Stacy Sims on Creatine
14 episodes · 70 references · 2025–2026
- Sims is a strong advocate for creatine, especially for women, emphasizing benefits for brain, gut, mood, and muscle across all life stages including pregnancy - Recommends 3–5g daily of creatine monohydrate (preferably Creapure), with a gradual phase-in protocol for women starting at 1.5g - Has used creatine personally for over a decade; no recommend-against stance, though she cautions about bloating from cheap brands or high-dose loading
Consumption
- Started taking creatine ~10 years ago to rebuild muscle after surgeries and return to racing - Has used creatine on and off throughout her athletic career, but committed after experiencing depressive episodes - Initially took ~10g (two teaspoons) on bad advice, causing severe nausea for three days before adjusting down
Benefits
- Powers all fast energetics in the body — brain function, heart health, gut integrity, and muscle contraction all require creatine - RCTs show creatine reduces depression and anxiety; women on 3–5g come out of depressive episodes faster than those on SSRIs alone - Maintains intestinal mucosal lining under stress, reducing IBS symptoms and GI distress, especially important for women
Best Practices
- Standard dose is 3–5g creatine monohydrate daily; women should phase in from 1.5g week one, 3g week two, 5g week three - Full saturation takes ~3 weeks; take every day including rest days — no acute effect from single doses - Use Creapure brand; avoid cheap acid-wash versions; for severe fatigue or depression, increase to 5g twice daily (morning and evening)
Cautions
- At 3–5g daily without carbohydrate, bloating and water retention are minimal; loading protocols (20g/day) cause significant water weight and GI discomfort - Cheap acid-wash creatine monohydrate causes bloating and stomach discomfort — quality matters - Elevated creatinine on blood tests is a normal metabolite of supplementation, not a sign of kidney damage; pause supplementation before retesting
“I started taking creatine probably about 10 years ago when I was trying to build muscle back after some surgeries and also trying to come back into a racing career.”
