HelloPharmacist Scorecard of Pine Bark Extract 95% Proanthocyanidins by Hard Rhino
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
This product contains one active ingredient: maritime pine bark extract standardized to 95% proanthocyanidins. Proanthocyanidins are plant compounds with antioxidant properties.
The product is a powder with no other inactive ingredients listed.
Does it work?
Moderate evidence
Pine bark extract has Possibly Effective ratings for osteoarthritis and chronic venous insufficiency (a condition where blood doesn't return well from the legs). It's rated Possibly Ineffective for high cholesterol.
The evidence for asthma is listed as Possibly Effective, though it's generally not a first-line treatment. Keep in mind these ratings mean the evidence is suggestive but not conclusive—more research would help clarify how well it works.
How safe is it?
Well-documented data
Maritime pine bark extract is generally well tolerated in studies, though long-term safety data isn't fully established. The most common side effects reported are gastrointestinal complaints, dizziness, and vertigo.
Headache and a single case of chest pain have also been reported, though the chest pain occurred in a patient with a history of heart problems and may not have been directly caused by the extract. There isn't enough safety data during pregnancy or breastfeeding, so it's best to avoid it at those times.
Meds to double-check
Moderate interaction found
Before taking this product, check with your pharmacist if you're on blood thinners or antiplatelet drugs—pine bark extract may increase bleeding risk (Moderate severity). Also double-check if you take diabetes medications or immunosuppressants, as the extract may affect how those work.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
This extract may help with osteoarthritis or venous leg symptoms if you're looking for a possibly effective option. If you take blood thinners, diabetes drugs, or immunosuppressants, you'll need to check with your pharmacist first—the interaction risks are real.
Talk to us before starting, especially if you're pregnant, breastfeeding, or on any prescription medications.

Pine Bark Extract 95% Proanthocyanidins by Hard Rhino Drug Interactions
HelloPharmacist Interaction Report
Pine Bark Extract 95% Proanthocyanidins by Hard Rhino contains one active ingredient—maritime pine bark extract—that does interact with medications.
Altogether, these interactions span 322 individual medications.
Read the full breakdown — every affected drug type, severity by severity
The most serious concern is with blood thinners and antiplatelet drugs (like warfarin, aspirin, or clopidogrel). Pine bark extract may inhibit platelet aggregation, which theoretically increases your bleeding risk when combined with these medications.
The clinical significance of this effect isn't fully clear, but it's worth taking seriously.
Two other drug types carry Moderate-severity interactions. If you take diabetes medications, pine bark extract might lower your blood sugar further—one clinical study showed this effect in patients already on antidiabetes agents, so close monitoring and possible dose adjustments could be needed.
If you're on immunosuppressants (drugs that deliberately dampen your immune system), this extract might work against them, though this effect has only been seen in lab and animal studies, not yet in humans.
