Vitamin K

Possible Benefits

The health benefits of Vitamin K are diverse, ranging from cardiovascular support to optimal bone metabolism:

• Helps support Bones & Joints by facilitating osteocalcin activation and bone mineralization.
• Supports Heart Health by preventing vascular calcification and maintaining arterial flexibility.
• Contributes to Bladder Health indirectly by supporting healthy circulation and reducing risk of clot-related issues.
• May aid in General Health by balancing calcium homeostasis and supporting coagulation pathways.

Side Effects

Vitamin K supports blood clotting and bone health, but high doses may cause mild effects. Keep an eye out for:

• Possible gastrointestinal upset, nausea or cramps
• Occasional jaundice or yellowing of skin at very high doses
• Temporary mild hypercoagulability, increased clotting tendency
• Rare allergic rash or itching
• Occasional headache or dizziness

Interactions

Possible interactions include:

• Vitamin D and K therapies: K is critical for clotting; when used with D3, monitor coagulation if on warfarin.
• Mineral supplements: K can interact with calcium and magnesium; balance doses to avoid mineral imbalances.

Precautions

Before starting Vitamin K, confirm none of the following apply to you. If they do, consult your healthcare provider:

• Individuals on anticoagulant therapy (e.g., warfarin): Vitamin K counteracts effects; avoid without monitoring INR
• People with clotting disorders: May exacerbate hypercoagulability; use under supervision
• Those with liver disease: Impaired metabolism may alter activity; monitor function
• Pregnant or breastfeeding women: Generally safe at dietary levels; avoid high-dose supplementation
• Patients scheduled for surgery: Discontinue high-dose use at least two weeks prior, potential interactions with anesthesia and clotting
