HelloPharmacist Scorecard of Pine Bark Extract 150 mg by Nutritional Concepts
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.
What’s inside
Full disclosure
Pine Bark Extract 150 mg contains one active ingredient: maritime pine bark extract at 150 milligrams per tablet. The extract is thought to work through compounds that may affect how your blood clots, support blood vessel function, and influence immune and inflammatory responses.
The tablet also contains several inactive ingredients—dicalcium phosphate, stearic acid, magnesium stearate, microcrystalline cellulose, croscarmellose sodium, and silicon dioxide—which are standard binders, fillers, and flow agents used in tablet manufacturing.
Does it work?
Moderate evidence
Maritime pine bark extract is possibly effective for osteoarthritis and chronic venous insufficiency (CVI), a condition where leg veins struggle to pump blood back to your heart. The evidence for these uses comes from clinical trials but isn't yet conclusive.
For lowering cholesterol (hyperlipidemia), the extract is rated possibly ineffective—the research doesn't support a benefit. Evidence for asthma is also listed as possibly effective, though it remains preliminary.
If you're considering this supplement for a specific condition, chat with your pharmacist or doctor about what the current evidence actually shows for your situation.
How safe is it?
Well-documented data
Maritime pine bark extract is generally well tolerated in studies, but long-term safety hasn't been fully established. The most common side effects reported are gastrointestinal complaints, dizziness, and vertigo.
A standardized form of the extract (Pycnogenol) has occasionally caused headache and severe vertigo in trials, and very rarely, cases of chest pain and worsening heart failure were reported—though it's unclear whether the extract was responsible. During pregnancy, the safety data is insufficient; the product is best avoided until more is known.
The same applies to breastfeeding—there isn't enough data to know either way, so talk with your doctor or pharmacist about whether it's right for you. If you're pregnant, planning pregnancy, or breastfeeding, get personalized advice before starting.
Meds to double-check
Moderate interaction found
Before taking this product, double-check if you're on blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel)—moderate risk of increased bleeding. Also flag it with your doctor if you take diabetes medications or immunosuppressants, since the extract may affect how well they work.
Use the medication checker on this page to verify your exact drugs.
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.
This supplement may help with osteoarthritis or leg vein problems, but if you take blood thinners, diabetes drugs, or immunosuppressants, you'll need to check with your pharmacist or doctor first. Long-term safety isn't fully established, so it's worth a conversation before you commit to it long-term.

Pine Bark Extract 150 mg by Nutritional Concepts Drug Interactions
HelloPharmacist Interaction Report
Pine Bark Extract 150 mg by Nutritional Concepts does interact with medications—specifically with blood thinners and antiplatelet drugs.
Maritime pine bark extract, the product's single active ingredient, may increase your bleeding risk when taken alongside blood thinners (anticoagulants) like warfarin or aspirin-type medications (antiplatelets). The research suggests the extract slows platelet clumping, though we're still not sure how much that matters in real life.
Read the full breakdown — every affected drug type, severity by severity
Two other drug groups warrant caution. Maritime pine bark extract may weaken immunosuppressant medications—the kind used after transplants or for immune conditions—because studies show the extract can stimulate immune activity.
Additionally, it might lower blood sugar too much when you're already taking diabetes medications, which could cause low blood sugar (hypoglycemia). If you take diabetes drugs, you'd want to monitor your blood glucose closely and talk to your doctor about dose adjustments.
Altogether, these interactions span 322 individual medications. The safest move is to run your exact medications through the checker below before you start.
