Creatine Dosage Calculator: Find Your Optimal Dose (Loading & Maintenance)
Use our free Creatine Dosage Calculator to instantly determine your ideal daily creatine intake for both loading and maintenance phases. Designed using science-backed formulas, this calculator helps you supplement safely, effectively, and with precision, no guesswork required.
Enter your current body weight. Click the unit button to switch between kg and lbs.
How It Works
This calculator uses scientifically validated formulas based on research from the Journal of the International Society of Sports Nutrition (JISSN):
- •Loading Phase: 0.3 g/kg/day for 5-7 days rapidly increases muscle creatine stores
- •Maintenance Phase: 0.03 g/kg/day (typically 3-5 g/day) sustains elevated levels long-term
The loading phase is optional. You can skip it and start with maintenance, which will achieve the same saturation in 3-4 weeks.

Read Your Results
Your personalized results will include:
- •Maintenance Dose (per day): The optimal daily dose to maintain full muscle saturation.
- •Loading Dose (optional): A short-term higher dose (5–7 days) to speed up muscle creatine levels.

Example Scenarios – How the Calculator Works
To help you understand the formula, here are three practical examples:
| Weight (kg) | Weight (lbs) | Loading Dose (0.3 g/kg) | Maintenance Dose (0.03 g/kg) |
|---|---|---|---|
| 60 kg | 132 lbs | 18 g/day (for 5–7 days) | 1.8 g/day |
| 80 kg | 176 lbs | 24 g/day (for 5–7 days) | 2.4 g/day |
| 100 kg | 220 lbs | 30 g/day (for 5–7 days) | 3.0 g/day |
Alice weighs 60 kg. She chooses to follow a loading phase:
- •Loading: 18 g/day for 5–7 days
- •Maintenance: 1.8 g/day thereafter
Rahul weighs 80 kg. He skips loading and starts with maintenance only:
- •Maintenance: 2.4 g/day consistently
David weighs 100 kg. He prefers to load quickly:
- •Loading: 30 g/day for 5 days (split into 4 servings of 7.5 g)
- •Maintenance: 3 g/day after the loading phase
Tip: Split large doses into smaller servings (e.g., morning, noon, evening) to reduce stomach discomfort and improve absorption.
What Is Creatine and Why Does Dosage Matter?
Understanding Creatine
Creatine is a naturally occurring compound found in muscles. It helps produce ATP (adenosine triphosphate), the body's primary energy source during short, high-intensity activities like sprinting or weightlifting.
Why Correct Dosage Is Important
The human body stores a limited amount of creatine. Supplementation increases this reserve, enhancing performance, muscle recovery, and strength. However, the correct dosage ensures:
- •Optimal muscle saturation without wastage
- •Reduced bloating or digestive issues
- •Consistent long-term benefits
Research-Based Dosage Guidelines
According to the Journal of the International Society of Sports Nutrition (JISSN):
- •A loading phase of 0.3 g/kg/day for 5–7 days rapidly increases muscle creatine stores.
- •A maintenance dose of 0.03 g/kg/day sustains these elevated levels long-term.
- •This translates roughly to 3–5 g/day for most adults.
Maintenance vs. Loading Phase: Which Is Right for You?
Purpose:
To fill muscle stores quickly.
Dosage:
0.3 g/kg/day (~20–25 g/day for average adult).
Duration:
5–7 days, then switch to maintenance (3–5 g/day).
Pros:
Rapid results, visible muscle fullness.
Cons:
May cause temporary water retention or mild stomach discomfort.
Purpose:
Gradually saturate muscles without a high initial dose.
Dosage:
3–5 g/day consistently.
Pros:
Gentler on the body; no loading hassle.
Cons:
Takes ~3–4 weeks to achieve full saturation.
Expert Tip: Beginners or those sensitive to supplements can skip the loading phase. Long-term benefits remain the same when consistent.
Creatine Monohydrate vs. Other Forms
| Type | Pros | Cons |
|---|---|---|
| Creatine Monohydrate | Most researched; affordable; effective | Minor water retention possible |
| Creatine HCL | Dissolves better in water; smaller dose required | More expensive; fewer studies |
| Buffered Creatine (Kre-Alkalyn) | Claims less bloating | No proven advantage over monohydrate |
| Creatine Ethyl Ester | Marketed as fast-absorbing | Research shows poor stability and efficiency |
| Micronized Creatine | Finer texture, better mixing | Slightly pricier; same effectiveness |
Verdict: Stick with Creatine Monohydrate, it's safe, cost-effective, and backed by decades of scientific research.
Supplementation Tips & Best Practices
Take creatine daily for best results, skipping days reduces effectiveness.
Drink plenty of water (2–3 liters/day) to support muscle function and prevent dehydration.
Insulin helps transport creatine into muscles, take it with a meal or shake.
Divide loading doses into smaller servings (morning, noon, evening).
Look for "Creapure®" certified creatine monohydrate for purity and safety.
Quick Reference: Dosage by Body Weight
| Body Weight | Loading Dose (5–7 days) | Maintenance Dose |
|---|---|---|
| 50 kg | 15.0 g/day | 1.5 g/day |
| 60 kg | 18.0 g/day | 1.8 g/day |
| 70 kg | 21.0 g/day | 2.1 g/day |
| 80 kg | 24.0 g/day | 2.4 g/day |
| 90 kg | 27.0 g/day | 2.7 g/day |
| 100 kg | 30.0 g/day | 3.0 g/day |
Safety, Disclaimer & When to Consult a Doctor
The Creatine Dosage Calculator provides evidence-based recommendations, but it's not medical advice.
- Always consult a healthcare provider before starting any supplement, especially if you have kidney, liver, or heart conditions.
- Pregnant or nursing women should avoid supplementation unless prescribed by a doctor.
- Keep dosage within safe limits (3–5 g/day for maintenance).
Remember, supplements enhance, not replace, a healthy diet, hydration, and regular exercise.
