What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: calcium and calcium D-glucarate. Calcium is a mineral essential for bone health, muscle function, and nerve signaling — your body uses it to build and maintain bone strength and to regulate how cells communicate.

Calcium D-glucarate is a compound derived from calcium and glucaric acid; it's being studied for potential effects on detoxification pathways in the body, though strong evidence of benefit in humans is limited. The product also contains inactive ingredients (cellulose, cellulose powder, and stearic acid) that serve as fillers and binders to hold the capsule together.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Hyperkalemia — rated "Effective" (Calcium) (Natural Medicines).
  • On file: Dyspepsia — rated "Effective" (Calcium) (Natural Medicines).
  • On file: Hypocalcemia — rated "Effective" (Calcium) (Natural Medicines).
  • On file: Kidney failure — rated "Effective" (Calcium) (Natural Medicines).
  • On file: Hyperparathyroidism — rated "Likely Effective" (Calcium) (Natural Medicines).

Calcium in this product is effective for treating low blood calcium (hypocalcemia), kidney failure, high potassium (hyperkalemia), and stomach upset (dyspepsia), and is likely effective for osteoporosis prevention and treatment. Calcium D-glucarate, however, has insufficient reliable evidence to rate its effectiveness for breast, prostate, or colorectal cancer.

The research to support its use for cancer prevention or treatment hasn't yet been established in the data we hold.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Calcium is generally well tolerated when taken at the recommended dose, though some people experience belching, constipation, diarrhea, flatgasiness, or stomach upset. Rare serious cases of kidney stones and a condition called calciphylaxis have been reported.

Some research raises concern that doses above 1500–2000 mg daily might increase the risk of prostate cancer or cardiovascular problems, though these findings remain debated. Calcium D-glucarate appears generally well tolerated in small studies, but long-term safety in humans hasn't been established.

The safety data advises against use in pregnancy, and safety while breastfeeding is unknown, so it's best avoided during lactation. Talk with your doctor or pharmacist about whether this product is right for your individual situation.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.

This product may help if you're low in calcium or have osteoporosis — that's where the evidence is strongest. The calcium D-glucarate ingredient is being studied but doesn't yet have proven benefits.

Because calcium interacts with quite a few medications, especially HIV drugs and levothyroxine, it's important to check your exact medications before starting. Talk with your doctor or pharmacist to make sure it's a fit for your health situation.

For each ingredient in Calcium D-Glucarate 500 mg with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Calcium18 drug types · 168 drugs

Ceftriaxone (Rocephin)

Co-administration of intravenous calcium and ceftriaxone can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys.
Avoid administering intravenous calcium in any form, such as parenteral nutrition or Lactated Ringers, within 48 hours of intravenous ceftriaxone. Case reports in neonates show that administering intravenous ceftriaxone and calcium can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys. In several cases, neonates have died as a result of this interaction. So far there are no reports in adults; however, there is still concern that this interaction might occur in adults.

Likelihood Probable Evidence D
Dolutegravir (Tivicay)

Calcium seems to reduce levels of dolutegravir.
Advise patients to take dolutegravir either 2 hours before or 6 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium carbonate 1200 mg concomitantly with dolutegravir 50 mg reduces plasma levels of dolutegravir by almost 40%. Calcium appears to decrease levels of dolutegravir through chelation.

Likelihood Probable Evidence B
Elvitegravir (Vitekta)

Calcium seems to reduce levels of elvitegravir.
Advise patients to take elvitegravir either 2 hours before or 2 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium along with elvitegravir can reduce blood levels of elvitegravir through chelation.

Likelihood Probable Evidence B
Aluminum

Calcium citrate might increase aluminum absorption and toxicity. Other types of calcium do not increase aluminum absorption.
Calcium citrate can increase the absorption of aluminum when taken with aluminum hydroxide. The increase in aluminum levels may become toxic, particularly in individuals with kidney disease. However, the effect of calcium citrate on aluminum absorption is due to the citrate anion rather than calcium cation. Calcium acetate does not appear to increase aluminum absorption.

