HelloPharmacist Scorecard of Triple Strength Vitamin K-2 150 mcg Menaquinine-7 by Solaray

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 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 K as menaquinone-7 (a form of K-2), at 150 mcg per capsule. Vitamin K is a fat-soluble vitamin your body uses to make clotting factors (proteins that help blood clot) and to support bone health.

The capsule also contains inactive ingredients — cellulose, glycerol monostearate, magnesium stearate, fermented defatted chickpea flour extract, and silica — which are binders, fillers, and flow agents that hold the supplement together.

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 support and cardiovascular support.
  • We looked for evidence on: Osteoporosis, Cardiovascular disease (CVD), Hemorrhagic disease, Hypoprothrombinemia, Vitamin K-dependent clotting factors deficiency (VKCFD), Warfarin anticoagulation — and 4 related terms.
  • The strongest evidence on file: Vitamin K is rated "Effective" for Hemorrhagic disease (Natural Medicines).
  • Also on file: Vitamin K is rated "Effective" for Hypoprothrombinemia, Warfarin anticoagulation, Vitamin K-dependent clotting factors deficiency (VKCFD).
  • Also on file: Vitamin K is rated "Possibly Effective" for Osteoporosis.

Vitamin K is effective for treating vitamin K deficiency conditions, including low levels of clotting factors (hypoprothrombinemia) and hemorrhagic disease. It's also effective in correcting warfarin anticoagulation when needed medically.

For bone health and osteoporosis, the evidence is possibly effective — it shows promise, but we don't yet have strong proof it prevents or reverses bone loss on its own.

The evidence, ingredient by ingredient Vitamin K

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.

Taken by mouth, vitamin K is generally well tolerated in the amounts found in food and most supplements for healthy people. The most common side effects are mild stomach upset — nausea, diarrhea, and abdominal pain.

Serious side effects are rare. Because of the Major interaction with blood thinners, talk with your doctor before taking any vitamin K supplement, even if you feel fine.

Vitamin K is likely safe during pregnancy and breastfeeding.

Side effects, ingredient by ingredient Vitamin K

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?
  • 1 of the 1 matched ingredient can interact with medications — Vitamin K.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 2 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.

Stop and check with your doctor or pharmacist if you take warfarin (Coumadin) or any blood thinner in its class. Vitamin K directly reduces how these drugs work, and that's a Major interaction.

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.

This supplement is appropriate for people with vitamin K deficiency or those who need to correct warfarin dosing under medical supervision. If you take any blood thinner — prescription or over-the-counter — or if you have a bleeding disorder, talk to your pharmacist or doctor before starting it.

Formula

Discussion: The premium Vitamin K-2 menaquinone-7 used in this formula is derived from chickpea. Menaquinone-7 (MK-7) is known to enjoy a longer half-life than other forms of Vitamin K, and is therefore believed to offer unique benefits to the body. It is intended to support cardiovascular health, bone formation and vascular health.

Triple Strength Vitamin K-2 150 mcg Menaquinine-7 by Solaray: Common Questions

Does Triple Strength Vitamin K-2 150 mcg Menaquinine-7 by Solaray interact with any medications?
Yes. Based on its ingredients, Triple Strength Vitamin K-2 150 mcg Menaquinine-7 has a known interaction with 2 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?
Triple Strength Vitamin K-2 150 mcg Menaquinine-7 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.
Can I take this if I'm on warfarin?
No — not without talking to your doctor first. Vitamin K reverses warfarin's effect and can put you at risk of clots. Your doctor may adjust your dose or monitor you more closely, but this isn't a supplement you add on your own.
What side effects should I expect?
Most people tolerate it well. Mild nausea, diarrhea, or stomach upset happen in some people, but they're usually mild. Serious side effects are rare.
Is this safe to take while pregnant or breastfeeding?
Yes — vitamin K is likely safe during pregnancy and lactation. If you're pregnant or nursing and thinking about a supplement, it's still worth checking with your provider.
Does vitamin K really help with bone health?
It shows promise for osteoporosis, but the evidence isn't strong yet — it's possibly effective. It's not a proven stand-alone treatment, so don't count on it instead of proven bone-health strategies.
Is there just vitamin K in here, or other stuff?
The active ingredient is vitamin K. The capsule also contains binders and fillers like cellulose, magnesium stearate, and silica — that's normal and doesn't change how it works.
