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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: vitamin D at 125 micrograms, which equals 5,000 international units (IU). Vitamin D is a fat-soluble nutrient your body needs to absorb calcium and maintain bone health.

The tablet also contains inactive ingredients—cellulose, modified cellulose gum, silica, stearic acid, and magnesium stearate—which are standard binders and fillers.

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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: bone, immune and cellular health.
  • We looked for evidence on: Fall prevention, Fractures, Muscle strength, Osteoarthritis, Osteomalacia, Corticosteroid-induced osteoporosis — and 4 related terms.
  • The strongest evidence on file: Vitamin D is rated "Effective" for Osteomalacia (Natural Medicines).
  • Also on file: Vitamin D is rated "Effective" for Renal osteodystrophy.
  • Also on file: Vitamin D is rated "Likely Effective" for Corticosteroid-induced osteoporosis.

Vitamin D at this dose is effective for treating rickets, osteomalacia (soft bones from vitamin D deficiency), renal osteodystrophy (bone disease linked to kidney failure), hypoparathyroidism (low parathyroid hormone), and familial hypophosphatemia (inherited low blood phosphate). These are established medical uses backed by clinical evidence.

If you're taking it for a different reason—say, general bone health or immune support—check the facts we hold for your specific use.

The evidence, ingredient by ingredient Vitamin D

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 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin D is well tolerated at recommended doses. However, very high doses taken over time can cause vitamin D toxicity, which raises blood calcium and can lead to symptoms like bone loss in adults and slowed growth in children.

The safety data notes that vitamin D is often used during pregnancy at recommended amounts but only under a doctor's guidance. At recommended doses it's generally acceptable while breastfeeding, though again check with your doctor before taking higher amounts.

In rare cases, excessive doses have caused serious effects including symptoms of high blood calcium, kidney problems, and anemia.

Formula

High potency vegetarian D3 for bone, immune & cellular health Vitamin D3 is a fat-soluble vitamin that helps maintain healthy bones by stimulating the absorption of calcium in the body. The body has the ability to make vitamin D naturally when exposed to sunlight. During the winter months, however, the body's vitamin D stores are low, increasing the risk of deficiency. Sunscreens can also block the body's ability to make vitamin D from sunlight. Vitamin D deficiency can contribute to accelerated bone loss and reduced calcium utilization. Recently, research shows higher intakes of vitamin D may support overall cellular health. Our vitamin D 125 mcg (5,000 IU) provides a vegetarian source of this key nutrient as a scored tablet-which means you can choose between a 125 mcg (5,000 IU) dose or breaking the scored tablet in half to consume 62.5 mcg (2,500 IU).

Vitamin D8 drug types · 715 drugs

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.

Likelihood Probable Evidence B
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.

Likelihood Probable Evidence B
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.

Likelihood Probable Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Probable Evidence B
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.

Likelihood Probable Evidence D
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.

Likelihood Probable Evidence B
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.

Vitamin D3 125 mcg (5,000 IU) by VitaScript: Common Questions

Does Vitamin D3 125 mcg (5,000 IU) by VitaScript interact with any medications?
Yes. Based on its ingredients, Vitamin D3 125 mcg (5,000 IU) has a known interaction with 715 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Vitamin D3 125 mcg (5,000 IU) contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 5,000 IU a safe dose?
At recommended doses, vitamin D is generally well tolerated. However, the safety data warns that very high doses taken over time can cause toxicity, and the recommended upper limit for adults is 4,000 IU daily. Your dose of 5,000 IU is close to that ceiling—use it only as prescribed by your doctor, and don't take extra without checking with them first.
Can I take this while pregnant or breastfeeding?
Vitamin D is often used during pregnancy and is generally acceptable while breastfeeding, both at recommended doses. However, the data advises using it only under your doctor's guidance if you're pregnant or considering higher amounts while nursing. Talk to your OB or pharmacist about what's right for you.
What is vitamin D supposed to do?
This product is effective for treating specific bone and mineral disorders: rickets, osteomalacia (soft bones from deficiency), renal osteodystrophy (kidney-related bone disease), hypoparathyroidism (low parathyroid hormone levels), and familial hypophosphatemia (inherited low blood phosphate). It helps your body absorb calcium and maintain bone strength in these conditions.
What are the side effects?
Vitamin D is well tolerated when taken at recommended doses. Serious side effects are rare. However, excessive doses can cause vitamin D toxicity, with symptoms including high blood calcium, bone loss, decreased growth in children, eye problems, and in severe cases, kidney damage and anemia.
Can this product reduce how well my other medications work?
Yes. Vitamin D might reduce absorption of atorvastatin (a cholesterol drug), and it may interfere with how your liver processes medications broken down by the CYP3A4 enzyme system. More importantly, if you take heart or blood pressure medications, high blood calcium from vitamin D can reduce their effectiveness. That's why you need to check your specific drugs before starting.
