What it is
Sarcopenia accelerates at menopause. Women can lose muscle mass and strength quickly in the transition, which lowers metabolic rate and raises injury and fracture risk.
What's causing it
Low estradiol
Supports muscle repair, satellite cell function, and recovery from training.
Low testosterone and DHEA
Directly drive muscle protein synthesis.
Inadequate protein
Most women over 40 eat well under what's needed to maintain muscle.
Anabolic resistance
Aging muscle needs a bigger protein and training stimulus to respond.
Nutrients commonly involved
What actually helps
- Resistance training 2–4x weekly with progressive overload
- Hormone restoration including testosterone where appropriate
- Protein at 1g per pound of goal body weight
- Creatine monohydrate, which is well studied and safe in women
Questions women ask about this
Why am I losing muscle in menopause even though I exercise?
Falling estradiol and testosterone reduce muscle protein synthesis and recovery, so the same workouts no longer maintain the same muscle. Higher protein intake, progressive resistance training, and hormone restoration reverse most of that gap.
