You Need More Than Calcium To Overcome Osteoporosis

by Michael Sellar

Thinning and brittle bones give rise to fractures. This affects a third of women and one out of every twelve men. It is a major cause of death.

At around the age of 35 bone mass peaks. From then on it declines, especially for females who have ten to fifteen percent less bone mass than men at skeletal maturity. There is an additional loss of bone mass for eight to ten years from a reduction in hormone levels at the menopause. Many choose to take Hormone Replacement Therapy (HRT), but this is not the answer. HRT increases the risk of blood clots, heart attacks, strokes and cancer.

Calcium Can Cause Problems If Taken Alone

Calcium is important. But osteoporosis is not disease caused by calcium deficiency. Just taking calcium supplements is not the answer. There is no guarantee is will be absorbed into the bone. It could remain in the blood and be delivered to non bone tissues where it may create its own problems. Vitamin D improves the absorption of calcium but it is also works in synergy with other minerals.

Magnesium Is Also Important

Two-thirds of the body's magnesium is found in the bones. It plays a crucial role in calcium and bone metabolism. Deficiency causes decreased bone strength and volume and poor development. A positive association with Bone Mineral Density (BMD) has been demonstrated in many 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

Calcium is better retained in the bone in the presence of boron. According to world authority on boron, Dr Rex Newnham, boron can speed up the healing of broken bones in half the usual time.

Manganese Is Required For Bone Growth

Manganese is required to mineralise the bone. Blood manganese levels in osteoporotic women were found to be only 25% of those without osteoporosis. Deficiencies lead to abnormal bone and cartilage growth and degeneration of vertebral discs.

You Need Silicon, Zinc & Copper

Silicon is a rigid substance and the body uses it at the calcification sites of bones. Zinc is required for bone to form normally. Copper works in association with zinc. A lack of this mineral can lead to defects in the bone and calcium loss. Iron may also have a role to play in bone formation.

Let's Not Forget Those Important 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.

Vitamin C is needed to make collagen within the bone structure. It may also offer some skeletal protection against free radicals and oxidative stress. This is especially the case for cigaretter smokers. Smoking is associated with an increase in the risk of hip fracture.

Vitamin A is important in the bone remodelling process. Deficiencies are known to be detrimental to bone health.

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

In conclusion, bone health depends on a sufficient supply of a wide range of nutrients that goes well beyond calcium and vitamin D. Such an approach is likely to be far more successful than current orthodox approaches which leave a lot to be desired.