Likelihood Possible Evidence B
Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Calcium might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption when taken in a fasting state.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide and calcium can be taken together if taken with food. However, if taken on an empty stomach, bictegravir/emtricitabine/tenofovir alafenamide should not be taken with, or 2 hours after, calcium containing products.

Likelihood Probable Evidence D
Bisphosphonates

Calcium reduces the absorption of bisphosphonates.
Advise patients to take bisphosphonates at least 30 minutes before calcium, but preferably at a different time of day. Calcium supplements decrease absorption of bisphosphonates.

Likelihood Probable Evidence C
Calcipotriene (Dovonex)

Taking calcipotriene with calcium might increase the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with calcium supplements might increase the risk of hypercalcemia.

Likelihood Possible Evidence B
Digoxin (Lanoxin)

Using intravenous calcium with digoxin might increase the risk of fatal cardiac arrhythmias.
Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. However, one retrospective analysis of clinical data suggests that intravenous calcium does not increase the risk of dysrhythmias or mortality in patients receiving digoxin.

Likelihood Possible Evidence B
Diltiazem (Cardizem, Others)

Theoretically, calcium may reduce the therapeutic effects of diltiazem.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, calcium might increase this risk of hypercalcemia and reduce the effectiveness of diltiazem.

Likelihood Probable Evidence D
Levothyroxine (Synthroid, Others)

Calcium seems to reduce the absorption and effectiveness of levothyroxine.
Advise patients to take levothyroxine and calcium supplements at least 4 hours apart. Calcium reduces levothyroxine absorption, probably by forming insoluble complexes. Calcium carbonate supplements reduce effectiveness of levothyroxine in patients with hypothyroidism.

Likelihood Probable Evidence B
Lithium

Theoretically, concomitant use of calcium and lithium may increase this risk of hypercalcemia.
Clinical research suggests that long-term use of lithium may cause hypercalcemia in 10% to 60% of patients. Theoretically, concomitant use of lithium and calcium supplements may further increase this risk.

Likelihood Possible Evidence B
Quinolone Antibiotics

Calcium seems to reduce the absorption of quinolone antibiotics.
Advise patients to take oral quinolones at least 2 hours before or 4-6 hours after calcium supplements or calcium-fortified foods. Taking calcium at the same time as oral quinolones can reduce quinolone absorption. Calcium binds to quinolones in the gut.

Likelihood Probable Evidence B
Raltegravir (Isentress)

Calcium may reduce levels of raltegravir.
Pharmacokinetic research shows that taking a single dose of calcium carbonate 3000 mg along with raltegravir 400 mg twice daily modestly decreases the mean area under the curve of raltegravir, but the decrease does not necessitate a dose adjustment of raltegravir. However, a case of elevated HIV-1 RNA levels and documented resistance to raltegravir has been reported for a patient taking calcium carbonate 1 gram three times daily plus vitamin D3 (cholecalciferol) 400 IU three times daily in combination with raltegravir 400 mg twice daily for 11 months. It is thought that calcium reduced raltegravir levels by chelation, leading to treatment failure.

Likelihood Possible Evidence B
Sotalol (Betapace)

Calcium seems to reduce the absorption of sotalol.
Advise patients to separate doses by at least 2 hours before or 4-6 hours after calcium. Calcium appears to reduce the absorption of sotalol, probably by forming insoluble complexes.

Likelihood Possible Evidence B
Tetracycline Antibiotics

Calcium seems to reduce the absorption of tetracycline antibiotics.
Advise patients to take oral tetracyclines at least 2 hours before, or 4-6 hours after calcium supplements. Taking calcium at the same time as oral tetracyclines can reduce tetracycline absorption. Calcium binds to tetracyclines in the gut.

Likelihood Probable Evidence C
Thiazide Diuretics

Taking calcium along with thiazides might increase the risk of hypercalcemia and renal failure.
Thiazides reduce calcium excretion by the kidneys. Using thiazides along with moderately large amounts of calcium carbonate increases the risk of milk-alkali syndrome (hypercalcemia, metabolic alkalosis, renal failure). Patients may need to have their serum calcium levels and/or parathyroid function monitored regularly.

