Creatine Monohydrate Dosage Calculator
Use your body weight to estimate a research-based creatine dose for either a loading protocol or a simple daily maintenance protocol.
How this creatine dosage calculator works
This calculator is based on common evidence-backed creatine monohydrate dosing guidelines used in sports nutrition research. It uses body weight to estimate your dose, then converts it into a practical daily recommendation.
- Loading phase: approximately 0.3 g/kg/day for 5-7 days, split into 4 smaller doses.
- Maintenance phase: approximately 0.03 g/kg/day long-term.
Most people can simplify this to 3-5 g/day for maintenance, but larger athletes may benefit from slightly more.
Loading vs. no-loading: which should you choose?
Option 1: Loading phase + maintenance
If you want muscle creatine stores to rise quickly, a short loading phase is the fastest route. You’ll usually take four smaller doses across the day to improve comfort and absorption, then drop to a lower maintenance intake.
- Good for people wanting faster saturation.
- Can increase risk of temporary bloating or mild GI discomfort if taken in large single servings.
Option 2: Maintenance only (no loading)
You can skip loading and simply take a consistent daily dose. This method still works—it just takes longer (typically a few weeks) to reach full intramuscular saturation.
- Simple and easy to stick with.
- Often better tolerated for sensitive stomachs.
Best practices for taking creatine
- Use creatine monohydrate (most studied form).
- Take it daily, including rest days.
- Timing matters less than consistency, but many people take it with meals or post-workout.
- Stay hydrated and spread intake through the day during loading.
- Measure accurately with a scale when possible.
Example dosage estimates
60 kg (132 lb) person
Maintenance is about 1.8 g/day by formula; practically, many choose 3 g/day.
75 kg (165 lb) person
Maintenance is about 2.3 g/day by formula; practically, around 3-4 g/day is common.
90 kg (198 lb) person
Maintenance is about 2.7 g/day by formula; practically, around 4-5 g/day is common.
Safety and side effects
Creatine is one of the most studied performance supplements and is generally considered safe for healthy adults when used as directed. Still, there are situations where you should check with a clinician first.
- Known kidney disease or reduced kidney function
- Pregnancy or breastfeeding
- Use in minors without medical or professional guidance
- Concurrent medications that affect hydration or kidney function
Frequently asked questions
Do I need to cycle creatine?
No strict cycling is required for most people. Many users take it continuously at maintenance doses.
Can I take creatine on rest days?
Yes. Daily consistency is recommended to keep stores elevated.
Is creatine only for bodybuilders?
No. It may benefit strength, power, high-intensity performance, and potentially cognitive outcomes in certain contexts.
