9 Dietitian-Approved Calcium Supplements in 2025

The 9 Best Calcium Supplements, According to Dietitians

Calcium is the most abundant mineral in the human body, with 99 percent of it stored in your bones and teeth.

 As Bess Berger, RDN, owner of Nutrition by Bess in Teaneck, New Jersey, explains, “Calcium helps with an endless number of processes in our body. It’s probably most well known to help with bone support, such as bone formation and strength during childhood and the teen years, as well as preventing bone loss and osteoporosis during later years.”
Beyond bone health, calcium is essential for muscle contraction, nervous system communication, blood clot prevention, and regulating digestion, metabolism, and hormone release.

While many people get enough calcium from foods like dairy, fish with edible bones (like salmon or sardines), soybeans, and leafy green veggies, certain groups may need supplements to meet their needs. Depending on their age, children need 700 to 1,300 milligrams (mg) of calcium daily. All adults need 1,000 mg a day; women over 50 and men over 70 need 1,200 mg. It’s estimated that 49 percent of children ages 4 to 18 years and 39 percent of all individuals ages 4 and older don’t get enough. For reference, one glass of low-fat milk contains 300 mg of calcium, 8 ounces of yogurt contains around 415 mg, and half a cup of boiled spinach contains 123 grams.

Older adults, particularly women, those with dietary restrictions, and people with medical conditions that affect nutrient absorption, may benefit from calcium supplementation. Low levels of calcium are associated with a significant risk of developing osteopenia and osteoporosis, two conditions that cause weak or brittle bones and put you at risk of bone fractures and related complications.

As a dietitian, I get a lot of questions about calcium supplements — like which type is best and how much a person should take. Everyone’s needs differ, so we worked with six other dietitians to investigate this topic. We reviewed dozens of calcium supplements, looking at their ingredients, how trustworthy the brand is, and how much they cost. Here are our top recommendations, to help you make the best choice for your body.

Our Top Picks for Best Calcium Supplements

When to Consult Your Doctor

Everyday Health recommends speaking with your doctor before adding any supplement to your diet, to make sure it is safe and appropriate for your individual health needs.

Calcium supplements, while beneficial for some, can interfere with certain medications, such as thyroid medications, and affect the absorption and efficacy of these drugs.

Calcium supplements may not be safe for individuals with specific health issues like kidney disease or a history of kidney stones. Before starting calcium supplements, a conversation with your doctor can help ensure supplementation is right for you.

Best Calcium Powder

NOW Foods Calcium Citrate Pure Powder

$9.40 at Amazon
$14.99Now 37% Off

Pros

  • Easily dissolvable
  • Great for those who dislike pills
  • Third-party tested, cGMP facilities
  • Vegan, kosher, non-GMO

Cons

  • Less convenient than a capsule

This is our top choice for the best calcium powder, thanks to its simplicity and brand reputation. For those who can’t or don’t want to swallow a pill, NOW’s calcium citrate powder offers an affordable, quality choice. Powders are easy to mix into your beverage of choice and can give you more control over exactly how many milligrams you take.

The most common types of calcium you’ll see in supplements are carbonate and citrate. Calcium citrate, found in this product, can be easier to absorb and is less likely to cause digestive problems than calcium carbonate.

“I like this easily dissolvable calcium by NOW Foods, as it’s third-party tested, Current Good Manufacturing Practices (CGMP) certified, vegan, kosher, non-GMO, and affordable,” says Lisa Andrews, RD, owner of Sound Bites Nutrition in Cincinnati, Ohio. CGMP-certified means that a brand meets specific standards for quality and purity.

Third-party testing means NOW Foods hires independent labs to verify the purity and potency of its products.

“I’m also impressed that they are a founding partner of Vitamin Angels, a nonprofit that provides supplements to populations at risk for malnutrition,” Andrews adds.

