HelloPharmacist Scorecard of Biotin 10,000 mcg by Nova Nutritions
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains 2 active ingredients. Biotin is a B vitamin that helps your body convert food into energy and supports hair, skin, and nail health.
Calcium is a mineral essential for strong bones and teeth, and it plays a role in muscle and nerve function. The capsule also contains several inactive ingredients—gelatin, cellulose, silica, and vegetable magnesium stearate—which are fillers and binders that hold the supplement together.
Does it work?
Strong evidence
Biotin is likely effective for biotin deficiency, which can occur in people with certain genetic conditions or those taking medications that interfere with biotin absorption. For other uses, the evidence is less clear: biotin is rated possibly ineffective for multiple sclerosis and seborrheic dermatitis, and there isn't enough reliable evidence to rate it for alopecia areata (hair loss).
Calcium in this product is effective for treating low blood calcium (hypocalcemia) and likely effective for preventing and managing osteoporosis.
How safe is it?
Well-documented data
Biotin is generally well tolerated, even at fairly high doses, because your body removes excess amounts through urine. A small number of people taking very high doses have reported mild diarrhea.
There's one rare case report of a patient who developed a type of inflammation after taking biotin along with another supplement and heart medication, but whether biotin was actually responsible is unclear. Because this is a high-dose biotin product (10,000 mcg), discuss it with your doctor before starting, especially if you're taking other supplements or have any health concerns.
Calcium at recommended doses is generally safe, though higher amounts may cause belching, constipation, diarrhea, gas, or stomach upset. Very high calcium intake has been studied in connection with kidney stones and prostate cancer risk, though the research is mixed.
Pregnancy and lactation: Both biotin and calcium are likely safe during pregnancy and breastfeeding at normal amounts; however, confirm with your doctor that high-dose biotin is appropriate for you, and stick to recommended calcium intake.
Meds to double-check
Major interaction found
If you take dolutegravir (Tivicay) or elvitegravir (Vitekta) for HIV, or receive intravenous ceftriaxone (Rocephin), do not take this product without guidance from your doctor—calcium creates major interactions with these drugs. Also double-check before starting if you take raltegravir (Isentress), levothyroxine (Synthroid), sotalol (Betapace), diltiazem (Cardizem), or the psoriasis cream calcipotriene (Dovonex).

The bottom line
Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
This product is most clearly useful if you have a biotin deficiency, though the dose is quite high—check with your doctor first. The calcium here has major interactions with several HIV medications and one IV antibiotic, and moderate interactions with thyroid and heart medications, so if you take any prescriptions, search them on this page before you start.
Talk with your doctor or pharmacist about whether this product fits your personal health picture and medication list.

Biotin 10,000 mcg by Nova Nutritions Drug Interactions
HelloPharmacist Interaction Report
Biotin 10,000 mcg by Nova Nutritions contains two active ingredients: biotin and calcium.
Biotin itself has no documented interactions with medications. Calcium, however, has significant interactions with a number of drugs.
Read the full breakdown — every affected drug type, severity by severity
The most serious concerns are with HIV integrase inhibitors. Calcium reduces blood levels of dolutegravir (Tivicay) by nearly 40% and elvitegravir (Vitekta) through a process called chelation — where calcium binds to the drug and prevents absorption.
Take these medications either 2 hours before or 6 hours after calcium (2 hours after for elvitegravir). Calcium also interacts with the antibiotic ceftriaxone (Rocephin) when given intravenously; the two can form a dangerous precipitate in the lungs and kidneys, so avoid any intravenous calcium within 48 hours of IV ceftriaxone.
Calcium also moderately reduces levels or effectiveness of raltegravir (Isentress, an HIV drug), levothyroxine (Synthroid, for thyroid), the heart rhythm medication sotalol (Betapace), and the blood pressure drug diltiazem (Cardizem). It may also raise the risk of high calcium levels (hypercalcemia) if you're using calcipotriene (Dovonex), a vitamin D cream for psoriasis.
Altogether, these interactions span 168 individual medications. Use the search tool below to check your exact prescriptions before starting this product.

For each ingredient in Biotin 10,000 mcg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Calcium
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
