Osteoporosis
A crippling disease that is
preventable and reversible.
By John R. Lee, M.D. and Virginia Hopkins
Although cardiovascular disease is the leading cause of death among American
women, osteoporosis is the disease they are most likely to develop as they age. Four out of ten
white women in the U.S. will fracture a hip, spine, or forearm due to osteoporosis. As many as five
out of ten will develop small fractures in their spine, causing great pain and a shrinking in
height. This amounts to 15 to 20 million people affected by a crippling and painful disease that is
almost entirely preventable and reversible.
Osteoporosis is a gradual decrease in bone mass and density that can begin as
early as the teen years. Bone mass should be at its peak in our late 20s or early 30s, but thanks
to a poor diet and lack of exercise, many women are already losing bone in their 20s. Bone loss
occurs more rapidly in women than in men, especially right around the time of menopause, when an
abrupt drop in estrogen and progesterone accelerates bone loss.
When you think of your bones you may imagine a dead skeleton, but your bones are
living tissue, just like the rest of your body, and they need a good supply of nutrients and
regular exercise. New bone is constantly being made, while old bone is being reabsorbed and
excreted by the body. Our larger long bones, such as our arm bones and leg bones, are very dense,
and they are completely replaced about every 10-12 years. Our less dense bones, such as our spine
and the ends of our long bones, are less dense and turn over every 2-3 years. Thus, as you can see,
we always have the opportunity to be creating better bone for ourselves.
We all hear about how having enough calcium in the diet and taking estrogen can
help prevent osteoporosis, but there is a much bigger nutritional and lifestyle picture to look at
when we are talking about preventing this bone-robbing disease. You'll be happy to know that for
the vast majority of women, there is no need to take estrogen to prevent osteoporosis.
The most important element of bones is minerals. Without minerals we don't have
bones. The most important bone minerals are calcium, magnesium, potassium, phosphorous and
fluoride. Equally important is the balance between the minerals. Too much phosphorous or fluoride
will create poor bone structure. (Nearly all of us already ingest too much fluoride.) Without
enough magnesium, the calcium can't be absorbed onto the bone. Vitamins are also involved. For
example, vitamin B6 works with magnesium to get calcium onto your bones.
The hormones testosterone, estrogen and progesterone are also actively involved
in the making and unmaking of bone. Testosterone and progesterone build bone, while estrogen
appears to indirectly slow bone loss.
In osteoporosis, the old bone is being reabsorbed faster than new bone is being
made, causing the bones to lose density and become thinner and more porous. The integrity and
strength of our bones is related to bone mass and density. The bones of a woman with osteoporosis
gradually become thinner and more fragile. A progressive loss of bone mass may continue until the
skeleton is no longer strong enough to support itself. When that happens, bones can spontaneously
fracture. As bones become more fragile, falls or bumps that would not have hurt us before, can
cause a fracture. Bone loss seems to be most severe in the spine, wrists and hips. Unfortunately
there are usually no signs or symptoms of osteoporosis until a fracture occurs.
Early Signs of Osteoporosis

How Aware of
Osteoporosis Are You?
A Gallup poll sponsored by the National Osteoporosis Foundation found that:
- 75% of women believed they were familiar with osteoporosis, but
- 80% were not aware that it was responsible for disabling fractures,
- 90% percent were surprised to learn that osteoporosis frequently causes
death, and
- 60% could not identify the risk factors of osteoporosis.
Should You Take Hormone Replacement Therapy to Prevent Osteoporosis?
There is a misperception that osteoporosis begins at menopause. In reality, bone
mass begins declining in most women in their mid-thirties, accelerates for 3-5 years around the
time of menopause, and then continues to decline at the rate of about 1-1.5% per year. Because bone
loss accelerates at menopause, and because estrogen levels decline at menopause, conventional
medicine has adopted the belief that osteoporosis is an estrogen deficiency disease that can be
cured with estrogen replacement therapy. This is only partly true. The missing piece of this puzzle
is diet and lifestyle, plus the bone-building hormone progesterone, which drops much more
precipitously at menopause than estrogen does. (When I refer to progesterone, I mean the natural
hormone, not the synthetic progestins. Read my books for details on the differences.)
