Fibrinogen activity measures the amount of fibrinogen in the blood. Fibrinogen is a protein produced in the liver that is essential for the formation of blood clots. (source)
As both a coagulation factor and an acute-phase reactant, fibrinogen serves dual roles in hemostasis and inflammation. Elevated fibrinogen increases blood viscosity and promotes clot formation, while also reflecting the body's systemic inflammatory state, making it a key indicator of cardiovascular and recovery readiness. (source)
Low fibrinogen activity levels may stem from physiological factors affecting liver function, as the liver produces fibrinogen, an essential blood clotting protein. Nutritionally, deficiencies in key nutrients like vitamin K, which is involved in blood clotting, can also contribute to reduced fibrinogen activity. (source, source)
Potential Performance Impact:
Prioritize high-quality protein: Protein consumption has been shown to increase fibrinogen synthesis. (source) Dietary protein intake increases the amount of amino acids that are available for fibrinogen synthesis by the liver. (source)
Protocol: Eat 0.8 to 1.0 g of protein per pound of body weight per day. One serving examples: Eggs (3 large eggs), Chicken Breast (3.5 oz), Beef (lean cuts) (3.5 oz), Salmon (3 oz), Pork (lean cuts) (3.5 oz), Tofu (3.5 oz)
Active recovery: Fibrinogen levels are inversely correlated to levels of physical activity. (source) Exercise stimulates the release of a compound that breaks down fibrinogen. Allowing the body time to recover between periods of intense physical activity will aid in maintaining fibrinogen concentrations. (source, source)
Protocol: Prioritize techniques to enhance recovery capacity, such as low-intensity movement and mobility, at least twice a week.
Supplement with a quality protein source: Protein ingestion has been shown to stimulate fibrinogen synthesis. (source) Dietary protein intake increases the amount of amino acids that are available for fibrinogen synthesis by the liver. (source)
Protocol: Supplement with 20 to 40 g of quality protein with a goal of consuming 0.8 to 1.2 g of protein per pound of body weight per day.
High fibrinogen activity levels can be influenced by physiological factors related to the liver and inflammation, as fibrinogen is primarily produced in the liver and elevated in response to inflammation. From a nutritional perspective, diets high in saturated fats and processed foods can contribute to increased fibrinogen activity levels. (source, source)
Potential Performance Impact:
Prioritize fatty fish: Blood omega-3 fatty acid levels have been shown to blunt fibrinogen concentrations. (source) Omega-3 fatty acids decrease fibrinogen levels by inhibiting platelet aggregation and thrombin generation. (source)
Protocol: Eat at least two servings of fatty fish a week. One serving examples: Salmon (3 oz), Herring (3 oz), Bluefin Tuna (3 oz), Anchovies (3 oz), Mackerel (3 oz)
Train regularly: Regular exercise has been shown to reduce fibrinogen levels. (source) Exercise stimulates the release of a compound that breaks down fibrinogen, thereby reducing fibrinogen levels in the blood. (source, source, source)
Protocol: Follow a structured training program that exerts your body through multiple resistance and aerobic intensities. This includes a structured aerobic program that ensures at least 150 minutes of moderate intensity (50 to 70% max heart rate) or 75 minutes of high intensity (75% max heart rate or greater) a week and a structured resistance training program with moderate to heavy loads at least twice a week for resistance training. The final set of each resistance training exercise should be taken within two repetitions of failure.
Supplement with omega-3 fatty acids: Blood omega-3 fatty acids levels have been shown to blunt fibrinogen concentrations. (source) Omega-3 fatty acids decrease fibrinogen levels by inhibiting platelet aggregation and thrombin generation. (source)
Protocol: Consume at least 3 g of total omega-3 fatty acids (EPA and DHA) daily.
