The Two Proven Approaches
Nearly every creatine study uses one of two protocols. Both work. They differ only in speed.
Option A: Load, then maintain (fast)
Take about 0.3 g per kg of body weight per day (roughly 20 to 25 g for most adults), split into 4 or 5 doses, for 5 to 7 days. Then drop to 3 to 5 g per day. Muscles reach full saturation within about a week. The tradeoff: a little more early water weight, and four shaker bottles a day is annoying.
Option B: Steady dose (simple)
Take 3 to 5 g per day, every day, from the start. You reach the same full saturation in about four weeks instead of one. Most people choose this, because one serving a day is a routine you will actually keep.
For reference, a 70 kg (154 lb) person loading at 0.3 g/kg takes about 21 g per day during the loading week. Maintenance at 0.03 g/kg lands at about 2 g, but the research convention rounds up: 3 to 5 g daily covers nearly everyone, including larger athletes.

Two more tools in the kit: the dose calculator gives you both protocols tuned to your own weight, and the cost and supply calculator turns any label into cost per 5 g and days of supply.
Timing: Take It When You Will Remember
This is the most overthought part of creatine. Studies comparing pre-workout vs post-workout timing find small or inconsistent differences, with a slight lean toward post-workout alongside food. The honest summary: timing matters far less than consistency. Pick the moment in your day you will not skip, and anchor it there: morning coffee, post-workout shake, dinner.
How to Mix It
- Micronized powder dissolves in anything: water, juice, a protein shake, oatmeal. Warm liquids dissolve it fastest.
- With food or carbs may slightly improve uptake, thanks to insulin helping shuttle creatine into muscle. A meal or a glass of juice is plenty; you do not need a sugar-loading ritual.
- Caffeine is fine alongside creatine in normal amounts. The old warning about caffeine canceling creatine came from one small, short study and has not held up.
- Do not dry-scoop. It is unpleasant, a choking hazard, and gains you nothing.
One rounded teaspoon in your morning shake is the whole routine.
Brain-Focused Dosing: What the Research Suggests
Standard 3 to 5 g daily doses saturate muscle well, but the brain is harder to saturate. Some researchers studying cognitive effects have used higher protocols, roughly 15 to 20 g per day for several days, then 5 to 10 g daily, particularly in studies of sleep deprivation and older adults.
Important context: this is early science, not a recommendation. Higher doses mean more chances of stomach discomfort, and the cognitive benefits at these doses are still being mapped. If brain benefits are your goal, the responsible path is to start with the standard 3 to 5 g, give it a month of consistent use alongside good sleep, and discuss anything higher with your doctor first.
What About Cycling?
You do not need to cycle creatine. Long-term studies, some running for years, show continued safety with daily use, and there is no evidence that breaks improve results or "reset" anything. If you stop, muscle creatine drifts back to baseline over three to four weeks. If you restart, you simply saturate again.
Safety Notes Worth Reading
- Healthy adults: a 2025 analysis of 685 clinical trials found no significant difference in side effects versus placebo, including kidney and liver markers.
- Kidney disease: the safety data covers healthy people. If you have kidney issues, talk to your doctor first.
- Pregnancy and breastfeeding: not enough human research exists. Ask your doctor; do not guess.
- Teens: creatine is widely used by teen athletes, but dosing should involve a parent and ideally a doctor or dietitian.
- Medications: if you take drugs that affect the kidneys (certain blood pressure meds, NSAIDs used heavily), check with your doctor or pharmacist.

Not medical advice
Dosing protocols above come from published research and are starting points, not prescriptions. Talk to your doctor before beginning supplementation, especially with a medical condition or medication.
Our Dosing-Friendly Picks
Any plain creatine monohydrate works for these protocols. Our defaults:
Optimum Nutrition Micronized Creatine Monohydrate
- One rounded teaspoon (5 g) equals the standard daily dose: no measuring math, though only a kitchen scale gives exact grams
- Micronized for clean mixing at any dose
Momentous Creatine Monohydrate
- Batch-tested purity for anyone who wants verification
- Same 5 g per serving, per the label
- Formulation note, checked 2026-10-03: Momentous replaced Creapure with its own Signature Spec creatine in powders starting June 16, 2026. This 30-serving Amazon SKU is still advertised as Creapure, so it may be older inventory; the current flagship on the Momentous site is a 90-serving Signature Spec powder. Check the tub label when it arrives.
