100+ Calcium Rich Foods: Highest Calcium Foods Ranked by Weight & Serving Size
Written by Sascha Beck, BHSc (Nat), Dip Arom. Australian-qualified naturopath and
aromatherapist with a double major in nutrition and herbal medicine.
Discover simple food swaps and everyday additions to effortlessly increase your calcium intake. Compare more than 100 naturally calcium-rich foods by calcium content, serving size, calories and kilojoules to find the best foods for you.
Simple Ways to Effortlessly Increase Your Calcium Intake
Swap your usual cheese for a higher-calcium variety. Parmesan, Swiss and Jarlsberg cheeses contain almost three times as much calcium as some other cheeses. You may be able to significantly increase your calcium intake just by swapping the type of cheese you eat.
Choose freshly cooked whole sardines. Because they are eaten with their bones, freshly cooked sardines are one of the highest-calcium foods, providing considerably more calcium than many canned sardine products. If you buy canned sardines, compare the nutrition labels of different brands and varieties, as some contain considerably more calcium than others.
Don’t throw away the edible bones. Fish eaten with their soft edible bones—such as canned salmon, sardines and anchovies—contain much more calcium than boneless fish fillets because the bones are naturally rich in calcium.
Order oysters, pipis or periwinkles when you see them on the menu. These shellfish provide a surprisingly useful amount of calcium and are an easy way to increase your calcium intake when dining out.
Make pesto, chimichurri or salsa verde more often. These sauces contain generous amounts of fresh herbs, such as basil, which naturally contain calcium. Pesto provides even more calcium because it also contains Parmesan cheese, one of the richest sources of calcium. It’s an easy way to add extra calcium to pasta, vegetables, chicken, fish and sandwiches.
Cook your kale instead of eating it raw. Kale shrinks dramatically during cooking, making it much easier to eat a large, calcium-rich serving. A cup of cooked kale provides many times more calcium than a cup of raw kale because far more leaves fit into the same cup.
If you eat yoghurt, compare the nutrition labels before buying to find one that is high in calcium. It takes a little extra time, but you only need to do it once. Many yoghurts provide 300–450 mg of calcium per serving, making them one of the easiest ways to increase your calcium intake. When possible, choose a yoghurt with live probiotic cultures for the added benefit of probiotics.
Use almond meal when baking. Replace some of the flour in cakes, slices, muffins and pastry with almond meal. It’s an effortless way to increase the calcium content of your baking.
Don’t underestimate foods you eat every day. Bread may not top the calcium charts, but because many people eat it daily, it can make a meaningful contribution over the course of a week. The same principle applies to other foods you eat regularly.
Include tofu in your meals more often. Tofu is one of the best plant sources of calcium and can be added to stir-fries, curries, salads and soups. Different tofu products vary considerably in calcium content, so compare the nutrition labels to find one that is higher in calcium.
How to use this guide:
Rather than trying to change everything at once, browse through this guide over the next month or so and choose one new calcium-rich food to try or one simple food swap each week. Small changes can add up to a meaningful increase in your calcium intake over time.
Remember to look at the amount of calcium in a typical serving size, as calcium values per 100 g (3.5 oz) can sometimes be misleading. Before you begin, check how much calcium you should be getting each day in our Daily Calcium Requirements by Age & Life Stage (RDA/RDI) guide.
As a naturopath, I am very aware that many people struggle to work out whether they are getting enough calcium from food or whether they would benefit from a calcium tablet or other calcium supplements. I hope this guide helps you to get clearer on the answer to that question for yourself! If you’re unsure how much calcium you should be aiming for each day, see our How Much Calcium Per Day? Calcium RDA/RDI Guide.
One of the challenges when researching calcium rich foods is that the answer depends on how you measure them. A food may rank very highly by weight yet contribute very little calcium in the amount people normally eat. Interestingly common foods not usually thought of as a source of calcium can make a meaningful contributions simply because they are eaten regularly.
To help make sense of this, I have divided the article into two sections. The first section ranks foods high in calcium by 100 g (3.52 oz), which is the standard scientific method used in food composition databases. The second section ranks foods by a typical serving size, which is often more useful in everyday life. The second section has three serving sizes to choose from.
