HelloPharmacist Scorecard of Pycnogenol 100 mg by Healthy Origins

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 Sep 3, 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 a single active ingredient: Pycnogenol, a standardized extract from maritime pine bark. It's a polyphenol-rich compound used to support blood flow, joint health, and immune function.

The capsule itself is made from plant-based cellulose, and calcium palmitate is included as an inactive binder.

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: Nature's super antioxidant for circulation and vein health.
  • We looked for evidence on: Chronic venous insufficiency (CVI), Varicose veins, Raynaud syndrome, Hemorrhoids, Hypertension, Atherosclerosis — and 4 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 "Insufficient Reliable Evidence To Rate" for Aging skin, Atherosclerosis, Hemorrhoids, Hypertension, and more.

Maritime pine bark extract (Pycnogenol) is possibly effective for osteoarthritis and chronic venous insufficiency — a condition marked by poor blood return from the legs. The evidence for asthma is also rated possibly effective.

For high cholesterol (hyperlipidemia), the research suggests it's possibly ineffective, so don't rely on it for that purpose.

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.

Pycnogenol is generally well tolerated in studies, though long-term safety hasn't been fully established. The most common side effects reported are gastrointestinal complaints, dizziness, and vertigo.

Headache and isolated cases of chest pain or worsening heart failure have been reported, though it's unclear whether the extract directly caused these in the patients who experienced them. There isn't enough safety data to know whether Pycnogenol is safe during pregnancy or breastfeeding.

If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before taking this product — they can weigh the potential benefits against the unknowns for your individual situation.

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 taking this product, confirm with your pharmacist or doctor if you're on blood thinners or antiplatelet drugs (like warfarin or aspirin), diabetes medications, or immunosuppressants. Maritime pine bark extract may increase bleeding risk, lower blood sugar unpredictably, and reduce immunosuppressant 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.

Pycnogenol may help with joint pain and leg swelling from poor circulation, but it can interact with blood thinners, diabetes drugs, and immunosuppressants, and its long-term safety record isn't solid. If you take any of those medication types — or any prescription medication at all — check your specific drugs with your pharmacist or doctor before starting.

Dizziness and stomach upset are the most common side effects to expect.

Pycnogenol 100 mg by Healthy Origins: Common Questions

Does Pycnogenol 100 mg by Healthy Origins interact with any medications?
Yes. Based on its ingredients, Pycnogenol 100 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 100 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.
What is Pycnogenol, and what's it used for?
Pycnogenol is a standardized extract from maritime pine bark — the plant source is also called Maritime Pine. It's used mainly for osteoarthritis and chronic venous insufficiency, a condition where blood doesn't flow back up from your legs as well as it should. Some people take it for asthma, though the evidence for that is still building.
Can I take Pycnogenol if I'm on a blood thinner like warfarin or aspirin?
Not without checking with your doctor or pharmacist first. The extract may slow blood clotting, which could raise your bleeding risk when combined with blood thinners or antiplatelet drugs. Your provider can assess whether it's safe for you specifically and whether you need any monitoring.
What side effects might I notice?
Stomach upset, dizziness, and vertigo are the most common. Headache has been reported in some trials. In very rare cases, chest pain and worsening heart failure have been noted, though it's not clear the extract caused them. Stop and contact your doctor if you develop chest pain or new shortness of breath.
Is it safe to take while I'm pregnant or breastfeeding?
There isn't enough safety data either way. The evidence doesn't advise against it in pregnancy (it's rated possibly safe), but we simply don't know enough. If you're pregnant, planning to conceive, or breastfeeding, talk with your doctor or pharmacist before starting — they can help you decide what's right for you.
I'm on a diabetes medication — is Pycnogenol okay for me?
Not without checking with your doctor first. One clinical study found that maritime pine bark extract can lower blood sugar in people already taking diabetes drugs, so adding it could push your levels too low. Your doctor may want to monitor your blood glucose closely and might adjust your medication dose.
Does Pycnogenol actually work for joint pain?
The research suggests it's possibly effective for osteoarthritis. That means there's some clinical evidence supporting its use, but the evidence isn't definitive yet. Results vary from person to person, so you might benefit or you might not — talk with your doctor about whether to try it as part of your overall joint care plan.
