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 8 of its 8 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

OSAplex MK-7 contains 8 ingredients, 5 of which are active: vitamin D3 (cholecalciferol), vitamin K2 (phylloquinone or menaquinone), calcium in three forms — MCHC (microcrystalline hydroxyapatite concentrate), microcrystalline hydroxyapatite, and elemental calcium — choline, and silicon. Phosphorus is also listed but we hold no interaction data for it.

The rest are inactive ingredients (fillers, binders, and capsule materials). This is a bone-support formula.

Vitamin D3 helps your body absorb calcium and maintain bone strength. Vitamin K2 plays a role in bone mineralization and blood clotting.

Calcium is the structural foundation of bone. Microcrystalline hydroxyapatite (MCHC) is a form of calcium that mimics bone mineral.

Choline and silicon round out the formula at smaller amounts.

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 overall bone health and strength.
  • We looked for evidence on: Fall prevention, Fractures, Corticosteroid-induced osteoporosis, Fetal bone mineralization, Child growth, Osteoporosis — and 2 related terms.
  • The strongest evidence on file: Calcium is rated "Likely Effective" for Corticosteroid-induced osteoporosis (Natural Medicines).
  • Also on file: Calcium is rated "Likely Effective" for Osteoporosis.
  • Also on file: Vitamin D is rated "Likely Effective" for Corticosteroid-induced osteoporosis.

Vitamin D3 is effective for rickets, osteomalacia (soft bones), renal osteodystrophy (bone disease from kidney failure), familial hypophosphatemia, and hypoparathyroidism (underactive parathyroid glands). Vitamin K2 is effective for vitamin K-dependent clotting factor deficiency and hypoprothrombinemia (low blood-clotting factors), and is possibly effective for osteoporosis.

Calcium (via MCHC, microcrystalline hydroxyapatite, and elemental calcium) is effective for hypocalcemia (low blood calcium), kidney failure complications, and indigestion; it's likely effective for osteoporosis. Silicon is possibly effective for osteoporosis.

Choline is rated as possibly ineffective for athletic performance and has insufficient evidence for cognitive decline, liver health, allergies, and Alzheimer disease. We hold no effectiveness data for phosphorus.

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin D3 is generally safe at recommended doses but can cause toxicity at very high doses over time, with symptoms including high blood calcium (hypercalcemia), low red blood cell count (anemia), and loss of kidney function (azotemia). Rare serious effects include eye inflammation and decreased growth in children.

It's likely safe in pregnancy at recommended amounts and likely safe while breastfeeding, though you should use it only under your doctor's guidance. Vitamin K2 is likely safe in pregnancy and lactation.

Oral calcium is well tolerated at recommended amounts but can rarely cause kidney stones or a serious skin condition called calciphylaxis. Very high daily calcium intake (over 1500–2000 mg) has been linked in some research to increased prostate cancer risk and cardiovascular disease, though other studies dispute this.

Calcium is likely safe in pregnancy and lactation at recommended amounts. Choline at recommended doses causes no significant side effects, but doses above 3.5 grams daily can cause fishy body odor, diarrhea, nausea, and vomiting.

It's likely safe in pregnancy and lactation when used appropriately. Silicon from food and most supplements is well tolerated, but high-dose or long-term safety isn't well studied.

During pregnancy and breastfeeding, there isn't enough safety data, so talk with your doctor first. Choline was rated as likely safe in both pregnancy and lactation.

Major identified

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

Why this rating?
  • 4 of the 5 matched ingredients can interact with medications — Choline, Calcium, 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; lithium.
  • For scale: 794 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 OSAplex MK-7, check with your doctor or pharmacist if you take warfarin (Coumadin) or any blood thinner — vitamin K2 can reverse its effect. If you're on the HIV drugs dolutegravir (Tivicay) or elvitegravir (Vitekta), or the antibiotic ceftriaxone (Rocephin), calcium in this product could significantly lower drug levels or cause serious harm.

Also flag thiazide diuretics, verapamil (Calan), diltiazem (Cardizem), digoxin (Lanoxin), or atorvastatin (Lipitor) — vitamin D3 or calcium can affect how they work. If you take levothyroxine (Synthroid) for thyroid disease or sotalol (Betapace) for heart rhythm, you'll want to space this product and your medication several hours apart.

No interactions are documented for the phosphorus in this product, as we hold no data for it.

Bone is composed of a calcium-based mineral complex and an organic material known as collagen. A somewhat flexible and fibrous protein, collagen appears to be a key factor in a bone's ability to withstand sudden impact. The quantity and health of collagen determines the bone's "toughness," while the mineral content determines its strength and stiffness.