Key Specs

  • Form: Powder
  • Serving size: 1½ teaspoons
  • Calcium per serving: 600 mg
  • Type of calcium: Calcium citrate
  • Other notable ingredients: None
  • Dietary considerations: Kosher, vegan, gluten-free, soy-free, nut-free

Best Organic Calcium

Garden of Life Organic Plant Calcium

$27.92 at Amazon
$36.95Now 24% Off

Pros

  • Organic algae-based calcium
  • Third-party tested and non-GMO certified
  • Vegan-friendly formula
  • Made with over 20 organic fruits and vegetables

Cons

  • Requires three tablets for full dose
  • Priciest on our list

For those seeking an organic, comprehensive approach to bone health, we recommend Garden of Life Organic Plant Calcium. If organic products are a priority for you, this is one of the only products on our list that is certified organic.

“Garden of Life Organic Plant Calcium is a standout choice for anyone prioritizing natural bone health,” says Alyssa Simpson, RDN, a digestive health dietitian in Phoenix, Arizona. “Made with over 20 organic fruits and vegetables, this USDA Organic and Non-GMO Project Verified supplement is a clean, whole-food option that is gentle on digestion while delivering essential nutrients for bone support,” she says.

She adds that she likes that this supplement sources its calcium from organic algae and combines it with plant-sourced magnesium, vegan vitamin D3, and vitamin K2 ─ all nutrients needed to support strong bones.

 For example, studies suggest that supplementing with both vitamin D and calcium can help increase bone mineral density in older adults.

Vitamin K2 helps direct calcium to the bones, rather than storing it in soft tissues or arteries (a risk factor for cardiovascular problems), and it may influence genes involved in bone breakdown and formation.

This product is the most expensive on our list, and some people may not want to spend the extra money if the organic label isn’t a priority. Also, three capsules can seem like a lot for people who don’t love swallowing pills, but we think the benefits are worth it.

Key Specs

  • Form: Tablets
  • Serving size: Three tablets
  • Calcium per serving: 800 mg
  • Other notable ingredients: Vitamin D, magnesium, vitamin K2
  • Dietary considerations: Kosher, organic, vegan

Best Calcium for Women Over 50

Jarrow Formulas BoneUp

$28.45 at Amazon
$43.99Now 35% Off

Pros

  • Optimal dose of calcium
  • Contains other important nutrients for bone health
  • Third-party tested, cGMP facilities
  • Gluten-free, non-GMO

Cons

  • Full dose requires taking two capsules three times a day
Jarrow Formulas BoneUp is one of the best calcium supplements for women over 50, offering a comprehensive blend of nutrients designed to support your bones. All adults need 1,000 mg of calcium daily until age 50, but after that, women’s needs jump to 1,200 mg (men’s needs increase to that amount after age 70) to reduce the risk of osteoporosis.

This product contains a patented form of calcium called StimuCal MicroCrystalline HydroxyApatite, a type of calcium from cow bones, plus other nutrients like vitamin D, vitamin K, and magnesium. As integrative dietitian Stephanie Dunne, RDN, founder of Nutrition Q.E.D. in St. Petersburg, Florida, explains, “Successful absorption and use of calcium by bones requires many other micronutrients as well. Jarrow Formulas BoneUp is an excellent choice for those looking to consume all the nutrients needed for bone health.” One study found that supplementing with BoneUp and exercise supported healthy bone markers in women.

Jarrow Formulas tests its ingredients for purity and potency, adhering to strict manufacturing standards and third-party testing.

A notable consideration here is that the recommended dosage is two capsules three times a day (two capsules provide 333 milligrams of calcium), totaling six capsules daily, which adds up. Taking more calcium at once doesn’t mean you absorb more. The amount you absorb from food and supplements depends on the type and total amount. Studies show that calcium absorption is highest with doses of 500 mg or less.

Splitting the dosages throughout the day helps you absorb what you take.

