Creatine in 2025: everything you thought you knew that turns out to be wrong

The loading phase is not necessary

The creatine loading protocol — 20 grams per day for 5 to 7 days followed by a maintenance dose — was designed for speed of saturation. It works. But taking 3 to 5 grams daily without a loading phase produces the same result in 28 days with far less gastrointestinal stress. Unless you have a competition in two weeks, loading offers no meaningful advantage over steady daily dosing.

Creatine does not cause water retention in the way you think

Creatine draws water into muscle cells — specifically intracellular fluid. This is not the same as subcutaneous water retention that makes muscles look soft or blurs definition. The water increase is inside the muscle fibre, which actually makes the muscle appear fuller and better hydrated. The weight gain (typically 1 to 2 kg in the first few weeks) is largely this intracellular fluid.

Who benefits most: not who you expect

Most people think of creatine as a tool for powerlifters and bodybuilders. The evidence base is actually broadest for athletes involved in repeated high-intensity efforts with brief recovery — team sports, interval training, multiple sprint disciplines. Endurance athletes at altitude also benefit via improved oxygen-carrying efficiency. The population that sees the most dramatic results? Older adults, where creatine significantly slows age-related muscle loss.

Creatine monohydrate vs every other form

Creatine ethyl ester, buffered creatine, creatine HCl — all claim superior absorption over monohydrate. None have demonstrated superior outcomes in head-to-head research. Creatine monohydrate remains the most studied, cheapest and best-evidenced form. The premium alternatives are marketing. A clean, unflavoured monohydrate like Keforma's Creatine is all the evidence supports.

Timing: morning, pre or post-workout?

The timing of creatine intake has been studied extensively and the findings are underwhelming. Post-workout may have a marginal edge over pre-workout, but the effect is small enough that consistency of daily intake matters far more than precise timing. Take it when it is easy to remember. Daily. That is the entire protocol.

The brain benefits you were not expecting

Creatine is not only stored in muscle — the brain maintains its own creatine pool, which is depleted by cognitive effort, sleep deprivation and mental stress. Research on creatine supplementation in cognitively demanding situations (sleep-deprived subjects, ageing populations, high-stress work environments) shows measurable improvements in working memory, processing speed and mental fatigue resistance. This is an active and growing area of research.

The one thing creatine does not do

Creatine is not an anabolic hormone. It does not directly stimulate muscle protein synthesis. What it does is increase phosphocreatine stores in muscle, allowing more work to be completed in training before fatigue sets in. The muscle growth comes from the additional training volume that creatine enables — not from the creatine itself. It is a performance enhancer that creates the conditions for hypertrophy, not a hypertrophy drug.
