Clearing Up The Calcium Confusion

Author: Dr. Stephen Chaney

should we take calcium supplementsShould we take calcium supplements?  You have every right to be confused about calcium supplementation. There have been a lot of conflicting headlines in recent months.

It has seemed like a no-brainer for years that calcium supplementation could help post-menopausal women and men over 50 avoid the debilitating effects of osteoporosis.

After all:

  • >99% of adults fail to get the USDA recommended 2.5-3 servings/day of dairy products.
  • 67% of women ages 19-50 and 90% of women over 50 fail to meet the RDA recommendations for calcium intake from diet alone.
  • Men do a little better (but only because we consume more food). 40% of men ages 19-50 and 80% of men over 50 fail to meet the RDA recommendations for calcium intake from diet alone.
  • Inadequate calcium intake over a lifetime is considered a major risk factor for osteoporosis.
  • Osteoporosis is serious business. It doesn’t just cause bone fractures. It can result in chronic pain, disability, long term nursing home care, and even death.

It’s no wonder that some experts have predicted that supplementation with calcium and vitamin D could save over $1 billion per year in health care cost savings. It is also why health professionals have recommended calcium supplementation for years, especially for postmenopausal women and men over 50.

However, recent headlines have claimed that calcium supplementation doesn’t really increase bone density or prevent osteoporosis (more about that later). Other headlines have suggested that calcium supplementation is actually bad for you. It may increase your risk of heart disease.

That’s why the general public, and even many doctors, are confused.  Should we take calcium supplements?  Everyone wants to know the answer to two questions:

  • Do calcium supplements work?
  • Are calcium supplements safe?

I will start with the second question first.

Are Calcium Supplements Safe?

are calcium supplements safeI have discussed the issue of calcium supplements and heart disease risk in a previous issue of Health Tips From the Professor. Briefly, the initial studies suggesting that calcium supplementation might increase the risk of heart attacks and cardiovascular disease were good studies, but they were small, short-term studies.

The initial studies raised an important question, so the scientific community stepped up to the plate and conducted larger, longer term studies to test the hypothesis. Both of those studies concluded that calcium supplementation posed no heart health risks.

Now a third major study on the subject has just been published (Raffield et al, Nutrition, Metabolism & Cardiovascular Disease, doi: 10.1016/j.numecd.2016.07.007). The study followed 6236 men and women ages 45-84 for an average of 10.3 years. The subjects were from four different race/ethnicity groups and came from 6 different locations in the United States. More importantly, there were 208 heart attacks and 641 diagnoses of cardiovascular disease during the study, so the sample size was large enough to accurately determine the relationship between calcium supplementation and heart disease.

The results were pretty straight forward:

  • The authors concluded: “[This study] does not support a substantial association of calcium supplement use with negative cardiovascular outcomes.” If you would like the plain-speak version of their conclusion, they were saying that they saw no increase in either heart attacks or overall cardiovascular disease in people taking calcium supplements.
  • If anything, they saw a slight decrease in heart attack risk in those taking calcium supplements, but this was not statistically significant.

In summary, the weight of evidence is pretty clear. Three major studies have now come to the same conclusion: Calcium supplementation does not increase the risk of either heart attacks or cardiovascular disease.

Of course, once information has been placed on the internet, it tends to stay there for a very long time – even if subsequent studies have proven it to be wrong. So the myth that calcium supplementation increases heart attack risk will probably be with us for a while.

So, should we take calcium supplements?  Let’s first investigate a little further.

 

Do Calcium Supplements Work?

do calcium supplements workAs I mention above, recent headlines have also suggested that calcium supplementation does not increase bone density, so it is unlikely to protect against osteoporosis. I analyzed the study behind those headlines in great detail in two previous issues of Health Tips From the Professor.

In Part 1 Calcium Supplements Prevent Bone Fractures  I pointed out the multiple weaknesses in the study that make it impossible to draw a meaningful conclusion from the data.

 

In Part 2 Preventing Osteoporosis  I discussed the conclusion that the study should have come to, namely: Adequate calcium intake is absolutely essential for strong bones, but calcium intake is only one component of a bone healthy lifestyle.

The bottom line is that calcium supplementation will be of little use if:

  • You aren’t getting adequate amounts of vitamin D and all of the other nutrients needed for bone formation from diet and supplementation.
  • You aren’t getting enough exercise to stimulate bone formation.
  • You are consuming bone dissolving foods or taking bone dissolving drugs.

Conversely, none of the other aspects of a bone healthy lifestyle matter if you aren’t getting enough calcium from diet and supplementation.

