Beetroot boost: simple juice may supercharge workouts for women after menopause
NCT ID NCT07572877
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether drinking beetroot juice before exercise helps post-menopausal women get more health benefits from their workouts. Beetroot juice is rich in nitrates, which the body turns into nitric oxide to improve blood flow. The researchers will measure changes in heart fitness, muscle strength, body fat, and overall physical function in 60 inactive women aged 50-70.
