How To Overcome Osteoporosis - You Need More Than Calcium

by Michael Sellar

Fractures caused by thinning and brittle bones affects one in three women and one in twelve men. It is a leading cause of death.

Bone mass peaks at around age 35. From then it's downhill all the way, especially for women whose bone mass is 10% - 15% less than men's at skeletal maturity and then suffer with accelerated bone loss for 8 - 10 years around the menopause when hormone levels decline. Hormone Replacement Therapy (HRT) is not the answer. It increases the risk of blood clotting, stroke, heart attack and cancer.

Calcium Can Cause Problems

Calcium is known to be important. However osteoporosis is not a calcium deficiency disease. Taking a calcium supplement alone is not recommended. It won't necessarily be absorbed into the bone. Instead it may remain in the blood and end up in the tissues causing its own health problems. While absorption is improved with vitamin D, it also has close relationships with other minerals.

Magnesium Is Also Important

Two-thirds of the magnesium in the body is found in the bones. It plays a vital role in the metabolism of calcium and bone. A deficiency of magnesium decreases the strength of bone, its volume and its development. It is positively associated with bone mineral density (BMD) as has been demonstrated in a number of population studies.

Strontium Can Stimulate Bone Formation

Early in the 20th century, studies were carried out that demonstrated that strontium in combination with calcium was more effective in mneralising bone that using calcium alone.

Boron Helps Bones To Heal

Boron is important in retaining calcium. According to Dr Rex Newnham, a world authority on the mineral, boron "will help broken bones mend in about half the normal time."

Manganese Is Needed For Bone Growth

To mineralise bone, manganese is required. Women with osteoporosis were found to have blood manganese levels at only 25% of the level of those who didn't have this condition. Deficiencies of manganese can give rise to abnormal growth of bone and cartilage as well as degeneration of the vertebral discs.

You Need Zinc, Copper & Silicon

Silicon is very rigid and is used by the body at calcification sites of bones. Zinc is necessary if bones are to form normally. Copper works in conjunction with zinc. Depletion leads to bone defects and calcium loss. Iron may also play an important role in bone formation.

Let's Not Forget Those Vitamins

Active calcium absorption in the intestines is facilitated by vitamin D, which is also involved with bone turnover. The status of vitamin D declines as we age and so deficiencies with ageing are common.

Vitamin K is also important in the metabolism of bone. It is required for bone formation, remodelling and repair. Epidemiological studies have shown that those people who lack vitamin K in the diet or in the circulation have a lower BMD or an increase in fractures.

Bone health can certainly be added to the long list of conditions that vitamin C can treat. It is required for the collageneous structure of the bone. Vitamin C may also protect the skeleton from oxidative stress especially for cigarette smokers. Smoking greatly increases the risk of hip fracture.

The bone remodelling process also requires vitamin A. Bone health is impaired with deficiencies.

There is an increased requirement for folic acid at the menopause, studies suggest. This happens because the efficiency of converting homocysteine - a toxic byproduct of protein metabolism - to less toxic compounds becomes impaired. Other nutrients that protect against the damaging effects of homocysteine include vitamin B6 and B12, so these may be helpful too.

And Finally

To conclude, bone health depends on more than just calcium. It requires a whole range of vitamins and minerals. This approach to ostoporosis is likely to be far more successful than current orthodox methods.