Key Specs

  • Form: Capsules
  • Serving size: Two capsules
  • Calcium per serving: 333.3 mg
  • Type of calcium: Microcrystalline hydroxyapatite
  • Other notable ingredients: Vitamin D, vitamin C, zinc, magnesium, copper, manganese, potassium, vitamin K2, boron
  • Dietary considerations: Gluten-free, wheat-free, soy-free, nut-free, dairy-free, egg-free, fish- and shellfish-free

Best Comprehensive Calcium for Bone Health

Thorne Advanced Bone Support

$25.65 at Amazon
$27Now 5% Off

Pros

  • Contains combination of calcium and other essential vitamins and minerals for bone health
  • Rigorous safety and testing standards
  • Free of gluten, dairy, and soy

Cons

  • Requires four capsules daily for full dose
We like Thorne Advanced Bone Support because it combines essential nutrients, including calcium, magnesium, vitamin D, and boron, all of which play crucial roles in bone health. This combination of ingredients is one of the most comprehensive on our list. This supplement contains a patented form of calcium called DimaCal, a type of dicalcium malate, which may be easier for your body to absorb and use while also providing more calcium per capsule.

The 1,000 international units (IU) of vitamin D helps your body absorb calcium more efficiently, while 3 mg of boron supports calcium metabolism and bone cell activity. “Research has linked [boron] to healthy bone mineral density,” explains Chelsea Rae Bourgeois, RDN, owner of Eat Well Gulf Coast in Bay St. Louis, Mississippi.

It also contains folate, vitamin B12, and vitamin B6 (which we didn’t see in many similar supplements), to help support healthy homocysteine levels in the blood.

Homocysteine is an amino acid made by the body. Some research suggests that high homocysteine levels may be a risk factor for low bone density (high levels are also linked to heart disease).

Thorne is known for its commitment to high-quality supplements, and each product goes through four rounds of in-house testing for identity, purity, potency, and stability. This product is also gluten-free, dairy-free, and soy-free. The recommended dosage is two capsules twice a day, which might seem like a lot, but it allows optimal nutrient intake throughout the day. Despite the dosage frequency, the benefits make it a top choice for comprehensive bone support.

Key Specs

  • Form: Capsules
  • Serving size: Two capsules
  • Calcium per serving: 300 mg
  • Type of calcium: DimaCal, dicalcium malate
  • Other notable ingredients: Vitamin D, vitamin B6, folate, vitamin B12, magnesium, and boron
  • Dietary considerations: Gluten-free, soy-free, dairy-free

Best Calcium With Vitamin D

Nature Made Calcium With D3

$10.79 at Amazon
$11.99Now 10% Off

Pros

  • Contains 400 IU of vitamin D
  • Softgels may be easier for some to swallow
  • USP-verified and third-party tested

Cons

  • Requires stomach acid for optimal absorption

While many calcium supplements include vitamin D, Nature Made Calcium With D3 stands out for its affordability, high-quality formulation, and optimal dosage of 500 mg of calcium per serving. The softgel form may be easier for some to swallow, and we also like that Nature Made products are verified by United States Pharmacopeia (USP), a third-party organization for confirming purity and potency.

Vitamin D plays a critical role in bone health because it helps your body absorb calcium effectively. Calcium absorption can be limited without sufficient vitamin D, so the two are often combined in supplements. Vitamin D is hard to obtain from food alone, as it is primarily produced in the skin through sunlight exposure. For adults under 70, the recommended dietary allowance of vitamin D is 600 IU, and 800 IU for those older than 70.

Nature Made contains 400 IU of vitamin D in one softgel, along with 500 mg of calcium, so you can easily use it to supplement food intake or take more to meet your needs if recommended by your doctor. Calcium carbonate is inexpensive, making this product an affordable option, but it may not be the best choice for those on medications that reduce stomach acid. You’ll want to take this supplement with a meal, since vitamin D is a fat-soluble vitamin and needs dietary fat for absorption.

