Frequently Asked Questions
Does creatine monohydrate cause bloating?
Initial water retention can occur during a loading phase, but sticking to a standard 5g daily maintenance dose typically minimizes bloating while effectively saturating muscle tissue over three to four weeks.
Should I take creatine before or after workouts?
Research suggests post-workout consumption may offer slight advantages for absorption and recovery, though total daily consistency matters far more than precise timing for long-term lean muscle gains.
Is flavored creatine better than unflavored?
Unflavored creatine is generally preferred because it avoids artificial sweeteners and allows flexible stacking with other supplements, whereas flavored versions often contain additives that increase cost per serving.
Can women safely use creatine for lean muscle?
Creatine monohydrate is extensively studied and safe for women, supporting lean muscle development, strength improvements, and bone density without causing excessive bulk when combined with appropriate resistance training.
