What’s Inside (and Why It Matters)

Vitamin K2 (as K2VITAL™ Menaquinone-7) – 200mcg

Vitamin K2 plays a crucial role in calcium metabolism, helping to direct calcium away from the arteries and into bones where it belongs. In its MK-7 form (menaquinone-7), K2 is especially bioavailable and long-lasting in the body.

Scientific Support

A 2007 study published in the Journal of Nutrition found that K2 intake was inversely associated with arterial calcification and coronary heart disease in healthy populations.

A 2015 review in Thrombosis and Haemostasis highlighted K2’s role in activating Matrix Gla Protein (MGP), an inhibitor of arterial calcification.*

Citrus Bergamot Extract (Citrus bergamia) – 2,000mg

Citrus Bergamot is a polyphenol-rich fruit native to Calabria, Italy, known for its cardiovascular and metabolic benefits. Its flavonoids, such as neoeriocitrin and naringin, have shown promise in supporting healthy lipid metabolism and endothelial function.*

Scientific Support

A 2011 study in Fitoterapia found that 500mg of bergamot extract daily reduced total cholesterol, LDL, and triglycerides while increasing HDL.

A 2022 meta-analysis in Phytomedicine confirmed that Citrus Bergamot supplementation supports healthy cholesterol ratios and may reduce oxidative stress in the vascular system.*

Nattiase® Nattokinase (10,800 FU) – 540mg

Nattokinase is a fibrinolytic enzyme extracted from natto, a traditional Japanese fermented soybean dish. It supports healthy circulation by promoting the natural breakdown of fibrin, a protein involved in blood clot formation.*


Nattiase® is a patented, clinically studied form of nattokinase with consistent enzyme activity and bioavailability.

Why 10,800 FU?

A 2023 randomized controlled trial published in Nutrients found that 10,800 FU of nattokinase daily was the optimal dose for reducing fibrinogen levels, improving blood flow, and lowering markers of clot risk without affecting safety markers.* This dose outperformed both lower and higher dosages in terms of effectiveness and tolerability.

Additional Scientific Support

A 2008 study in Nutrition Research demonstrated that nattokinase supplementation reduced blood pressure in hypertensive patients over 8 weeks.

A 2015 paper in Scientific Reports suggested nattokinase may help reduce blood viscosity and support healthy endothelial function by breaking down excess fibrin.*
