Pycnogenol® May Prevent Leg Swelling, Blood Clots When Sitting on Long Flights
Sitting anywhere-in a car, at the office-for long periods can cause body fluids to accumulate, swelling the legs, ankles, and feet, and raising chances for blood clots. Long flights in cramped seating magnifies the problem.
This study followed 295 economy-class air travelers flying twice a week for more than eight hours. Doctors divided the group into low, moderate, or high likelihood of deep-vein blood clots, with this last group taking a daily aspirin. Participants in each group took a placebo; 150 mg of Pycnogenol® per day beginning three days before and continuing three days after each flight; or only wore compression stockings during flight. Participants could choose to take Pycnogenol and not be compared to placebo. All participants did in-flight exercises and drank water.
Compared to placebo or stockings, swelling was lower for Pycnogenol in all three groups, and no one taking Pycnogenol had a blood clot. The Pycnogenol group also had fewer signs of jet lag.

These results should not be surprising. Pycnogenol is rich in various bioflavonoids which are well known for their beneficial effect on the peripheral circulation.
