It's widely known that calcium helps build strong bones. But according to experts from Tufts University in the US, iron is another important nutrient associated with bone health. It helps produce an integral component of bone called collagen.
Experts recommend 18 mg of iron a day to improve bone mineral density. Get your daily dose through iron-rich foods, like meat, liver, legumes, fortified cereals and green, leafy vegetables. Speak to your doctor about iron supplementation if you think you're not getting enough of the mineral through your diet. Also note that iron is only effective in bone building when the recommended 800-1200 mg of calcium are consumed as well.
