Also known as: Pine bark extract, Pycnogenol, Flavangenol, Pinus pinaster Extract

Overview

Pine bark extracts are derived from the bark of various species of pine trees, primarily *Pinus pinaster*, and they are rich in bioactive compounds, particularly proanthocyanidins and phenolic acids. These extracts are widely recognized for their antioxidant, anti-inflammatory, and potential cardiovascular protective effects. Commonly used in herbal supplements, their applications range from supporting cardiovascular health to enhancing overall antioxidant status. The research surrounding pine bark extracts is at a moderate maturity level, with several clinical trials ongoing, yet there is a strong necessity for more comprehensive, large-scale studies to confirm efficacy and safety. The extract is typically available in capsule or tablet form and has shown promise in addressing conditions related to oxidative stress and cardiovascular risk factors.

Benefits

Pine bark extracts, especially Pycnogenol, have demonstrated significant benefits in cardiovascular health through reductions in both systolic and diastolic blood pressure and improvements in lipid profiles and glycemic control. Studies indicate that individuals with cardiovascular risk factors might particularly benefit from these effects. Evidence supporting antioxidant properties shows increased plasma antioxidant capacity. Additional benefits include potential reductions in inflammation, improvements in erectile dysfunction, and neuroprotection. Effect sizes vary, but notable improvements have been documented, often within weeks of supplementation. However, long-term benefits remain unclear.

How it works

Pine bark extracts exert their effects primarily through their strong antioxidant properties, which involve scavenging reactive oxygen species and enhancing nitric oxide production, vital for cardiovascular health. They may inhibit inflammatory pathways via the NF-kB pathway. The extracts exhibit interaction with the cardiovascular, nervous, and immune systems, targeting enzymes and pathways crucial for maintaining vascular health. The bioavailability of these extracts is favorable, allowing for efficient absorption and metabolism in the body.

Side effects

Pine bark extracts are generally considered safe for consumption, with mild side effects typically occurring in more than 5% of users, including gastrointestinal discomfort, nausea, and dizziness. Less common side effects (1-5%) may include headaches, sleepiness, and urinary retention; rare side effects (<1%) are not well-documented. Individuals on anticoagulant therapy should exercise caution, as the extract may interfere with platelet aggregation. Hypersensitivity to pine bark is also a contraindication for its use. Due to the mild nature of adverse effects, most users tolerate pine bark extracts well, but it's always advisable to consult with healthcare providers before starting supplementation.

Dosage

The minimum effective dose of pine bark extract typically starts at 50 mg per day, with optimal dosage ranges generally lying between 80 mg and 480 mg per day. While the precise maximum safe dose is not well-established, doses up to 480 mg have been utilized safely in studies. There are no specific timing recommendations for administration, and it is available primarily in capsules or tablets. Factors affecting absorption include the presence of other nutrients or medications during intake.
