HelloPharmacist Scorecard of Bio-K Forte Caps by Biotics Research Corporation

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 16, 2026

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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Bio-K Forte Caps contains 3 active ingredients: Superoxide Dismutase, Catalase, and Vitamin K. Vitamin K is a fat-soluble vitamin that plays a central role in blood clotting and bone health.

The product also contains inactive ingredients — a capsule shell and magnesium stearate — that help deliver the actives.

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: vitamin K for blood clotting and bone health.
  • We looked for evidence on: Hemorrhagic disease, Hypoprothrombinemia, Vitamin K-dependent clotting factors deficiency (VKCFD), Warfarin anticoagulation, Osteoporosis, vitamin K deficiency — and 1 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 in this product is effective for treating vitamin K deficiency and supporting normal blood clotting. It's also possibly effective for bone health and osteoporosis.

We don't have effectiveness data on file for Superoxide Dismutase or Catalase, so we can't speak to what those ingredients do in this formulation.

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.

Vitamin K taken by mouth is generally well tolerated in healthy people at dietary levels. The most common side effects are mild gastrointestinal ones — nausea, stomach upset, and diarrhea.

Because vitamin K interacts with blood thinners, check with your doctor before taking a supplement, even though normal food sources are fine. Vitamin K is considered likely safe during pregnancy and while breastfeeding, but talk with your doctor or pharmacist about whether this product is right for you at that time.

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.

If you take warfarin (Coumadin) or any other blood thinner, this product requires a conversation with your doctor or pharmacist first — vitamin K can reduce how well these medications work. For the other two ingredients in this formula, we hold no interaction data, so we can't check them against your medications.

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.

Bio-K Forte Caps may be worth considering if you want vitamin K support and don't take blood thinners like warfarin. If you do take warfarin or any other blood thinner, or if you take any prescription medication, check with your doctor or pharmacist before starting this product.

We couldn't verify the safety or effects of the other two ingredients in the formula.

Bio-K Forte Caps by Biotics Research Corporation: Common Questions

Does Bio-K Forte Caps by Biotics Research Corporation interact with any medications?
Yes. Based on its ingredients, Bio-K Forte Caps 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?
Bio-K Forte Caps contains 3 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.
Will this work if I'm low on vitamin K?
Yes — vitamin K is effective for treating vitamin K deficiency and supporting normal blood clotting. It may also help with bone health, though the evidence there is less established.
Can I take this if I'm on warfarin?
No — not without talking to your doctor first. Vitamin K directly weakens warfarin's ability to thin your blood. You need personalized guidance before taking any supplement with this ingredient.

We don't have effectiveness data on file for those ingredients in our system, so we can't tell you what role they're meant to play in this formula.
