A new study, e-published in Phytotherapy Research, evaluates how quickly Isotonix OPC-3 is absorbed vs. the same formulation in tablet form (not commercially available).
A group of European researchers examined, over a four hour period, the ability of Isotonix OPC-3 to act as an antioxidant by measuring oxygen free radicals in the blood of human subjects.
Isotonix OPC-3 reduced plasma oxygen free radicals (working as an effective antioxidant) within 10 minutes. The OPC-3 tablet took about 1 hour to produce a similar effect. Furthermore, the investigators noted that Isotonix OPC-3 had a stronger antioxidant effect throughout the entire 4 hour period vs. OPC-3 in tablet form.
The authors concluded: “the findings demonstrate that the flavonoid mixture provided in isotonic OPC-3 is significantly more bioavailable in humans, in terms of antioxidant activity than an equivalent mixture in tablet form. “ Furthermore, the isotonic OPC-3 formulation resulted in a stronger antioxidative effect than an equivalent mixture in tablet form.
