Windmill Natural Vitamins Vitamin K (K-2 Menaquinone-7, 100mcg) with Vitamin D3 1000 IU, 60 Tablets (Pack of 2)

Understanding Vitamin K2 (Menaquinone-7) and Vitamin D3

Vitamin K2 exists in several forms, but menaquinone-7 (MK-7) is one of the most studied for its bioavailability and sustained activity. MK-7 is derived from natto (fermented soy beans) and supports the activation of proteins that help direct calcium to your bones and teeth rather than soft tissues. Vitamin D3, or cholecalciferol, is the form naturally produced by your skin when exposed to sunlight. It enhances calcium absorption in the gut and works synergistically with vitamin K2 to maintain bone density and arterial health.

Key Benefits of This K2 and D3 Combination

• Supports calcium absorption: Vitamin D3 helps your body absorb calcium from food, while vitamin K2 helps direct that calcium to your bones for proper mineralisation.
• Promotes bone strength: Adequate intake of both vitamins contributes to maintaining healthy bone density as you age.
• Cardiovascular support: By activating matrix Gla-protein (MGP), vitamin K2 helps keep calcium from depositing in artery walls, supporting heart health.
• Convenient dosing: Each tablet provides 100 mcg MK-7 and 1000 IU D3 — a balanced combination for daily maintenance.

Who May Benefit from This Supplement?

Individuals with limited sun exposure, older adults, those following a vegetarian or vegan diet (note: D3 from lanolin, K2 from natto), and anyone seeking to support bone density and cardiovascular function may find this combination valuable. If you take calcium supplements, pairing them with K2 and D3 helps ensure proper utilisation. Always consult your healthcare provider before starting any new supplement, especially if you take blood-thinning medications (e.g., warfarin) due to potential interactions with vitamin K.

How to Incorporate This Supplement into Your Routine

Take one tablet daily, preferably with a meal containing fat to enhance absorption of these fat-soluble vitamins. Each bottle contains 60 tablets (a two-month supply), and this pack includes two bottles for a four-month supply. Store in a cool, dry place away from direct sunlight. As with any supplement, consistency is key to experiencing the full benefits.

Frequently Asked Questions

Can I take this supplement if I am on blood thinners? If you take anticoagulant medications, consult your doctor before using vitamin K supplements, as vitamin K can interfere with their effectiveness.

Is this product suitable for vegetarians? The vitamin D3 is derived from lanolin (sheep's wool), making it suitable for lacto-ovo vegetarians but not for strict vegans. The vitamin K2 (MK-7) from natto is plant-based.

How does this compare to vitamin K1? Vitamin K1 is primarily involved in blood clotting, while K2 (especially MK-7) plays a more significant role in bone and cardiovascular health.
