Clavicle Error - Broken Collarbone

I tend to agree. My doctor said the same. I eat a balanced and healthy diet anyway. However even if 90% of the extra calcium, vitamins and oils aren't needed at least you know your body has a good supply of everything it needs during the 'rebuild'

A lot of people are chronically short of calcium and other minerals.

Especially cyclists and women.

If you have enough for your needs then extra will do no harm, but a lot of people can benefit from more than is their everday diet. Stresses such as broken bones, strains of weight bearing, and micro fractures from impact sports can create a greater demand for bone building minerals than in a sedentary person. And when those demands are met, it can contribute to faster recovery and stronger bones.
Sweating causes mineral loss, cyclists sweat a fair bit.

Also, like I said, Calcium & magnesium combo works as an excellent natural pain killer. If you want it to work for migraines you can also combine it with B6.The transportation of nerve impulses in the body is also dependent on this mineral. Insufficent calcium can cause muscle cramping, poor quality/strength of muscle contraction and also irritability and nervous tension.

A sedentary person may not notice these things, but someone involved in a lot of physical activity would.
