Creatine for Postmenopausal Women: What the Meta-Analysis Really Shows (Strength, Lean Mass, Safety) Alex and Antonella discuss a systematic review and meta-analysis on creatine monohydrate in postmenopausal women, explaining what creatine is, how it supports cellular energy (ATP), and why meta-analyses help clarify effects in specific populations rather than extrapolating from younger men. The analysis found clear, significant benefits for lean body mass and muscle strength, but only when combined with resistance training; without resistance training, creatine showed no added benefit. They review dosing differences across studies and note that 5 g/day appeared to be the most effective threshold compared with 1–3 g/day, influencing clinical recommendations. They also cover safety, common digestive side effects (bloating/diarrhea), optional loading approaches, possible water-weight gain from muscle hydration, and the potential for creatine to raise blood creatinine labs without indicating kidney damage. 00:00 Introductions 00:06 Why Creatine Today 01:07 Creatine Basics Explained 02:33 Dietary Sources 03:16 What Meta Analysis Means 07:33 Study Outcomes Overview 08:56 Exercise Is Required 11:30 How Creatine Helps Muscles 12:42 Best Dose For Women 15:58 Safety And Side Effects 20:01 Weight Gain And Water 22:26 Creatinine Lab Confusion 24:31 Key Takeaways And Goodbye Creatine monohydrate for lean mass, strength, and bone density in postmenopausal women: a systematic review and meta-analysis - https://doi.org/10.1080/15502783.2026...
