Best source of calcium for menopause

A jog on a Hawaiian beach was all it took for Jan, a post-menopausal registered nurse, to fracture a bone in her foot. The sand shifted slightly as she took a step, and she felt the pain.

The vacation that Jan and her husband had anticipated for months? Ruined.

Jan always assumed she got enough calcium to keep her bones strong through her healthy diet and didn’t dwell on taking supplements before she entered menopause. Even her nursing training had only briefly touched upon nutrition.

If she had known the full truth, she might have spent more time in Hawaii outside of her hotel room, catching sun rays, instead of in the emergency room, getting x-rays. At Gennev HQ, we'll show why you need calcium, where to get it, and how much is enough.

The low-down on calcium and menopause

Minerals like calcium are vital to a healthy body. Your bones and teeth are home to 99% of your body’s calcium, while the remaining 1% helps your blood clot, your nervous system relay information, your muscles and blood vessels contract, and performs many other functions.

Your bones are constantly remodeling, breaking down and rebuilding to repair injuries and the daily wear and tear from normal activities.

During bone remodeling, your bones release calcium into the bloodstream and reabsorb it back. If your body doesn't have enough available calcium, it will use the calcium released into your blood to repair nerves, cells, and muscles instead of reabsorbing it into your skeleton.

In childhood, our bodies build more bone than we lose. This is how we grow. From adolescence until our thirties, our bones are the strongest because they build up and break down at an equal pace.

In our mid-thirties, this changes. We start to lose bone mass faster than we can maintain it.

Bone loss speeds up when your body’s estrogen production decreases during perimenopause and menopause, as estrogen aids calcium absorption from food and reabsorption into bones.

This all can lead to osteoporosis, a condition where bones become porous, brittle, and break easily, and its precursor, osteopenia. Forty percent of post-menopausal women in the US will have an osteoporosis-related fracture at some point in their lives. Some women have even died from osteoporosis hip-fractuces . Our friend Jan is one of these women. If your mother or grandmother had osteoporosis, you are at greater risk of developing it.

The calcium that you consumed as a teen and young adult is what shapes your risk of osteoporosis entering menopause.

‘This is great for my daughter,’ you might say, ‘but how does it help me now?’

You can’t have your teenage body back, including your bones, but keeping adequate levels of calcium in your bloodstream as you enter menopause and beyond can help your bones stay strong.

How much calcium for menopause do I need?

For more than 20 years, the USDA has defined the recommended daily allowance (RDA) of calcium for American women as 1000mg for women 50 and under and 1200mg for women over 50.

Some nutritionists now suggest that as low as 500mg per day may be enough. However, more research is needed to support this conclusion.

The best way to obtain the calcium you need is to...

The foods you eat are the most effective sources of calcium. Great sources of dietary calcium include yogurt (310 mg/serving), cheese (up to 210 mg/serving), sardines (325 mg/serving), cow’s milk (300 mg/serving), fortified soy milk or orange juice (300 mg/serving), tofu (205 mg/serving), and leafy greens (up to 360 mg/serving).

You can figure out how much calcium you’re getting from your diet by checking food labels or using a calcium calculator. Note: the “DV” (daily value) for calcium on food labels is based on 1000 mg, so “30% of DV” is 300 mg. If you are over 50, this isn’t 30% of your daily need!

Your doctor may also suggest taking a daily calcium supplement. For best absorption, take calcium supplements in doses smaller than 600mg; if you need more calcium than this, space out your supplement several times throughout the day

Calcium carbonate is the more affordable and available form of calcium supplement. You may already have calcium carbonate in your medicine cabinet as an antacid, like Tums or Rolaids. Take it with food, as stomach acid increases absorption.

Calcium citrate is another form of over-the-counter calcium. You can take it with or without food.

Side effects of calcium supplements may include gas, bloating, and constipation. Calcium carbonate tends to have more side effects than calcium citrate, so if you’re experiencing gastro discomfort, consider making the switch.

How to maximize calcium absorption

  • Take calcium with vitamin D. Your body needs vitamin D for optimal calcium absorption. Experts recommend 600 IU daily for women under 70 and 800 IU daily for women 71 and up. We get vitamin D naturally from the sun, but people with darker skin and those who see less sunlight due to location (hello, Seattle!) or limited mobility may need more. A multivitamin with 800-1000 IU vitamin D should be sufficient,
  • Take calcium at a different time than iron, zinc, or magnesium supplements or an iron-rich meal. Calcium can affect how your body absorbs these important minerals.
  • Add milk to your coffee or tea. Some studies suggest adverse effects of caffeine consumption on calcium metabolism. You can offset this by adding a few tablespoons of milk to your coffee. Or, treat yourself to a latte for even more calcium!
  • Avoid alcohol. While you may enjoy a glass of wine with dinner or a celebratory cocktail, alcohol increases calcium loss in your urine. (Alcohol can increase hot flashes, too--another reason to teetotal.)
  • Get the right amount of protein. Protein is essential for muscle and bone health, and the body absorbs more calcium when you’re getting your recommended daily allowance of protein. However, too much protein can increase urinary calcium loss. Aim for 46 grams every day.

