The back of your creatine tub is not lying to you exactly.

Worse.

It is telling one tiny truth so confidently that half the room mistakes it for the whole gospel.

Five grams.

Printed everywhere.

Repeated by every coach.

Tossed into shaker bottles by lifters who read one label in 2008 and have been operating on that fossilized dosage scripture ever since.

For muscle? Fine.

But for everything creatine is being used for now?

The 5-Gram Cult

Creatine began its supplement life as a meathead miracle: more phosphocreatine in muscle, faster ATP regeneration, better repeated high-intensity work, bigger training outputs, better strength and power adaptations over time.

That story is real.

For skeletal muscle saturation, 3-5 grams per day works for most people if they take it consistently. Muscle is a greedy little warehouse for creatine. Feed it long enough and the shelves fill.

No drama or moon-phase loading ceremony required.

...but other tissue does not behave like skeletal muscle.

The brain is even weirder - a locked basement club with a suspicious bouncer, poor lighting, and a mitochondria DJ playing industrial music until 3 AM.

That is where the 5-gram default starts to wobble.

Bone: The Slow, Stubborn Fortress

Look at the postmenopausal bone data.

Chilibeck and colleagues ran a two-year randomized trial using creatine at 0.14 g/kg/day, paired with resistance training and walking in postmenopausal women (Chilibeck et al., 2023).

That is not a cute little 3-gram fairy sneeze.

For an 80 kg person, 0.14 g/kg/day is about 11 grams daily.

The big headline was not a magical BMD explosion. Femoral neck, total hip, and lumbar spine bone mineral density did not significantly change.

Useful finding, not hype confetti.

However, the creatine group improved several bone geometric properties - cross-sectional area, cortical thickness, and structural features that matter for how bone handles force. Walking speed improved too.

Now compare that with Sales and colleagues: two years, older postmenopausal women, 3 grams per day, no resistance training intervention, and basically nothing meaningful happened for bone health (Sales et al., 2020).

That does not mean creatine is useless for bone.

It means dose, tissue, training, and population matter. Welcome to physiology, where the details are not garnish - they are the whole damn meal.

Brain: The Slow-Loading Weirdos Upstairs

Inside the skull, creatine uptake is slower and smaller than muscle uptake.

You can flood skeletal muscle relatively quickly.

Brain tissue is more like trying to sneak extra batteries into a government bunker guarded by enzymes, transporters, and bureaucracy.

Candow and colleagues have argued that higher or longer dosing strategies may be needed for brain bioenergetics than for basic muscle saturation, with protocols such as 0.10-0.14 g/kg/day or higher-dose short-term approaches showing up in the discussion (Candow et al., 2024).

The exact brain dose is not locked down yet.

Anyone pretending otherwise is selling certainty-flavored cotton candy.

But the direction is obvious enough for practical coaching: when your goal expands from "fill muscle" to "support muscle plus bone plus brain," 5 grams may no longer be the most rational default.

The Practical Dose Map

Here is how I would think about it without turning your kitchen counter into a pharmacy crime board.

Young lifter chasing strength, power, and hypertrophy: 5 g/day is fine.

Bigger athlete with more muscle mass: 5-10 g/day may make more sense.

Masters athlete over 40 who wants muscle, bone, and brain support: around 10 g/day, split as two 5-gram servings with meals.

Contact sport athlete: 10 g/day is a rational year-round baseline in my biased nerdy opinion, especially if the goal is chronic tissue saturation before the bad day happens.

Coach using creatine for bone health in masters clients: do not pretend 3 grams alone is the same intervention as 0.10-0.14 g/kg/day plus lifting. That is like comparing a kitchen match to a flamethrower because both technically involve fire.

The GI Reality Check

Bigger doses can be harder on the gut if you slam them all at once like a pre-workout goblet from the Temple of Bad Decisions.

Split the dose.

Take it with meals.

Scale gradually if your stomach is dramatic.

Creatine monohydrate still wins. The fancy forms mostly exist so supplement companies can dress up a boring effective molecule in a velvet cape and charge you nonsense rent.

What This Means For You

The 5-gram recommendation is not wrong.

It is incomplete.

For muscle-only goals, keep it simple.

Once bone, brain, aging, contact sports, shift work, or larger body size enter the chat, dosage should stop being a label-reading reflex and start becoming a goal-matched decision.

The full prescribing map - by sport, population, tissue target, and body weight - lives in Section 13 of the Complete Creatine Manual.

Section 8 breaks down bone.

Brain gets the full treatment in Section 9.

Section 12 handles the myth dumpster fire.

The manual is $37. Code DRMIKE drops it to $27 through Monday at midnight PST.

Much love and correctly sized scoops,

Dr Mike

PS - The 0.14 g/kg/day dose works out to about 11 g/day for an 80 kg athlete. Most will need to split that dose, however some can handle monster does at once, and if so, go for it.