Key Specs

  • Form: Softgels
  • Serving size: One softgel
  • Calcium per serving: 500 mg
  • Type of calcium: Calcium carbonate
  • Other notable ingredients: Vitamin D3
  • Dietary considerations: Gluten-free

Best Calcium-Only Supplement

Pure Encapsulations Calcium (Citrate)

$31 at Amazon

Pros

  • Provides well-absorbed calcium citrate without extra ingredients
  • Hypoallergenic and free of common allergens
  • NSF-certified for safety and quality standards

Cons

  • Requires separate vitamin D supplementation
  • Relatively low calcium content at 300 mg per serving

Pure Encapsulations Calcium (Citrate) is the go-to choice for a straightforward and effective calcium supplement. “It provides well-absorbed calcium citrate without any additional ingredients, making it ideal for those who want to customize their vitamin D intake separately,” says Simpson.

Pure Encapsulations is renowned for its commitment to purity and potency, setting high standards with rigorous third-party testing. “This supplement is also hypoallergenic, free from common allergens, and is manufactured in facilities that adhere to strict quality standards,” Simpson says.

Pure Encapsulations supplements are National Sanitation Foundation (NSF) certified, one of the most highly recognized independent, third-party certifications for supplement safety and standards.

With 300 mg of calcium per serving, this supplement is versatile: You can take it to fill any dietary gaps or adjust the dosage to meet higher calcium needs throughout the day.

Key Specs

  • Form: Capsules
  • Serving size: Two capsules
  • Calcium per serving: 300 mg
  • Type of calcium: Calcium citrate
  • Other notable ingredients: None
  • Dietary considerations: Free of wheat, nuts, gluten, vegan

Best Calcium Supplement for Kids

Renzo’s Hercules Calcium

$18.99 at Amazon
$19.99Now 5% Off

Pros

  • Convenient dissolvable/chewable tablet form
  • Includes other essential bone nutrients
  • Allergen-free, non-GMO, and sugar-free
  • Made in NSF-certified facility

Cons

  • Not all children need extra vitamin D or K2
  • Calcium phosphate may cause constipation

Renzo’s Hercules Calcium is our favorite choice for a children’s calcium supplement. This product features a simple formula that includes calcium, vitamin D3, and vitamin K2 for healthy bones and strong teeth. While not all children need calcium supplements, pediatric dietitian Jennifer House, RD, founder of First Step Nutrition in Calgary, Alberta, Canada, notes, “A calcium supplement may be required for children who don’t consume dairy or fortified alternatives regularly.”

The convenient sugar-free, non-GMO tablet is chewable or dissolvable, which is great for young children who may have difficulty swallowing pills. Children ages 1 to 3 need 700 mg of calcium per day, kids ages 4 to 8 need 1,000 mg, and those over 8 need 1,300 mg until they are 18.

This product contains 100 mg of calcium per tablet, making it an ideal choice to combine with food sources of calcium. “When it comes to supplements for kids, I’m a fan of products that don’t overdo it,” says Bourgeois. “As both a registered dietitian and a mom, I like to prioritize whole foods and let supplements bridge the gap.”

A downside is that this product contains calcium phosphate, which can cause constipation, though not everyone will experience this side effect.

Key Specs

  • Form: Chewable or dissolvable tablets
  • Serving size: One to two capsules, depending on age
  • Calcium per serving: 100 mg
  • Type of calcium: Calcium phosphate
  • Other notable ingredients: Vitamin D3 and vitamin K2
  • Dietary considerations: Free of top eight allergens, gluten-free, vegan

Best Calcium Gummy

MaryRuth’s Calcium Gummies

$25.95 at Amazon

Pros

  • Easy to take and delicious flavor
  • Sugar-free and allergen-free
  • Third-party tested and non-GMO

Cons

  • Lower calcium content per serving
  • Contains sugar alcohols that could cause minor gastrointestinal upset

MaryRuth’s Calcium Gummies are a standout choice for convenience and flavor. These gummies have a sugar-free peach, mango, and apricot flavor — but note that they are made for adults, so keep them away from children.

MaryRuth’s is known for its commitment to producing high-quality, non-GMO, allergen-free products with third-party testing for purity and content. Its gummies are free of common allergens like dairy, gluten, and nuts, while also being vegan-friendly.