Both approaches have advantages and disadvantages. Looking at calcium by weight can help you identify the best calcium sources and compare similar foods. For example, some cheeses contain almost three times as much calcium as others, while different sardine products can vary considerably in calcium content. Looking at calcium by serving size is often more realistic, but serving sizes of different foods vary greatly between individuals and cultures.
Every food in the tables includes serving size information as a reality check. As you work through both sections, you should start to develop a feel for which foods genuinely help increase calcium intake and which foods only appear impressive at first glance. There is even a sweet surprise along the way!
I have reviewed and listed foods containing approximately 160 mg of calcium per 100 g (3.52 oz) or more and selected what I consider to be the most useful foods. I have intentionally excluded foods with added calcium because I wanted to focus on foods that naturally contain calcium. The amount of added calcium can vary considerably between products, and information about the source and quality of the added calcium is often difficult to find.
Calcium recommendations vary quite significantly between age groups, life stages such as pregnancy and breastfeeding, gender, and countries. See our Daily Calcium Requirements by Age & Life Stage – Calcium RDA/RDI guide for official calcium recommendations in the United States, Australia/New Zealand and Japan. In the United States, adults aged 19–50 years are generally advised to consume 1,000 mg of calcium per day, increasing to 1,200 mg for women aged 51+ years and adults over 71 years. Australia and New Zealand have similar recommendations for younger adults (1,000 mg/day), but recommend a higher intake of 1,300 mg/day for women over 51 years and adults over 70 years.
In contrast, Japan’s official recommendations are considerably lower, with adult men generally recommended around 750 mg/day and adult women around 670 mg/day depending on age. These differences are intriguing, possibly reflecting variations in body size, calcium absorption models, diet, lifestyle, fracture risk data, sunlight exposure, and traditional food patterns between countries.
Calcium recommendations vary significantly for children, teenagers during pregnancy and while breastfeeding.
Calcium Intro|Calcium Rich Foods by Weight | Calcium Rich Foods by Serving Size | A Sweet Surprise!
Calcium Rich Foods Ranked from LOWEST TO HIGHEST
by weight 100 g / 3.52 oz
21.
Calcium in Milk
It is worth noting that skim milk, reduced fat milk and full fat milk all contain similar amounts of calcium. Sheep’s milk provides only slightly more calcium than cow’s milk, but substantially more calories..
20.
Calcium in Fish and Seafood
Calcium levels vary considerably between different types of seafood. Fish that are eaten with their soft edible bones, such as canned salmon, sardines and anchovies, are often much higher in calcium than boneless fish fillets. Oysters can also provide significant amounts of calcium. Worcestershire sauce contains surprisingly high levels of calcium for a condiment and can make a useful contribution when added regularly to recipes. My Grandpa always kept a bottle on the dinner table!
Calcium in Bread
Bread is not usually considered one of the highest calcium foods. However, because many people eat bread regularly, it can make a useful contribution to overall calcium intake over the course of a day.
18.
Calcium in Tofu, Beans and Seeds
Tofu is one of the most significant vegan sources of calcium. One serving provides a substantial amount of calcium, although it does not provide all of the calcium needed for a day. Seeds such as flaxseed also contain calcium, but they are usually eaten in much smaller quantities.
Calcium in Fresh Herbs, Kale, Rocket and Lupin Beans
There is a big difference between raw and cooked leafy greens. As you will see later in this article, cooked kale provides considerably more calcium per serving because leafy greens shrink dramatically during cooking. It is much easier to eat a large serving of cooked kale than a large bowl of raw leaves. Fresh herbs are usually eaten in smaller quantities, but the calcium can still add up in herb-rich recipes. Pesto, salsa verde, chimichurri and other green sauces can contain surprisingly generous amounts of herbs. Some pesto recipes use around two cups of fresh basil, allowing herbs to make a modest but worthwhile contribution to overall calcium intake.
