Placebo Comparator: Beverage Dietary Supplement: Placebo Beverage

Antioxidant capacity umol TE/L(ORAC): negligible Polyphenolic Content(mcg/ml): negligible Vitamin C (mg/100ml): 0.00 Calorie Content (Kcal/250ml):40.0

250ml twice daily for 1 month (56 doses)

Active Comparator: High Polyphenol Beverage Dietary Supplement: High polyphenol beverage

Antioxidant capacity umol TE/L(ORAC): 19987 Polyphenolic Content(mcg/ml): 1445 Vitamin C (mg/100ml): 35.35 Calorie Content (Kcal/250ml):40.0

Detailed Description:

This study will assess the potential of a beverage containing plant and fruit extracts rich in polyphenolics to modulate vascular risk.

Novel risk factors for vascular disease will be assessed including non-invasive assessment of vascular function by pulse wave analysis / pulse wave velocity and laser doppler iontophoresis.
