From our pharmacy team — supplement deep dive

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 contains two active ingredients: vitamin K (120 mcg) and vitamin D (2,000 IU). Vitamin K supports blood clotting and bone health, while vitamin D helps your body absorb calcium and supports bone and immune function.

The remaining ingredients are inactive—tapioca maltodextrin, a vegan capsule, dicalcium phosphate, and tapioca starch—which serve as fillers and capsule material.

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: Supports calcium absorption and bone heart health.
  • We looked for evidence on: Cardiovascular disease (CVD), Corticosteroid-induced osteoporosis, Dental caries, Fall prevention, Fractures, Heart failure — and 4 related terms.
  • The strongest evidence on file: Vitamin D is rated "Likely Effective" for Corticosteroid-induced osteoporosis (Natural Medicines).
  • Also on file: Vitamin D is rated "Possibly Effective" for Heart failure, Dental caries, Hyperparathyroidism-related bone loss.
  • Also on file: Vitamin K is rated "Possibly Effective" for Osteoporosis.

Vitamin K is effective for treating clotting disorders, including vitamin K deficiency and hemorrhagic disease (excessive bleeding). It's also possibly effective for osteoporosis.

Vitamin D is effective for rickets, osteomalacia (soft bones), hypoparathyroidism, and renal bone disease. The evidence we hold does not establish effectiveness for other uses not listed here.

The evidence, ingredient by ingredient Vitamin K 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 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.

Both vitamin K and vitamin D are generally well tolerated at recommended doses. Vitamin K taken by mouth may cause mild gastrointestinal side effects like nausea, abdominal pain, and diarrhea in some people.

Vitamin D is generally well tolerated, but very high doses over time can cause toxicity with symptoms of high blood calcium (hypercalcemia), including bone loss and, in children, slowed growth. Pregnancy and lactation safety data for vitamin K rates it as likely safe.

For vitamin D, the data shows it is likely safe in pregnancy and lactation, though there is also a rating of possibly unsafe in pregnancy—talk with your doctor about your individual situation and whether you need supplementation during pregnancy.

Side effects, ingredient by ingredient Vitamin K Vitamin D

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Vitamin D, Vitamin K.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; 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 this product, double-check with your doctor or pharmacist if you take warfarin or other blood thinners—vitamin K can directly weaken their effect and raise clot risk. Also check if you take thiazide diuretics (water pills), verapamil, diltiazem, or digoxin (heart medications), atorvastatin (a cholesterol drug), calcipotriene (psoriasis treatment), or any medications processed by the liver (CYP3A4 substrates), because vitamin D may reduce their effectiveness or increase side effects.

The dose here is 2,000 IU, but these interactions become more likely at higher vitamin D doses.

For each ingredient in K2 120 mcg + D3 2,000 IU Gold with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

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.

Likelihood Possible Evidence D

Vitamin K1 drug type · 2 drugs

Warfarin (Coumadin)

Vitamin K can antagonize and reverse the therapeutic effects of warfarin.
Vitamin K antagonizes the effects of warfarin. Excessive vitamin K intake, either from supplements or from changes in the diet, can reduce the anticoagulant effect of warfarin.

K2 120 mcg + D3 2,000 IU Gold by NutriGold: Common Questions

Does K2 120 mcg + D3 2,000 IU Gold by NutriGold interact with any medications?
Yes. Based on its ingredients, K2 120 mcg + D3 2,000 IU Gold has a known interaction with 715 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
K2 120 mcg + D3 2,000 IU Gold 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 on warfarin?
No—vitamin K in this product directly interferes with warfarin and can make it stop working to prevent clots. Talk with your doctor or pharmacist before taking any K supplement if you're on a blood thinner.
What side effects might I notice from the vitamin K?
Vitamin K taken by mouth is generally well tolerated, but a small number of people experience mild stomach upset, nausea, abdominal pain, or diarrhea. If these occur, they're usually mild.
Is it safe to take this during pregnancy?
Vitamin K is rated likely safe in pregnancy. Vitamin D shows mixed data—it's rated both likely safe and possibly unsafe in pregnancy depending on the circumstances. Talk with your doctor about whether this product or a different dose makes sense for you during pregnancy.
What's the difference between vitamin K and vitamin D?
Vitamin K helps your blood clot and supports bone health. Vitamin D helps your body absorb calcium and is essential for bone strength and immune function. This product gives you both.
Can this raise my calcium level too high?
The 2,000 IU of vitamin D here is within recommended limits and generally well tolerated. However, if you take water pills, heart medications, or psoriasis treatments, or if you take very high doses of vitamin D over time, high blood calcium becomes a risk. Check with your doctor if you're concerned about your calcium level or you're on one of those medications.
