Calcium

Our Calcium section has two contrasting products: OstroVit Vitamin D3 + K2 + Calcium, a 90-tablet combination with calcium carbonate, and Trace Minerals Liquid Ionic Calcium, a 59ml vegan concentrate you add to drinks. Both suit adults whose diet is light on dairy, fortified foods or other calcium sources.

Tablet or liquid?

  • OstroVit Vitamin D3 + K2 + Calcium: calcium carbonate with vitamins D3 and K2 in 90 tablets. Calcium and vitamin D contribute to the maintenance of normal bones, vitamin D contributes to the normal absorption and utilisation of calcium, and vitamin K contributes to the maintenance of normal bones. Take it with a meal.
  • Trace Minerals Liquid Ionic Calcium: the label serving is 1.25ml (a quarter teaspoon, about 25 drops) daily in food or juice, which hides the strong mineral taste. The ingredients are purified water and citric acid, and it is labelled vegan. Shake well and do not refrigerate.

How much calcium you need

The NHS says adults need 700mg of calcium a day, and most people can get this from food such as dairy, fortified plant drinks, tofu set with calcium, and bread made with fortified flour. Taking 1,500mg or less a day from supplements is unlikely to cause harm. Count the calcium in any multivitamin or Cal/Mag/Zinc liquid you already take.

Getting the most from calcium

  • Calcium carbonate is best taken with food.
  • Take calcium and iron supplements at different times, because calcium can reduce iron absorption.
  • Calcium contributes to normal muscle function as well as normal bones and teeth.

Calcium: your questions answered

How much calcium do adults need?

The NHS says adults need 700mg a day, which most people can get from a varied diet. Taking 1,500mg or less a day from supplements is unlikely to cause harm.

Why is vitamin D added to calcium supplements?

Vitamin D contributes to the normal absorption and utilisation of calcium, so the two are often combined. OstroVit also adds vitamin K, which contributes to the maintenance of normal bones.

Is Trace Minerals Liquid Ionic Calcium vegan?

Yes, it is labelled vegan and contains purified water and citric acid. Take 1.25ml daily in food or juice, as the label directs.

Can I take calcium with iron?

Take them at different times of day, because calcium can reduce how much iron your body absorbs. A morning and evening split works well.

Is the OstroVit tablet suitable for vegans?

Check the label. Vitamin D3 is often made from lanolin from sheep's wool, so D3 products are not automatically vegan.
