Ever since I was a child, the importance of getting enough calcium has been drilled into my head. I still remember the “Got Milk?” campaign of the 1990s, with celebrities sporting milk mustaches. However, for a long time, I never stopped to consider whether my calcium intake actually was adequate. A lot of Americans are in the same boat — many children and adults aren’t getting enough calcium through their diet.

Unfortunately, it can take a very long time for the consequences of inadequate calcium intake to become apparent. Blood calcium is tightly regulated by your body because it’s important for muscle and heart function. If you’re not getting enough calcium from your diet, your body will pull calcium from your bones to get what it needs. This is a major cause of bone loss.

“The simplest way to meet the general need is to focus on including three servings of a dairy product or fortified dairy alternative each day,” says Dru Rosales, RD, registered dietitian and owner of MindFuel Performance in Houston. “Remember that adolescents need an additional serving per day.” However, if it’s a struggle for you to meet this goal, or if you follow a vegan diet, you may want to consider supplementation.

Below, I’ve rounded up a number of calcium supplements worth your consideration. I’ve also compiled a list of calcium-rich foods for omnivores and vegans. (And surprise, milk isn’t the only food that’s high in calcium!) You’ll also find expert advice from dietitians who work with perimenopausal women and athletes, two populations for whom adequate calcium intake is extremely important.

These dietitians share how much calcium you need each day, how to get it, and some other ways to support bone health.

Dietary Supplements

Calcium dietary supplements
Everyday Health
Calcium supplements can help ensure that you’re getting enough calcium. If you’re in a group that’s at a higher risk of calcium inadequacy — for instance, you are postmenopausal, or you avoid dairy products — supplementation may be particularly important to ensure that you meet your calcium needs.

Momentous Calcium supplement

A Budget-Friendly Once-Daily Calcium Supplement

Momentous Calcium

Momentous Calcium provides 19 percent of the Daily Value (DV) for calcium in a single capsule, making it a convenient and affordable way to boost your calcium intake. It’s made with dicalcium malate, a form of supplemental calcium. I’ve tried these capsules myself — they’re about 1 inch long, but easy to swallow.

Additionally, Momentous is one of my favorite supplement brands because of its commitment to product quality and transparency. All of its products are third-party tested to ensure that the contents match the label, and it shares the lab results directly on its website.

Trace ionic calcium

An Easy and Convenient Liquid Calcium

Trace Minerals Ionic Calcium

Liquid calcium drops are an easy, convenient way to boost your calcium intake. A quarter teaspoon of this supplement provides 15 percent of the DV for calcium, and we found during our research that it is tasteless when mixed into beverages like coffee or juice.

Trace Minerals is a reputable brand of dietary supplements. I’ve tried several of their products, and I like that they are very transparent about ingredient sourcing and that all of their products are third-party tested.

Adora Dark Chocolate calcium supplement

Calcium and a Chocolatey Treat in One

Adora Rich Dark Chocolate Calcium Supplement

If you’ve tried chocolate calcium chews in the past, you may have found them unpleasant and chalky. But Adora’s a bit different — it’s a high-quality chocolate candy that also happens to be a calcium supplement. One serving provides a generous 39 percent of the DV for calcium.

Adora supplements are available in dark or milk chocolate, and they’re surprisingly affordable too. 

AlgaeCal stronger bones calcium

A Vegetarian Supplement With 16 Bone-Supporting Nutrients

AlgaeCal Plus

AlgaeCal is a complete bone health supplement that contains 56 percent of the DV for calcium, along with 15 other nutrients that are important for bone health, including magnesium and vitamin D.

The calcium in this supplement is naturally sourced from algae, making the supplement vegetarian-friendly. (Note: It is not vegan-friendly, however, because it contains vitamin D from lanolin, which is derived from sheep’s wool.)
AlgaeCal supplements are also third-party tested, and the ingredients and amounts used in AlgaeCal have been shown in an older study to support bone density.