There is no question that estrogen can slow bone loss around the time of
menopause, but the scientific evidence is very clear that after 5-6 years, bone loss continues at
the same rate, with or without estrogen. A very large study published in the New England Journal
of Medicine in 1995, studying risk factors for hip fractures in white women, which followed
over 9500 women for eight years, found no benefit in estrogen supplementation in women over the age
of 65. If estrogen was the only known treatment for osteoporosis, it might be worth taking it to
get the small saving in bone density, despite all the risks and side effects. But since it's clear
that progesterone, combined with proper diet and exercise, steadily increases bone density
regardless of age, there are very few women who should ever need to take estrogen for
osteoporosis.
Women who need estrogen tend to be those who are petite, slim and small-boned.
After menopause, a woman’s fat cells make estrogen, but a slim woman
may not be making enough to keep up with bone loss. Those
women may need a very low dose of estradiol.
There are a number of pharmaceutical drugs being used to treat osteoporosis,
none of which work very well, and all of which have unpleasant side effects. One of the best known
is fosamax, a biphosphonate drug that can slow bone loss. Unfortunately, the old bone which is
saved by using fosamax is eventually structurally unsound, and after three or four years it has no
benefit, and I suspect it tends to increase the rate of hip fracture after about five years.
For awhile fluoride was being touted as an osteoporosis drug, but like fosamax, it only slows bone
loss temporarily, and the long term consequence is an increased rate of hip fracture due to
structurally unsound bone. Another conventional medicine osteoporosis drug is called
Calcitonin-salmon (Calcimar). This is a hormone made by the thyroid gland that can temporarily slow
bone loss. Again, the long term side effects are not well known, and its effectiveness diminishes
rapidly after a few years.
Progesterone and Osteoporosis
One of the most important factors in osteoporosis is a lack of progesterone,
which causes a decrease in new bone formation. Years of clinical experience giving women
progesterone showed me that using a natural progesterone cream will actively increase bone mass and
density and can reverse osteoporosis. These patients consistently show as much as a 29
percent increase in bone mineral density in three years or less of progesterone therapy. After
treating hundreds of patients with osteoporosis over a period of 15 years, I found that those women
with the lowest bone densities experienced the greatest relative improvement, and those who had
good bone density to begin with, maintained their strong bones.
Postmenopausal women using a transdermal (on the skin) progesterone cream or oil
should use the equivalent of 15-20 mg daily for three weeks out of the month, with a week off each
month to maintain the sensitivity of the progesterone receptors. You can read my book
What Your Doctor May Not Tell You About
Menopause for details on how to use progesterone cream.
Exercise for Strong Bones: Use 'Em Or Lose 'Em
Lack of exercise is one of the primary causes of osteoporosis. Using your bones
keeps them strong and healthy. Weight-bearing exercise is the only thing besides progesterone found
to actually increase bone density in older women. By weight-bearing I mean exercise that
uses your bones. Brisk walking counts as weight-bearing exercise, but add some hand-held weights
and it's even better. Pushing a vacuum cleaner or lawn mower, gardening, dancing, and aerobic
exercise also qualify.
Your exercise plan should include a minimum of 20 minutes of weight bearing
exercise three to four times a week. An hour is even better. In contrast to women who exercise,
those who don't continue to lose bone, regardless of what else they are doing. Studies of elderly
people who fall and break a bone show that these people had poor flexibility, poor leg strength,
instability when first standing, and difficulty getting up and down in a chair. Exercise can help
increase flexibility, strength, and coordination. A weight lifting program of just half an hour
three to four times a week can significantly improve bone density. You don't need to go to the gym
to do a weight lifting program. You can lift a can of peas or a small carton of milk. Women with
advanced osteoporosis should work with a physical therapist to create a safe, effective program to
reduce the risk of fracture. The Asian movement exercises such as yoga, tai chi and chi kung can
also be excellent for improving strength, flexibility and coordination.