Formula

OSAplex MK-7 is a comprehensive, convenient, and cost-effective dietary supplement that supports healthy bones, cartilage, and ligaments. Each packet provides the following: two capsules containing a combination of microcrystalline hydroxyapatite concentrate (MCHC) from Ossopan 1100, vitamin D3, and vitamin K2 along with one capsule of choline-stabilized orthosilicic acid (ch-OSA).

OSAplex MK-7 contains choline-stabilized orthosilicic acid, a well-absorbed form of silicon that has been clinically tested. Silicon-dependent enzymes link together single chains of amino acids to synthesize collagen fibers. The surfaces of these collagen fibers act as the binding sites for the MCHC. The more surface area available to the MCHC to bind to, the more flexible the bone. MCHC, a proprietary, standardized, and safe-source bone extract from the New Zealand bovine, contains a crystalline calcium and phosphorus matrix in the ideal physiological ration of 2:1, plus bioactive growth factors and type I collagen. As a source of calcium, MCHC contributes to the production and maintenance of bone structure, a function supported by vitamin D3 and K2. Amino acids, glycosaminoglycans, and a broad range of essential trace elements are also present. Combine ch-OSA and MCHC with significant levels of vitamins D3 and K2, and the result is a unique package that addresses quantity and quality of bone, and supports overall bone strength and health. Each packet contains: 2 Microcrystalline Hydroxyapatite concentrate with vitamin D3 and K2 capsules and 1 choline-stabilized orthosilicic acid capsule.

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.

Likelihood Possible Evidence D
Vitamin D3 full monograph & interactions

MCHC18 drug types · 168 drugs

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.

Likelihood Probable Evidence D
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.

Likelihood Probable Evidence B
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.

Likelihood Probable Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Probable Evidence D
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.

Likelihood Probable Evidence C
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Probable Evidence D
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.

Likelihood Probable Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Probable Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Probable Evidence C
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.

Likelihood Probable Evidence C
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.

Likelihood Probable Evidence D
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.

Likelihood Unlikely Evidence D
MCHC full monograph & interactions

Choline1 drug type · 16 drugs

Atropine

Theoretically, choline might decrease the effects of atropine in the brain.
Animal research shows that administering choline one hour before administering atropine can attenuate atropine-induced decreases in brain levels of acetylcholine. Theoretically, concomitant use of choline and atropine may decrease the effects of atropine.

Likelihood Possible Evidence D

Vitamin K21 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.

Does OSAplex MK-7 by XYMOGEN interact with any medications?
Yes. Based on its ingredients, OSAplex MK-7 has a known interaction with 793 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
OSAplex MK-7 contains 8 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.
Is it safe to take this during pregnancy?
Vitamin D3 and vitamin K2 are likely safe at recommended doses during pregnancy, and calcium is likely safe when you stay within the recommended amount. Choline is also likely safe in pregnancy. However, silicon safety data in pregnancy is insufficient — there isn't enough information to say either way. Talk with your doctor or pharmacist before starting, especially if you have any pregnancy-related concerns or already take prenatal vitamins.
Can I take this while breastfeeding?
Vitamin D3, vitamin K2, calcium, and choline are all likely safe while breastfeeding at recommended amounts. Silicon safety during breastfeeding isn't well established, so it's best to discuss this with your doctor or pharmacist first to make sure it's right for you and your baby.
What are the most common side effects?
At recommended doses, calcium is most likely to cause mild digestive upset — belching, constipation, diarrhea, gas, or stomach discomfort. Choline at high doses (well above what's in this product) can cause a fishy body odor and nausea. Vitamin D3 and vitamin K2 are generally well tolerated. If you have digestive sensitivity, take it with food or separate doses.
How does this help bones?
Vitamin D3 helps your body absorb and use calcium. Calcium is the main mineral that gives bone its strength. Vitamin K2 helps direct calcium to bone and supports bone mineralization. Microcrystalline hydroxyapatite is a form of calcium that closely matches bone's own mineral structure. Together, they provide the building blocks and cofactors your bones need. Silicon and choline play supporting roles in bone and connective tissue health.
Should I take this at a specific time of day?
The product facts don't specify an ideal time. However, because calcium can interfere with the absorption of some medications (like thyroid hormone and certain antibiotics), it's smart to separate this product and those drugs by several hours — typically taking your medication first thing in the morning and this supplement at lunch or dinner. Ask your pharmacist to tailor the timing to your specific prescriptions.
Can I take this with other supplements or vitamins?
The product facts don't address interactions with other supplements. Because this product contains calcium, vitamin D, and vitamin K, check with your doctor or pharmacist before combining it with other bone-support or multivitamin products to avoid getting too much of any single nutrient.
