Windmill Natural Vitamins Vitamin K-2 with D-3, 60 Tablets

Health Benefits of Vitamin K-2 with D-3

Discover Windmill Natural Vitamins — This powerful combination of vitamin K-2 (as MK-7) and vitamin D-3 works together to help keep your bones strong and your heart healthy. Vitamin D-3 boosts calcium absorption from your diet, while vitamin K-2 directs that calcium to the right places – your bones and teeth – and away from soft tissues like arteries. Together, they support:

• Cardiovascular health: By activating matrix Gla protein, which helps prevent calcium build-up in blood vessels.
• Bone strength: By activating osteocalcin, which anchors calcium into the bone matrix.
• Healthy teeth: Calcium directed to teeth supports dentin formation.
• Immune function: Vitamin D-3 is well known for its role in immune defence.

Windmill’s formula provides these nutrients in a simple tablet, free from artificial colors, flavours and preservatives.

What Is Vitamin K-2 (Menaquinone-7)?

Vitamin K-2, particularly the menaquinone-7 (MK-7) form, is a fat-soluble vitamin that plays a vital role in calcium metabolism. It helps direct calcium to your bones and teeth while preventing it from depositing in soft tissues like arteries. This makes it essential for maintaining strong bones and a healthy cardiovascular system. Unlike vitamin K-1 (phylloquinone), which mainly supports blood clotting, K-2 has a longer half-life and is more effective at activating proteins that regulate calcium. Each Windmill tablet delivers 100 mcg of MK-7 alongside 25 mcg (1000 IU) of vitamin D-3 to enhance absorption and synergy.

Vitamin K-2 vs. Vitamin K-1: What’s the Difference?

Although both forms of vitamin K are important, they serve different roles. Vitamin K-1 is found in green leafy vegetables and is mainly used by the liver to activate clotting factors. Vitamin K-2 is produced by gut bacteria and can also be found in fermented foods like natto. It has a longer half-life in the body and is more effective at activating proteins outside the liver, such as osteocalcin (for bone mineralisation) and matrix Gla protein (for arterial health). For bone and cardiovascular support, K-2 – especially MK-7 – is often the preferred choice in supplements.

Recommended Dosage and Usage

The recommended adult dose is one tablet daily, preferably with a meal containing fat to improve absorption. Since vitamin K-2 is fat-soluble, taking it with food ensures optimal uptake. Do not exceed the recommended dose unless advised by a healthcare professional. Individuals taking anticoagulant medications (e.g., warfarin) should consult their doctor before using vitamin K supplements. Always read the label and follow directions for use.

What to Look for in a Quality Supplement

When selecting a vitamin K-2 supplement, consider the form (MK-7 is preferred for sustained activity), dosage, and purity. Windmill’s product is Non-GM, gluten free, and produced in cGMP-compliant facilities in the USA. It contains no artificial colors, flavours, or preservatives. The added vitamin D-3 enhances calcium metabolism. With over 50 years of trust, Windmill offers a reliable choice for those supporting their bone and cardiovascular health.

Potential Side Effects and Interactions

Vitamin K-2 is generally well tolerated. However, high doses may cause mild digestive discomfort or interact with anticoagulant medications. Vitamin K can interfere with the action of blood thinners, so medical supervision is essential. Pregnant or breastfeeding women should also consult a healthcare professional. Always stick to the recommended dose and discuss with a qualified health practitioner.