Dietary
Guidelines for Osteoporosis
You May Be Surprised to Learn that this is Not a Calcium Deficiency Disease
Now that scientists know the process of preventing osteoporosis begins early in
life, (check out more articles on osteoporosis at we're hearing
about sugary drinks fortified with calcium for teenagers, antacids with calcium, and calcium
supplements. Osteoporosis is not a calcium deficiency disease, it is a disease of excessive calcium
loss. In other words, you can take all the calcium supplements you want, but if your diet and
lifestyle choices are unhealthy, or you're taking prescription drugs that cause you to lose
calcium, you will still lose more calcium from your bones than you can take in through diet.
In fact, getting adequate calcium is only a small part of the prevention
picture. Please pass up the sugary drinks and antacids. The damage that refined sugar will do to a
growing teenage body or even an adult body far outweighs any benefit that might come from a little
calcium supplementation. There is even some evidence that sugar depletes calcium, so the added
calcium in these drinks may only be balancing out the damage done by the sugar. The same goes for
antacids containing calcium. Since antacids tend to cause you to lose calcium, the added calcium
may only offset that damage.
Having pointed out that osteoporosis is not a calcium deficiency disease, I want
to assure you that getting adequate calcium is an important factor in preventing
osteoporosis. Some good food sources of calcium are snow peas, broccoli, leafy green vegetables
such as spinach, kale, beet and turnip greens; almonds, figs, beans, nonfat milk, yogurt and
cottage cheese. I don't want you to depend on milk to get your calcium. This is because milk has a
poor calcium to magnesium ratio. Your body needs a certain amount of magnesium in order to get the
calcium into your bones -- without magnesium, calcium can't build strong bones.
In fact, magnesium deficiency may be more common in women with osteoporosis than
calcium deficiency. Although many fruits and vegetables have some magnesium in them, especially
good sources of magnesium are whole grains, wheat bran, leafy green vegetables, nuts (almonds are a
very rich source of magnesium and calcium), beans, bananas and apricots.
Trace minerals are also important in helping your body absorb calcium. Eating
plenty of green leafy vegetables gives you calcium along with these helpful trace minerals. Boron
and manganese are especially important. Foods that contain boron include apples, legumes, almonds,
pears and green, leafy vegetables. Foods that include manganese include ginger, buckwheat and oats.
The organic matter in our bones consists mainly of collagen, the "glue" that
holds together skin, ligaments, tendons and bones. Zinc, copper, beta carotene and vitamin C are
all important to the formation and maintenance of collagen in the body.
A Calcium/Magnesium Supplement is Good Health Insurance
Everyone should have at least 600 mg of easy-to-absorb calcium daily. Although
you can easily get that much with a healthy diet, taking a calcium/magnesium supplement is an
excellent form of health insurance. In fact, calcium supplements can help slow bone loss in some
women. To be incorporated into bone, calcium requires the help of enzymes, which require magnesium
and vitamin B6 to work properly. We tend to be more deficient in magnesium and B6 than we do in
calcium.
All calcium supplements are not the same. The best absorbed form is called
calcium citrate. Avoid the oyster shell calcium, as it can be contaminated with heavy metals. If
you're female and over the age of 12, you should be taking 300 mg of calcium, combined with 200 mg
of magnesium every day. If you can find a formula that also includes vitamin B6, so much the
better. Menopausal women can take 600 mg of calcium daily with 400 mg of magnesium.