Likelihood Probable Evidence C
Verapamil (Calan, Others)

Theoretically, calcium may reduce the therapeutic effects of verapamil.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, use of calcium supplements may increase this risk of hypercalcemia and reduce the effectiveness of verapamil.

Likelihood Probable Evidence D
Calcium Channel Blockers

Intravenous calcium may decrease the effects of calcium channel blockers; oral calcium is unlikely to have this effect.
Intravenous calcium is used to decrease the effects of calcium channel blockers in the management of overdose. Intravenous calcium gluconate has been used before intravenous verapamil (Isoptin) to prevent or reduce the hypotensive effects without affecting the antiarrhythmic effects. But there is no evidence that dietary or supplemental calcium when taken orally interacts with calcium channel blockers.

Likelihood Unlikely Evidence D

Calcium D-Glucarate3 drug types · 126 drugs

Alcohol (Ethanol)

Theoretically, concomitant use with alcohol might decrease calcium D-glucarate activity.
There is some evidence that urinary excretion of calcium D-glucarate metabolites increases in people consuming alcohol.

Likelihood Possible Evidence B
Glucuronidated Drugs

Theoretically, calcium D-glucarate might increase the clearance of drugs that undergo glucuronidation.
The calcium D-glucarate metabolite, D-glucaro-1,4-lactone, inhibits the enzyme beta-glucuronidase, reducing deconjugation of glucuronides in the intestine and thereby reducing reabsorption of the drugs.

Likelihood Possible Evidence B
Kanamycin

Theoretically, calcium D-glucarate may reduce plasma levels of kanamycin.
Calcium D-glucarate may increase the rate of kanamycin elimination, which may decrease its clinical and adverse effects.

Calcium D-Glucarate 500 mg by NOW: Common Questions

Does Calcium D-Glucarate 500 mg by NOW interact with any medications?
Yes. Based on its ingredients, Calcium D-Glucarate 500 mg has a known interaction with 288 medications, including 7 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Calcium D-Glucarate 500 mg contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is calcium safe to take while I'm pregnant or breastfeeding?
Calcium itself is likely safe in pregnancy at recommended doses — adequate calcium is important during pregnancy. However, the calcium D-glucarate in this product should be avoided during pregnancy because there isn't enough safety data. For breastfeeding, calcium needs can be met through recommended amounts, but calcium D-glucarate safety while nursing is unknown and it's best avoided. Talk with your doctor or pharmacist about what's right for your situation.
Can I take this if I'm on levothyroxine (Synthroid)?
Calcium can significantly reduce how your body absorbs levothyroxine, making it less effective. If you take levothyroxine, take it at least 4 hours apart from this supplement — either take your levothyroxine first, then wait 4 hours before taking calcium, or the other way around. Check with your doctor or pharmacist about the best timing for your doses.
What side effects does calcium cause?
Most people tolerate oral calcium well. The most common side effects are belching, constipation, diarrhea, bloating, and stomach upset. Serious side effects like kidney stones or calciphylaxis are rare. Very high doses — over 1500–2000 mg daily — raise theoretical concerns about prostate cancer and heart disease, though research is still debated.
Does this product work for cancer prevention?
The calcium D-glucarate in this product is being studied for breast, prostate, and colorectal cancer, but there isn't enough reliable evidence yet to say whether it works. Calcium itself isn't marketed for cancer prevention.
Will alcohol affect how this works?
If you drink alcohol regularly, the calcium D-glucarate ingredient may be less effective, because alcohol appears to increase how quickly your body clears it. If you consume alcohol often and take this product, mention that to your doctor or pharmacist.
What is calcium D-glucarate and why is it in here?
Calcium D-glucarate is a compound made from calcium and glucaric acid. It's included in supplements because it's thought to support the body's natural detoxification processes, particularly in the liver. However, strong evidence of benefit in people hasn't been established yet.
