Calcium is an essential nutrient for strong bones and to maintain many essential functions in the body (1). 99 percent of calcium is found in the bones and teeth (2). You must have adequate calcium levels to maintain healthy teeth and bone structure and to sustain proper nerve functioning (3). Calcium intake largely depends on your age and sex (4). Older females often need to supplement with calcium, for example. However, recent research has suggested that calcium supplementation can do more harm than good (5, 6). A study in the National Institutes of Health (NIH) showed that they can increase the risk of heart disease (7). Make sure you speak with your doctor about your calcium levels before you start a supplement.
Calcium needs to be balanced with proper vitamin D, phosphorus, and many other essential nutrients and minerals in the body (8). It’s possible to get adequate calcium from a healthy and balanced diet. There are a plethora of foods that contain calcium, but some of these food varieties may surprise you.

They are also very high in vitamin K, phytonutrients, and protein, making them an excellent choice to eat daily.
Almonds are by far the highest calcium source among the nut family (13). Almonds are full of healthy fats, protein, Vitamin E, magnesium, and tons of calcium (14, 15). They’ve even been shown to improve blood sugar levels, lower cholesterol, and improve blood pressure (16, 17). Only 22 almonds contain 8% of the daily recommended allowance for calcium. For that reason, almonds make an excellent substitution for dairy milk. Many who are lactose intolerant or sensitive to dairy, can benefit from incorporating almond milk into their daily routine.
Almonds are great to snack on, or you can even buy them sliced and add them to your favorite breakfast. almonds go well in breakfast like oatmeal, cereals, and they make an excellent addition in smoothies.

Many types of fish are an excellent source of calcium. Some of these fish include salmon, shrimp, and sardines (26). Sardines contain the highest amount of calcium at 325 milligrams per 3 ounces. That number is better for sardines canned with bones. Although, sardines canned without bones still contain high amounts of calcium. Only 1 three-ounce can of shrimp contains 125 milligrams of calcium. Shellfish like these are also packed with heart-healthy omega-3 fatty acids, necessary for heart, brain, and overall health (27, 28).

The dairy food group contains some of the highest sources of calcium (52). The highest sources of dairy include ricotta cheese, plain low-fat yogurt, skim milk, goat cheese, mozzarella cheese, cheddar cheese, Greek yogurt, American cheese, feta, and cottage cheese (53, 54). Part-skim ricotta cheese has the highest amount of dairy at 335 milligrams for 4 ounces. Yogurt is a great, healthy source of calcium, probiotics (55), and it can easily be added to a daily routine. Cottage cheese is also a great cheese to eat more frequently as it’s not as high in fat (56).
The issue that arises with cheeses like cheddar and milk is the high-fat content. It may not be a suitable option daily for those who struggle with excess weight or those who have a very slow metabolism. Cheese and some dairy are also extremely addictive because they have high concentrations of casein (57). When digested, casein releases casomorphins, which are plant compounds that trigger dopamine in the brain (58). In other words, casein does the same thing that opioids do to the brain in regards to their addictive qualities. One thing you can do to avoid this is choosing a cheese that doesn’t have casein, like goat cheese, which is still an excellent source of calcium.
Summary: The dairy food group contains some of the highest calcium sources. Yogurt, skim milk, and ricotta, goat, mozzarella, cheddar, feta, and cottage cheeses are some of the highest. Ricotta contains the highest with 335 milligrams in 4 ounces. Purchase low-fat dairy options for optimal health, and try casein-free choices such as goat cheese to vary your intake.
9. Fortified Foods
There are tons of fortified foods you can easily find in any supermarket, online or in-store. Plenty of popular foods are fortified with calcium, like breakfast cereals, almond milk, rice milk, and soy milk. Some other foods include tofu, orange juice, and even many snacks. Healthier snacks are often the only ones fortified with calcium. It’s important to understand that just because certain foods are fortified with vitamins and minerals, such as calcium, it doesn’t necessarily make them healthy (59, 60).
They’re often not foods you should eat daily, because they usually come from a box. Boxed food is more heavily processed than other foods. Stick to the whole version of foods whenever you can. Also, make sure kids don’t have an excess amount of fortified foods like sugary breakfast cereals. Many popular kinds of cereal have more sugar in one serving than should be eaten in a whole day. Always read the labels on all your grocery items to make sure they’re healthy.
Summary: Many foods are fortified with calcium, including breakfast cereals, tofu, orange juice, and almond, rice, or soy milks. Many of these more processed foods contain calcium, but may not be the healthiest choice. Check the food labels and make sure they aren’t full of added sugar or fat.
Calcium is necessary for optimal functioning in the body, but it can be easily overdone. This nutrient is crucial in combination with many others, so a balanced diet is the best way to go.
Here’s one example. Vitamin D, which is a hormone, plays a large role in maintaining optimal calcium levels, too (61). Without adequate vitamin D levels, it’s impossible to get enough calcium into the body.
Calcium supplements can be helpful, but only when monitored by your doctor, as it can be easy to take too much. Too much calcium can increase the chances of heart disease and even stroke. (62) Be sure to speak with your doctor if you think you might be low in calcium. And make sure you monitor how much you need based on where you are in your life. The dietary requirement for women and men of certain ages varies greatly.
