Question 1

Does creatine actually work?

Accepted Answer

Yes — creatine is one of the most extensively studied and consistently effective sports supplements. Over 700 peer-reviewed studies support its safety and efficacy. It works by increasing phosphocreatine stores in muscle, which allows for faster regeneration of ATP (the primary energy currency of cells) during high-intensity, short-duration efforts. Meta-analyses show average strength increases of 5–15% and muscle mass gains of 1–2 kg over 4–12 weeks when combined with resistance training.

Question 2

Do I need to do a loading phase?

Accepted Answer

No — loading is optional. The loading phase (20g/day for 5–7 days, split into 4 doses) saturates muscle creatine stores quickly. Skipping loading and taking 3–5g/day produces identical results after 3–4 weeks — it simply takes longer to fully saturate stores. If you want faster results (particularly for an upcoming competition or training block), loading is useful. For most people, the standard approach of 3–5g/day without loading is simpler and produces less initial water retention.

Question 3

When is the best time to take creatine?

Accepted Answer

The timing of creatine is largely irrelevant because it works by increasing stored creatine over time, not acutely. However, recent meta-analyses suggest a slight advantage to post-workout creatine timing, possibly due to increased muscle insulin sensitivity after exercise improving creatine uptake. Taking creatine with a carbohydrate-containing meal increases muscle uptake due to insulin's role in creatine transport. Consistency matters far more than timing.

Question 4

Is creatine safe for kidneys?

Accepted Answer

Yes, in healthy individuals. This concern stems from creatine's conversion to creatinine, a waste product measured in kidney function tests. In people with healthy kidneys, supplementation raises creatinine levels but does not cause kidney damage — this has been confirmed in long-term studies including one following subjects for 21 months. People with pre-existing kidney disease should consult a doctor before supplementing. The International Society of Sports Nutrition categorises creatine monohydrate as safe, effective, and ethical.

Question 5

What is the best form of creatine?

Accepted Answer

Creatine monohydrate is the most well-studied, cheapest, and most effective form. More expensive alternatives — creatine HCl, ethyl ester, Kre-Alkalyn, and buffered creatine — have not been shown to outperform monohydrate in direct comparisons despite marketing claims. Creatine HCl may have slightly better solubility and may reduce bloating in those sensitive to monohydrate. For most people, unflavoured creatine monohydrate powder at 3–5g/day is the optimal choice.

Question 6

Will creatine cause water retention or bloating?

Accepted Answer

Creatine causes intramuscular water retention — it draws water into muscle cells, which is part of the mechanism behind its performance and muscle-building effects. This is not subcutaneous bloating; it is inside the muscle and contributes to the slightly fuller muscle appearance creatine users notice. During a loading phase, you may gain 0.5–2 kg of scale weight within the first week, almost entirely water. This is not fat and reverses within 2–4 weeks of stopping supplementation.
