❓Frequently Asked Questions
The evidence is weak and often misrepresented. A single 2009 rugby study found creatine increased DHT (a hair-loss-associated hormone) by 56%. However, no study has directly shown increased hair loss or balding from creatine. DHT elevation was temporary and within normal physiological ranges. If you're genetically predisposed to male pattern baldness, the risk is theoretical but not proven.
Loading (20g/day for 5–7 days, then 3–5g/day maintenance) saturates muscles faster — within 1 week vs. 4 weeks without loading. Both approaches reach the same endpoint; loading just gets there faster. If you need performance gains immediately, load. If you're not in a hurry, start at 3–5g/day and save yourself the expense.
No — this is one of the most persistent myths in nutrition science. Dozens of long-term studies (up to 5 years) show zero kidney damage in healthy individuals. Creatine does raise serum creatinine (a kidney marker), which may cause concern on blood tests, but this is a metabolic byproduct, not kidney damage. People with pre-existing kidney disease should consult their doctor.
Timing matters less than consistency. Post-workout with carbohydrates slightly improves uptake (insulin drives creatine into muscle cells), but the difference is small. The most important thing is taking 3–5g every day — including rest days — to maintain saturation. Missing one day is not critical, but missing weeks will deplete stores.
Creatine draws water into muscle cells (intracellular), not into the gut or subcutaneous tissue. True bloating is rare. The 1–3kg weight gain during loading is water in muscles — this is the desired effect, not bloating. If you experience genuine gut bloating, try micronized creatine monohydrate (smaller particles, easier to dissolve) or creatine HCl.