What to watch out for

The amount of calcium that’s right for you may defer from the norm if…

  • You are taking other medications: Calcium supplements can interfere with antibiotics, medications to treat osteoporosis, and blood pressure medications. Consult your doctor or pharmacist before adding a calcium supplement to your diet.
  • You have a medical condition that interferes with calcium absorption: cancer, thyroid disorders, tuberculosis, and immobilization can impact the levels of calcium in your blood. Talk to your doctor to determine what’s best for you.

How much calcium should a postmenopausal woman take?

Getting more than the RDA value of calcium may increase your risk of kidney stones, heart disease from increased calcification in the arteries, and potentially colon cancer, though more evidence is needed to support these claims.

Preliminary research shows that vitamin K2, which plays an important role in calcium metabolization, can help with heart health if this is a concern for you; be sure to talk to your doctor first.

(Did you know that vitamin K is great for your bones, too? Women who get at least 110 micrograms of vitamin K daily are 30% less likely to break a hip than women who don’t!)

There is no catching up, only moving forward

Studies suggest that exceeding the RDA of calcium doesn’t actually increase bone health in patients with osteoporosis but meeting your daily needs now and taking preventative measures will reduce your risk of fracture in the future.

If you are 65+ or have risk factors for osteoporosis before entering menopause, get a bone mineral density test (BMD) to evaluate your bone health before you break something.

And remember that calcium is only part of the equation for strong bones: if you want toprevent osteoporosis, exercise, a healthy diet, and refraining from smoking.

Jan now maintains her bone strength by eating calcium-rich foods, doing yoga with her husband, and walking to the grocery store instead of driving. She can focus her attention on her book club and adult children knowing that she’s doing everything she can to prevent another fracture.

Best source of calcium for menopause
This helpsheet aims to equip you with everything  you need to know about your calcium requirements in menopause.  We cover the different types  of calcium available, the main dietary sources and much more.

You probably know that one of the unfortunate health consequences of early menopause and premature ovarian failure (POF) is an increased risk of osteoporosis — the weakening and loss of bone (source).

Likewise, you also probably know that making sure you get enough calcium is one of the most widely recommended ways of helping to keep your bones strong.

But there are so many different forms of calcium out there — and so many different opinions, claims, and so forth… it can be very confusing.

Let’s start with the basics: getting enough calcium is a definite must where bone-building is concerned.  But many of us don’t get nearly enough calcium. The National Institutes of Health recommends that if you are in menopause, you should get at least 1,000 mg of calcium a day if you are on hormone replacement therapy (HRT), and 1500 mg if you aren’t.

But this recommended dosage doesn’t just refer to calcium; it refers to elemental calcium.  In plain English, this is the amount of calcium that is available to actually work in your body. This is one reason why, if you opt for calcium supplements, it’s wise to read the labels carefully!

Best source of calcium for menopause

Just because the label says the calcium supplement has, say, 1250 mg, doesn’t mean that this is the amount of elemental calcium in it. Often the label will list the elemental calcium; other times it’s not mentioned. So to be sure you’re getting the calcium you need, it makes sense to know what percentage of elemental calcium is in the different forms of calcium available.

There’s more about this in our explanation of calcium supplements below.  But before you get to that step, you first have to determine how much calcium you’re currently getting.

Take a look at your daily diet to see if you can and should up your calcium intake through the foods you eat. In general, your best bets for calcium-rich foods are non-fat or low-fat dairy products, salmon, sardines with the bones, green leafy vegetables and tofu.

Perhaps you’re a little inconsistent on it… some days, you do get enough; other days, you’re not reaching your target. Well, when you’re dealing with the possibility of osteoporosis, you can’t afford to be casual about calcium consumption.

So if you think you’re not getting enough calcium in your diet each day, you have two choices in this case: either start religiously eating calcium-rich foods… or take calcium supplements.

Because those of us with early menopause and premature ovarian failure (POF) are at such a high risk for bone loss, calcium supplementation usually makes a lot of sense. It’s easy — and you can be assured that you’re getting a certain level of calcium.

It does get a little confusing, though, when it comes time to choosing the optimal calcium supplement. There are so many out there all purporting to do the same thing, but there are differences between the different forms.

This is the form of calcium most often recommended by doctors, chiefly because it is the most easily absorbed. This claim to fame may not apply to you since it is older  women who tend to have more problems with digestion as their stomach acid production goes down, not women in their 20s and 30s.

But if you have any problems with digestion — or just want a calcium that isn’t hard on your stomach, calcium citrate probably makes sense. There is one drawback to this type of calcium: it contains only about 21% elemental calcium, so to get enough calcium, you usually have to take more tablets… which winds up costing more.

In addition, in spite of its stomach-friendly reputation, it may cause stomach upset or diarrhea. If you choose this type of calcium, you should take it between meals or just before bedtime.

This is the other most widely-used form of calcium. It is not as easily absorbed as calcium citrate, but is the most concentrated form of calcium with 40 percent  elemental calcium (which usually makes it the best value option!)

