Are you looking for vegan-friendly calcium sources to support your overall health? You’re in the right place! Calcium is crucial in maintaining healthy bones, muscle function, nerve transmission, and heart health.

Despite popular belief, vegans can quickly obtain sufficient calcium through various plant-based foods and supplements. In this blog post, we’ll explore the top vegan calcium sources and their benefits for your body – proving that dairy is one of many options for getting enough of this essential mineral.

Calcium and Its Importance for the Body

Calcium is an essential mineral that plays a crucial role in several bodily functions, such as maintaining strong bones and teeth, regulating muscle contraction, aiding nerve transmission, and supporting heart health.

In addition, calcium is involved in enzymatic functions, blood clotting, and maintaining normal blood pressure.

Calcium also contributes to the body’s alkaline balance by helping to maintain the body’s pH level, preventing acidification which can lead to health complications over time.

The body also uses calcium in cell division, which makes it integral for skin regeneration and healing.

Bone Health

Strong bones are crucial to overall well-being, especially as we age. Bone health is vital to maintaining our structure and protecting internal organs. The National Institute of Health states that almost all (98%) calcium in the body is stored in the bones, and the body uses the bones as a reservoir for, and source of, calcium to maintain calcium homeostasis.

Consuming adequate calcium helps mitigate the risk of osteoporosis, a disease characterized by low bone mass and deterioration of bone tissue.

Muscle Function

Calcium is crucial in supporting muscle function, as it is directly involved in muscle contraction. This essential mineral helps activate nerve impulses for our muscles to contract and relax properly.

Calcium is key for smooth muscle tissues found in organs like the heart and stomach, meaning an adequate intake of calcium helps in the normal functioning of the digestive and cardiovascular systems.

Nervous System

The nervous system plays a crucial role in regulating muscle contractions, an essential function that relies heavily on calcium. This vital mineral acts as a messenger by sending signals through nerve impulses and facilitating communication between the brain and muscles.

Calcium also aids the release of neurotransmitters, chemicals that transmit signals across cells, making it crucial for cognitive functions like memory and learning.

Heart Health

Calcium also plays a crucial role in maintaining a healthy heart. Adequate calcium intake helps the heart muscle contract and relax properly, allowing optimal blood flow throughout the body.

Moreover, calcium ions help transmit signals in the heart and other cells, critical for maintaining a regular heartbeat.

It’s also worth noting that some varieties of non-dairy yogurt are enhanced with calcium, providing another convenient option for additional dietary intake.

Vegan Calcium Supplements

Vegan calcium supplements, including standalone calcium supplements or combination supplements with vitamin D and other minerals, can be useful in ensuring adequate daily mineral intake for vegans.

They come in various forms like tablets, capsules, and chewable, making it easier for individuals to choose the type that best suits their preferences and lifestyle. Studies have shown that taking calcium supplements has been linked to decreased hypertension risk and cholesterol regulation.

However, talking to your healthcare provider before starting any dietary supplement is important to ensure they don’t interfere with your medications or cause adverse side effects. Moreover, too much calcium from supplements can lead to kidney stones or heart disease, so it’s crucial to stick to recommended dosages.

Vitamin D Supplements

Vitamin D supplements are essential for maintaining adequate calcium levels, especially for those following a vegan diet. As mentioned earlier, vitamin D promotes calcium absorption in the gut and helps maintain appropriate serum calcium and phosphate concentrations.

Vegans can struggle to find good sources of vitamin D as it is primarily found in animal products such as fish oil, egg yolks, and cheese. However, fortified plant-based alternatives like soy milk or almond milk can provide vitamin D, and other fortified foods like cereal and orange juice.

Additionally, exposure to sunlight produces Vitamin D naturally in the body making outdoor activities essential for optimal health. However, fortified foods or vitamin D supplements can be essential during months with less sunlight to prevent deficiencies and promote calcium absorption.

Consider also integrating mushrooms exposed to ultraviolet light into your diet, as they can produce vitamin D similarly to how our skin does.

How the Body Uses Calcium

The body absorbs calcium through the small intestine, which is broken down and passed into the bloodstream for use by the bones, muscles, nerves, and other organs.

Positive Absorption Interactions

Combining supplements may be worth considering if you’re a vegan looking to supplement your calcium intake. These supplements are typically taken together for their synergistic properties.

  • Calcium & Vitamin D: According to National Institutes of Health (NIH), “Optimal vitamin D levels are necessary to increase the efficiency of calcium absorption. Without adequate vitamin D, the body absorbs no more than 10% to 15% of dietary calcium. In the vitamin Dโ€“sufficient state, the intestinal calcium absorption increases to 30% to 40%.”
  • Calcium & Vitamin K: The National Institutes of Health (NIH) states, “Calcium is directly influenced by the amounts of vitamin K in the body as it affects processes, such as the calcification of blood vessels, maturation of sperm in the testes and bone formation.”

Negative Absorption Interactions

  • Proton Pump Inhibitors (PPIs): Often taken for heartburn, log-term use of these medications can interfere with calcium absorption. It’s essential to consult with your healthcare provider about any possible interactions.

Lifestyle Factors That Impact Calcium Needs

Calcium needs can vary depending on various lifestyle factors and stages of life. Physical activity level, age, pregnancy, and lactation influence the body’s calcium requirements. 

Alcohol Consumption

High consumption of caffeine and alcohol can interfere with calcium absorption and increase calcium excretion through urine. according to the National Institutes of Health (NIH), “Increased urinary calcium excretion was consistently found in the chronic alcohol drinkers.”


Zinc needs change throughout different stages of life. According to the National Institutes of Health (NIH):

  • Infants up to 6 months old: 200mg of calcium daily
  • Children 7 months – 12 months old: 260mg of calcium daily
  • Children 1 year – 3 years old: 700mg of calcium daily
  • Children 4 years – 8 years old: 1000mg of calcium daily
  • Children 9 – 13 years old: 1300mg of calcium daily
  • Adolescents 14 – 18 years old: 1300mg of calcium daily
  • Adults 19 – 50 years old: 1000mg of calcium daily
  • Adult Men 51 – 70 years old: 1000mg of calcium daily
  • Adult Women 51 – 70 years old: 1200mg of calcium daily
  • Adult 70+ years old: 1200mg of calcium daily

Pregnancy and Lactation

The body’s demand for zinc increases during pregnancy and lactation to support the growing baby’s development and breast milk production.

It’s important to note that these are general guidelines, and individual needs can vary. Always consult with a healthcare provider to determine your specific nutritional needs. If you follow a vegan diet, it’s crucial to ensure you consume enough zinc-rich foods or consider supplementation if necessary.

By being aware of these lifestyle factors and promoting good bone health, individuals can ensure they get the most out of their calcium-rich diets and supplements.

Tips for Meeting Calcium Needs on a Vegan Diet
