Top 20 Vegetables Highest in Calcium

Calcium is a mineral necessary for the growth and maintenance of strong bones, strong teeth, nerve signaling, muscle contraction, and secretion of certain hormones and enzymes. (1,2,3,4)

Calcium is an electrolyte, and a deficiency in calcium can lead to numbness in the fingers and toes, muscle cramps, convulsions, lethargy, loss of appetite, and abnormal heart rhythms. (5,6) A long-term calcium deficiency can lead to bone loss (osteopenia) and fragile bones (osteoporosis). (7) Vitamin D and Vitamin K are also important nutrients for preventing osteoporosis. (7)

Finding calcium in vegetables and fruits is a concern for vegans, people on a raw food diet, or people who simply want to eat a varied plant-based diet. While there is some evidence that oxalates in vegetables can hinder calcium absorption, they are still a good source of calcium. Kale shows similar calcium absorbability to that of milk, (8) and soybeans are also a good source. (9) For more, see the section on calcium absorption.

Vegetables high in calcium include collard greens, turnip greens, kale, mustard greens, beet greens, bok choy, okra, Swiss chard, and broccoli raab. The daily value (DV) for calcium is 1300mg. (10,11)

Note: Spinach and collard greens are high in both calcium and oxalates. An estimated 5% of the calcium is absorbed from spinach vs 40% from kale. (12,8) For this reason, spinach and collard greens are omitted from this curated list.

Below is a list of high-calcium vegetables by common serving size, for more see the list of high-calcium fruits and high-calcium foods.

How Much Calcium Do You Need Everyday?

The daily value (%DV) for Calcium is 1300mg and is a general target intended for most people. The Recommended Daily Allowance (RDA) shows specific targets by age and gender. The RDA for Calcium is between 800mg - 1300mg for most people.

What Affects Calcium Absorption?

  • Amount of Calcium In Your Body - When previous consumption of calcium is low, your body will naturally absorb more calcium to compensate for the difference. (13)
  • Vitamin D Intake - Vitamin D is critical for the absorption and regulation of calcium. (14,15) It can be found in foods or created by exposing skin to sunshine.
  • Age - Calcium absorption declines with age, particularly for women over 70 and men over 50. (16,17)
  • Pregnancy - Pregnant women absorb more calcium. (18)
  • Phytic and Oxalic Acid - The absorption of calcium from foods low in oxalates and phytic acid can be 20-40% as is true for milk and kale. (19,20) While oxalic acid and phytic acid does hinder calcium absorption it does not block it altogether. For example, 5% of the calcium in spinach is absorbed (21), while 30% of the calcium in soybeans is absorbed (22). Still avoiding foods high in phytic and oxalic acid will benefit calcium absorption. High amounts of oxalic acid are found in plant foods like spinach, collard greens, sweet potatoes, rhubarb, and beans. Phytic acid is found in whole bread and wheat bran.

Should I Take Calcium Supplements?

Unless prescribed by a doctor or health care provider calcium supplementation may do more harm than good. (23,24)

Major concerns with the over-consumption of calcium include gastrointestinal disease, kidney stones, and even heart disease. (23,24)

Only take calcium supplements if directed by a doctor or health care provider, or if you are sure you are consuming less than the recommended 1000-1200mg per day.

Further, calcium supplements will not be effective without adequate intake of vitamin D. (16,17)

Do vegans and vegetarians need to take calcium supplements?

Determining supplemental calcium needs for vegans and vegetarians is complex, and there is no clear evidence suggesting that vegetarians or vegans on a diet with a variety of foods need to supplement. (25,26) Further, calcium and vitamin D are frequently added to vegan milk substitutes like soymilk, almond milk, and coconut milk. As such, vegans and vegetarians do not need to supplement with calcium unless directed by a health care provider or are sure they are consuming less calcium.

What Other Foods and Nutrients Can Help Make My Bones Stronger?

Several nutrients are necessary for strong bones in addition to calcium. These include vitamin D, vitamin K, magnesium, phosphorus, protein, boron, silicon, and fluoride. (27,28,26)

Further, resistance exercises like weight lifting, and even tennis, can help maintain strong bones and encourage bone development or create "osteogenic effects". (29,30,31)

About Nutrient Targets

Setting targets can provide a guide to healthy eating.

Some of the most popular targets include:
  • Daily Value (%DV) - The daily value (%DV) is a general guideline for consumption that will prevent deficiency of a particular nutrient in most people. The %DV refers to the percentage of an amount that's found in a single serving of a food. It also accounts for absorption factors. It is set by the U.S. FDA.
  • Recommended Dietary Allowance (%RDA) - The RDA sets an average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all (97.5%) healthy individuals. It's more specific than the daily value, and varies by age and gender. The RDA is set by the US National Instutites of Health.
  • Reference Dietary Intake (%RDI) -The reference dietary intake is similar to the recommended daily allowance, but is specific to age and gender. The RDI for amino acids is set by the U.N. World Health Organization.
  • Adequate Intake (%AI) - This value is primarily used in reference to omega-3 and omega-6 fats. The Adequate Intake is set by the U.S. Institute of Medicine. Because there is less evidence to determine the ideal targets for consumption of these nutrients, the specific amount is considered to be less reliable. Using the term Adequate Intake, rather than one of the other terms, helps to emphasize that the ideal intake of that particular nutrient has not yet been scientifically determined.

See the Guide to Recommended Daily Intakes for more information.
