You weigh 90 kg and are wondering how much creatine you should take? Here are specific calculations, practical guidelines, and tips that you can implement right away.
How much is that exactly: basic calculations for 90 kg
The standard, scientifically applied values are: loading 0.3 g/kg of body weight per day for 5–7 days and maintenance 0.03 g/kg per day. For a person weighing 90 kg, this means:
- Loading: 0.3 g × 90 kg = 27 g/day (for 5–7 days)
- Maintenance: 0.03 g × 90 kg = 2.7 g/day (after saturation of reserves)
In practice, we round up to convenient doses: loading 25–30 g/day (divided), then maintenance 3–5 g/day.
How to spread the dose throughout the day?
Creatine taken in large amounts at once can cause stomach discomfort. For 90 kg, I suggest the following distribution during the loading phase:
- 5 servings of 5 g + 1 serving of 2–3 g (total ~27–30 g) — best spread out every 3–4 hours
- or 4 servings of ~6.5–7 g (if you use a 6–7 g scoop)
After the saturation phase, one serving per day is sufficient: preferably 3–5 g, depending on your preferences and tolerance.
Do I have to do the loading phase?
No. An alternative is to take 3–5 g/day continuously without a loading phase. In this case, your muscles will reach full saturation after about 3–4 weeks instead of 5–7 days. This is a safe and simpler method, especially for people who are sensitive to larger doses at once.
What form of creatine?
Based on research and clinical practice, creatine monohydrate remains the best choice. It is inexpensive, effective, and well-studied. Other forms (micronized monohydrate, HCl) may be advertised as "better," but the advantage in results for most people is marginal.
When to take creatine?
- On training days: after training, with a meal containing carbohydrates and protein. This can facilitate the transport of creatine to the muscles.
- On non-training days: any time, e.g., with a meal. It is important to take it regularly.
Practical table: dosage schedules for 90 kg
| Scheme | Phase | Dosage for 90 kg | Comments |
|---|---|---|---|
| Scaled loading | Loading (5–7 days) | ~27 g/day (0.3 g/kg) | Divide into 4–6 servings; quickly saturates reserves |
| Standard store-bought | Loading | 4 × 5 g = 20 g/day | Popular, slightly lower than 0.3 g/kg, also works |
| Maintenance (weight) | Maintenance | ~2.7 g/day (0.03 g/kg) | Most precise; can be rounded up to 3 g |
| Maintenance (practical) | Maintenance | 3–5 g/day | Simple, no complications; works for most people |
| No loading | No loading phase | 3–5 g/day | Full saturation after ~3–4 weeks |
Measuring spoons and specifics: how much is one measuring spoon?
A typical scoop for monohydrate is ~5 g. For 90 kg:
- Loading 27 g ≈ 5 g × 5 + 2 g (closest: 5 × 5 g = 25 g; or 6 × 5 g = 30 g)
- Maintenance 2.7 g ≈ 1/2 scoop; in practice, we use 1 scoop (5 g) or 3 g (smaller scoop/teaspoon)
Safety and side effects
In healthy individuals, creatine supplementation at maintenance doses (3–5 g/day) is safe in the short and long term. The most common reactions are:
- weight gain due to water retention in the muscles (~1–2 kg),
- nausea or stomach discomfort when taking too large a dose at once,
- rarely: cramps in people who are dehydrated or have insufficient electrolyte intake.
If you have kidney disease, diabetes, or other serious medical conditions, discuss supplementation with your doctor and have follow-up tests. Creatine can increase blood creatinine levels, which can be misinterpreted as a deterioration in kidney function, so it is important to know your baseline results.
Sample plan for a 90 kg person
- Days 1–7 (loading option): 5 × 5 g in the morning, before noon, before training, after training, in the evening = 25 g; adjust one serving to ~2–3 g to reach ~27 g/day.
- Day 8+: 3–5 g once a day after training or with a meal.
- No loading option: 3–5 g daily; continue for at least 4 weeks — your muscles will be saturated.
FAQ
How long does it take for muscles to become saturated with creatine?
With loading: usually 5–7 days. Without loading: about 3–4 weeks at a dose of 3–5 g/day.
Do I need to drink more water with creatine?
Consume a normal amount of fluids. With loading, you may feel more thirsty. Stay properly hydrated, especially on training days.
Does creatine cause fat gain?
No. Early weight gain is mainly water in the muscles. Long-term strength and muscle mass growth depends on diet and training.
Can I take creatine with other supplements?
Yes — creatine works well with protein, carbohydrates, and most pre- and post-workout supplements. Avoid taking large doses of caffeine at the same time if you experience discomfort.
You weigh 90 kg — using the calculations described above and a simple plan, you will achieve muscle saturation without unnecessary complications. If you want, I can adjust the plan to your training and meal schedule.
