You Need More Than Calcium To Overcome Osteoporosis

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 reaches a peak at about the age of 35. After that it declines, especially for women who have 10 % - 15% less bone mass than men at skeletal maturity. There is then an accelerated loss of bone for up to a decade around the menopause when there is a decline in hormone levels. The answer is not Hormone Replacement Therapy (HRT). This increases the risk of heart attack, strokes, blood clots and cancer.

Calcium Can Cause Problems If Taken Alone

Calcium is of course important. However osteoporosis is not a deficiency disease caused by a lack of calcium. It is not recommended to take calcium supplements on their own. There is no certainty that the calcium will end up in the bones. It could find its way into tissues instead. This may create its own health problems. Vitamin D certainly improves the absorption of calcium, but calcium has important synergistic relationships with a range of other minerals.

Magnesium Is Also Important

One third of the body's magnesium is found in tissues, two-thirds is found in the bones. Its role is crucial in calcium and bone metabolism. Bone strength, volume and development is decreased in deficiency states. A number of population studies show a positive association with bone mineral density (BMD).

Strontium Can Stimulate Bone Formation

In the early part of the 20th century studies showed strontium to be effective in stimulating rapid formation of bone and that strontium and calcium were superior to calcium alone in mineralizing bone.

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

Manganese is needed to mineralize the bones. Osteoporotic women were found to have blood manganese levels at only 25% of the level of women without osteoporosis. Abnormal bone and cartilage growth can arise with deficiencies. There may also be degeneration of the 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

Vitamin D is required for calcium to be absorbed in the intestines. It also helps regulate bone turnover. Deficiencies are quite common in the elderly since its status declines with age.

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.

Studies suggest menopause is associated with an increased requirement for folic acid because of decreased efficiency at converting homocysteine - a toxic byproduct of protein metabolism - to less toxic compounds. For this reason other nutrients that offer protection from homocysteine such as vitamin B6 and B12 may also be important.

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.
