When our third child started to eat solid foods, we found out that he had a pretty severe dairy allergy. It started with bad gas and mucousy stools, then progressed to skin reactions and even worse digestive problems.

Food allergies are common in babies born early, and my son was five weeks premature (that whole story and my other birth stories here).

In response to this new information, I cut dairy out of my diet because I was still breastfeeding my son. Even though I was only eating raw and organic forms of dairy before, I found that I felt much better, I lost weight more quickly, and had smoother skin in response to the dietary change. While I was sad to give up my favorite raw cheeses, was glad to know that my body didn’t tolerate dairy well, either.

While the baby and I felt better without cow’s milk products, there was a new thing to be concerned about: How will we get enough calcium without dairy?

How Much Calcium Do We Need?

Calcium is the most abundant mineral in the human body. As we know, it is vital for strong bones and teeth, and it’s also important for muscle development, healthy blood pressure, and skin health.

The recommended daily intake is 1,000 mg of calcium for men and women, and those calcium requirements rise to about 1,200 mg for older adults. Tracking your intake can be tricky because calcium isn’t always properly absorbed — meaning we generally might need to consume more than we think.

For reference, calcium from dairy products is about 30-35% bioavailable. Other calcium-rich foods that are more absorbable than dairy include fish with bones and cooked veggies like bok choy, kale, and broccoli.

Some foods are often suggested as a good dietary source of calcium but are not as absorbable. For example, spinach contains only around 5% of bioavailable calcium.

Middle-of-the-line options are edamame and soy milk (24% bioavailable), white beans (22%), and sesame seeds (21%).

Bottom line: When tracking your calcium intake, it’s important to consider how easily our bodies can absorb the nutrients in different food sources.

Vitamins That Help the Body Absorb Calcium

Another factor to consider in the bioavailability of calcium is the other vitamins you’re getting in your diet.

Vitamin D is required for the proper absorption of calcium, with one study showing that people who were deficient in vitamin D only absorbed 14% of the calcium from food, versus 58% absorption from those with adequate levels. Fortunately, many natural food sources of calcium (like fatty fish) are also good sources of vitamin D.

It’s also important to get enough magnesium, as it helps to convert vitamin D into its active form. Magnesium is also used in the creation of the hormone calcitonin. Calcitonin keeps calcium in the bones and not in the bloodstream, lowering the likelihood of osteoporosis, some forms of arthritis, heart attack, and kidney stones.

Keep in mind though that magnesium must be in the proper ratio to be used correctly. It’s important to be mindful of getting calcium from synthetic sources that are low in magnesium.

Vitamin K is also important for calcium synthesis, as it helps keep calcium in bones and out of arteries and muscles. Great sources include dark leafy greens, grass-fed butter, chicken livers and natto (a form of fermented soybeans).

Aside from getting enough of these nutrients, you may also want to consider limiting the amount of grains you eat. Grains are high in phytic acid, which can inhibit proper calcium uptake.

The bottom line: Calcium is ineffective without magnesium, vitamin K, and vitamin D. Eating too many grains can make calcium absorption more difficult as well.

Why Calcium Supplements Are Not the Answer

Since it seems so complicated to get enough calcium without dairy every day, you might be tempted (like I was) to try calcium supplements. However, it seems like that’s not a great choice. (Here’s why.)

Calcium supplements ups your risk of ingesting too much calcium. This can lead to increased risk of kidney stones, heart disease, and more.

As Chris Kresser explains, supplemental intake of calcium can be problematic, but dietary intake of calcium is considered safe and healthy:

Beyond being ineffective for bone health, calcium supplements are associated with some pretty serious health risks. Studies on the relationship between calcium and cardiovascular disease (CVD) suggest that dietary intake of calcium protects against heart disease, but supplemental calcium may increase the risk. A large study of 24,000 men and women aged 35–64 years published in the British Medical Journal (BMJ) in 2012 found that those who used calcium supplements had a 139% greater risk of heart attack during the 11-year study period, while intake of calcium from food did not increase the risk. A meta-analysis of studies involving more than 12,000 participants also published in BMJ found that calcium supplementation increases the risk of heart attack by 31%, stroke by 20% and death from all causes by 9%.

To be safe, calcium should be consumed from real food sources and not synthetic supplements or artificially fortified foods, like orange juice (where the synthetically added amount of calcium just settles to the bottom of the carton anyway).

Non-Dairy Sources of Calcium

While dairy is known to be a good source of calcium, there are many people who are lactose intolerant, allergic, or otherwise sensitive to dairy. In fact, it is estimated that 65% of the human population has a reduced ability to process dairy beyond infanthood.