In other words, if you take a 1250 mg of calcium carbonate tablet, you’re getting 500 mg of elemental calcium. This is also the form of calcium that has been studied the most — and there’s another side benefit: It also can act as an antacid.

On the negative side, though, it can cause constipation and bloating. If you take this, it’s a good idea to drink more water than usual — and take it in two or more doses, rather than all at one time. You may also want to chew it to make it more easily absorbed into your system. Unlike calcium citrate, you should take this with  (not between) meals.

This contains roughly 39% elemental calcium — and is another easily digested form of calcium. It’s also the type of calcium used to fortify many foods such as orange juice and soy milk. The only problem? It’s among the most expensive forms of calcium.

Like calcium citrate, Calcium Lactate and Calcium Gluconate are less concentrated forms of calcium (containing about 15 percent elemental calcium), and are similar to calcium citrate in terms of absorbability and lack of side effects.

But they usually cost more than calcium citrate — as much as three to ten times more — so you’re typically better off avoiding these and opting for another form of calcium.

Finally, there are calcium-based antacids — products like Tums and Rolaids Calcium Rich, which are probably one of the cheapest ways of getting calcium. These contain calcium carbonate, so usually offer you about 40% elemental calcium.

For example, if you chew a regular Tums tablet (which contains 500 mg of calcium), you’ll get about 200 mg of elemental calcium. Many women like them because you can chew them instead of swallowing. If you opt for this form of calcium, you should take them between meals. Also be sure to read the label carefully. You don’t want to get an antacid that includes aluminum because that can leach calcium from your system.

    It is a good idea to take your calcium twice a day, inside of in one dose, because your body can absorb only 600 milligrams of elemental calcium at a time.

•    Do not take calcium with iron, because it interferes with its absorption.

    Also avoid taking calcium supplements with high-fiber meals or bulk laxatives, as they can cut down on the amount of calcium you absorb.

    Be sure that your calcium is actually doing what you’re paying for by putting your tablets through this simple absorbability test… Drop one tablet in a small glass or bowl with white vinegar and stir it every few minutes.

After fifteen minutes to half an hour has passed, the pill should have disintegrated. If it hasn’t dissolved in the vinegar, it won’t dissolve in your stomach either — making it essentially useless. In this case, you should get another brand or try another form.

    Where calcium is concerned, you can  get too much of a good thing. Over 2,000 milligrams a day of elemental calcium may pose problems for your kidneys. So if you have had kidney stones or have a family history of them, talk to your doctor before taking calcium supplements.

To make calcium work well, you need other vitamins and minerals to help it along. Some of these are available in combination with calcium.  Others are in multi-vitamins or trace mineral compounds, or you can take them individually.  Finally, of course, can get them through a well-balanced diet.

Where you get them isn’t really the issue; the key is being sure you are getting them to get the most out of your calcium intake. The calcium helpers, then are:

Vitamin D is essential for helping your body absorb calcium. While you can get Vitamin D from the sun, it’s not always considered the best way since you can’t be sure you’re getting enough (and it’s tough to get if you live in a very cloudy area or use sunscreen.)

In fact, according to one study, Vitamin D deficiency is much more common than previously thought. Most interestingly, thirty-seven percent of the women in the study who had low Vitamin D levels mistakenly thought  that they were consuming at least the minimum requirement of Vitamin D.

Since Vitamin D is so vital in the fight against osteoporosis, it’s probably best to take supplementation, then, to be sure you’re getting what you need. Nowadays, most doctors agree that you need at least 1000 to 2000 IU of vitamin D3.

You can also get Vitamin D in your diet from fatty fish (salmon, sardines, herring); fortified milk and other dairy products; egg yolks; and fortified cereals and breads.

Magnesium — which is very commonly found in calcium supplements — is also crucial for optimum skeletal health. In addition, it appears to hep fight fatigue and boost energy levels, as well as helping protect against heart disease.

Generally, you should take a dosage equal to half of the calcium dosage you’re taking. The usual dosage is about 200 to 750 I Us depending on how much calcium you take.

Some good natural sources of magnesium include: whole grains; dark-green leafy vegetables; milk and dairy products; nuts; meat and fish; and dried cooked beans, especially soy beans.

Boron is another mineral that helps prevent bone loss and it is often included in calcium supplements.

It’s generally recommended you get about 3 to 6 mg of boron daily. Good natural sources of boron include fruits (including apples and pears); green and dark-yellow vegetables (including broccoli and carrots); and nuts (including almonds and hazelnuts).

Vitamin K is another key player where bone health is concerned. Most women, however, get enough Vitamin K through their diet — since it’s found in many vegetables.

You also need trace amounts of the following minerals: copper, zinc, manganese and silicon (all of which are usually included in multi-vitamins or multi-mineral supplements).

Scientific studies have shown that women diagnosed with early menopause or premature ovarian failure have an increased risk of osteoporosis.  It’s therefore vital we do everything we can (in conjunction with our doctor) to minimize and manage these long-term risks.

One important step you can take on your own is to ensure an optimal calcium intake alongside a diet that provides essential bone-friendly nutrients.
