Creatine for Women: The Daily Dose for Muscle, Brain Health, and High-Intensity Training

Sims begins by distancing creatine from its bodybuilding 'loading' image, which she says turned many women away. She explains that the body's liver produces only 2-3 g per day, but modern dietary patterns—amplified by diet culture and GLP-1 appetite suppression—make it nearly impossible to get the extra needed for saturation (the equivalent of 20 chicken breasts daily). The brain's reliance on glucose over lactate due to a lack of high-intensity work creates a metabolic deficit that creatine can offset. The result is not muscle bulk but broader support for energy metabolism and cognitive function. She frames this as an essential daily practice for women, not an optional athletic supplement.

Stacy describes how modern life bombards us with sight and sound—billboards, alerts, social media—and notes that even asking someone to drive without music is jarring. This environment sustains a chronic sympathetic state. Her airplane mode day creates a deliberate 'off' period where the brain isn't chasing digital pings. She emphasizes the mental reframe: 'This device is controlling you. You don't have control over it.' She applies the same principle to her teenage daughter, limiting phone use and banning social media, observing how fast addiction takes hold. The practice is as much about agency as about recovery, and she reports that friends who adopt it feel significantly better.

Sims relates that many women have lost body intuition, including hunger and fullness cues, partly because they eat in front of screens and rely on external data. The Apple Watch example—a woman wondering if she needed a night walk because of 5,000 missing steps after a full day of training and activity—illustrates the confusion. Sims bluntly says the number means nothing, it's arbitrary. The device's original purpose, she argues, was to nudge people out of prolonged sitting, not to set a rigid finish line. This protocol is about restoring internal calibration: you should move when your body says, not when the watch says you haven't met a manufactured quota.

Sims explains that every fast-energetic system in the body relies on the ATP-CP cycle and therefore uses creatine. A small daily dose (3-5 g) fully saturates all these tissues—not just muscle—and enhances their function. She ties this to brain health: the brain's preferred fuel is lactate, produced during high-intensity exercise, but as people avoid that intensity, the brain becomes overly dependent on glucose and its metabolism can falter. Creatine provides a metabolic boost, supporting neuroplasticity and cognitive function. The practical need is amplified by modern dietary patterns: women eat less creatine-rich food (meat) due to diet culture, and the rise of GLP-1 agonists makes them too full to consume enough. The liver manufactures only about 2-3 g/day, so supplementation is often necessary to reach the saturation threshold.

Sims identifies a pervasive 'tired but wired' state driven by constant sensory bombardment—notifications, billboards, social media—and a societal lack of stopgaps for calm. She notes that even asking someone to drive without music or noise feels aversive. By setting aside one full day (Saturday) on airplane mode, she gives her nervous system a break from the immediacy of alerts. Friends who have adopted it report feeling dramatically better. The key, she argues, is the mindset shift from being controlled by the device to taking control over it. She extends the principle to her teenage daughter, enforcing time limits and no social media, observing how quickly addiction forms. The airplane mode day is therefore both a personal practice and a recommendation to reclaim autonomy.

Sims describes a broader loss of intuition: people eat in front of screens and ultra-processed foods, so they no longer register fullness; they rely on watches to tell them when to move, so they lose the internal sense of needing activity. She recounts receiving an email from a woman who had trained and worked all day but was 5,000 steps short of closing her Apple Watch ring, asking if she should go for a walk at night. Sims's reply: 'No, that means nothing. It's just arbitrary.' Instead, the watch should be used only to prompt incidental movement out of a sedentary spell—getting up from the desk—not to quantify the day's total. The underlying message is profound: women need to reclaim their body's signals over algorithm-generated targets, because the data overload is contributing to the same sympathetic stress and disconnection the device is ostensibly meant to solve.
