Creatine: What It Actually Does and Why It Might Be Worth Adding to Your Routine

If you have spent any time in the gym world lately, you have probably heard people talk about creatine. It gets mentioned constantly, and for good reason. It is one of the most researched supplements out there, and the research consistently backs it up.

Here is what you actually need to know.

What Creatine Is

Creatine is a compound your body already makes naturally, mostly stored in your muscles. It plays a direct role in how your muscles produce energy for short, intense bursts of effort, things like a heavy lift, a sprint, or the last few reps of a hard set. Supplementing with creatine simply increases the amount stored in your muscles beyond what your body makes on its own, which gives you more fuel in the tank for that kind of effort.

Who It Helps

Masters Athletes

As we age, we naturally lose muscle mass and strength, a process that speeds up without consistent resistance training. Creatine has been shown to support strength and lean muscle mass in older adults, especially when paired with training. For masters lifters trying to stay strong and competitive, this is one of the few supplements with real evidence behind it.

Postnatal Clients

Rebuilding strength after pregnancy is its own process, and energy availability matters a lot here. Creatine may help support strength recovery and training capacity during this phase. As always, if you are pregnant, breastfeeding, or have any medical concerns, talk with your doctor before starting.

Hyrox and General Population Clients

Whether you are training for a Hyrox event or just trying to get stronger and feel better day to day, creatine can support your ability to push through high effort intervals and recover between them. It also has some early but promising research around cognitive function and recovery from mental fatigue, which matters when you are stacking hard training sessions with a busy life.

How to Take It

• Type: Creatine monohydrate. It is the most studied form and there is no strong evidence that fancier, more expensive versions work better.

• Dose: Typically 3 to 5 grams per day, taken consistently. You do not need a loading phase, though some people choose one to saturate muscle stores faster.

• Timing: Timing matters far less than consistency. Take it whenever it fits your routine.

• Mixing: It dissolves in water, coffee, or your shake. No special requirements.

Common Concerns

A lot of people worry creatine will cause bloating or kidney issues. For healthy individuals, the research does not support kidney damage as a real risk. Some people do experience minor water retention early on, which typically levels out. If you have any pre-existing kidney condition, check with your doctor first.

Bottom Line

Creatine is not a magic pill, but it is one of the few supplements with genuinely strong research behind it for strength, muscle mass, and performance across a wide range of ages and goals. If you are training consistently and want to get the most out of that effort, it is worth considering.

As always, supplements support your training, they do not replace it. If you have questions about whether creatine is right for you, bring it up at your next session.
