What Is Vitamin K1?

Vitamin K1, also known as phylloquinone, is a fat-soluble vitamin that plays a vital part in normal blood clotting and bone health. It is naturally abundant in green leafy vegetables like spinach, kale, and broccoli. While most people obtain sufficient K1 from diet, supplementation can help fill gaps for those with restricted diets or certain health conditions. Swanson Vitamin K-1 provides 100 mcg of phylloquinone per tablet, a dosage aligned with the recommended dietary intake for adults in the UK. This essential nutrient supports the body's ability to produce clotting factors and maintain bone mineral density.

Health Benefits of Vitamin K1

Supports Normal Blood Clotting – Vitamin K1 is essential for the synthesis of clotting factors in the liver. Adequate intake helps ensure that minor cuts and bruises heal properly and that bleeding stops in a timely manner.

Maintains Bone Health – This vitamin activates osteocalcin, a protein that binds calcium to the bone matrix. Adequate K1 levels are associated with better bone mineral density and reduced risk of fractures.

Swanson's Vitamin K-1 supplement provides a reliable, concentrated dose of phylloquinone to help you meet your daily needs. Each easy-to-swallow tablet is made with quality ingredients and is non-GM and gluten-free.

Vitamin K1 vs K2: Key Differences

Vitamin K exists in two primary forms: K1 (phylloquinone) and K2 (menaquinone). While both are essential for blood clotting and bone health, they differ in absorption and duration of action. K1 is primarily stored in the liver and used for coagulation, whereas K2 is distributed to tissues like bones and arteries. K2 has a longer half-life and is thought to be more effective for bone health. However, K1 remains crucial for maintaining normal clotting function. Swanson Vitamin K-1 focuses on the classic form, ideal for those specifically targeting coagulation support or as a foundational nutrient.

Recommended Dosage

The adequate intake for vitamin K1 in adults is 90 mcg for women and 120 mcg for men. Swanson Vitamin K-1 provides 100 mcg per tablet, making it easy to achieve recommended levels. For general wellness, take one tablet daily with a meal containing fat to enhance absorption. Consult your health care provider for personalized dosage, especially if you take blood-thinning medications.

Potential Side Effects & Interactions

Vitamin K1 is generally safe when taken as directed. High doses may cause mild stomach upset or allergic reactions in sensitive individuals. The primary concern is interaction with anticoagulant medications like warfarin (Coumadin). If you take blood thinners, consult your doctor before supplementing with vitamin K, as it can interfere with the medication's effectiveness. Pregnant and nursing women should also seek medical advice. Always stick to recommended dosages and avoid megadoses.

Frequently Asked Questions

Can I take vitamin K1 with other supplements? Yes, it is often combined with vitamin D and calcium for bone health. However, avoid taking it with high doses of vitamin E or A, which can interfere with K absorption.

How long does it take to see benefits? Vitamin K levels in the body can be replenished within a few weeks of supplementation. Benefits for clotting are immediate, while bone health effects accumulate over months.
