About

A Randomised, Double-blind, Placebo-controlled Clinical Trial to Evaluate the Effect of Lifenol® in Improving Bone Status in Postmenopausal Osteopenic Women. 100 postmenopausal women will be enrolled to investigate the effect of a 12 month supplementation with Lifenol® on bone density DXA parameters and plasma bone biomarkers.

Full description

Osteoporosis is a skeletal disorder characterized by reduced bone mass and deterioration in bone architecture leading to an increased bone fragility and fracture risk. Postmenopausal women are a particularly at-risk population as the maintenance of bone homeostasis is influenced by estrogens. Recently, phytoestrogens have drawn attention as an interesting natural way to prevent oestrogen-deficient osteoporosis. Hops contain one of the most potent phytoestrogen known to date: 8-prenylnaringenin (8-PN). Lifenol® is a polyphenolic powdered extract obtained by a patented process from the female hop flowers (Humulus lupulus L.), standardized in 8-PN content.

Therefore, the present clinical trial aims to determine whether long-term consumption of Lifenol® can reduce bone mineral density loss in postmenopausal women with osteopenia taking traditional recommended calcium and vitamin D supplementation (1000 mg of calcium and 800 IU of vitamin D per day).

100 postmenopausal women (>1 year post-menopause) will be enrolled to consume during 12 months either Lifenol® (dose of 100µg of 8-PN per day) or a placebo. Effect of investigational product will be measured notably on bone density DXA parameters and plasma bone biomarkers.
