Some research suggests that red clover may help improve the heart health of postmenopausal women. Scientists think the isoflavones in red clover are the active ingredient responsible for this effect.
A 2006 review of studies by the University of Illinois in Chicago reported that red clover extract can decrease the amount of a type of fat in the blood called triglycerides, while increasing levels of ‘good’ HDL cholesterol.
A meta-analysis of studies in postmenopausal women taking red clover for 4-12 months improved their heart health. This was due to a significant increase in the ‘good’ cholesterol HDL and a decrease in total and ‘bad’ cholesterol (LDL) levels.13
Another 2015 study on 147 postmenopausal women found that taking 50mg of red clover (Rimostil) daily for 1 year decreased ‘bad’ LDL cholesterol by 12%.14
Therefore, despite some optimistic results, authors of the studies agreed that more large, high-quality studies are needed.
Also, it’s worth noting that these studies involved solely older, menopausal women, so it’s not known if these effects would be the same in the general population.
However, even though the results appear positive, more research is necessary.
