"The
U.S. is not doing what it should to get fruits and vegetable in its diet," said
Dr. J. Michael Gaziano, who is a heart researcher at Harvard Medical School.
"People should consume five to seven servings of fruits and vegetables
every day," according to Dr. Folts. "For those who cannot and will not
do this, a flavonoid supplement ... may be useful." |

There
are a lot of commercial flavonoid supplements on the market today that claim
cardiovascular protection. Plant extracts containing flavonoids are not all
bioavailable, the body is unable to take them in and use them. Some of the
companies have tried to prove their claimed protection by in vitro (test tube)
testing. When these products were tested in vivo (in living humans or
animals) it proved that many of the claims were completely false or exaggerated. |

Dr.
Folts has found only one supplement that shows significant benefits. The
supplement that showed benefits was tested on 14 people who took the supplement over a
seven-day period. The supplement contains grape seed extract; grape skins,
Ginkgo biloba, bilberries and a flavonoid called quercetin. |
