The ultimate bone health formula. With a unique blend of nutrients to support optimum absorption.
  • Product Information

  • Osteoguard® Ultra is our premium bone health formula, offering high levels of vitamin K at 90µg in the most bioeffective form of K2 MK-7, which is widely known to support bone health. This all-in-one bone health formula delivers valuable amounts of calcium and vitamin D3 " at 500mg and 10µg, respectively, plus 250mg of magnesium.
    What do Vitamins D3, K2, Calcium and Magnesium contribute to?

    - Vitamin D3 contributes to the maintenance of normal absorption and utilisation of calcium and phosphorus and normal bones, teeth, and muscle function. It also contributes to the reduction in the risk of osteoporotic bone fracture.* Find out more about vitamin D here.

    - Vitamin K2 contributes to the maintenance of normal bones and blood coagulation. Find out more about vitamin K here.

    - Calcium contributes to the maintenance of normal bones, teeth and muscle function. This mineral also contributes to the reduction in the risk of osteoporotic bone fracture.* Find out more about calcium here.

    - Magnesium contributes to the maintenance of normal bone, teeth and muscle function. Find out more about magnesium here.

    *A beneficial effect is obtained with a daily intake of 20µg Vitamin D3 and 1200mg Calcium. Taking two tablets daily provides 10µg Vitamin D3 and 500mg Calcium, which goes a long way towards achieving these levels.

    This carefully curated formula is our Nutrition Experts top choice for women aged 50 years and older since calcium and vitamin D help to reduce the loss of bone minerals in post-menopausal women. Low bone mineral density is a risk factor for osteoporotic bone fractures. Visit our Menopause Hub here.

    Vitamin D helps to reduce the risk of falling associated with postural instability and muscle weakness. Falling is a risk factor for bone fractures among men and women 60 years of age and older. Vitamin K2 (menaquinone) exists in two forms: synthetic MK-4 and natural MK-7. Studies suggest natural MK-7 is far more bioavailable (readily absorbed) than synthetic MK-4. Derived from chickpea protein, not soya (for people who need to avoid soya), our formula contains pure, natural, full-spectrum MK-7.

    The body obtains vitamin K as vitamin K1 (phylloquinone), found in green leafy vegetables, and vitamin K2 (menaquinone), which is naturally produced by the live bacteria in our digestive tract and present in some fermented foods. The body absorbs vitamin K2 better than K1. But since modern diets generally don’t provide enough, supplementation is often recommended.

    We've ensured the strength and bioavailability of Osteoguard® Ultra. The inclusion of calcium as citrate/carbonate and magnesium as citrate, hydroxide and carbonate makes this broad-spectrum formula body-ready and highly absorbable.

    We've chosen to supply Osteoguard® Ultra in tablets, not capsules, since this material can accommodate highly concentrated amounts of vitamin D3, vitamin K2, magnesium, and calcium.

Am on medication that can affect my bone health so was prescribed calcium with vitamin D. My doctor mentioned that the ********** one is not the best. I did some research and found this one. Since taking it I have found my nails are stronger, grow quicker with less breakage. Given the visible improvement in my nails I am convinced that my bones are benefitting. Natures Best products are in my opinion great quality and value. Thank you NB!
