HelloPharmacist Scorecard of Vitamin K-2 MK-4 100 mcg by Biophix

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
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 2 active ingredients: vitamin K2 (in the MK-4 form, at 100 mcg per capsule) and alfalfa. Vitamin K2 is a form of vitamin K that supports your body's ability to produce clotting factors and may play a role in bone health.

Alfalfa is a plant used traditionally in supplements, though the evidence for its specific health claims is limited. The capsule also contains three inactive ingredients — cellulose, rice flour, and silica — which are fillers and binders.

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: Support healthy bones and cardiovascular health.
  • We looked for evidence on: Cardiovascular disease (CVD), Osteoporosis, Warfarin anticoagulation, Vitamin K-dependent clotting factors deficiency (VKCFD), Bone density, Vascular calcification.
  • The strongest evidence on file: Vitamin K is rated "Effective" for Warfarin anticoagulation (Natural Medicines).
  • Also on file: Vitamin K is rated "Effective" for Vitamin K-dependent clotting factors deficiency (VKCFD).
  • Also on file: Vitamin K is rated "Possibly Effective" for Osteoporosis.

Vitamin K2 is effective for treating bleeding disorders like hypoprothrombinemia and vitamin K-dependent clotting factor deficiency, and it works to manage warfarin anticoagulation. It is possibly effective for osteoporosis.

Alfalfa, however, has insufficient reliable evidence to support its use for any of the conditions it's marketed for — diabetes, indigestion, high cholesterol, or menopausal symptoms. The data we hold does not establish that alfalfa is proven effective for these purposes.

The evidence, ingredient by ingredient Vitamin K Alfalfa

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.

Vitamin K2 is generally well tolerated when taken by mouth. The most common side effects are mild — diarrhea, nausea, and stomach upset.

The safety data says it is likely safe during pregnancy and lactation. Alfalfa is generally well tolerated in small food amounts, but supplements carry real risks.

In rare cases, chronic alfalfa use has been linked to a lupus-like syndrome. The most common side effects are gastrointestinal: abdominal discomfort, diarrhea, flatulence, and increased stool frequency.

The safety data advises against alfalfa supplements during pregnancy because of its estrogen-like activity. There isn't enough reliable data to know whether it's safe while breastfeeding, so talk with your doctor or pharmacist for personalized advice.

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 — Alfalfa, Vitamin K.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 583 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.

Check with your pharmacist before using this if you take warfarin or another blood thinner (this is Major). Also double-check hormonal birth control, estrogen therapy, diabetes medications, photosensitizing drugs, or immunosuppressants (all Moderate).

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

If you take warfarin or any blood thinner, do not start this product without talking to your pharmacist first — the interaction is serious. If you take birth control, estrogen therapy, diabetes medications, or immunosuppressants, check with your pharmacist before use.

This product is not established to be effective for the conditions alfalfa is often marketed for, so weigh whether the benefit justifies the risk.

Alfalfa6 drug types · 583 drugs

Warfarin (Coumadin)

Theoretically, alfalfa might reduce the anticoagulant activity of warfarin.
Alfalfa contains a large amount of vitamin K. This could theoretically interfere with the activity of warfarin.

Likelihood Probable Evidence D
Antidiabetes Drugs

Theoretically, alfalfa might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that alfalfa decreases blood sugar in diabetic mice. Also, in one case report, a diabetic patient experienced hypoglycemia after consuming alfalfa extract. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, alfalfa might interfere with the activity of contraceptive drugs.
Alfalfa contains coumestrol, a phytoestrogen, and isoflavonoids, which have estrogenic effects.

Likelihood Possible Evidence D
Estrogens

Theoretically, alfalfa might interfere with hormone therapy.
Alfalfa contains coumestrol, a phytoestrogen, and isoflavonoids, which have estrogenic effects.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, alfalfa might decrease the efficacy of immunosuppressive therapy.
In vitro research and human case reports suggest that alfalfa may have immunostimulant effects.

Likelihood Possible Evidence D
Photosensitizing Drugs

Theoretically, concomitant use of alfalfa with photosensitizing drugs might have additive effects.
Animal research suggests that excessive doses of alfalfa may increase photosensitivity, possibly due to its chlorophyll content. It is unclear if this effect would be clinically relevant in humans.

Likelihood Possible Evidence D

Vitamin K-2 MK-4 100 mcg by Biophix: Common Questions

Does Vitamin K-2 MK-4 100 mcg by Biophix interact with any medications?
Yes. Based on its ingredients, Vitamin K-2 MK-4 100 mcg has a known interaction with 583 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?
Vitamin K-2 MK-4 100 mcg 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 — not without talking to your doctor or pharmacist first. Both ingredients in this product can reduce how well warfarin works, which could be dangerous. Your provider may need to adjust your dose or monitor you more closely if you want to use this supplement.
Is it safe during pregnancy?
Vitamin K2 is likely safe in pregnancy, but alfalfa is possibly unsafe because of its estrogen-like effects. Since this product contains both, talk with your doctor or pharmacist before using it during pregnancy.
What are the common side effects?
The most common side effects are gastrointestinal — nausea, diarrhea, stomach upset, abdominal discomfort, and gas. These are usually mild, but if they persist or worsen, let your pharmacist know.
Does alfalfa really work for diabetes or high cholesterol?
According to our data, there isn't enough reliable evidence to say alfalfa is proven effective for diabetes, high cholesterol, or any of the other conditions it's marketed for. The claims are theoretical at this point.
Does this product have any fillers?
Yes. The capsule contains three inactive ingredients — cellulose, rice flour, and silica — which are binders and fillers to hold the supplement together.
