Plus, every purchase supports the non-profit Vitamin Angels, providing a year’s worth of vitamins to a child in need.
What Is Vitamin K1?
Vitamin K1, also known as phylloquinone, is a fat-soluble vitamin naturally found in green leafy vegetables like spinach, kale, and broccoli. It plays an essential role in normal blood clotting and contributes to the maintenance of normal bones by activating proteins that bind calcium to the bone matrix. While K1 is primarily utilised by the liver for coagulation, it also supports overall skeletal health. Many people turn to Vitamin K1 supplements to ensure they meet their daily needs, especially if their diet lacks sufficient greens or if they have absorption issues.
The Power of Three Forms of Vitamin K
Not all Vitamin K supplements are created equal. This formula combines three bioactive forms: Vitamin K1 (phylloquinone), K2 as MK-4 (menaquinone-4), and K2 as MK-7 (menaquinone-7 from Bacillus subtilis natto). Why three? Each form has a unique role and duration in the body. K1 is quickly utilised by the liver for clotting factors, MK-4 supports soft tissues and bone, while MK-7 is longer-acting and helps direct calcium to bones and away from arteries. This trio provides comprehensive support for both coagulation and calcium metabolism.
Health Benefits of Vitamin K
Vitamin K contributes to several key functions in the body. Here are the primary benefits supported by research:
-
Normal Bones: Vitamin K activates osteocalcin, a protein that binds calcium to the bone matrix. Adequate intake contributes to the maintenance of normal bones and may help maintain bone density as you age.
-
Normal Blood Clotting: K1 is essential for synthesising clotting factors in the liver, ensuring proper wound healing and preventing excessive bleeding.
-
Cardiovascular Health: By activating matrix Gla-protein (MGP), Vitamin K helps prevent calcium from depositing in artery walls, supporting healthy blood vessel flexibility and heart function. This is not a health claim authorised by EFSA, but emerging research is promising.
-
Antioxidant Properties: Some forms of Vitamin K act as antioxidants, protecting cells from oxidative stress.
It is important to note that Vitamin K works synergistically with Vitamin D and calcium. Many experts recommend pairing these nutrients for optimal bone and cardiovascular health.
Recommended Dosage and Usage
The adequate intake for Vitamin K in adults is 90–120 mcg per day, but many supplements provide higher amounts to support specific health goals. This product delivers a potent dose of all three forms in one convenient capsule. Typical usage is one capsule daily with a meal containing fat to enhance absorption (since Vitamin K is fat-soluble). Always follow the serving size on the label and consult your health care provider before starting any new supplement regimen.
Potential Side Effects and Interactions
Vitamin K is generally well tolerated, but high doses may cause mild stomach upset. People taking blood-thinning medications (e.g., warfarin) should be cautious: Vitamin K can interfere with anticoagulant effects, so consistent intake and medical supervision are crucial. Those with clotting disorders or liver disease should also seek professional advice. Pregnant or nursing women should consult a doctor before uses. As with any supplement, discontinue uses if adverse reactions occur.
