New Nordic Active Legs Strong - Helps relieve the symptoms related to non-complicated Chronic Venous Insufficiency (CVI) such as sensation of swelling, heaviness and tingling of the legs. Active Legs Strong uses Grape Seed extract and Maritime Pine Bark, two potent plant extracts to naturally strengthen the blood vessel walls to reduce permeability and the associated swelling of the leg. The proanthocyanidins in both extracts are also strong antioxidants, with anti-inflammatory action to further reduce CVS symptoms.
