PowerCal is a comprehensive calcium magnesium supplement combining six targeted nutrients in a single daily serving for men and women who want reliable, proactive support for bone strength, bone density, healthy teeth and gums. Rather than providing calcium in isolation, this formula brings together the full suite of co-factors that allow calcium to be properly absorbed and directed where the body needs it most.

What makes it work

Calcium 900 mg per serving from a dual source blend of Calcium Carbonate and Calcium Citrate, providing 69% of the recommended daily value in two complementary forms for thorough absorption throughout the day. Magnesium 500 mg from Magnesium Oxide and Magnesium Aspartate, delivering 119% of the daily value and supporting muscle function, nervous system health and the structural integrity of bone tissue. Vitamin D3 1000 IU as Cholecalciferol supporting calcium absorption and bone density, alongside Vitamin K2 30 mcg as Menaquinone-7 which directs calcium specifically to the bones and teeth rather than soft tissue. Together, this vitamin D3 K2 and calcium combination works significantly more effectively than calcium supplementation alone. Strontium 40 mg as Strontium Citrate, a trace mineral included for its role in supporting new bone growth and helping maintain bone mass over time. Oat Straw Herb Powder 10 mg, a traditional botanical also associated with bone mineralisation and healthy connective tissue.

Why this calcium supplement stands out

Most standard calcium tablets provide calcium carbonate on its own with little consideration for how the body actually absorbs and uses it. PowerCal addresses this by pairing calcium with the three co-factors it depends on most, Vitamin D3 for absorption, Vitamin K2 for targeted delivery and Magnesium for structural support, creating a complete multimineral supplement that works as a genuinely joined-up bone health formula.

Want to know more?

A comprehensive bone health supplement with 900 mg calcium, 500 mg magnesium, Vitamin D3 1000 IU, Vitamin K2, Strontium and Oat Straw Herb Powder in a single daily serving. Supports bone strength, bone density, teeth and gums. Kosher and Halal Certified, vegetarian friendly and gluten free.

Vitamin D3 helps the body absorb calcium efficiently from the gut, while Vitamin K2 as Menaquinone-7 ensures that calcium is directed to the bones and teeth rather than accumulating in soft tissue. This D3 and K2 combination makes calcium supplementation significantly more effective and is the reason PowerCal is a more complete bone health formula than a basic calcium tablet.

Take 4 capsules daily, ideally 2 capsules twice a day with food. Splitting the dose supports better absorption and digestive comfort. If you have a bone condition or take prescribed medication, always consult your GP before starting a new bone health supplement.
