Leg swelling (chronic venous insufficiency)
+3 (Strong Evidence)
- Pycnogenol improves swelling in the lower legs, whether due to simple inactivity, incompetent blood vessels, or prolonged sitting during car or airline travel.
- Improvements are seen as soon as 2 weeks after starting treatment. Maximal benefit is seen by the 8th week of use.
- In a trial comparing pycnogenol with compression stockings, the supplement worked better. The best results were obtained by using both methods together.
- The studies of this product were quite small. Larger, better designed trials need to be performed to see if the results hold up.
- All the studies reviewed were performed by the same research group, and the maker of pycnogenol provided free supplies of the product. At least the study itself was not funded by the manufacturer.
- Pycnogenol is expensive, and it will not likely be covered by insurance.

DOSAGE:Take 150 mg once or twice a day.
CONCLUSION:We conclude that pycnogenol is a safe and effective product for the treatment of leg swelling caused by chronic venous insufficiency. This product is expensive, but you’ll know if it’s worth it within a few weeks because the swelling should be noticeably better. If you elect to try it, remember to include it in your list of medications when you visit your doctor and other health care providers.
