Bone Fractures

How can magnesium and vitamin D3 help protect against bone fractures?

What’s the worst break of a bone you have seen?

I think mine was while playing rugby for Chesterfield Panthers RUFC against Amber Valley RUFC.

There’s was a ruck on the floor, bodies piled high and deep then we heard an almighty scream, strangely from a number of different players.

There had been a loud crack then it seems many players thought it could have been themselves, alas, it was a poor guy on the floor and his lower leg was at a right angle.

His sock was holding his leg and it didn’t look correct at all.

It looked horrendous.

So what’s this got to do with anything you are probably thinking.

University Research

Well, latest research from the University of Bristol, UK suggests that Magnesium supplementation in middle age is a superior way to prevent fractures and breaks. [1]

The results showed that middle aged men who had high levels of Magnesium in their blood stream just about halved their chances of a bone fracture or break over the next 25 years of their life.

Further research even opened the door on the benefits of combining this with Vitamin D3 in order to maximize the effect. [2] [3]


Both of which are proven to help stimulate more testosterone which can prevent osteoporosis.

Studies of in excess of 8000 hair samples demonstrated that 70% of people had insufficient levels of Magnesium in their body to perform properly and be healthy.

Modern farming practices and dietary changes are to blame for this apparent widespread Magnesium deficiency.

Intensive farming on a large industrial scale has seen a dramatic reduction of Magnesium content in the vegetables we eat. This decline has been ongoing since the 1950’s. [4]

Our high caffeine diet plus alcohol and the refined sugars with processed grains are also a contributing factor as well due to encouraging the kidneys to expel Magnesium.


Due to modern food production practices many people now suffer from lower levels of magnesium.

Studies have demonstrated that those people who have higher levels of magnesium are less likely to suffer from bone fractures than their counterparts who are suffering from a deficiency.

Furthermore, including D3 will also reduce the risk even further while contributing to a healthier level of testosterone, again, good to help prevent osteoporosis.