The bottom line is that you need to get adequate calcium and have a bone healthy lifestyle to build strong bones and prevent osteoporosis, and calcium supplementation is often essential to make sure you are getting adequate calcium.

 

Should We Take Calcium Supplements?

should we take calcium supplements nowShould we take calcium supplements?  If you are one of the millions of Americans who aren’t meeting the RDA guidelines for calcium from diet alone, the answer is an unqualified yes.  Calcium supplementation is safe, and it is cheap.  Osteoporosis is preventable, and it is not a disease to be trifled with.

However, you also need to be aware that calcium supplementation alone is unlikely to be effective unless you follow a bone healthy lifestyle of diet, exercise and appropriate supplementation to make sure you are getting all of the nutrients needed for bone formation.

Of course, it is always possible to get too much of a good thing. The RDA for calcium is 1,000 – 1,200 mg/day. The suggested upper limit (UL) for calcium is 2,000 – 3,000 mg/day.  I would aim closer to the RDA than the UL unless higher intakes are recommended by your health care professional.

 

The Bottom Line

 

  • 80% of men and 90% percent of women over 50 do not get enough calcium from their diet.
  • Consequently, doctors have consistently recommended calcium supplementation to prevent osteoporosis, and 50% of men and 60% of women over 60 currently consume calcium supplements on a regular basis.
  • Some small, short term studies suggested that calcium supplementation might increase the risk of heart disease, and warnings about calcium supplementation have been widely circulated on the internet. This hypothesis has been evaluated by three larger, longer term studies that have all concluded that calcium supplementation does not increase heart disease risk.
  • A recent study claimed that calcium supplementation was ineffective at increasing bone density, and that report has also been widely circulated. However, there are multiple weaknesses in the study that make it impossible to draw a meaningful conclusion from the data.
  • If you are one of the millions of Americans who aren’t meeting the RDA guidelines for calcium from diet alone, you should consider calcium supplementation.  It is safe.  It is effective when combined with a bone healthy lifestyle of diet, exercise, and appropriate supplementation.  Finally, it is cheap. Osteoporosis is preventable, and it is not a disease to be trifled with.
  • Of course, it is always possible to get too much of a good thing. The RDA for calcium is 1,000 – 1,200 mg/day. The suggested upper limit (UL) for calcium is 2,000 – 3,000 mg/day. I would aim closer to the RDA than the UL unless higher intakes are recommended by your health care professional.

    Calcium supplements were the wrong thing for me, I recently learned. I am hyperparathyroid, due to a tumor on one or more parathyroid glands. The calcium level in my blood had risen to 12.5 due to the malfunction of the parathyroid gland that regulates calcium in the bones, and more. I had osteoporosis—so all the more reason to take calcium? Wrong. For years, I faithfully took calcium, until this year. For years, doctors mused over my high blood calcium levels, above 10. However, due to thinning bones, every one recommended calcium supplements. Now that the tumor and malfunction is discovered, I halted all calcium and I’m preparing for surgery to remove the tumor(s) on my parathyroid gland(s), the only cure. One should not assume that thin bones are the only marker to take calcium.

      Dear Jennifer,
      You are correct in saying that calcium supplements won’t help if you are hyperparathyroid. However, I must wonder how your doctor’s missed that diagnosis. With thinning bones and high blood calcium levels, they should have tested you for hyperparathyroidism – not muse about it.

    Dr. Chaney, I would like additional information on where magnesium fits into the calcium/osteoporosis equation and in what ratio it should be included. Also, the same for strontium – how important is it for bone health and in what ratio?
    Thank you. Jeanie Porter

      Dear Jeanie,
      You should certainly aim for RDA intake of magnesium (300-310 mg/day for women and 400-420 mg/day for men. I have seen recommendations for a 2:1 ratio of calcium to magnesium. What many people neglect to say is that holds only up to RDA levels of calcium (which would correspond to 400-500 mg/day of magnesium. It is also important to know that excess magnesium can cause diarrhea. If you are taking a magnesium supplement, you get one that is sustained release.
      Strontium is more complicated. There is a form, strontium ranelate, that is prescribed to help increase bone density in women with osteoporosis in Europe. However, it has not been approved for use in this country, and the strontium supplements used in this country are unrelated to strontium ranelate. Unfortunately, there has been very little research on strontium supplements in this country. In short, strontium supplements may help increase bone density, but we have no idea what kind or how much would be beneficial.

