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.

Maxi D3-2000 is a single-ingredient supplement containing vitamin D3 (cholecalciferol), the active form of vitamin D your body produces in sunlight and uses to absorb calcium and support bone health. The tablet also contains inactive ingredients — dicalcium phosphate, microcrystalline cellulose, stearic acid, magnesium stearate, and several others — that serve as binders and fillers to form the tablet.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Vitamin D's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Total wellness.
  • We looked for evidence on: Fall prevention, Fractures, Muscle strength.
  • The closest evidence on file: Vitamin D is rated "Possibly Ineffective" for Fractures (Natural Medicines).
  • Also on file: Vitamin D is rated "Insufficient Reliable Evidence To Rate" for Muscle strength, Fall prevention.

Vitamin D3 is effective for treating deficiency diseases: rickets (a bone disease in children), osteomalacia (soft bones in adults), familial hypophosphatemia (a rare genetic disorder), renal osteodystrophy (bone disease from kidney failure), and hypoparathyroidism (low parathyroid hormone). The evidence we hold doesn't address whether this dose works for general bone health or prevention in people without these conditions.

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 generally well tolerated at recommended doses. However, very high doses taken over time can cause vitamin D toxicity (hypercalcemia) with symptoms like bone loss, kidney problems, and anemia.

In children, excess vitamin D can slow growth. Rare symptoms of toxicity include eye inflammation and light sensitivity.

Vitamin D is often used during pregnancy at recommended doses, but only under your doctor's guidance. For breastfeeding, recommended amounts are generally considered acceptable — check with your doctor if you're considering higher doses.

There isn't enough data on file to know whether doses above recommended amounts are safe in either situation.

Side effects, ingredient by ingredient Vitamin D

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Vitamin D.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications.
  • For scale: 716 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Maxi D3-2000, check with your pharmacist if you're on any heart rhythm drugs (verapamil, diltiazem, digoxin), thiazide diuretics (water pills), atorvastatin, calcipotriene cream, or any medication processed by your liver — especially if you're on higher doses of this supplement.

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 vitamin D3 supplement is for people diagnosed with vitamin D deficiency or certain bone diseases where high-dose vitamin D is prescribed. If you take heart rhythm medications, water pills, cholesterol drugs, or kidney medications, talk to your pharmacist before starting — several of those can interact.

Stick to recommended doses and don't assume more is better; very high doses over time carry real toxicity risks.

Each ingredient & the kinds of drugs it affects

For each ingredient in Maxi D3-2000 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 D38 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.

Maxi D3-2000 by Maxi Health: Common Questions

Does Maxi D3-2000 by Maxi Health interact with any medications?
Yes. Based on its ingredients, Maxi D3-2000 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?
Maxi D3-2000 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.
What is vitamin D3 and why would I take it?
Vitamin D3 is the active form of vitamin D. It's prescribed when you have a deficiency disease like rickets, osteomalacia, or renal osteodystrophy — conditions where your bones don't form or maintain properly. Your doctor orders a blood test to confirm you need it.
Can I take more than the recommended dose to get better results?
No. Very high doses over time can cause vitamin D toxicity, with symptoms like bone loss, anemia, and kidney problems. Stick to what your doctor prescribes and don't exceed the tolerable upper intake level of 4,000 IU daily unless your doctor tells you otherwise.
Is vitamin D safe during pregnancy?
Vitamin D is often used during pregnancy at recommended doses, but only under your doctor's guidance. There isn't enough data on file to know whether higher doses are safe, so talk with your doctor about what's right for you.
What are the side effects?
At recommended doses, vitamin D is well tolerated with few side effects. Excessive doses can cause hypercalcemia — high blood calcium — with symptoms like bone loss, anemia, and in rare cases eye inflammation or light sensitivity. Children taking too much may have slower growth.
Can I take this with my other medications?
It depends on what you're taking. Vitamin D interacts with heart rhythm drugs, water pills, cholesterol medication, and several others. Use the medication checker on this page with your exact drug names, or ask your pharmacist before you start.