Fortunately, there are lots of nutritious ways you can get calcium without dairy. Here are some of the best sources of calcium — and they’re all budget-friendly!

Bone Broth

Bone broth is a great source of calcium and many other minerals, and it’s so easy to make (but if you’re looking for a store-bought version, I recommend this one!) Broth made from healthy bones also contain amino acids that are great for other areas of your health, including digestion, skin, nervous system and joints.

Broth can be made from chicken, beef, lamb, bison, or even fish bones for just pennies a cup. Slow simmering the bones for long periods is best, as it allows the calcium and other minerals to dissolve into the water. As the Weston A Price Foundation puts it:

Science validates what our grandmothers knew. Rich homemade chicken broths help cure colds. Stock contains minerals in a form the body can absorb easily—not just calcium but also magnesium, phosphorus, silicon, sulphur and trace minerals. It contains the broken down material from cartilage and tendons–stuff like chondroitin sulphates and glucosamine, now sold as expensive supplements for arthritis and joint pain.

Fish With Bones

Fatty fish, especially those with the bones still intact, contain an impressive calcium content, and absorb easily. Canned fish like salmon and sardines are an easy and inexpensive way to get your fill, since the bones become soft and edible during the canning process. Just be sure to buy BPA-free tins and cans whenever possible!

I know, you might have just wrinkled your nose in disgust at the thought of eating whole sardines, but as Diane of Balanced Bites so perfectly put it:

Y’all need to put your big boy or girl pants on, get a tin of wild sardines, grab some sea salt and lemon or hot sauce, and DIG IN.

One six-ounce serving of canned wild salmon has over 110 milligrams of absorbable calcium and canned sardines rank about the same (or higher). Since these foods are also a good source of vitamin D, they enhance digestion of the calcium and make it more usable.

(If you’re curious, I get my salmon and other seafood from Vital Choice, and sardines from Thrive Market (the Thrive Market brand).

Dark, Leafy Greens

Dark leafy greens are another great dietary source of calcium and are probably your best bet if you’re vegan. However, not all leafy greens are created equal. Collard greens, turnip greens, bok choy, kale, and broccoli all ranked high as absorbable sources of calcium.

Dark leafy greens are also great sources of folate, vitamins A, C, E and K, and B-vitamins. Jonathan Bailor, author of The Calorie Myth, is fond of saying that if you make no other changes in your diet, you will see positive results just from adding a few extra servings of green leafy vegetables a day.

If you’re looking for dietary program to follow that doubles (or triples?) your veggie intake, I highly recommend the Wahls Diet Protocol because of her emphasis on vegetables en masse.

Getting Calcium… Without Dairy

Whether you’re allergic to dairy or just trying to avoid it for your own personal health reasons, there are plenty of ways you can get enough calcium without dairy. Supplementing is not necessary! Just make an effort to eat plenty of calcium-rich foods like broth, fish with bones, veggies (especially the green leafy kind), and other healthy sources of fats, protein, Probiotics as part of a varied diet.

While the above suggestions worked great for my family and me, keep in mind that I’m not a doctor and can’t tell you what your individual needs are. Be sure to check in with a health professional to get your nutrient levels checked and to discuss the best calcium sources for you.

    This is a real eye- opener for me. I have osteoarthritis and one of the causes is low calcium levels. I have been consuming Calcimax- P tablets for over 2 years now and I have found it quite effective as my bone pains have almost disappeared. This medicine contains almost all the ingredients you have mentioned which helps in absorption of calcium.
    A very well written article- it will change my outlook for selection of the food that I eat and also recommend to the patients that I treat.
    Hope to hear more from you in the near future. Adios.

    What are your thoughts about making a powder of eggshells and adding some
    Into your food each day for calcium?

    1. Katie Wells Avatar

      I’d personally rather eat sardines daily and get the omegas too, but I know people do that for the calcium.

  3. Tom Avatar

    Katie, that was one of the best blogs I’ve read on the topic of getting enough dietary calcium. Good information, easily digested – LOL.

    I would appreciate your input on Aubrey’s question, that is,

    Aubrey says:12.1.1
    What do you think about the Natural Calm magnesium powder with calcium?

    I have read from 2 or 3 sources that one should not mix calcium with magnesium (or with any other minerals). I take magnesium alone which is hard to find but I found it in the Natural Calm magnesium powder and take it before bed, and at least 2 hours from when having taken calcium (always including D3 and K2 with the calcium).

