How Much Creatine Per Day? Exact Dosage by Weight (kg & lbs)
The most common creatine question is simple: how many grams should I take per day?
The honest answer: it depends on your body weight. The research-backed formula from the International Society of Sports Nutrition (ISSN) is 0.03g of creatine per kg of bodyweight per day for maintenance.
This page gives you exact numbers by weight so you don't have to do the math.
Quick Reference: Creatine Dosage by Weight
Maintenance Dose (Daily, Long-Term)
| Body Weight (kg) | Body Weight (lbs) | Daily Dose (g) |
|---|---|---|
| 50 kg | 110 lbs | 1.5g |
| 55 kg | 121 lbs | 1.7g |
| 60 kg | 132 lbs | 1.8g |
| 65 kg | 143 lbs | 2.0g |
| 70 kg | 154 lbs | 2.1g |
| 75 kg | 165 lbs | 2.3g |
| 80 kg | 176 lbs | 2.4g |
| 85 kg | 187 lbs | 2.6g |
| 90 kg | 198 lbs | 2.7g |
| 95 kg | 209 lbs | 2.9g |
| 100 kg | 220 lbs | 3.0g |
| 110 kg | 243 lbs | 3.3g |
| 120 kg | 265 lbs | 3.6g |
Note: Many coaches round up to a flat 5g/day for simplicity. This is safe and effective for most people 70kg+.
Loading Phase Dose (Days 1–7 Only)
If you want to saturate your muscles faster, use a loading phase first:
| Body Weight (kg) | Loading Dose (g/day) | Per Serving (4x daily) |
|---|---|---|
| 50–60 kg | 15g | 3.75g x 4 |
| 60–70 kg | 18g | 4.5g x 4 |
| 70–80 kg | 21g | ~5g x 4 |
| 80–90 kg | 24g | 6g x 4 |
| 90–100 kg | 27g | ~7g x 4 |
| 100+ kg | 30g (cap) | 7.5g x 4 |
After 7 days of loading, drop to the maintenance dose from the table above.
The Formula Explained
The ISSN formula for creatine dosage is:
Maintenance: 0.03g × bodyweight in kg = daily dose Loading: 0.3g × bodyweight in kg = daily loading dose (capped at ~25–30g)
For example, a 75kg person:
- Maintenance: 0.03 × 75 = 2.25g/day
- Loading: 0.3 × 75 = 22.5g/day (split into 4–5 servings)
For convenience, most people round to the nearest 0.5g or simply use a flat 3–5g/day, which is well within the effective range for most body weights.
Do You Need to Be Exact?
Not really. The dose-response relationship for creatine is relatively flat — taking 3g vs 5g per day both lead to full muscle saturation over time. The main effects of underdosing are:
- Slower time to full saturation
- Potentially slightly less benefit in very large athletes (100kg+)
Overdosing above your calculated amount mainly wastes creatine — your muscles can only store so much phosphocreatine, and the excess is excreted in urine.
Creatine HCl vs Monohydrate: Does the Dose Change?
Yes. Creatine HCl is more concentrated and absorbs more efficiently. The typical HCl dose is roughly half the monohydrate dose:
| Body Weight | Monohydrate Dose | HCl Dose |
|---|---|---|
| 60 kg | 1.8g | ~0.9g |
| 75 kg | 2.25g | ~1.1g |
| 90 kg | 2.7g | ~1.35g |

Activity Level Adjustments
The standard 0.03g/kg formula is calibrated for moderately active people. Some coaches adjust dosage based on training intensity:
| Activity Level | Dose Multiplier |
|---|---|
| Sedentary / light exercise | 0.025g/kg |
| Moderately active (3–5 days/week) | 0.03g/kg |
| Very active (6–7 days/week) | 0.035g/kg |
| Elite athlete (2x/day training) | 0.04g/kg |
These adjustments are modest — the difference between sedentary and elite athlete dosing for a 75kg person is only about 1g/day.
How Long Until It Works?
| Approach | Time to Full Saturation | Daily Dose |
|---|---|---|
| No loading | 3–4 weeks | 0.03g/kg/day |
| With loading phase | 5–7 days | 0.3g/kg/day × 7 days, then maintenance |
Both approaches reach the same endpoint: fully saturated muscles. The loading phase simply gets you there faster.
Should You Take More Creatine If You're Bulking?
Not necessarily. Your creatine needs are tied to your current lean muscle mass, not your caloric surplus. If you gain significant muscle over several months, you may want to recalculate your dose — but the adjustment will be small.

Water Intake With Creatine
As your muscles draw in more water with creatine supplementation, your hydration needs increase:
| Daily Creatine Dose | Minimum Daily Water |
|---|---|
| Up to 3g | 2.5 litres |
| 3–5g | 3.0 litres |
| Loading phase (15–30g) | 3.5–4.0 litres |
Adequate hydration reduces cramping, supports kidney function, and helps maximize creatine's performance benefits.
