HelloPharmacist Scorecard of Pycnogenol 30 mg by The Vitamin Shoppe

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

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: Pycnogenol French Maritime Pine bark extract, 30 mg per capsule. It's a standardized extract from the bark of French Maritime pine trees, used in research and marketed as a single-ingredient supplement.

The capsule also includes inactive ingredients — rice flour, gelatin, magnesium stearate, and silicon dioxide — which are common binders and fillers that help form and stabilize the capsule.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: cardiovascular health, skin health, and antioxidant support.
  • We looked for evidence on: Atherosclerosis, Chronic venous insufficiency (CVI), Hypertension, Hyperlipidemia, Aging skin, Wrinkled skin — and 3 related terms.
  • The strongest evidence on file: Maritime Pine is rated "Possibly Effective" for Chronic venous insufficiency (CVI) (Natural Medicines).
  • Also on file: Maritime Pine is rated "Possibly Ineffective" for Hyperlipidemia.
  • Also on file: Maritime Pine is rated "Insufficient Reliable Evidence To Rate" for Aging skin, Atherosclerosis, Hypertension, Varicose veins, and more.

Pycnogenol shows possibly effective evidence for osteoarthritis and chronic venous insufficiency (swelling and pain in the legs from poor blood flow). For asthma, the data rates it possibly effective as well.

For high cholesterol (hyperlipidemia), the evidence suggests it is possibly ineffective — meaning studies haven't shown a clear benefit. The research on each of these uses is still emerging, so results aren't yet definitive.

The evidence, ingredient by ingredient Maritime Pine

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.

Maritime pine bark extract is generally well tolerated in studies, though long-term safety data is limited. The most common side effects reported orally are gastrointestinal complaints, dizziness, and vertigo — dizziness and severe vertigo have appeared in standardized extract trials, and headache has been reported in at least one study.

A single case of chest pain and one report of worsening heart failure were noted in patients taking a standardized maritime pine bark extract (Pycnogenol brand), but both had existing heart conditions and it's unclear whether the extract caused these events. Safety data in pregnancy and breastfeeding is not sufficient to know whether it's safe, so it's best avoided during pregnancy and while breastfeeding unless your doctor advises otherwise.

Side effects, ingredient by ingredient Maritime Pine

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 — Maritime Pine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 327 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 product, check with your doctor or pharmacist if you use blood thinners or antiplatelet drugs (like warfarin or aspirin) — maritime pine bark extract may increase bleeding risk. If you take diabetes medications, let them know, since this extract may lower blood sugar further.

Anyone on immunosuppressants should also confirm it's okay, as the extract might reduce their effectiveness.

The bottom line

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

If you have osteoarthritis or chronic venous insufficiency, this extract has some supporting evidence worth discussing with your doctor. Because it may thin your blood, lower blood sugar, or interfere with immune-suppressing drugs, you'll need to check your exact medications before starting — especially if you take blood thinners, diabetes medications, or immunosuppressants.

Talk it over with your own doctor or pharmacist before adding it to your routine.

Pycnogenol 30 mg by The Vitamin Shoppe: Common Questions

Does Pycnogenol 30 mg by The Vitamin Shoppe interact with any medications?
Yes. Based on its ingredients, Pycnogenol 30 mg has a known interaction with 327 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Pycnogenol 30 mg 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.
Will Pycnogenol actually help my joint pain?
Research suggests it's possibly effective for osteoarthritis, so it may help some people — but evidence is still being built. Whether it'll work for you is individual. Talk with your doctor about whether it's worth trying alongside your current plan.
What are the most common side effects?
Gastrointestinal complaints, dizziness, and vertigo are the side effects most often reported in studies. Headache and severe vertigo have also been noted. Most people tolerate it well, but these are worth watching for when you start.
Is it safe to take during pregnancy or while breastfeeding?
There isn't enough safety data to know either way. The facts advise against use in both pregnancy and breastfeeding. Talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to become pregnant, or breastfeeding.
Why can't I take this with blood thinners?
Maritime pine bark extract may slow how your blood platelets clump together, which could increase your bleeding risk if you're already on a blood thinner. The effect isn't fully proven in real patients, but it's a caution worth taking seriously — your doctor or pharmacist needs to know about both before you combine them.
Does this work for high cholesterol?
No — research suggests Pycnogenol is possibly ineffective for high cholesterol, meaning studies haven't shown it helps with that problem. If you're hoping to lower your cholesterol, this isn't supported by the evidence.