Calcium-Rich Foods From Animal Sources

Calcium rich, animal-based foods
Everyday Health
If you’re an omnivorous eater, it’s more than possible to meet your daily calcium needs through diet alone, with a little bit of planning. Here are some of the most calcium-rich animal-based foods to consider including in your meal rotation regularly.
Chicken of the Sea alaskan pink salmon

A Convenient Calcium-Rich Protein Source

Chicken of the Sea Traditional Style Alaskan Pink Canned Salmon

Canned salmon is an unexpectedly great source of calcium — and one of my favorite shortcuts for an easy meal. “Traditional style” canned salmon contains bones, which is where the calcium comes from. One 3-ounce (oz) serving of this canned salmon provides 15 percent of the DV for calcium. Boneless canned salmon, unfortunately, is much lower in calcium.

Salmon cakes are incredibly easy to make with canned salmon and just a handful of staple ingredients, such as breadcrumbs, eggs, and mustard. Another of my favorite canned salmon meals is cooked pasta tossed in olive oil with raw baby spinach and cold canned salmon.

Wild Planet Wild Sardines in EVOO

A Tiny Tin Packed With Nutrients, Protein, and Umami

Wild Planet Sardines

I’m not a sardine person, but if you are, they are an excellent way to up your calcium intake. A 3-oz serving provides 15 percent of the DV for calcium. Wild Planet sardines are also non-GMO and sustainably caught using turtle-safe and dolphin-safe practices.

Sardines can add a savory, salty umami flavor to pizzas, salads, and pastas, and they’re an essential for homemade Caesar salad dressing. If you’re a seriously hardcore sardine fan, you may also enjoy them plain or on crackers. Like canned salmon, boneless sardine fillets will not provide a significant amount of calcium.

Siggi's icelandic yogurt

A Simple Snack to Boost Your Calcium

Siggi’s Icelandic Skyr Yogurt

Skyr is an Icelandic style of yogurt made from skim milk. It’s similar to Greek yogurt in that it’s extremely thick and creamy. Siggi’s is the most well-known brand of skyr yogurt available in most grocery stores. Like other yogurts, it can be eaten as a snack, as part of your breakfast, or incorporated into smoothies.

One serving of this yogurt provides 15 percent of the DV for calcium. Siggi’s is also available in several flavors, including plain, vanilla, strawberry, raspberry, and more. 

365 Whole Foods shredded parmesan cheese

The Most Calcium-Rich Cheese You Can Buy

365 Whole Foods Parmesan Cheese

Cheese is made from milk, so it naturally contains calcium. However, not all cheeses are equal in calcium content. Hard cheeses like Parmesan contain more calcium per gram than other types of cheese. One fourth of a cup of this Parmesan cheese from Whole Foods provides 25 percent of the DV for calcium.

While that may seem like a lot of Parmesan to eat at once, sprinkling a bit on your meals throughout the day will go a long way toward boosting your calcium intake. 

Organic Valley grassmilk

The Original ‘Good for Your Bones’ Beverage

Organic Valley Grassmilk 2% Reduced Fat Milk

Milk has a reputation for being the single best source of calcium in most people’s diets, for a good reason: One cup contains 20 percent of the DV for calcium. This milk from Organic Valley is organic and comes from grass-fed cows. It’s also fortified with vitamin D, another important nutrient for bone health.

One thing to note is that the shelf life of this milk is fairly short. The packaging says it should be consumed within six days of opening. The good thing, though? The inexpensive, nonorganic, store-brand milk at your local grocery store contains just as much calcium, if you’d rather get that instead.

Calcium-Rich Foods From Plant Sources

Calcium rich, plant-based foods
Everyday Health
Calcium isn’t just found in animal bones and dairy products — there’s a wealth of vegan-friendly calcium-rich foods available too. Here are some of my favorites.
BetterBody foods organic chia seeds

A One-Seed-Fits-All Shortcut to More Nutritious Meals

BetterBody Foods Organic Chia Seeds

Chia seeds are one of my favorite nutrition hacks. They’re rich in fiber, protein, and omega-3 fats, and you can add them to just about anything. I love chia seeds sprinkled on avocado toast or peanut butter toast for some extra crunch, and I add them to protein shakes for a fiber boost. Chia pudding is also an easy and delicious dessert that’s highly customizable.

Another great thing about chia seeds? One 2.5-tablespoon serving contains 15 percent of the DV for calcium. Feel free to sprinkle them on generously! (Just make sure to drink plenty of water, or the fiber content may bind you up.)

