine before getting blood work done so they don’t misinterpret your labs.
The Double-Dehydration Hazard: Creatine’s entire job is to pull water out of systemic circulation and lock it inside your muscle cells, it creates a massive demand for fluids. If you don’t aggressively scale up your water intake when starting creatine, you will rapidly worsen GI discomfort, trigger severe cramping, and accelerate constipation. If you are already dealing with these problems, work on those first before thinking about creatine.
Creatine, Water Weight, and the Temporary Plateau
Creatine can cause your body to hold on to more water (water retention)- causing your weight to go up or plateau initially. Seeing this in the first few weeks of using creatine can feel terrifying. But not all water retention is created equal.
The Bad Bloat (Extracellular): This is water that pools outside your cells, causing swollen fingers, a puffy stomach, and systemic discomfort. This is the kind of bloating from eating too much salt or PMS.
The Creatine Hydration (Intracellular): Creatine pulls water directly inside the muscle cells. This internal cellular hydration is good for you. It makes your muscles look firmer, fuller, and more toned. Hydrated muscle cells create the optimal biological environment for tissue repair and accelerated workout recovery. The severe muscle soreness I was experiencing reduced in the 1 month since I started creatine.
How to Take It Without the "Just Trust Me, Bro" Drama
There are 2 ways to start with creatine:
The aggressive, gym bro way
The gentle way
The GYM BRO WAY: Is called the “loading phase”. Protocol here is to take 20g of creatine everyday to load your body up with creatine for 5-7 days. And then you shift back down to the normal dosage (3-5g) of creatine per day.
For someone whose digestive system is already dealing with a lot - I would not recommend going this way. It can lead to stomach cramps, digestive distress and anxiety inducing fluid shifts.
The Gentler Approach: Ignore the gym bros. Take the slow and sustainable route. 3-5g of creatine every day. Slow and steady. Your muscles will take their own time to load up, but you will get there and you will have the same benefits - just might see them a week or two later.
Commit to a 30-day trial before you pass judgment.
Don’t obsess over a temporary minor scale fluctuation. Instead, ask yourself the questions that actually matter:
Are my workouts feeling stronger despite eating less?
Is my recovery time improving between training sessions?
Do my muscles look more supported and toned rather than “deflated”?
Is my daily stamina increasing?
The Bottom Line
GLP-1 medications are a miracle tool for weight management, but GLP1 + resistance training can help protect your metabolic health for the long haul. Resistance training ensures that when you cross the finish line of your weight loss journey, you have a strong, highly functioning, fat-burning metabolism waiting for you.
Creatine can help resistance training work better.
Now that you understand the science of why it works, you’re ready for the hard part: which creatine should you actually buy? In my next article (on Thursday), I’ll show you exactly how to spot the marketing lies, which forms are a total scam, and my official 10-brand product ranking so you don’t buy heavy metals or overpriced glitter.
