Researchers at the University of Wisconsin have just reported that a combination of vitamin C and E administered to human prostate cancer cell cultures kills the prostate cancer cells. The finding adds support to the hypothesis that vitamin E and selenium are of value in prostate cancer prevention, which is being investigated by the twelve-year Selenium and Vitamin E Chemoprevention Trial (SELECT) that includes over 32,000 healthy men. Adding Vitamin E Succinate or Selenium alone modestly inhibited the growth and viability of the prostate cancer cells, adding the combination of the two dramatically inhibited prostate cancer cell growth while having no effect on either growth or viability of normal cells.

Researchers from Louisiana State University, and the University of Florida recruited 42 overweight women. They gave them either Chromium Picolinate at a dosage of 1000 mcg daily or inactive placebo for 8-weeks. Those women on Chromium voluntarily consumed 25% fewer calories because they felt satiated.

Researchers at the School of Medicine and Pharmacology, University of Western Australia in Perth investigated the effects of the cholesterol lowering drug fenofibrate and Coenzyme Q10 (CoQ) on diastolic function, blood pressure (BP), and heart rate (HR) in type 2 diabetics with left ventricular diastolic dysfunction (LVDD). The scientists performed a randomized double-blinds study prescribing different combinations to 74 subjects; fenofibrate 160 mg daily, CoQ 200 mg daily, fenofibrate 160 mg plus CoQ 200 mg daily, or matching placebo for 6 months. Echocardiography (including tissue Doppler imaging) and 24-h BP and HR monitoring were performed pre- and post-intervention.

Scientists at Kobe Pharmaceutical University in Japan note it has been reported that vitamin K supplementation effectively prevents fractures and maintains bone mineral density in people treated for osteoporosis. The objectives were to evaluate the association between plasma K1 or K2 as MK-4 and MK-7 concentration and bone health or fracture in Japanese women. A total of 379 healthy women aged 30-88 years (average age of 63) were consecutively enrolled.

Isoflavones, a powerful group of nutrients found in soybeans, and to a lesser degree in chickpeas and other legumes, can improve artery function in stroke patients, a new clinical study has found. This is the first investigation into the effects of Isoflavone supplementation on the brachial artery, which is the main artery in the arm. The trial involved 50 patients taking the isoflavone supplement, and 52 on inactive placebo for comparisons sake.
