Vitacost Vitamin K Complex, 180 Softgel Capsules

Health Benefits of Vitamin K1 and K2

Supports Normal Bone Maintenance: Vitamin K contributes to the maintenance of normal bones by activating osteocalcin, a protein that binds calcium to the bone matrix.
Promotes Normal Blood Clotting: Vitamin K is essential for the synthesis of clotting factors, helping your body respond appropriately to cuts and bruises.
Cardiovascular Support: Vitamin K2 may help prevent calcium buildup in arteries, supporting heart health.
Antioxidant Properties: Some studies suggest vitamin K may help protect cells from oxidative stress.

Vitamin K1 vs K2: Key Differences

While both forms are important, they function differently in the body. Vitamin K1 is primarily used by the liver to activate clotting factors, whereas K2 (menaquinone) is more involved in directing calcium to bones and teeth and away from arteries. K2 also has a longer half-life, meaning it remains active in the body for a longer period. This supplement combines both forms to cover the full spectrum of vitamin K benefits.

What Is Vitamin K1?

Vitamin K1, also known as phylloquinone, is a fat-soluble vitamin predominantly found in green leafy vegetables. Its main role is to support the production of Gla (gamma carboxyglutamic acid) proteins, which are essential for normal blood clotting and bone metabolism. This vitamin K complex from Vitacost provides 200 mcg of K1 along with 200 mcg of K2 per serving, offering a comprehensive approach to meeting your vitamin K needs.

Recommended Dosage

Each serving of one softgel capsule provides 200 mcg of K1 and 200 mcg of K2. The UK reference nutrient intake (RNI) for vitamin K in adults is approximately 1 mcg per kg body weight per day, but many experts recommend higher intakes for bone and heart health. This formulation provides a generous amount to support your wellness goals. As a fat-soluble vitamin, take it with a meal containing fat for optimal absorption.

Potential Side Effects & Interactions

Vitamin K is generally safe and well-tolerated. However, it can interfere with blood-thinning medications such as warfarin (Coumadin). If you are taking anticoagulants, consult your doctor before taking vitamin K supplements. High doses may rarely cause flushing or mild stomach upset. Always follow the recommended dosage and seek professional advice if you have any underlying conditions.