Cooked Kale vs Raw Kale – calcium levels
- Cooked Kale (1 Cup/ 130g/ 2.82 oz) – 400 mg of Calcium
- Raw Kale (1 Cup/ 16 g/ 0.56 oz) – 34 mg of Calcium
Calcium values for kale vary substantially between food composition databases. Differences may reflect variations in kale varieties, growing conditions, and analytical methods.
16.
Calcium in Yoghurt
Yoghurt is one of the easiest calcium-rich foods to include in the diet because a typical serving size provides a substantial amount of calcium. If possible, choose a yoghurt containing live probiotic cultures so that you benefit from both the calcium and the probiotics.
Calcium in Prawns, Oysters and Pipis
Most people think of shellfish as a source of protein, zinc, B12 and iron rather than calcium. However, prawns, oysters and pipis can make a significant contribution to daily calcium intake.
14.
Calcium in Acai, Maca and Gelatine
Acai, maca and gelatine rank surprisingly well when compared by weight. This is a good reminder that foods can look very impressive in a 100 g comparison, yet contribute only modest amounts of calcium in a typical serving. For this reason, it is worth considering both the 100 g rankings and the serving size information shown alongside each food. The Calcium in Foods by Serving Size rankings later in this article provide another useful perspective.
Calcium in Figs, Chocolate and Licorice
Figs, chocolate and licorice are not usually considered calcium-rich foods. However, they can still contribute meaningful amounts of calcium to the diet. If you eat the recommended serving size of 25 g (0.9 oz), you will not get a huge amount. But if it is one of those days and you happen to work your way through a block of milk chocolate or half a bag of licorice chocolate bullets, you will actually get a surprisingly significant amount of calcium! (Not that I am recommending it, of course.) Just acknowledging there are days like these!!
12.
Calcium in Almonds, Almond Meal and Almond Paste
Almonds can make a worthwhile contribution to calcium intake. Almond meal can disappear surprisingly quickly into cakes, slices, bliss balls and pastry bases, allowing larger amounts of almonds to be eaten than you might expect.
Calcium in Canned Salmon, Soya Products and Canned Milk
You may notice that tofu appears more than once in this article. Different tofu products can vary considerably in their calcium content. In this case, the cooked tofu contains noticeably more calcium than the earlier uncooked tofu entry. Many foods, including seafood, lose water during cooking. As a result, they often contain more calcium per 100 g after cooking because the nutrients become more concentrated. Canned salmon, soy products and canned milk are often purchased for reasons other than calcium, yet they can make a useful contribution to overall calcium intake.
10.
Calcium in Fresh Herbs, Kale, Nori and Grape Vine Leaves
Although fresh herbs, nori and grape vine leaves rank highly by weight, the usual serving sizes of these foods are quite small. While fresh herbs are usually eaten in small amounts, the calcium can add up in herb-rich recipes such as pesto, chimichurri, salsa verde, tabbouleh, stuffing and herb-based sauces. Cooked kale is the standout food in this section. Because kale shrinks dramatically during cooking, it is easy to consume enough in a single serving to obtain a significant amount of calcium.
Calcium in Pepper, Wattle Seeds, Green Tea, Cardamom and Tahini
Pepper, cardamom and wattle seed can look impressive in a 100 g comparison, but most people only use small amounts at a time. Tahini is the standout food in this section because it is often eaten in significant amounts in foods such as hummus, dressings and dips, allowing it to make a much more meaningful contribution to calcium intake. Wattle seed is an emerging Australian Bush Tucker food sourced from several Acacia species, including Acacia victoriae, a beautiful tree with tiny yellow pom-pom flowers.
8.
Calcium in Fish Paste, Periwinkles and Whey Protein Powder
Periwinkles are one of the most surprising foods in this section. They provide a substantial amount of calcium while being exceptionally low in calories. They are a traditional food in many parts of the world, including Ireland, Scotland, France, Spain, Portugal, Morocco, Ghana, Nigeria, China, Japan, South Korea and Vietnam. Fish paste is widely used in Asian cuisine. Whey protein powder is usually purchased for its protein content, but it also provides a useful dose of calcium.
