Creatine Dosage Chart
Creatine monohydrate is one of the most researched sports supplements. It replenishes phosphocreatine in muscle cells, supporting explosive strength and high-intensity exercise. An optional 5–7 day loading phase saturates muscles faster; maintenance dosing achieves the same result over 3–4 weeks.
Creatine Dosage by Age Group
| Age Group | Age Range | Dose Range | Notes |
|---|---|---|---|
| Adults — maintenance (no loading) | 18–64 years | 3–5 g | 5 g/day is the standard evidence-based dose |
| Adults — loading phase | 18–64 years | 20–25 g | Split into 4–5 doses; 5–7 days only |
| Adults — after loading (maintenance) | 18–64 years | 3–5 g | Continue indefinitely |
| Seniors (65+) — cognitive + muscle | 65+ years | 3–5 g | Emerging data on cognitive benefits in older adults |
Weight-Based Dosage Calculator
Enter your weight to calculate a personalized Creatine dose based on body weight. 0.1 g per kg of body weight per day (maintenance). A 75 kg person = 7.5 g/day (upper end). Most research uses 5 g/day for adults regardless of weight.
When and how to take Creatine
Timing is less critical than consistency. Post-workout with carbohydrates may slightly improve uptake (insulin-mediated transport). Pre-workout is also effective. Daily timing matters more than workout proximity.
Available Forms
Gold standard. Most studied. Cheapest. Effective.
Micronized version dissolves better in water
Higher solubility, may require smaller dose. Less bloating reported.
Dose: 0.75–1.5 g/day vs. 5 g monohydrate
Marketing claims of superior absorption are not supported by research.
No evidence of advantage over monohydrate
Safety Cautions
- Creatine is considered safe for healthy adults at standard doses (3–5 g/day).
- Loading phase (20–25 g/day) may cause gastrointestinal discomfort — split into 4–5 smaller doses.
- Creatine increases muscle water retention; weight gain of 1–2 kg in first week is water, not fat.
- Avoid if you have kidney disease — discuss with a physician.
- Ensure adequate hydration; creatine draws water into muscle cells.
- Not recommended for children under 18 years in sports supplement context.
Frequently Asked Questions
How much creatine should I take per day?
The standard maintenance dose is 3–5 g of creatine monohydrate per day. A 5 g serving (approximately one teaspoon) is the most commonly studied and effective dose for most adults. Loading at 20 g/day for 5–7 days speeds up muscle saturation but is not required.
Should I do a creatine loading phase?
Loading is optional. It saturates muscle creatine stores in 5–7 days instead of 3–4 weeks. If you want quicker results, load at 20 g/day (4 × 5 g) for 5–7 days, then drop to 5 g/day. If you are patient, just start with 5 g/day — you get the same results eventually.
What is the creatine HCl dosage?
Creatine HCl is typically dosed at 0.75–1.5 g/day due to its higher solubility. Some protocols use 750 mg per dose. However, research comparing creatine HCl to monohydrate at equivalent saturation doses does not show a clear performance advantage.
Is creatine safe for seniors?
Yes. Multiple studies support creatine supplementation in adults over 65 for maintaining muscle mass, bone density, and possibly cognitive function. Standard dose of 3–5 g/day applies. Seniors with kidney issues should consult a physician first.
