Shatavari Supplementation in Postmenopausal Women Improves Handgrip Strength and Increases Vastus lateralis Myosin Regulatory Light Chain Phosphorylation but Does Not Alter Markers of Bone Turnover

Study answer

What this study found

Shatavari supplementation significantly improved handgrip strength while knee extensor strength showed no change. Myosin regulatory light chain phosphorylation increased, indicating potential benefits for muscle contractility. No effects on bone turnover markers were observed.

Study & population

Twenty-four postmenopausal women (≥60 years) completed a randomized, double-blind, placebo-controlled trial.

Intervention

Six-week supplementation with shatavari in postmenopausal women to assess its effects on muscle strength and markers of bone turnover.

Key limitation

Small sample size, lack of effects on knee extensor strength and bone turnover markers, and potential variability in muscle biopsy outcomes.
