Calcium is an essential mineral vital for maintaining strong bones and teeth, supporting muscle function, nerve transmission, and blood clotting. Ensuring adequate calcium intake is crucial for overall health, and incorporating calcium-rich foods into your diet is the most effective way to meet your daily requirements. This guide highlights some of the top food sources of calcium, helping you make informed choices to boost your nutritional intake.
Dairy and Fortified Soy Alternatives: Calcium Powerhouses
Dairy products are well-known for their high calcium content. A small 4-ounce serving of plain, nonfat yogurt provides a substantial 244mg of calcium, making it an excellent choice. Low-fat plain yogurt is also a great source, offering 224mg of calcium in the same portion size. Kefir, a drinkable yogurt, delivers 159mg of calcium per half cup, while low-fat milk and unsweetened soy beverage (soy milk) provide around 153mg and 151mg of calcium respectively, also in half-cup servings. Even fat-free milk (skim milk) offers a significant 149mg of calcium per half cup. Buttermilk and Greek yogurt (both plain, low fat and nonfat varieties) are also noteworthy dairy sources, contributing between 125mg to 142mg of calcium per 4-ounce serving. For cheese lovers, while the calcium content varies, some reduced, low, or fat-free cheeses can offer a good amount of calcium in a smaller portion.
Vegetables: Unsung Calcium Heroes
Beyond dairy, certain vegetables are surprisingly rich in calcium. Cooked lambsquarters tops the list, providing an impressive 232mg of calcium per half cup. Nettles, also cooked, are another excellent vegetable source with 214mg of calcium in the same serving size. Mustard spinach, amaranth leaves, and collard greens, when cooked, deliver between 134mg to 142mg of calcium per half cup, making them valuable additions to a calcium-rich diet. Spinach, nopales, taro root, turnip greens, bok choy, and jute also contribute meaningfully to your calcium intake, offering between 92mg to 123mg of calcium per half-cup cooked serving. Even kale, mustard greens, beet greens, pak choi, and dandelion greens provide a decent amount of calcium, ranging from 74mg to 89mg per half cup cooked.

Tofu, especially when prepared with calcium sulfate, is a notable non-dairy protein source of calcium, offering 217mg per quarter cup. Canned sardines are another good source, providing 108mg of calcium per ounce, thanks to their edible bones. Canned salmon, also with bones, contributes 60mg of calcium per ounce. Tahini (sesame butter or paste), while consumed in smaller quantities, offers 51mg of calcium per teaspoon. Fortified grapefruit and orange juices are also options, each providing 175mg of calcium per half cup.
