Life Extension has determined that optimal fibrinogen levels should range between 295-369 milligrams per deciliter (mg/dL) of blood. Fibrinogen Resist™ provides targeted nutritional support for those seeking to maintain blood fibrinogen levels in healthy ranges. This formula offers a unique combination of enzymes and antioxidants that support cardiovascular health.

Each capsule of Fibrinogen Resist™ provides NSK-SD™ nattokinase, the most bioactive form of this enzyme available. Nattokinase helps to maintain healthy fibrinolytic activity and clotting function and promotes healthy circulation and blood flow. Also included is Enzogenol^®, a pine bark extract that has demonstrated antioxidant and fibrinogen-managing effects. In a study of smokers — who typically have elevated fibrinogen levels — the combination of Enzogenol^® and vitamin C significantly helped normalize fibrinogen levels.
