HelloPharmacist Scorecard of Vanadium 100 mcg by Kirkman

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 11, 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 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: vanadium chelate, a form of the mineral vanadium. Vanadium is a trace element involved in insulin function and bone health.

The inactive ingredients are plant-based cellulose, L-leucine, and a plant cellulose capsule.

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

This product doesn't appear to be marketed for a specific use, so we graded Vanadium's overall clinical evidence instead.

Strong

Strong clinical evidence supports Vanadium for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Vanadium deficiency — rated "Likely Effective" (Natural Medicines).

The evidence we have shows vanadium is likely effective for vanadium deficiency—which is rare. For athletic performance, diabetes, high cholesterol, and cancer, the evidence is too limited to rate whether vanadium supplements actually work.

The small studies we do have don't yet prove benefit in those areas.

The evidence, ingredient by ingredient Vanadium

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.

Vanadium from food is fine, but supplement doses can cause problems and may be toxic at high levels. Doses below 1.8 mg daily are generally well tolerated orally.

Higher doses may trigger gastrointestinal upset—belly discomfort, diarrhea, gas, and nausea. Rarely, long-term high-dose use has been linked to kidney damage.

Allergic reactions to vanadium metal are possible; a few cases have been reported of itchy rashes, eye itching, and contact dermatitis in people exposed to vanadium-containing objects or tools. There is not enough safety data to use vanadium supplements during pregnancy or while breastfeeding—talk with your pharmacist or doctor before use if you're pregnant or nursing.

Side effects, ingredient by ingredient Vanadium

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Vanadium.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 208 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 your medications with our tool below if you take blood thinners or antiplatelet drugs (Moderate risk of increased bleeding) or diabetes medications (Moderate risk of low blood sugar). Vanadium may strengthen both types.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This product is a single-ingredient supplement for people with vanadium deficiency (uncommon). If you take blood thinners, antiplatelet drugs, or diabetes medications, check with your pharmacist before starting—vanadium may intensify their effects.

Pregnant and breastfeeding people should avoid it pending more safety data.

Vanadium Chelate2 drug types · 208 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, vanadium might increase the risk of bleeding when taken with anticoagulant/antiplatelet drugs.
In vitro research shows that the sodium orthovanadate form of vanadium prolongs clotting time, likely through inhibition of thrombin and factor Xa.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, vanadium might increase the risk of hypoglycemia when taken with antidiabetes drugs.
A few very small clinical studies in patients with type 2 diabetes show that the vanadyl sulfate form of vanadium increases insulin sensitivity and might lower blood glucose levels.

Vanadium 100 mcg by Kirkman: Common Questions

Does Vanadium 100 mcg by Kirkman interact with any medications?
Yes. Based on its ingredients, Vanadium 100 mcg has a known interaction with 208 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Vanadium 100 mcg 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.
Is vanadium safe for pregnant or breastfeeding people?
No. There isn't enough safety information, so vanadium supplements should be avoided during pregnancy. Safety is also unknown while breastfeeding. Talk with your pharmacist or doctor for personalized advice if you're pregnant or nursing.
Can vanadium help with diabetes?
The evidence doesn't establish that it works. A few very small trials in type 2 diabetes patients showed vanadium can increase insulin sensitivity and might lower blood sugar in lab settings, but we don't have enough reliable data to say supplements help in real life.
What are the most common side effects?
Vanadium is well tolerated at doses below 1.8 mg daily. Higher doses may cause gastrointestinal upset—belly discomfort, diarrhea, gas, and nausea. Rarely, long-term high-dose use has been linked to kidney damage.
Can I be allergic to vanadium?
Yes, though true allergic reactions are uncommon. A few cases have been reported of itchy rashes, eye itching, and contact dermatitis in people exposed to vanadium-containing objects. If you develop a rash or itching after starting this supplement, stop and call your pharmacist.
Does this contain any fillers?
The active ingredient is vanadium chelate. The inactive ingredients are plant-based cellulose, L-leucine, and a plant cellulose capsule—standard excipients that help make and deliver the supplement.
