Vitamin K1

What Is Vitamin K1?

Vitamin K1, also known as phylloquinone, is a fat-soluble vitamin best recognized for its essential role in healthy blood clotting and vascular function. Naturally found in leafy greens like spinach, kale, and broccoli, Vitamin K1 is also a valued ingredient in wellness and skincare supplements due to its broad benefits for skin clarity, capillary strength, and tissue recovery. Although widely available in food, factors like poor fat absorption, restrictive diets, or certain medications can reduce bioavailability—making supplementation a useful option for many individuals. The most well-known function of Vitamin K1 is supporting normal blood clotting. It activates specific proteins that allow the blood to clot efficiently, preventing excessive bleeding and promoting proper wound healing. This makes it especially important in recovery-focused supplements and topical applications designed to reduce bruising, minimize redness, and help calm irritated or reactive skin.

In skincare, Vitamin K1 is often included in formulations to strengthen capillaries and promote an even, balanced complexion. Its ability to reduce the appearance of blotchiness, spider veins, and post-procedure bruising makes it a go-to for calming sensitive or post-treatment skin. By helping improve microcirculation and vessel integrity, Vitamin K1 enhances skin resilience and tone—supporting a visibly clearer and more uniform look over time. Beyond the skin, Vitamin K1 also contributes to calcium regulation in the body. It activates proteins that help direct calcium to the bones where it's needed and away from soft tissues like arteries, where excess calcium can contribute to stiffness or plaque buildup. When combined with Vitamin D3, collagen, or magnesium, Vitamin K1 supports both bone strength and tissue elasticity, offering benefits that extend to skin firmness, joint flexibility, and healthy aging.

Vitamin K1 also has anti-inflammatory properties, which further support tissue repair and immune health. By helping to regulate the body’s response to oxidative stress, Vitamin K1 contributes to the healing process after injuries, surgery, or environmental stressors such as pollution or UV exposure. This makes it a smart choice not only for beauty supplements, but also for products designed to support active lifestyles or recovery regimens. While Vitamin K1 is abundant in green vegetables, its absorption is fat-dependent. People on low-fat diets, those taking cholesterol-lowering drugs, or individuals with digestive conditions that impact fat absorption may not be getting enough. In these cases, supplementing with a high-quality, bioavailable form of Vitamin K1 ensures more consistent support for both internal and external systems.
