HelloPharmacist Scorecard of Pycnogenol 30 mg by Spring Valley

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: Pycnogenol, a standardized extract from maritime pine bark. The capsule itself is made from cellulose and gelatin, with less than 2% of other inactive ingredients.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Maritime Pine's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: support skin health.
  • We looked for evidence on: Aging skin, Wrinkled skin, Melasma, Photoaging, Skin elasticity, Skin hydration.
  • The closest evidence on file: Maritime Pine is rated "Insufficient Reliable Evidence To Rate" for Aging skin (Natural Medicines).
  • Also on file: Maritime Pine is rated "Insufficient Reliable Evidence To Rate" for Melasma, Wrinkled skin.

The data shows Pycnogenol is possibly effective for osteoarthritis and chronic venous insufficiency (swelling and discomfort in the legs from poor circulation). For asthma, it's also rated possibly effective.

For high cholesterol, the evidence suggests it's possibly ineffective, so it's not a reliable choice for that goal.

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 are gastrointestinal upset, dizziness, and vertigo.

A single case of chest pain and one report of worsening heart failure have been documented, though it's unclear whether the extract caused these — both patients had existing heart conditions. Because there isn't enough safety data, it's best avoided during pregnancy and while breastfeeding.

Talk with your pharmacist or doctor before using it if you're pregnant, nursing, or have heart disease.

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 start Pycnogenol, check if you take blood thinners or antiplatelet drugs (like warfarin or aspirin) — it may increase bleeding risk. Also double-check if you're on immunosuppressants (for transplants or autoimmune conditions) or diabetes medications, as the extract could interfere with both.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Pycnogenol may help with osteoarthritis and leg swelling, but it's not the right choice for high cholesterol. If you take blood thinners, immune-suppressing drugs, or diabetes medications, check with your pharmacist first — the extract can interact with all three.

Avoid it in pregnancy and while nursing.

Pycnogenol 30 mg by Spring Valley: Common Questions

Does Pycnogenol 30 mg by Spring Valley 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 this help my osteoarthritis?
Possibly. The data rates Pycnogenol as possibly effective for osteoarthritis. It's worth a try, but talk to your doctor if you're not seeing results after a reasonable period.
Can I take this if I'm pregnant?
No — there isn't enough safety data in pregnancy, so it's best avoided. Talk with your doctor before using it if you're pregnant or planning to be.
What are the side effects?
Most common are stomach upset, dizziness, and vertigo. A few people reported headache. Rare cases of chest pain or heart failure worsening have been reported, but those patients had existing heart disease, so it's unclear if the extract was the cause.
Is this safe long-term?
The extract is generally well tolerated in studies, but long-term safety hasn't been fully worked out. If you're taking it regularly, check in with your pharmacist periodically.
Can I use this for high cholesterol?
No — the data rates it as possibly ineffective for cholesterol, so it's not a reliable choice for that goal. Stick with medications or other approaches your doctor recommends.
What does Pycnogenol actually do?
It's a standardized extract from maritime pine bark. Research suggests it may help reduce joint inflammation and improve circulation, but the exact mechanisms aren't completely clear yet.
