Therefore , the present meta- analysis does not suggest any significant effect of pycnogenol  on BP
Results of previous clinical trials evaluating the effect of pycnogenol supplementation on  blood pressure ( BP )  are controversial .
Normalization of cardiovascular risk factors in peri-menopausal women with Pycnogenol®.
BACKGROUND The aim of the study was the evaluation of the efficacy of Pycnogenol ® in peri-menopausal women in controlling homocysteine and C-reactive protein ( CRP ) levels , borderline cardiovascular risk factors , oxidative stress ( OS ) and symptoms associated to menopausal transition ( MT ) . METHODS Pycnogenol ® , 100mg/day , was used as a supplement for 8 weeks by a group of 35 women . A comparable group of 35 women with identical cardiovascular risk factors was included as the control group . All women were instructed to participate in a best management plan of menopause . RESULTS The two groups were comparable . All women completed the eight weeks study . Only minor deviations from the best management plan were observed . At inclusion , both groups were similar in respect to risk factors . Supplementation with Pycnogenol ® decreased the slightly elevated cholesterol and triglycerides after 8 weeks ( P<0.05 ) . Also the fasting glucose levels were normalized ( P<0.05 ) . The borderline increased blood pressure was reduced to normal values at 8 weeks ( P<0.05 ) . Plasma free radicals dropped significantly by 22 % ( P<0.05 ) . Homocysteine and CRP levels decreased sharply by 43 % and 60 % , respectively ( P<0.05 ) . No significant changes of these risk factors were noted in the control group . Almost all menopausal symptoms , scored by The Menopausal Symptoms Question naire 34 , improved significantly following supplementation with Pycnogenol ® . The supplementation was well tolerated . CONCLUSIONS The supplementation with Pycnogenol ® improved the quality of life of perimenopausal women and normalized a series of cardiovascular risk factors , especially factors connected to cardiovascular events , as homocysteine and CRP