These gummies contain only 200 mg of calcium (again, from calcium phosphate, so you also get some phosphorus). This amount of calcium is on the lower end, but this can be advantageous if you get some calcium from food and only need to supplement a small amount to meet daily recommendations.

These gummies contain the sugar alcohol erythritol, which may cause gastrointestinal upset in some individuals, though some research suggests that erythritol is better tolerated than other types of sugar alcohols.

 Overall, we love this option for adults who prefer not to take capsules ─ plus, the tasty flavor may help you remember to take it.

Key Specs

  • Form: Gummy
  • Serving size: Two gummies
  • Calcium per serving: 200 mg
  • Type of calcium: Calcium phosphate
  • Other notable ingredients: Phosphorus
  • Dietary considerations: Vegan, gluten-free

Best Budget-Friendly Calcium

Citracal Petites Calcium Citrate

$18.35 at Amazon

Pros

  • Affordable
  • Easy to absorb calcium citrate
  • Third-party tested

Cons

  • Capsule may be larger than expected

Citracal Petites Calcium Citrate is our favorite budget-friendly, effective calcium supplement. Priced at just around 5 cents per pill, it remains affordable even if you need to increase your dosage. Each serving provides 400 mg of calcium and 500 IU of vitamin D3, essential for maintaining strong, healthy bones. This product is third-party tested, ensuring safety and quality, and it uses calcium citrate for easier digestion and absorption.

Some users might find the capsule size larger than expected. While these pills are labeled as “petites,” this description might be a bit misleading for those anticipating tiny capsules. This is a straightforward and cost-effective supplement. It offers significant value, with 100 servings per bottle.

Key Specs

  • Form: Caplet
  • Serving size: Two caplets
  • Calcium per serving: 400 mg
  • Type of calcium: Calcium citrate
  • Other notable ingredients: Vitamin D
  • Dietary considerations: None listed

How We Chose the Best Calcium Supplements

I’m a registered dietitian with years of experience reviewing and using supplements. I worked with six other expert dietitians to ensure a comprehensive and transparent evaluation process. We examined numerous products, assessing ingredient quality, effectiveness, and dosage to ensure that the supplements meet standards for efficacy. We also scrutinized brand integrity, looking for companies that uphold high standards for transparency and safety.

Our dietitian experts included:

  • Lisa Andrews, RD
  • Jennifer House, RD
  • Alyssa Simpson, RDN
  • Stephanie Dunne, RDN
  • Bess Berger, RDN
  • Chelsea Rae Bourgeois, RDN

What to Look for When Buying Calcium Supplements

When purchasing a calcium supplement, consider the following factors:

  • Amount of calcium: Remember that more calcium isn’t better. Look for 500 mg of calcium or less per serving. “Consider the [dosage] and how it compares to your dietary intake through whole foods,” says Bourgeois. “And when in doubt, reach out to your registered dietitian for guidance.” And check other supplements like multivitamins that may add to your total daily intake.
  • Type of calcium: Certain forms like calcium citrate may be better absorbed or tolerated. “Calcium carbonate can sometimes cause bloating or gas, since it requires more stomach acid to break down, so calcium citrate may be a gentler option,” says Simpson.
  • Other ingredients: “Look for calcium supplements that include other compounds that increase the mineral’s absorption, such as vitamin D, vitamin K2, and magnesium,” says Bourgeois.
  • Prescription interactions: Consult a healthcare professional to understand potential interactions with medications, such as blood pressure meds or antibiotics. “Calcium can interfere with certain medications, like antibiotics and thyroid medications, and may also affect the absorption of iron and zinc,” Simpson says. “If you’re taking these, space them out for the best results.”
  • Quality: Consider choosing supplements that are third-party tested by independent organizations, such as USP or NSF, which test for contamination, and make sure that what is on the label matches what’s in the bottle. Some companies may also use internal testing, but if so, make sure that it’s a reputable brand.

Can Calcium Supplements Actually Benefit Your Health?