Wholesome Sweetners organic unsulphured molasses

Add Complex Sweetness to Sauces and Desserts

Wholesome Organic Blackstrap Molasses

Blackstrap molasses is a bit of an acquired taste, but it’s one of my favorite sweeteners. It has a really complex, unique flavor, and it’s not overbearingly sweet, compared with honey, maple syrup, or table sugar. Additionally, 1 tablespoon provides 10 percent of the DV for calcium. Molasses can also be used as a natural iron boost, since the same amount provides 15 percent of the DV for iron. This molasses from Wholesome is also certified organic and fair trade.

Here’s my recommendation for a calcium-boosting dessert: a chia seed pudding made with cow’s milk (or calcium-fortified plant milk) and sweetened with molasses.

Simply Orange Calcium juice

A Calcium Boost That Even Picky Kids Will Love

Simply Orange Juice With Calcium

Like milk, orange juice is commonly fortified with additional nutrients. However, not all orange juices are fortified with calcium, so it’s important to look for one that clearly states the calcium content on the label, if that’s what you’re looking for.

Simply Orange With Calcium is one of those options, providing 25 percent of the DV for calcium per cup. We like Simply Orange juice in my house. My kids will occasionally drink a cup with a meal, and I like flavoring my daily 64 oz of water with one cup of orange juice when we have some on hand.

Camellia cannellini beans

The Most Calcium-Rich, Versatile Bean

Camellia Dried Cannellini Beans

Beans are an unexpected way to meet your calcium needs, and the humble cannellini bean is one of the most calcium-rich types. Cannellini beans are one of my favorite beans because they’re very versatile. They can be used in soups, prepared as a side dish, or added to cold salads. (Side note: They’re a great option if you’re partaking in the “dense bean salad” trend.)

Cannellini beans provide 9 percent of the DV for calcium per serving, which is a quarter cup of dried beans. And if dried beans aren’t your thing? No worries, pick up a can of cannellini beans that are already cooked and ready to use. They contain the same amount of calcium.

Hodo organic extra firm tofu

For Pumping up the Protein (and Calcium) in Any Vegan Dish

Hodo Organic Extra Firm Tofu

Tofu is a classic source of protein for vegans, and a 3-oz serving provides 20 percent of the DV for calcium — the same as a cup of milk. This tofu from Hodo is organic and extra firm. I find that extra-firm tofu is the easiest to use and cook with.

Admittedly, I’m not a huge fan of tofu. However, I do like it when it’s sliced thin and cooked up crisp. I’ve personally tried Hodo tofu and can attest to its quality.

Silk Almond Milk

A Budget-Friendly Vegan Milk Alternative

Silk Unsweetened Almond Milk

Without fortification, plant-based milks are pretty low in calcium. However, several plant milks are now fortified with calcium and contain even more calcium than cow’s milk. One of these is Silk Almond Milk, which is inexpensive and can be found at most grocery stores.

One cup provides 35 percent of the DV for calcium. Even if you’re not following a plant-based diet, though, plant-based milks are delicious. For several years, Silk Almond Milk was my preferred milk for protein shakes and cereal. I’ve since started drinking cow’s milk again, but I still love the taste of almond milk.

Meal Planning and Tracking Tools

Apps for tracking and meal planning for calcium
Everyday Health
These digital tools can help you ensure that you’re planning calcium-rich meals and consuming adequate calcium each day. They both have helpful free versions, but the paid versions offer extra benefits and convenience.
Cronometer app

A Reliable Way to Track Your Calcium Intake

Cronometer Gold

If it’s extremely important to you to ensure that you’re getting enough calcium, a reliable food tracker is a necessity. I like Cronometer because its entire library of foods is based on verified or lab-analyzed information. Many other apps allow anyone to add foods, resulting in many entries that are incorrect or incomplete.

There’s a free version of Cronometer, which may be sufficient for you, but the Gold upgrade allows you more access to long-term data trends and insights about which foods are contributing the most to your intake of certain nutrients. I’ve used Cronometer extensively, and it’s my favorite food logging app.

Eat This Much meal planning app

A Tool to Help You Plan Calcium-Rich Meals

Eat This Much

Are you a meal planner? Eat This Much can help you generate healthy meal plans and provides options to target specific micronutrient goals, such as meeting your daily calcium needs.

