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

Health Benefits of Vitamin K-2 with D-3

The combination of vitamin K-2 and vitamin D-3 works synergistically to support your body's natural processes. Vitamin D-3 enhances calcium absorption from the gut, while vitamin K-2 directs that calcium to the bones and teeth. This teamwork helps contribute to normal bone maintenance, healthy teeth, and normal immune function. Windmill’s formula provides these nutrients in a convenient tablet form, free from artificial colours, flavours, and preservatives.

• Support bone strength: By activating osteocalcin, which binds calcium to the bone matrix.
• Promote cardiovascular health: By inhibiting calcium deposition in arteries through matrix Gla protein activation.
• Maintain healthy teeth: Calcium delivery supports dentin formation.
• Support immune function: Vitamin D-3 is known for its role in immune regulation.

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

Vitamin K-2, specifically the menaquinone-7 (MK-7) form, is a fat-soluble vitamin that plays a crucial role in directing calcium to the bones and teeth while preventing its deposition in soft tissues like arteries. This makes it an essential nutrient for maintaining strong bones and a healthy cardiovascular system. Unlike vitamin K-1 (phylloquinone), which is primarily involved in blood clotting, K-2 has a longer half-life and is more effective at activating proteins that regulate calcium metabolism. Windmill’s Vitamin K-2 supplement provides 100 mcg of MK-7 per tablet, combined with 25 mcg (1000 IU) of vitamin D-3 to enhance absorption and synergy.

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

While both forms of vitamin K are important, they serve distinct functions in the body. Vitamin K-1 is found in green leafy vegetables and is primarily used by the liver to activate clotting factors. Vitamin K-2, on the other hand, is produced by gut bacteria and found in fermented foods like natto. It has a longer circulating half-life and is more effective at activating extra-hepatic proteins, such as osteocalcin (for bone mineralisation) and matrix Gla protein (for arterial health). When choosing a supplement, K-2 (especially MK-7) is often preferred for bone and cardiovascular support.

Recommended Dosage and Usage

Each tablet provides 100 mcg of vitamin K-2 (as MK-7) and 25 mcg (1000 IU) of vitamin D-3. The recommended dosage for adults is one tablet daily, preferably with a meal containing fat to enhance absorption. Since vitamin K-2 is fat-soluble, taking it with food ensures optimal bioavailability. Do not exceed the recommended dose unless directed by a health care professional. Individuals taking blood-thinning medications (e.g., warfarin) should consult their doctor before using vitamin K supplements.

What to Look for in a Quality Supplement

When choosing a vitamin K-2 supplement, consider the form (MK-7 is preferred for sustained activity), dosage, and purity. Windmill’s product is non-GMO, Gluten-free, and manufactured in cGMP-compliant facilities in the USA. It contains no artificial colours, flavours, or preservatives. The inclusion of vitamin D-3 adds value by supporting calcium metabolism. With over 50 years of trust, Windmill offers a reliable option for those seeking bone and cardiovascular support.

Potential Side Effects and Interactions

Vitamin K-2 is generally well tolerated. However, high doses may cause mild digestive upset or interact with anticoagulant medications. Vitamin K can interfere with the action of blood thinners, so medical supervision is essential. Pregnant or nursing women should also consult a health care provider. As with any supplement, it is important to adhere to recommended dosages and discuss with a qualified health professional.