Sunshine is the Best Medicine
Vitamin D is another important ingredient in the recipe for strong bones because
it stimulates the absorption of calcium. A deficiency of vitamin D can cause calcium loss. The best
way to get vitamin D is from direct sunlight on the skin. Sunlight stimulates a chain of events in
the skin leading to the production of vitamin D in the liver and kidneys. (This is why liver and
kidney disease can produce a vitamin D deficiency.) Going outside for just a few minutes a day can
give us all the vitamin D we need, and yet many people don't even do that. They go from their home,
to their car, to their office, and back home, without spending more than a few seconds outdoors.
Many elderly people are unable to get outside without assistance, but this should be a priority for
their caretakers.
Stomach Acid
As we age, we tend to produce less stomach acid. To be absorbed, calcium,
requires vitamin D and stomach acid. For this reason, it's important to avoid antacids and
the H2 blockers such as Tagamet and Zantac, which block or suppress the secretion of stomach acid.
Contrary to what the makers of heartburn and indigestion remedies would have you believe, the last
thing in the world most people need is less stomach acid. Heartburn and indigestion are
caused by poor eating habits and a lack of stomach acid. Ulcers are caused by a bacteria,
not by too much stomach acid. A simple way to improve your calcium absorption may be to take a
betaine hydrochloride supplement just before or with meals, to increase your stomach acid. You can
find betaine hydrochloride at your health food store.
The Collagen Vitamins and Minerals
Collagen is the tissue that makes up your bone. To build collagen you need
vitamin A (or beta carotene), zinc and vitamin C. Vitamin C is especially important, as it is the
primary ingredient in the collagen matrix. I recommend you take 1,000 mg daily of vitamin C, in an
esterfied form to prevent stomach problems.
Diet
- Reduce or eliminate soda pop and other carbonated beverages.
- Keep meat consumption to a reasonable level (no more than once a day).
- Eat plenty of fresh, green vegetables and whole grains.
- Eat foods high in flavonoids, which help stabilize collagen structures,
such as blueberries, raspberries and hawthorne berries.
Supplements
- Calcium citrate, 600 mg daily with meals
- Magnesium (citrate, glycinate, oxide or malate), 600-900 mg daily with
meals
- Folic acid, 200 mcg daily
- Vitamin C, 1,000 mg twice daily
- Vitamin B6, 50-100 mg daily between meals
- Zinc, 15 mg daily with meals
- Beta carotene, 15,000 iu daily
- Trace Minerals, including 1-3 mg of boron and manganese.

To Prevent
Osteoporosis AVOID:
Soda Pop and a High protein Diet
I believe that one of the leading contributors to osteoporosis in the U.S. is
carbonated soft drinks containing phosphorous. Research has shown a direct link between too much
phosphorous and calcium loss. If you're guzzling down a couple of fizzy soft drinks a day, you're
most likely creating bone loss.
Our other source of excessive phosphorous in the U.S. is eating too much meat.
The average American gets more than enough protein, so for most of us it can only help to cut down
on our meat consumption. A recent trend among those who love food but don't love the consequences
of too much fat and protein is to use meat as a garnish or flavoring in a meal, rather than as a
major portion. Fill up on vegetables and complex carbohydrates (whole grains, potatoes, rice, corn,
beans), and use meat to enrich your meals. Beans are an excellent and nutritious source of protein
and contain many important vitamins and minerals.
Coffee, Alcohol, and Cigarette Smoking
Here's yet another good reason to either give up coffee and alcohol or use them
in moderation. And do I need to tell you how important it is to stop smoking now! (It's
never too late to reap the benefits of quitting smoking.) Each of these substances creates a
negative calcium balance in the body. Substances called phytates and oxylates bind with calcium in
the large intestine and form insoluble salts, rendering the calcium useless. The bone mineral
content of smokers is 15-30% lower in women and 10-20% lower in men. Cigarette smoking is a
significant risk factor for osteoporosis. Twice as many women with osteoporosis smoke as compared
with women who do not have osteoporosis.