Calcium in Chia Seeds, Dried Spices and Curry Powder
Dried herbs, spices and curry powders often look spectacular in nutrient tables because removing the water concentrates the minerals. The challenge is that most people only eat small amounts. Chia seeds are a little different. A chia pudding made with several tablespoons of chia seeds can provide a meaningful amount of calcium, and chia can also be stirred into soups, stews, rice dishes and baking.
6.
Calcium in Cheese
You may notice that cheese appears in several different sections of this article. This is because the calcium content of cheese varies considerably between varieties. Some cheeses contain more than three times as much calcium as others, which is why they are spread throughout the rankings rather than grouped together. If you are actively trying to increase your calcium intake, swapping from lower-calcium cheeses to higher-calcium cheeses can make a surprisingly big difference.
Cheeses High in Calcium
Calcium in Cheese – 100 g / 3.52 oz
- Parmesan / Swiss / Jarlsberg – 933 mg – 970 mg
- Natural Cheddar – 760 mg
- Processed Cheddar – 588 mg
- Reduced-Fat Fetta – 517 mg
- Regular Fetta – 315 mg
4.
Calcium in Cinnamon, Cumin and Coriander Seeds
Although cinnamon, cumin and coriander seeds are typically used in small amounts, recipes such as curries, tagines, chilli, dukkah, spice blends and baked goods can contain surprisingly generous quantities. Over time, these ingredients can make a modest contribution to calcium intake.
Calcium in Sardines – fresh and canned
Sardines are one of the most concentrated sources of calcium in this article because their soft edible bones are usually eaten. However, not all sardine products are the same. As the chart below shows in a way that is easy to take in visually, the calcium content can vary considerably depending on the type of sardine and how it is prepared. One surprising finding was that fresh home-cooked sardines contained approximately two to almost three times as much calcium as some tinned sardine products, even after accounting for the water or oil contained in the tin. If you look at the Typical Serving column, I have included the amount of actual sardines contained in various tins. This information can usually be found on the tin itself or in the nutritional information provided on supermarket websites.
Calcium in 100 g / 3.52 oz of sardines
- Fresh Cooked Sardines – 853 mg of calcium
- Raw Sardines – 725 mg of calcium
- Canned Sardines in Water (Drained) – 679 mg of calcium
- Canned Sardines in Tomato Sauce (Undrained) – 455 mg of calcium
- Canned Sardines in Oil (Drained) – 381 mg of calcium
- Canned Sardines in Oil (Undrained) – 302 mg
2.
Calcium in Milk Powder and Cheeses Highest in Calcium
The calcium stars of the cheese world are dried grated Parmesan, fresh Parmesan, Swiss cheese and Jarlsberg cheese, both regular and reduced fat. Among the milk powders, skim cow’s milk powder and whole goat’s milk powder come out on top for calcium.
Calcium in Vegetable & Fruit Powder, Dried Herbs & Shrimp Paste
It is surprising to find that dried herbs have the highest levels of calcium by weight. However, once again, they are not foods that most people consume in large quantities. That said, if you add generous amounts of herbs to dishes such as za’atar, herb-crusted roasts or fish, traditional stuffings, salsa verde, pesto, and some traditional Bolognese or marinara sauces, they can make a worthwhile contribution to calcium intake.
One of the easiest ways to increase calcium intake from this section is to add a teaspoon of vegetable or fruit powder to a smoothie.
In Central and Eastern Europe, a variety of sweet pastries use surprisingly large amounts of poppy seeds. Examples include Hungarian poppy seed roll, poppy seed strudel, cakes and breads, all of which can provide meaningful amounts of calcium.
Shrimp paste is widely used throughout Asia in curries, fried rice dishes, vegetable stir-fries, regional dipping sauces, and traditional meat and vegetable stews.

Calcium Rich Foods Ranked by Serving Size
This section ranks foods according to the amount of calcium provided by a typical serving size. The ranking is based on the Option 1 serving size, while Option 2 and Option 3 provide alternative serving sizes for comparison. This approach often gives a more realistic picture of which foods are likely to make the greatest contribution to daily calcium intake. Kilojoule (kJ) and calorie (kcal) information is also provided, as foods with similar calcium levels can vary considerably in their energy content.
To compare the calcium in these foods with official intake targets, see our Calcium RDA/RDI tables.
