Assessing the Effect of Shatavari Supplementation on Bone and Skeletal Muscle Health in Healthy Postmenopausal Women

Muscle Weakness Clinical Trial

Official title:
Assessing the Effect of Shatavari Supplementation on Bone and Skeletal Muscle Health in Healthy Postmenopausal Women: A Randomised Double Blind Clinical Trial

Clinical Trial Summary

Shatavari is a plant that grows in Nepal, Sri Lanka, India and the Himalayas and its root has long been used in Ayurvedic medicine. Its traditional uses include supporting women's health, particularly during breastfeeding and during the perimenopausal period. Shatavari has been found to contain substances that have similar chemical properties to estrogen. A decrease in the amount of ovarian estrogen production causes the menopause and this reduction in circulating estrogen has widespread effects, including promoting a decrease in bone density. This increases the risk of bone fractures. Having less oestrogen is also thought to contribute to a loss of muscle strength in postmenopausal women. As shatavari may act on the body's tissues in a similar way to estrogen, shatavari supplementation may represent one way of preventing postmenopausal bone and muscle loss. This study will investigate these questions. 24 healthy postmenopausal women aged 60 years or older will be recruited. The participants will be randomly assigned to consume shatavari (1000 mg per day, equivalent to 26,500 mg per day fresh weight shatavari) or placebo (1000 mg per day magnesium stearate) for 6 weeks. Handgrip and knee extensor strength will be measured at baseline and at 6 weeks. Vastus lateralis (VL) muscle biopsy samples will be obtained at baseline and at 6 weeks and analysed for markers of muscle function and protein turnover. Plasma and serum samples will be collected via venepuncture and markers of bone turnover (P1NP, β-CTX) will be measured at baseline and at 6 weeks. Primary human osteoblasts (not obtained from these participants) will be stimulated with pooled sera from the placebo and shatavari supplementation conditions to assess markers of osteoblast (bone-building) activity.