The tool is free to use, but upgrading to Premium lets you create weekly meal plans rather than daily ones. It also generates automatic grocery lists for you and integrates with grocery delivery apps. It allows you to save and print your meal plans as well.

Why Is Calcium Important?

Calcium is a mineral that’s essential for our bodies to function properly. The most well-known role of calcium is in bone health. Calcium is a major component of the bone matrix in our bones and teeth. However, that’s not its only role. “While about 99 percent of the body’s calcium is stored in bones and teeth,” says Stacy Lofton, RD, founder of Table 12 Nutrition Consulting, “the remaining amount supports critical functions like muscle contraction, nerve signaling, heart function, and exercise performance.”

However, it’s really hard to detect that you’re not consuming enough calcium until your bones have already started to deteriorate. Tatiana Veléz-Burgos, RD, CSSD, a board-certified sports dietitian and official nutrition ambassador for Chobani, explains that calcium balance in the blood is very important. If you don’t consume enough calcium through your diet, she says, “the body starts pulling calcium from the bones, which leads to long-term weakening, increasing the risk of bone fractures, osteopenia, and osteoporosis.”

How Much Calcium Do We Need Each Day?

Calcium needs vary based on your age and stage of life. “Most adults need about 1,000 milligrams of calcium daily,” says Lofton. “Women over 50 generally need closer to 1,200 milligrams per day because bone breakdown increases after menopause.” Men over age 70 also need 1,200 milligrams per day to account for accelerated bone loss from aging.

“Teens will need more as they grow, ideally getting 1,300 milligrams per day,” adds Kendra Haire, RDN, owner of Radiant Nutrition and Wellness in Austin, Texas.

Who Might Need More Calcium?

Two key groups are particularly at risk of calcium inadequacy: postmenopausal women and people who don’t eat dairy products.

Menopause can lead to accelerated bone loss because the changes in hormone levels affect how the body absorbs calcium. This is why women over age 50 need 200 more milligrams of calcium per day than younger women.

Dairy foods are one of the richest sources of calcium, so if you avoid these foods (whether it’s because you follow a vegan diet or because of an allergy or intolerance), it’s important to seek out other calcium-rich foods. Fortunately, there are several dairy-free foods that are full of calcium.

Athletes may also need more calcium. “Especially during periods of intense training, low energy intake, or high sweat losses,” says Lofton. For athletes, it’s a good idea to work with a sports dietitian to determine the right level of calcium intake to meet your personal needs.

“Weight cycling and rapid weight loss can reduce bone density via muscle and bone loss,” adds Rosales. “It’s important to consult with a doctor to determine your risk and obtain a bone density scan, especially if you plan to lose weight.”

What Helps (and Hurts) Calcium Absorption?

Julie Pace, RDN, women’s health dietitian and founder of Core Nutrition Health & Wellness, explains that the calcium naturally available in foods is the easiest for the body to absorb, and all of the dietitians I spoke with recommended a “food first” approach. (For the record, I do too!)

However, if you do need to take a calcium supplement, there are a few things to consider that can help or hinder your body’s ability to absorb it. “I always recommend looking for a calcium supplement with vitamin D, which is needed for absorption,” says Rosales.

Haire adds, “It’s best to split the dose into no more than 500 milligrams twice a day for better absorption.”

Can You Take Too Much Calcium?

Yes, it is possible to consume too much calcium. Taking too much calcium from supplements can increase your risk of kidney stones and may be linked to an increased risk of heart disease. The tolerable upper intake level for calcium in adults is:

  • 19–50 Years Old 2,500 milligrams
  • 51–70 Years Old 2,000 milligrams
  • Over 70 Years Old 2,000 milligrams

What Are Other Ways to Support Bone Health?

There are some other evidence-based ways to support bone health as well.

Exercise, for example, is very important for maintaining bone density. Rosales recommends weight-bearing activities, including walking, running, dancing, or resistance training. “Aim for 30 to 40 minutes, three to four days per week,” she says.

Ensuring that you maintain a healthy, balanced lifestyle can go a long way toward ensuring that your bones stay strong too. “Bone health depends on a combination of healthy lifestyle factors, such as engaging in resistance training, getting adequate protein, maintaining a healthy body weight, avoiding smoking, and limiting alcohol consumption,” says Pace.
