Look for Higher ORAC!

Currently, the certified scientific testing done on liquid vitamin supplements is through the measure of antioxidant levels; thus, measuring potency. Gone are the days when Vitamin C was the best vitamin without any dispute. Grape seed Extract (OPC) has been touted to be 20 times more potent than vitamin C and 50 times more than vitamin E. Antioxidant level makes the difference.

Oxygen Radical Absorbance Capacity or ORAC sets the standard preferred by the market. This is, however, supported by mere in vitro studies on biological samples such as blood.

Measurements of some phytonutrients are determined through the elevation of the properties in the blood. Nonetheless, some experts challenge the claim of ORAC value. They say that having high nutrients when in raw form does not necessarily make-up the same nutrient-rich supplement. Thus, the elevation won’t be reflected in the blood.

Despite the lack of physiological evidences of the process' effectiveness in human subjects, sales are still going stronger especially for those offering hard-to-believe benefits. What science can't prove, man can prove, as they say. Testimonials on these wonders are all over the place, from the Internet to TV and radio commercials to your neighbor's firsthand experience.

At the top of the list of most favored sources are wild blueberry, cranberry, blackberry, wolf berry and acai fruit – all converted to be your favorite liquid vitamin supplements. Whatever is your choice, remember that a balanced diet is still the first defense against sickness. ORAC certification is futile if your diet is consistently erroneous.
