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 has 2 active ingredients: calcium, which supports bone health and is used to treat low blood calcium (hypocalcemia), kidney disease, and high potassium (hyperkalemia); and dehydroepiandrosterone (DHEA), a hormone precursor that your body makes naturally. The tablet also contains several inactive ingredients—microcrystalline cellulose, stearic acid, magnesium stearate, croscarmellose sodium, and silicon dioxide—which help bind and form the pill.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: DHEA supplementation for wellness.
  • We looked for evidence on: Adrenal insufficiency, Aging, Athletic performance, Cognitive function, Depression, Erectile dysfunction (ED) — and 4 related terms.
  • The strongest evidence on file: Dhea is rated "Possibly Effective" for Aging skin (Natural Medicines).
  • Also on file: Dhea is rated "Possibly Effective" for Depression, Infertility.
  • Also on file: Dhea is rated "Possibly Ineffective" for Muscle strength, Aging.

Calcium is effective for treating kidney disease, indigestion (dyspepsia), low blood calcium, high potassium, and is likely effective for osteoporosis. DHEA is likely effective for vaginal atrophy (thinning and dryness of vaginal tissue) and possibly effective for fertility, aging skin, and depression.

The strength of evidence varies; the product facts do not establish effectiveness for other uses.

The evidence, ingredient by ingredient Calcium Dhea

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 2 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 recommended doses, though high amounts can cause problems. The most common side effects are belching, constipation, diarrhea, bloating, and stomach upset.

Rare serious concerns include kidney stones and a skin condition called calciphylaxis. There is some epidemiological concern that very high calcium intake (over 1500–2000 mg daily) may be linked to increased prostate cancer risk and possibly cardiovascular disease, though research is mixed.

DHEA is a hormone and should be used only with medical guidance; the safety notes caution against it as a hormone supplement. Common side effects include acne (especially in women), headache, insomnia, mood changes, and nausea.

Women may experience masculinizing effects—deepening voice, increased body hair, irregular periods, oily skin, and reduced breast size. Men may experience aggression and breast growth.

Long-term DHEA use raises theoretical concern about cancer risk, and mania has been reported. DHEA is not safe in pregnancy and should be avoided while breastfeeding.

Dehydroepiandrosterone10 drug types · 776 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, DHEA might increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Human and laboratory research show that DHEA and DHEA-S can inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidepressant Drugs

Theoretically, DHEA might increase the risk of psychiatric adverse events when used with antidepressants.
In a human case report, the use of a selective serotonin reuptake inhibitor (SSRI) with DHEA caused a manic episode. Concern for this interaction may be greater in younger individuals with higher baseline DHEA levels.

Likelihood Possible Evidence D
Aromatase Inhibitors

Theoretically, DHEA might interfere with the clinical effects of aromatase inhibitors.
DHEA is a potent estrogen agonist, which may antagonize the anti-estrogen activity of aromatase inhibitors.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, DHEA might increase the levels of drugs metabolized by CYP3A4.
Some preliminary evidence shows that DHEA may inhibit CYP3A4; however, the clinical significance of this potential interaction is not known.

Likelihood Possible Evidence D
Fulvestrant (Faslodex)

Theoretically, DHEA might interfere with the anti-estrogen effects of fulvestrant.
DHEA is a potent estrogen agonist. Some research shows that it can overcome the estrogen receptor antagonist action of fulvestrant in estrogen-receptor positive cancer cells.

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, DHEA might interfere with the anti-estrogen effects of tamoxifen.
DHEA is a potent estrogen agonist. Some research shows that it can overcome the estrogen receptor antagonist activity of tamoxifen in estrogen-receptor positive cancer cells.

Likelihood Possible Evidence D
Triazolam (Halcion)

DHEA can increase blood levels of triazolam.
Administration of DHEA 200 mg daily for two weeks was shown to inhibit the cytochrome P450 3A4 (CYP3A4) metabolism of triazolam. This inhibition appears to be due to DHEA-S, rather than DHEA.

Likelihood Probable Evidence D
Tuberculosis Vaccine

DHEA might reduce the effectiveness of the tuberculosis vaccine.
Animal research shows that high doses of DHEA can reduce the efficacy of the Bacillus Calmette-Guérin (BCG) tuberculosis vaccine.

Likelihood Possible Evidence D
Estrogens

Theoretically, DHEA might increase the effects and adverse effects of estrogen therapy.
DHEA is a precursor to estrogen and androgen and is metabolized into those substances. In clinical research, DHEA supplements increase the levels of these hormones. Also, in clinical research, estrogen-progestin oral contraceptives and conjugated estrogens reduce blood levels of DHEA and DHEA-S. The clinical significance of these findings is unclear.

Likelihood Possible Evidence D
Testosterone

Theoretically, DHEA might increase the effects and side effects of testosterone therapy.
DHEA is a precursor to estrogen and androgen and is metabolized into those substances. In clinical research, DHEA supplements increase the levels of these hormones. The clinical significance of these findings is unclear.

Likelihood Possible Evidence D
Dehydroepiandrosterone full monograph & interactions

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.

DHEA 10 mg by Eurovital Nutraceuticals: Common Questions

Does DHEA 10 mg by Eurovital Nutraceuticals interact with any medications?
Yes. Based on its ingredients, DHEA 10 mg has a known interaction with 906 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?
DHEA 10 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.
Can I take this if I'm pregnant or breastfeeding?
DHEA is not safe in pregnancy and should be avoided while breastfeeding—the safety data advises against it. Calcium, on the other hand, is important in pregnancy and lactation; adequate amounts are recommended. Because this product contains DHEA, talk with your doctor or pharmacist before using it during pregnancy or nursing.
What are the most common side effects?
From calcium: belching, constipation, diarrhea, bloating, and stomach upset. From DHEA: acne (common in women), headache, insomnia, mood changes, and nausea. Women may also develop deeper voice, more body hair, irregular periods, and oily skin. Men may experience aggression and breast growth.
How far apart should I take this from my thyroid medication?
If you take levothyroxine (Synthroid or another brand), separate it from calcium by at least 4 hours. Calcium reduces how well your thyroid medication is absorbed, which can make it less effective.
Is DHEA actually a hormone?
Yes—DHEA (dehydroepiandrosterone) is a hormone precursor your body naturally produces. Because it's a hormone, it requires medical guidance and can cause hormonal side effects. It should not be used without talking to your doctor first.
What is this product meant to treat?
Calcium is effective for low blood calcium, indigestion, kidney disease, and high potassium, and is likely effective for osteoporosis. DHEA is likely effective for vaginal atrophy and possibly effective for fertility, aging skin, and depression. The product works for these purposes based on the evidence we hold.