    Hello Dr. Chaney.
    I’m interested in information regarding the effect of calcium supplementation on development of kidney stones.

      Dear Ruth,
      Some forms of kidney stones do contain calcium, but if your calcium intake is less than 4,000 mg/day, the kidney stones are probably not caused by excess calcium. Kidney stones are more likely caused by inadequate water intake, too little magnesium, too little B6, too much vitamin D, or hormone imbalances. If you are getting adequate water, magnesium, and B vitamins and still suffer from recurrent kidney stones, you should probably get a full workup by your physician.

What Is The Pectineus Muscle And Why Is It Important?

Spring Is In The Air

spring floridaI remember as a child we sang “Though April showers may come your way…they bring the flowers that bloom in May…”

Of course, here in Florida we are blessed with flowers all year, but there’s still a lovely feeling that happens in Spring.  It’s still cool enough most days to go out running, and the humidity is still low.  Traffic will soon be easing up as our friends from the north start their trek back home, and daylight savings time is giving us more time to get to the beach for sunset.  Lovely!

Fun Facts About Spring….

  • The earliest known use of the term “spring cleaning” was in 1857
  • The word “spring” has been used for the season since the 16th century
  • The first day of spring is called the vernal equinox
  • On the first day of spring, the sunrise and sunset are about 12 hours apart everywhere on earth
  • Spring fever isn’t just a saying. Experts say the body changes due to the temperature and can cause an upset in your health.
  • The actual start of spring varies from March 19th to the 21st, but it is commonly celebrated on the 21st.

Do you like to garden?  Now is the perfect time to get your gardens planted so you’ll have home grown veggies for the entire summer.  For me, it’s also a great time to do some spring cleaning and get the house in order before the summer closes all the windows and the air conditioning becomes our indoor relief.

But these activities can also cause a strain on muscles, so don’t forget to take care of yourself. If you put too much strain on muscles you haven’t used all winter, you can develop problems and need groin pain relief.

 

A Tiny Muscle Can Cause Groin Pain

groin pain relief pectineusLately I’ve had several clients come in because of groin pain that has their medical practitioners stumped.  Their symptoms are varied, but most complain that it feels like they hit their pubic bone with a rubber mallet.  Ouch!

One client loves to ride her horse, but the pain had prevented that for several weeks. Another was considering selling the motorcycle that she and her husband love because she just can’t sit on it anymore.

Several years ago, I had a male client tell me that he had this same pain and he was told it could be his prostrate causing the issue.  Fortunately, that wasn’t he problem at all.

The muscle that caused all these problems, and a lot more, is the Pectineus.

The Pectineus muscle originates on your pubic bone and inserts into the very top of your inner thigh bone (femur).

You can see the Pectineus and surrounding muscles more clearly by going to https://en.wikipedia.org/wiki/Pectineus_muscle

Most muscles have more than one function, and this is true for the Pectineus.  The function we’ll look at today is called adduction.  It brings your leg in toward midline.  If you think of a soccer player kicking the ball with the inside of his ankle, it was the Pectineus that helped draw his leg in so he could do the shot.

Each of my clients had pain while trying to bring their leg out so they could sit on their horse, or on their motorcycle.  The tight muscle was pulling on their pubic bone and causing a severe strain.

This muscle is easier to have someone else treat it for you because of its location but give it a try and see if you can locate & treat it yourself.

 

Groin Pain Relief

To reach the Pectineus, move the ball all the way up to the crease in your leg.  You can do the treatment with a ball, but because of the size of the muscle and its location, it’s easier to do it with your fingertips.

Sit as this athlete is sitting, and even bring your opposite leg up so your foot is flat on the floor.  For example, in this picture, the athlete would bring her right leg up so her right foot is on the floor, and then lean a bit further onto her left hip.  That opens up the area so she can reach a bit easier into the muscle while using her fingertips.

Press into the muscle, being careful to feel for a pulse, and moving if you feel one.  If the Pectineus is in spasm, you’ll know it immediately when you press on it.  If it’s not in spasm, you won’t be able to find it at all.

Remember to stay within your pain tolerance level, this isn’t a “no pain, no gain” situation.  Never go deeper than what feels tender, but not so much that you want to faint. Hold the pressure for 15 seconds. Then let up on the pressure, but keep your fingers in the same place.

Repeat this movement several times. Each time it will hurt less, and eventually it won’t hurt at all.  That’s when the muscle has completely released, and you will have relief from the pain.

It’s as simple as that!

Why stay in pain when it’s so easy to find the muscular source of the problem and eliminate it?
