HelloPharmacist Scorecard of D3 1000 Chewable Natural Spearmint Flavor by Genestra Brands
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 one active ingredient: vitamin D (in a liquid form you chew). The inactive ingredients are purified water, cellulose, spearmint flavoring, xanthan gum, olive oil, stevia leaf extract, potassium sorbate, and citric acid.
It's a straightforward single-ingredient supplement — the rest is just what holds it together and flavors it.
Does it work?
Not established
Vitamin D at this dose is effective for several medical conditions: familial hypophosphatemia (a genetic disorder affecting phosphate balance), osteomalacia (soft bones from vitamin D deficiency), renal osteodystrophy (bone disease from kidney failure), rickets (childhood bone disease), and hypoparathyroidism (low parathyroid hormone). If you're taking it for general bone health or immune support, the evidence we hold doesn't speak to those uses — talk with your pharmacist or doctor about what the science actually shows for your reason.
How safe is it?
Well-documented data
Vitamin D is well tolerated at recommended doses, but very high doses over time can cause toxicity with symptoms of high blood calcium — including bone loss in adults and poor growth in children. Eye irritation and sensitivity to light have also been reported with excessive intake.
The safety notes say it's often used in pregnancy at recommended amounts, but only under your doctor's guidance. For breastfeeding, there isn't enough data on file to say either way — check with your doctor or pharmacist for personalized advice.
Meds to double-check
Moderate interaction found
Before starting this product, check with your pharmacist if you take thiazide diuretics (water pills for blood pressure), digoxin or other heart medications like verapamil or diltiazem, atorvastatin or other cholesterol drugs, or calcipotriene (a vitamin D-like cream for psoriasis). Altogether, these interactions span 705 individual medications.
Use the interaction tool on this page with your exact prescriptions.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
This 1000 IU dose of vitamin D is appropriate if your doctor prescribed it for rickets, osteomalacia, or other bone and mineral disorders, or if you're supplementing a documented deficiency. If you take a water pill, heart medication, cholesterol drug, or anything metabolized by your liver, run it through the interaction checker on this page before you start — and stick to the 4000 IU daily limit if you're on digoxin or thiazide diuretics.
Talk to your pharmacist about your specific situation.

D3 1000 Chewable Natural Spearmint Flavor by Genestra Brands Drug Interactions
HelloPharmacist Interaction Report
Genestra Brands D3 1000 Chewable does interact with several medications, all related to its single active ingredient, vitamin D.
The most serious concern is with thiazide diuretics (a class of water pills), digoxin (a heart medication), and calcium-related drugs like calcipotriene — all rated Moderate severity. At high doses, vitamin D can raise your blood calcium level (hypercalcemia), which these drugs either worsen or can't handle well.
If you take a thiazide diuretic or digoxin, the product advises staying below 4000 IU daily and checking your blood calcium with your doctor.
Read the full breakdown — every affected drug type, severity by severity
Vitamin D also affects how your body absorbs other medications. It may reduce levels of atorvastatin (a cholesterol drug) by up to 55% in one small study, though cholesterol numbers didn't clearly suffer in that trial.
It can interfere with verapamil and diltiazem (heart rhythm medications), and theoretically increase aluminum absorption in people with kidney disease. Additionally, vitamin D might induce enzymes (CYP3A4) that speed up how your liver clears a large number of other medications — a Minor-severity concern.
Altogether, these interactions span 705 individual medications. Use the interaction checker below with your exact prescriptions before starting this product.

For each ingredient in D3 1000 Chewable Natural Spearmint Flavor 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.
Vitamin D
Aluminum
Vitamin D might increase aluminum absorption and toxicity, but this has only been reported in people with renal failure.
The protein that transports calcium across the intestinal wall can also bind and transport aluminum. This protein is stimulated by vitamin D, which may therefore increase aluminum absorption. This mechanism may contribute to increased aluminum levels and toxicity in people with renal failure, when they take vitamin D and aluminum-containing phosphate binders chronically.
Atorvastatin (Lipitor)
Vitamin D might reduce absorption of atorvastatin.
A small, low-quality clinical study shows that taking vitamin D reduces levels of atorvastatin and its active metabolites by up to 55%. However, while atorvastatin levels decreased, total cholesterol, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol levels did not substantially change. Atorvastatin is metabolized in the gut by CYP3A4 enzymes, and researchers theorized that vitamin D might induce CYP3A4, causing reduced levels of atorvastatin. However, this proposed mechanism was not specifically studied.
Calcipotriene (Dovonex)
Taking calcipotriene with vitamin D increases 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 vitamin D supplements might increase the risk of hypercalcemia.
Digoxin (Lanoxin)
Theoretically, hypercalcemia induced by high-dose vitamin D can increase the risk of arrhythmia from digoxin.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and digoxin concurrently.
Diltiazem (Cardizem, Others)
Theoretically, hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of diltiazem for arrhythmia.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically this could also occur with diltiazem. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and diltiazem concurrently.
Thiazide Diuretics
Theoretically, taking thiazide diuretics and high-dose vitamin D can increase the risk of hypercalcemia.
Thiazide diuretics decrease urinary calcium excretion, which could lead to hypercalcemia if vitamin D supplements are taken concurrently. This has been reported in people being treated with vitamin D for hypoparathyroidism, and also in elderly people with normal parathyroid function who were taking a thiazide, vitamin D, and calcium-containing antacids daily.
Verapamil (Calan, Others)
Hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of verapamil for arrhythmia.
Hypercalcemia due to high doses of vitamin D can reduce the effectiveness of verapamil in atrial fibrillation. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and verapamil concurrently.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Vitamin D might induce CYP3A4 enzymes and reduce the bioavailability of CYP3A4 substrates.
There is some concern that vitamin D might induce CYP3A4. In vitro research suggests that vitamin D induces CYP3A4 transcription. Additionally, observational research has found that increased UV light exposure and serum vitamin D levels are associated with decreased serum levels of CYP3A4 substrates such as tacrolimus and sirolimus, while no association between UV light exposure or vitamin D levels and levels of mycophenolic acid, a non-CYP3A4 substrate, was found. A small, low-quality clinical study shows that taking vitamin D reduces levels of the CYP3A4 substrate atorvastatin and its active metabolites by up to 55%; however, the clinical effects of atorvastatin were not reduced. While researchers theorized that vitamin D might induce CYP3A4, this proposed mechanism was not specifically studied.
