Recommended dosage of pine bark extract for erectile dysfunction.

Pine bark extract is studied for ED at roughly 40-120 mg/day, often with L-arginine; evidence is limited. Ask a doctor.

Pine bark extract (often sold as Pycnogenol) is a supplement studied for erectile dysfunction, typically at doses around 40–120 mg per day in research, often combined with L-arginine. The evidence is limited and it is no substitute for prescription treatment. Any dose should be discussed with a doctor. This article explains what is known about its use and dosage.

It is a topic in our erectile dysfunction section.

What pine bark extract is

Pine bark extract is a plant-derived antioxidant, the best-known branded form being Pycnogenol. It is thought to support nitric oxide and blood-vessel function — the same pathway involved in erections — which is why it has been studied for ED.

The doses used in studies

Research has used a range of doses, commonly around 40 to 120 mg of pine bark extract per day, frequently alongside L-arginine. There is no single official "recommended" dose for ED, since it is a supplement rather than an approved drug, and products vary.

What the evidence shows

Some small studies, often pairing pine bark extract with L-arginine, suggest a modest improvement in erectile function. The trials are limited in size and quality, so this is a possible mild aid, not a reliable treatment comparable to a PDE5 inhibitor.

Safety and cautions

Pine bark extract is generally well tolerated but can cause mild digestive upset and may interact with blood thinners or blood-pressure and immune medicines. Supplement quality varies, so choose a reputable product and tell your doctor before starting, especially with other medicines.

Where it fits

Pine bark extract is best seen as an optional supplement within a healthy lifestyle, not a stand-alone cure. If ED persists, see a doctor. For the broader supplement picture, see male enhancement pills.

Supplements: enhancement pills. OTC like Viagra: OTC like Viagra? Aspirin myth: aspirin like Viagra?

How to use it sensibly

If you decide to try pine bark extract, choose a reputable, standardised product, tell your doctor first (especially if you take other medicines), and give it weeks rather than expecting an immediate effect. Treat it as a possible mild support alongside lifestyle measures, not a replacement for proven treatment, and stop if you notice problems.