Aluminum
Don't take antacids with aluminum and don't use aluminum cooking pots. It has
been shown that small amounts of aluminum-containing antacids increase the urinary and fecal
excretion of calcium, inhibit absorption of fluoride, and inhibit absorption of phosphorus,
creating a negative calcium balance. The calcium is excreted instead of being utilized.
Diuretics
Diuretics are medicines that cause water loss in the body. Along with the water
you lose minerals, most notably calcium, magnesium and potassium. They are commonly used in
conventional medicine to treat high blood pressure, swelling of the lower legs, and congestive
heart disease. People who use diuretics have a higher risk of fracture. If you need to use a
diuretic, try a gentle herbal one such as dandelion root in a tincture, capsule or tea.
Fluoride
What's so bad about fluoride? You probably think it just builds good teeth.
There is good, solid scientific evidence that fluoridated drinking water increases your risk of hip
fractures by 20-40%. So much fluoride has been put into our water and toothpaste over the past 30
years that levels in our water, food and drink are very high. While eating a normal diet the
average person exceeds the recommended dose. There is also evidence that ingesting high levels of
fluoride can cause abnormal bone growth. Please avoid fluoride, in all forms including toothpastes
and mouthwashes.
You can be thankful if you live in an unfluoridated community because it's not
easy to get rid of fluoride in your tap water. Distillation and reverse osmosis are the only two
reliable methods for removing fluoride. Other water filters may work at eliminating fluoride for a
short period of time, but fluoride binds so strongly and quickly to filter materials such as
charcoal, that the binding sites become fully occupied after a short time. If you are at a high
risk for osteoporosis, I recommend you spend the money on a water filter that removes fluoride.
High Dose Cortisone
A well known risk for osteoporosis is long term treatment with the synthetic
cortisones such as Prednisone. Since the cortisones (or more properly, glucocorticoids) are closely
related to progesterone in their molecular structure, the theory is that they compete for the same
receptor sites on bone-building cells. However, while progesterone gives bones the message to grow,
the cortisones give bones the message to stop growing. If you must be on a cortisone, talk to your
doctor about using a low dose natural cortisone called hydrocortisone rather than the synthetic
cortisones. You can refer him or her to the book Safe Uses of Cortisol by William
Jefferies.
Bone Mineral Density (BMD) Testing
One of the best ways to find out if you're losing bone is to have someone
measure your height, and then check it every six months or so. If you start losing height, that's a
sure sign that you're losing bone on your spine. I recommend that women at risk for osteoporosis
get a bone mineral density measurement as they're going into menopause. That way you'll have a
baseline with which to compare later bone density tests, to measure your progress. The safest and
most accurate ways to measure bone are with Photon Absorptiometry, and Dual Energy X-ray
Absorbtiometry (DEXA), which is 96-98% accurate and uses very low-dose x-rays. I don't recommend
CAT scans, as they use too high a level of X-rays. A newer technique for measuring bone loss is
called "Urinary Excretion of Pyridinium," which measures a substance in the urine that can indicate
rapid bone turnover rate.

interpret them, please read the October 98
issue of my newsletter.
OSTEOPOROSIS PREVENTION AND REVERSAL In a Nutshell
Lifestyle
- If you're smoking, stop now.
- Reduce or eliminate coffee and alcohol. (No more than one cup of coffee
and one alcohol drink per day. If you are at a high risk I advise elimination.)
- Get some weight bearing exercise at least one hour three times a week or 20
minutes daily.
- Avoid antacids, and hydrochloric acid (H2) blockers such as Tagamet,
Zantac and Pepcid.
- Avoid prescription drugs that cause bone loss, such as diuretics and
synthetic cortisones.
- If you are over the age of 50, avoid fluoride in toothpastes, mouthwash
and tap water. If you live in a fluoridated community and are at a high risk for osteoporosis,
invest in a water filter that eliminates fluoride.
