Effect None
Trial Design Double blind
Trial Length 1-6 months
Number of Subjects 80
Gender Both Genders
Age Range 45-64, 65+
Body Types Overweight, Average
Notes for this study:
In otherwise healthy older individuals, 80mg of the red clover isoflavones over six weeks weeks was able to reduce arterial stiffness without necessarily affecting blood flow nor pressure, which was thought to be due to the formononetin content (which also decreased VCAM-1).
Funding issues for this study:
