Creatine Monohydrate
Also known as: Creatine
Creatine monohydrate is among the most studied supplements for exercise performance and muscle. It is commonly used to support strength and high-intensity training. It is also being explored for cognitive contexts, where evidence is more preliminary.
Snapshot
What this page can tell you: NIH ODS findings on what creatine may help, the amounts studied, and its side-effect/safety profile.
What it cannot: That creatine builds muscle for you or suits your situation — it is studied for repeated short bursts of intense activity, not guaranteed results. Informational only.
🧩 Stack insights — how this fits into a schedule
Studied use and amounts — NIH ODS: creatine enhances performance in repeated short bursts of intense activity (e.g. sprinting, weightlifting). Studied amounts: a loading dose of ~20 g/day (4 portions) for 5–7 days, then 3–5 g/day — studied amounts, not a personal recommendation.
Safety and side effects — NIH ODS: creatine usually causes some weight gain from water retention; rare reactions include muscle stiffness, cramps, or GI upset. It is described as safe for healthy adults short-term and seemingly safe over several years. People with kidney conditions commonly still review it with a clinician.
Relationship insights are informational only — they describe what is commonly discussed or studied, not what you should take. Not medical advice; review your routine with a clinician or pharmacist.
📊 Studied dosing
Studied dose, not a personal recommendation. These are amounts used in specific studies or populations — not guidance for you.
| Intervention | Dose | Form | Frequency | Duration | Population | Outcome studied | Source | Limitations |
|---|---|---|---|---|---|---|---|---|
| Creatine (loading then maintenance) | ~20 g/day (4 portions) for 5–7 days, then 3–5 g/day | Monohydrate powder | Daily | Loading 5–7 days; maintenance ongoing | Healthy adults doing intense/intermittent exercise | Performance in repeated short bursts (sprinting, weightlifting) | NIH ODS — Exercise & Athletic Performance | Benefit is specific to short-burst activity; individual results vary; studied amount, not a personal recommendation. |

🕒 Timing
When: Anytime
Food: With or without food
Timing is flexible; consistency day-to-day matters more than exact timing.
💊 Common use range
3–5 g daily
A short higher-dose 'loading' phase is sometimes used; a steady daily amount is also common. Stay well hydrated.
Ranges are informational, not a recommended dose. Talk to a professional about what is right for you.
🤔 Worth considering?
Evidence vs. effort: Moderate evidence relative to burden
One of the better-studied performance supplements for short, high-intensity efforts. Low burden and generally well tolerated; the main noticeable effect for many is water-weight gain.
A general summary, not a recommendation. Whether something fits your situation is worth discussing with a healthcare professional.
⚠️ Commonly noted interactions (supplements)
None listed.
Often about absorption or timing rather than danger — separating doses is common. This list is not exhaustive.
🧭 Caution level
- Higher caution if you have kidney disease or a stone history
Caution level is an informational summary of commonly discussed caution categories and doses — not a safety rating, approval, or medical advice. Low caution does not mean safe for you.
🩺 Medication caution categories
None flagged here, but always review your full routine with a professional.
🏥 Surgery & procedure caution
Generally not a specific surgical concern, but tell your care team about all supplements.
If you have a procedure scheduled, bring your full supplement list to your surgical and anesthesia team. Do not stop prescribed medication unless your clinician tells you to. Do not start or stop supplements based only on this app.
✅ Quality checklist
- Prefer products with third-party testing or a certificate of analysis (COA).
- Check the label for the exact form and the elemental or active amount per serving.

🗣️ Questions for a professional
- Is Creatine Monohydrate appropriate alongside my medications and health history?
- Is there a test or check that would tell us whether I actually need it?
🛡️ Safety notes (source-reviewed)
- NIH ODS: creatine usually causes some weight gain from water retention.
- Rare reactions include muscle stiffness, cramps, or GI upset.
- Described as safe for healthy adults short-term and seemingly safe over several years; people with kidney conditions commonly still review it with a clinician.
⚖️ Evidence limitations
- Benefit is specific to repeated short-burst, high-intensity activity — not a general muscle-building guarantee.
❓ Frequently asked
What does creatine actually help with?
NIH ODS says creatine enhances performance during repeated short bursts of intense activity, like sprinting and weightlifting. It is not a general muscle-building guarantee.
Does creatine cause weight gain?
NIH ODS notes creatine usually causes some weight gain from water retention. Rare reactions include muscle stiffness, cramps, or GI upset.
🔬 Evidence snapshot
Some evidence suggests creatine may increase strength, power, and performance in repeated short bursts of high-intensity activity such as sprinting and weightlifting; it appears to be of little value for endurance sports.
🚦 Commonly noted cautions (auto)
Electrolyte / kidney caution items. Electrolytes such as potassium and magnesium interact with kidney function and several blood-pressure and heart medications. If any apply to you, consider discussing regular electrolyte use with a healthcare professional. This is a general caution, not a diagnosis or medical instruction.
🧪 Forms & quality
Needs evidence review — no source-reviewed information yet. We only show dose and monitoring details after they have been checked against reputable sources.
See the supplement glossary for what form names like "L-", chelated, or standardized extract mean.
📏 Dose & monitoring
No established UL. NIH ODS reports few safety concerns at typical doses (for example, about 20 g/day for up to 7 days, then 3-5 g/day for up to 12 weeks).
Evidence vs. burden: Moderate evidence relative to burden
😐 Commonly reported side effects
- Mild water retention, occasional digestive upset, weight increase from water
Non-exhaustive and individual.
🔄 Cycling & breaks
Cycling is not required; many use it continuously.
📅 Daily use notes
Consistent daily use is common. People with kidney concerns should talk to a professional first.
