  • Product Information

  • OsteoGuard Ultra: Our advanced bone health supplements with all the key nutrients needed for maintaining bone density and strength and healthy teeth. Our recommendation for adults over 50 and individuals engaged in high-impact activities.

    Key benefits:
    • Vitamin D3: Essential for the absorption and utilisation of calcium and phosphorus, vitamin D3 supports normal bones and teeth. It also plays a crucial role in reducing the risk of osteoporotic fractures. Vitamin D3 is also helpful as it supports muscle function – essential in reducing the risk of falls associated with postural instability and muscle weakness.
    • Vitamin K2 (MK-7): Known for its superior bioavailability, vitamin K2 contributes to maintaining normal bones and blood coagulation (important for heart health).
    • Calcium: A vital mineral for maintaining strong bones and teeth, calcium is included in our formula in the forms of citrate and carbonate for optimal absorption.
    • Magnesium: This mineral supports normal muscle function and bone health, provided in highly bioavailable forms, citrate, hydroxide and carbonate that are easily absorbed by the body.

    Who is OsteoGuard Ultra for? OsteoGuard Ultra is beneficial for adults over 50 but particularly women aged 50 and older, as it helps reduce bone loss after menopause. It's also ideal for individuals engaged in high-impact activities, vegans, or those who are lactose intolerant, as our formula is free from soya and lactose. We would also recommend this product for those concerned about bone health after a DEXA scan or a history of low nutrient intake.

    Inspired by nature, perfected by science: We are committed to harnessing the power of nature and elevating it through scientific innovation. That’s why our OsteoGuard Ultra tablets exclusively feature vitamin K2 (MK-7) derived from chickpeas, ensuring superior bioavailability and making it an ideal choice for those who need to avoid soy. By combining natural ingredients with cutting-edge research, we provide a supplement that is both highly effective and gentle on your body.