Calcium supplements can benefit anyone who doesn’t get enough in their diet. As mentioned above, nearly 40 percent of the population doesn’t get enough calcium. Calcium deficiency can lead to bone softening, lower bone strength, and increased risk of osteoporosis (a significant reason for frailty and loss of quality of life in older adults).

Calcium may also play a role in cancer, heart disease, preeclampsia, weight management, and metabolic syndrome, but more research is needed to fully understand these relationships.

“Calcium may help reduce blood pressure as well as the risk of colon cancer, though more studies are needed,” says Andrews.

“The first step is to determine if a person is deficient in a micronutrient through lab tests, dietary recall records, or symptom analysis,” says Dunne. “If a supplement is warranted, identifying the best form of the supplement and if any additional micronutrients are needed will yield the best results.”

Who Can Benefit From a Calcium Supplement?

Andrews says that people who don’t get enough calcium from their diet will most likely benefit from a calcium supplement. “Individuals that may benefit from a calcium supplement include those with lactose intolerance, an aversion or dislike of dairy products, or those following a vegan or vegetarian diet,” she explains.

“Calcium supplements may also be beneficial for post-menopausal women to help prevent osteoporosis or its progression,” she adds.

 It’s estimated that women lose around 1 percent of their bone mineral density per year after menopause, impacting bone health and increasing the risk of osteoporosis.

Who Should Not Take a Calcium Supplement?

If you get enough calcium from food and don’t have a medical condition that interferes with the digestion and absorption of calcium (like inflammatory bowel disease or celiac disease), you don’t necessarily need a calcium supplement.

Dunne says that certain individuals should skip supplements or check with their primary care provider before starting them. “People with cancer or cardiovascular disease and those with elevated blood calcium levels should not begin a calcium supplement without speaking to their healthcare provider,” she says.

Calcium can also interfere with the absorption of certain medications like levothyroxine (Synthroid) or iron supplements. If you take these supplements, check with your doctor or dietitian about spacing their intake away from any calcium supplementation.

What Is a Safe Dosage for Calcium Supplements?

“More isn’t always better with calcium,” says Simpson. “Aim for 1,000 to 1,200 mg daily from all sources, and keep supplement doses to 500 mg or less for best absorption.”

As mentioned earlier, calcium absorption maxes out at 500 mg, so Simpson suggests splitting doses throughout the day if you need more than that. Too much calcium can cause hypercalcemia, where blood calcium levels are higher than they should be. While rare, symptoms of hypercalcemia may include:

  • Poor muscle tone
  • Kidney insufficiency
  • High phosphorus
  • Constipation
  • Nausea
  • Weight loss
  • Fatigue
  • Frequent urination
  • Heart arrhythmias
  • Increased risk of cardiovascular disease mortality

If hypercalcemia is caused by supplements, it should normalize once you stop taking them.

FAQ

Are calcium supplements safe?

Calcium supplements are generally safe when taken as recommended. “As long as calcium supplements aren’t taken in excess, they're considered a safe supplement to use,” says Andrews. Taking too much could increase the risk of developing kidney stones (although getting enough calcium may actually prevent them). “Calcium taken in excess could increase the risk of soft tissue calcification, prostate cancer, and constipation,” she adds.

Almost 50 percent of the U.S. population doesn't not meet the recommended dietary calcium intake,” says House. She adds that children ages 9 to 18, vegans, people with certain health conditions that interfere with absorption, and people taking medications that cause calcium loss are all at risk of not getting enough.
According to House, calcium deficiency leads to loss of bone strength, which can cause osteoporosis in adults and rickets in children. “Rickets is when the cartilage doesn’t mineralize like it should when the child grows, and it can lead to irreversible changes in the structure of the skeleton,” she says.
Yes. “While individual needs vary, the established tolerable upper intake level for calcium is 2,500 mg for the average healthy adult,” says Bourgeois. “Consuming more than that may negatively affect heart health, muscle tone, renal function, and more. Excessive calcium intake may also interfere with certain medications, so it’s important to talk with your healthcare provider before starting new supplements.”