    For reasons having to do with unimaginable cruelty to farm animals, I am vegan. I have osteoporosis, but at 48 yo, was left pretty much confined to bed after a surgery gone wrong. Now at 59, I have bone loss and my spine creaks when I stretch to the left or right.

    What is your advice regarding mixing calcium with other minerals, but especially with magnesium? And when taking magnesium alone, should I include D3 and K2?

    please update your article, it is misleading when it states that too much Ca leads to those conditions. Actually the body adjusts to absorbing more or less depending on intake, if you are using supplemental forms in food etc.. you do not want to bounce from really high to really low……otherwise symptomology would occur, don’t expect the same results. Also the study that resulted in your information by med. doctors gave an incomplete impression because that was only for supplemental Ca that wasn’t combined with other nutrients in food or supplemental form that increase absorption/synergy so it resulted in deposits. You should correct your article, it appears to be about 4 years out of date.

    Thanks! I can’t take calcium supplements because they are so constipating and Tums give me terrible leg cramps while working out.

    My sister was (- and still is at 77) allergic to milk snd all cow dairy……however she was not sllergic to gosts milk …might be something to try

  8. Bean Avatar

    Regarding bone broth – the website that you shared shows 0% calcium for their bone broth even though it has bones in it! So it doesn’t appear to be a good source of calcium at all.

  9. Monica Avatar

    I read the nutritional labels and the bone broths have 0% calcium. It is NOT a good source of calcium.

  10. Nancy Avatar

    Can you clarify bone broth? 8oz has 2 gm of calcium (according To Sparkpeope.com tracker) I do use instead of water for cooking brown rice, soups and sauces so it might add up. Thanks

  11. Carolyn Avatar

    The nutritional info on the recommended bone broth in this article say 0% calcium so I’m also questioning it as a good source.

    Hi, WM!
    What bone-in salmon do you use? I’ve been using Wild planet, mainly bc it’s easiest to find, and I can sometimes get a good deal…but I have yet to see a reputable salmon in a can that’s still got its bones. I use Thrive, too, but still haven’t seen anything. Any suggestions?

  13. Billie Avatar

    Have you tried other bone broths? I’m obsessed with JPP appocathary. Full on flavor!

  14. peter Avatar

    Hello,

    Are you sure that your cheeses were really raw. It is hard to believe that someone can be allergic to raw milk – exactly the opposite – people are curing all kind of allergies with raw milk? This just does not make sense – also the reaction to raw protein should be much smaller if it exist. Bone broth is more difficult to digest than raw milk also raw milk have sulphur.

    Hi Katie,

    In your post, you claim that “[o]ur body actually needs 300-400 mg of calcium per day”, not the 1 [g] – 1.2 [g] RDA value. Do you have a source for this 300 – 400 [mg] range? I suspect that this is the WHO recommendation, but I would like to be sure. Thanks!

    1. jake Avatar

      The issue is that the research underlying both the USDA and the WHO calcium recommendations is very “squishy.” The Paleo Sherpa devoted 2 blog posts of a 3-part series on calcium to this issue. Search for “Paleo Sherpa” and “The calcium you keep” to find those two parts.

    Thank you for this article. I have been in a pickle over eating dairy for a few weeks now. I was dairy free for a couple years, and out of nowhere was craving it with intensity. I got good varieties of yogurt and kefir (cow and goat) and i can’t even explain how good and right it felt to eat dairy, literally out of NOWHERE. I never was much of a dairy person. A couple weeks later, I found out I am expecting (my first)! I want to do things correctly and have so much in my head against dairy (and there’s so much against raw dairy during pregnancy) that I’m confused!! Would you go with what your body is craving or focus on adding even more foods that provide a similar nutritional profile?
    On a side note, I do eat bone broth, lots of greens, etc. Also, I am experiencing no other food cravings.
    Your blog has provided so much guidance for me on my path to health, I really can’t thank you enough for all your research and experience you share.

      Congrats on your pregnancy 🙂

      I do try to follow my body when it comes to healthy foods during pregnancy and also to make sure I am consuming enough nutrients to nourish the baby. I’d check with a doc or midwife- a prenatal might also help. The dairy craving could be a calcium or Vitamin K thing, or any number of things, but I do also find I want dairy more when pregnant.

    My son as well as a friend’s had dairy allergies. Mine ate a very healthy diet occasionally including yogurt. My friend used goats milk, which is supposed to be much closer to human milk. Both our kids outgrew the allergy in elementary school.
