HelloPharmacist Scorecard of Pycnogenol 150 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 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.

Pycnogenol 150 mg contains one active ingredient: maritime pine bark extract, standardized as Pycnogenol. It's the sole therapeutic component in this capsule.

The product also contains inactive ingredients — microcrystalline cellulose, cellulose, water, and calcium palmitate — which serve as fillers and binders to hold the capsule together.

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: Antioxidant support and circulation health.
  • We looked for evidence on: Chronic venous insufficiency (CVI), Varicose veins, Hypertension, Atherosclerosis, Hyperlipidemia, Aging 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.

Maritime pine bark extract is possibly effective for osteoarthritis and chronic venous insufficiency (CVI), a condition where veins have trouble returning blood from the legs. It's also rated possibly effective for asthma.

However, for high cholesterol (hyperlipidemia), the evidence rates it as possibly ineffective, so it's not a reliable choice 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.

Maritime pine bark extract is generally well tolerated in studies, though long-term safety hasn't been fully established. The most common side effects reported orally are gastrointestinal complaints, dizziness, and vertigo; headache has also been reported in a single trial.

Two isolated cases of chest pain and heart failure worsening were reported in patients with prior heart disease, but it's unclear whether the extract directly caused these events. There isn't enough safety data to use this product during pregnancy or while breastfeeding — the facts advise against it.

Talk with your doctor or pharmacist for personalized guidance if you're pregnant, planning pregnancy, or nursing.

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, check with your pharmacist if you take blood thinners or antiplatelet drugs (Moderate interaction), immunosuppressants (Moderate interaction), or diabetes medications (Moderate interaction). Maritime pine bark extract may increase bleeding risk, reduce immunosuppressant effectiveness, or lower blood sugar unpredictably.
