HelloPharmacist Scorecard of Vanadyl Sulfate by Country Life

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 supplement contains one active ingredient: vanadium, in the form of vanadyl sulfate. The capsule also holds inactive ingredients—cellulose, magnesium stearate, and silica—which are fillers and binders that help 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

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 hold shows vanadium is likely effective for vanadium deficiency—a lack of this mineral in your body. For other uses—athletic performance, cancer, type 2 diabetes, and high cholesterol—the research isn't established enough for us to rate it.

The small clinical studies on diabetes did suggest vanadium might lower blood glucose, but that's not the same as proven effectiveness for treating diabetes.

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 is well tolerated when you stay below 1.8 mg daily. Higher doses may cause stomach upset—nausea, diarrhea, gas, and belly discomfort.

Over the long term at high doses, there's a rare risk of kidney damage. Allergic reactions to vanadium are uncommon but have been reported, showing up as rash, itching, or contact dermatitis in sensitive people.

The safety data advises against taking vanadium supplements during pregnancy and while breastfeeding.

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.

Before you take this, check if you use blood thinners or antiplatelet drugs (Moderate risk of increased bleeding) or diabetes medications (Moderate risk of low blood sugar). These are the two drug types with documented interactions in our data.

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.

Vanadyl Sulfate is mainly useful if you have a vanadium deficiency. If you take blood thinners, antiplatelet drugs, or diabetes medications, talk to your pharmacist before starting this supplement—the interactions could be important.

Stick to low doses and watch for stomach upset.

Vanadium2 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.

Vanadyl Sulfate by Country Life: Common Questions

Does Vanadyl Sulfate by Country Life interact with any medications?
Yes. Based on its ingredients, Vanadyl Sulfate 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?
Vanadyl Sulfate 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.
Does this really help with blood sugar?
The small studies we have suggest vanadium might lower blood glucose and improve insulin sensitivity, but we don't have enough evidence to say it's proven for treating diabetes. If you're diabetic and interested, talk to your doctor first—especially since it could lower your blood sugar further if you're already on diabetes drugs.
What dose is safe?
Vanadium is well tolerated up to 1.8 mg daily. Above that, you risk stomach problems like nausea, diarrhea, and gas. Long-term high doses carry a rare risk of kidney damage.
Can I take this while pregnant or breastfeeding?
The safety data advises against vanadium supplements during pregnancy and while breastfeeding. If you're planning to become pregnant or are nursing, skip this supplement and talk to your doctor about alternatives.
What is vanadium used for?
Vanadium deficiency—when your body doesn't get enough of this mineral—is the one use we have solid evidence for. It's been studied for athletic performance, diabetes, cancer, and high cholesterol, but the research isn't strong enough yet to say it works for those.
What are the side effects?
Most people don't have problems at the recommended dose, but higher amounts can cause stomach upset—nausea, diarrhea, gas, and belly discomfort. Allergic reactions are rare but possible and may show up as rash or itching.
