The Short Answer
Vitamin K1 from spinach is a natural nutrient that helps your blood clot properly and supports strong bones by helping calcium bind to your skeleton.
CategoryVitamin & Mineral
GroupVitamin
Evidence LevelModerate
Synergy Pairings4
Health Benefits
Regulates blood coagulation by activating specific clotting factors, ensuring proper hemostasis and wound healing.
Enhances bone mineralization by facilitating the carboxylation of osteocalcin, which binds calcium to the bone matrix.
Supports cardiovascular health by activating matrix Gla-protein (MGP), which inhibits arterial calcification and maintains vascular elasticity.
Provides antioxidant protection, reducing oxidative damage and supporting overall cellular health.
Contributes to skin health by supporting tissue repair and potentially reducing the appearance of vascular discoloration.
Origin & History
Vitamin K1, or phylloquinone, is a fat-soluble nutrient predominantly found in leafy green vegetables like spinach (Spinacia oleracea). This essential compound is primarily involved in activating proteins necessary for blood coagulation and calcium metabolism. It is crucial for maintaining vascular integrity, supporting skeletal strength, and offering cellular protection, making it a key component in functional nutrition.
“Spinach, the primary source of Vitamin K1, has been cultivated for millennia, originating in ancient Persia and spreading globally. Revered in traditional diets for its vitality-enhancing properties, its natural richness in phylloquinone has made it a keystone nutrient in modern nutritional strategies for supporting cardiovascular, skeletal, and cellular health.”Traditional Medicine
Scientific Research
Clinical research supports Vitamin K1’s role in increasing bone mineral density and reducing fracture risk. Studies also indicate its capacity to prevent arterial stiffening and lower cardiovascular risk through matrix Gla-protein activation. Additional research confirms its antioxidant potential in reducing oxidative stress markers.
Preparation & Dosage
Dietary Intake
Best obtained from leafy green vegetables like spinach, kale, and broccoli; consume with a source of fat for optimal absorption.
Supplements
90-120 mcg for adults
Available in capsules, tablets, or liquid drops, often combined with Vitamin D3. Typical daily dosages range from .
Topical Application
Incorporated into skincare formulations to support skin tone, reduce redness, and aid in bruise healing.
Contraindications
Individuals on anticoagulant medications (e.g., warfarin) must monitor intake carefully due to potential interactions.
Nutritional Profile

Frequently Asked Questions
What is Vitamin K1 from spinach?
Vitamin K1 (phylloquinone) is a fat-soluble vitamin naturally abundant in spinach and other dark leafy greens. It is essential for activating blood clotting factors and supporting bone mineralization through the carboxylation of osteocalcin. One cup of cooked spinach provides over 800 mcg, far exceeding the daily adequate intake.
How can I improve Vitamin K1 absorption from spinach?
Vitamin K1 from raw spinach is poorly absorbed (only about 5-10%) because it is tightly bound within plant cell membranes. Cooking spinach and consuming it with a source of dietary fat such as olive oil or butter can increase absorption by 2-3 times. Supplemental K1 in oil-based capsules offers even higher bioavailability.
Is Vitamin K1 from spinach better than K2 for bone health?
While K1 supports bone health, Vitamin K2 (particularly MK-7) is generally considered more effective for bone mineralization and cardiovascular protection due to its longer half-life and greater ability to activate osteocalcin and matrix Gla-protein. For comprehensive bone support, many experts recommend combining K1-rich foods like spinach with K2 supplementation.
